自动继电器控制器的自适应保护 Automatic adaptive protection relay controller

发明领域本发明总体上涉及电力发送系统领域。 Relates to the field of electric power transmission system Field of the Invention The present invention generally. 更具体地,本发明涉及自动继电器。 More particularly, the present invention relates to an automatic relay.

发明背景几乎任何电力发送系统中的共同问题是电力供应的瞬时中断,例如由瞬时短路造成。 BACKGROUND OF THE INVENTION Power transmission system in almost any common problem is that the instantaneous power supply interruption, for example caused by a momentary short circuit. 举例说来,电线杆之间的电力线在风的作用下会晃动,就有可能相互之间或与地之间发生瞬时的接触。 For example power line, between the poles under the action of the wind will shake, there may occur an instantaneous contact between each other or to ground. 某些东西下落时可能通过裸露的电线区,就可能发生电弧放电,或者发生可以引起瞬时电力线短路或电流激增的其他短时行为,导致保险丝的熔断或继电器的跳闸。 Some things may be through the bare wire zone, arcing can occur when you fall, or the occurrence of other short-term behavior can cause a short circuit or current instantaneous power line surge, resulting in blown fuses or tripping relays. 这些故障大都是自校正过程,并不需要永久的保险丝或自动继电器保护,因为它们很快就结束了。 These failures are mostly self-correcting process, does not require a permanent fuse or automatic relay protection, because they soon ended. 如果保险丝烧断或者继电器跳闸,供电线路就会断开或者用户就会得不到电力供应。 If the fuse is blown or tripped relay, power lines will be disconnected or the user will not get power supply. 那么接下来就需要换保险丝或重置继电器,这样就增加了使用成本。 So then you need to change the fuse or reset the relay, thus increasing the cost.

自动继电器是一种故障中断设备,用来检测电流、电压以及/或者频率并将供电支流的故障区域加以隔离。 Automatic relay is a fault interrupt device for detecting current, voltage and fault regional / or frequency and isolate power tributaries. 一台自动继电器控制设备操纵一个自动继电器,它可以是一个电子控制器。 An automatic relay control device to manipulate an automatic relay, it can be an electronic controller. 自动继电器接在供电线路中用来保护电力发送系统。 Automatic relay connected to the supply line to protect the power transmission system.

更具体地讲,自动继电器是机电设备,和电路断路器相似。 More specifically, the automatic relay is an electromechanical device, and circuit breakers similar. 自动继电器分布于电力线路上的一个或多个位置,典型情况是向上连接一保险丝。 Automatically distributed to one or more of the relay power line location, typically a fuse is connected up. 当自动继电器检测到一种故障状态时,自动继电器就会开始中断。 When the automatic relay detects a fault condition, the relay will start automatically interrupted. 换一句话说,当故障状态没有在固定的时间段内自动排除的话,继电器控制器就会发动跳闸来打开自动继电器,固定时间段的长度是电流的函数。 In other words, when the fault condition is not automatically excluded from the fixed period of time, then the controller will initiate tripping relay to turn on automatic relay, the length of a fixed period of time is a function of current. 然后,通过一段时间延迟后,就像名字中说的那样,自动继电器将会重新闭合,如果故障状态已经排除的话,电力供应就会恢复。 Then, after a time delay, as the name says it, automatic relay will be closed again if the fault condition has been excluded, then the power supply will be restored. 但是,如果故障状态没有排除的话,自动继电器控制器就会在第二个固定时间段后打开继电器。 However, if a fault condition does not exclude the case, the controller will automatically open the relay after the relay in the second fixed period of time. 如果经过事先设定次数的重新闭合操作以后,故障状态仍未排除,继电器控制器将永久断开继电器(亦即永久断开电路)。 If, after a preset number of times after the re-closing operation, the fault condition persists, the controller will permanently disconnect relay relay (ie permanently open the circuit). 电路将保持断开状态直到系统被修复以及/或者故障状态得以排除。 The circuit will remain disconnected until the system is repaired and / or fault conditions can be ruled out.

这样,自动继电器的一个主要作用就是节省保险丝。 Thus, a major role is to save automatically relay fuse. 通常来讲,这个过程是这样实现的,自动继电器检测电流的峰值并在保险丝融化之前断开电路。 Generally, this process is achieved, the relay automatically detects the peak current and open the circuit before the fuse melts. 经过一段时间延迟后,自动继电器闭合,系统供电得到恢复直到下一个故障状态被检测到。 After a period of time delay relay closes automatically, the system power supply was restored until the next fault condition is detected.

保险丝的融化及电流中断的速度是可熔元件的一个加热函数。 Melt and fuse current interruption speed fusible element is a heating function. 加热的速度正比于故障产生的能量,每一种保险丝都有一个时间电流特征,它描述了中断故障电流所要求的时间段长度。 The heating rate is proportional to the energy generated by the fault, each time a fuse has a current characteristic, which describes the fault current interruption time required length. 时间段的长度一般与故障电流的平方根大约成反比。 And the length of time period is generally approximately inversely proportional to the square root of the fault current. 这就要求按被保护的保险丝来调整自动继电器以保证在被保护的保险丝熔化以前自动继电器能断开临时的故障电流。 This requires to be protected by a fuse relay automatically adjusts to ensure that the protected fuse melts before the relay can automatically disconnect a temporary fault current. 这通常是在估计检测到的故障电流的峰值的平方根的平均值的情况下进行的。 This is usually the case in the estimation of faults detected current average value of the square root of the peak conducted.

有一点必须明白的是,不是出现在电网中的所有的故障都为暂时的,比如由于树枝暂时掉在电线上造成的故障。 One thing you must understand is that not all the fault occurs in the power grid are temporary, such as temporarily due to branch out on the wire caused by the failure. 有些故障更多地具有长时间的特性,例如由于暴风雪造成整个电线杆倒塌时的故障。 Some faults more of a long feature, for example due to the storm caused the collapse of the entire fault when a telephone pole. 为此,自动继电器做成在锁定断开状态前的一段时间内仅进行有限次数的跳闸行为的型式。 To this end, the relay automatically formed over a period of time before the lock OFF state tripping behavior pattern performed only a limited number. 如果不这样做的话,继电器将无限循环直到损坏,而被保护的保险丝也会烧断。 If you do not do so, the relay will infinite loop until damage, but also blown fuse protected.

在某些故障电流条件下,采用立刻中断电流的方式比遵循时间电流反比关系中断更适合。 Under certain fault current conditions, using immediately interrupt the current way than to follow an inverse relationship between the time the current interruption is more suitable. 对于中等水平,从电力发送的观点看,允许故障电流维持一段限定的时间,并把故障位置烧断或将保险丝烧断可能比较合适。 For the medium level, from the viewpoint of the power transmission point of view, to allow the fault current is maintained for a limited period of time, and the fault location or blown fuse blows may be more appropriate. 许多自动继电器有多种时间电流反比特性可供选择来实现这种功能。 Many automatic relay time current is inversely proportional to feature a variety of options to achieve this functionality. 典型地,一个自动继电器一般提供两个遵循快速时间电流特性的跳闸操作和两个附加的、在锁定断开状态前遵循一种更慢的时间电流特性的操作。 Typically, an automatic relay generally offer two follow fast time-current characteristics of the trip and two additional operations in the off state before locking operations follow a slower time current characteristics. 在三相系统中,传统的自动继电器在检测到三相中的任意一相发生故障时会把三相的电同时断开。 While the three-phase power will disconnect when the three-phase system, any conventional automatic relay detects a fault in one phase of a three-phase occurs. 其他三相系统则采用在每一相中安装一单独自动继电器的形式。 Other three-phase system is used to install a separate phase automatic relay in each form. 在这些系统中,每个单独的自动继电器都是单独控制的。 In these systems, each individual relay automatically controlled individually. 这样做造价高,不允许各相之间相互响应。 This high cost, does not allow mutual response between each phase.

这样,在一种典型的结构里,对于故障,自动继电器会打开来清除它。 Thus, in a typical structure where, for the failure, the relay will open automatically to clear it. 注意到,对于任何故障,亦即单相—地故障、相—相故障、相—相—地故障以及三相故障,一个典型的自动继电器将断开所有的三相。 Note that for any failure, namely single phase - ground faults, phase - phase failure, phase - phase - earth faults and three-phase fault, a typical automatic relay will disconnect all three phases. 对于供电支流,由于单相的问题而断开所有三相的电会造成更多的不必要的用户也掉电。 For power tributaries, due to the problem of single-phase and three-phase disconnect all electrical cause more unnecessary user also powered down. 然而,如果在发送系统里采用的是传统的单相自动继电器保护的话,就要用到三个独立的单相机械继电器——每一相一个。 However, if the sending system uses a conventional single-phase automatic relay protection, it is necessary to use three separate single-phase mechanical relays - one for each phase. 它为单相故障提供了一种单相方法,但是,如果发生的是展开型故障的话,比方说,两相或三相发生了故障,那时,跳闸和接下来的重新闭合却一直只发生在一相上。 It provides for a single-phase fault a single-phase method, however, if there is an open-type fault if, say, two or three phases fails, then, the next trip and reclose has been only occurs on one phase. 完全独立的单相自动继电器也有可能陷入到赛跑状态中去。 Completely independent single-phase automatic relay is also possible to go into the race condition. 对于相—相故障,如果其中一相的动作比另一相快,那么自动继电器就不可能正确地将另一相也断开。 For phase - phase faults, if the phase to which the action is faster than the other, then it is impossible to rightly automatic relay will also disconnect the other phase.

自动继电器控制器为自动继电器提供智能,能够使自动继电器检测超量的电流,选择计时操作,为跳闸及重新闭合计时以及锁死。 Automatic relay controller provides intelligent automatic relay, enabling automatic detection of excess current relay, select the timing operation for the trip and reclose timing and locked. 液压单元——自动继电器的一个整体部件被用在所有的单相自动继电器中,在三相继电器中的使用率则低一些。 Hydraulic unit - an integral part of the automatic relay is used in all of the single-phase auto relays, three-phase relays usage is lower. 电子控制器通常用在单相继电器中,而在三相继电器中的使用率则更高。 Electronic controller is usually used in a single-phase relay, while usage in the three-phase relay is even higher. 这些设备,应该适当地规划,以一种预先定义好的方式进行调整,以便电力发送系统在发生线路问题时能按期望的方式反应。 These devices should be properly planned, in a predefined way to adjust to the power transmission system is able to respond in the desired manner when the line problems.

一般地,当自动电路继电器被用来与保险丝相连时,可以设定为各种各样的模式。 Generally, when the relay is used for automatic circuit connected to the fuse, you can set a variety of patterns. 举例说来,自动继电器或自动闭合断路器既可以设定为保全保险丝的模式也可以设定为烧断保险丝的模式。 For example, the automatic self-closing the circuit breaker or relay can be set to either preserve fuse mode may be set to blow the fuse pattern. 在保全保险丝模式里,自动继电器或自动闭合断路器切断瞬时故障的动作比保险丝快。 In the preservation fuse mode, automatic relay or circuit breaker to close automatically moves faster than transient faults fuse. 如果故障仍然存在,自动电路继电器的动作就会比保险丝的速度稍微慢一点,以便保险丝烧断并清除故障。 If the problem persists, automatic circuit relay action will be slightly slower than the speed a little fuse to the fuse blows and clear the fault. 在烧断保险丝模式中,自动继电器设定为比与继电器配套的任何保险丝动作时间都长,故障的清除应该在继电器不发生动作的情况下由保险丝的烧断来完成。 In the blown fuse mode, the automatic relay is set higher than the relay supporting any action fuse long time, the fault should be cleared in the case of the relay does not occur by a blown fuse to complete.

有一些基于微处理器的自动继电器控制器,它们能够检测故障状态,并且相应地中断对应的自动继电器。 Some automatic relay controller based on a microprocessor, which is capable of detecting a fault state, and accordingly automatically corresponding to the interrupt relay. 然而,这些以前的设计不能自适应。 However, these previous designs is not adaptive. 在这些以前的设计中,故障检测是按照一些事先编程的电流水平绝对值(亦即固定值)的函数来实现的,那样,由于正常的、日常的以及/或者季节性因素引起的渐变性电流波动不予考虑。 In these previous designs, some fault detection is programmed in advance in accordance with the absolute value of a current level (i.e., fixed value) of the function to achieve, as a result of normal, everyday, and / or seasonal factors caused by the gradient of the current fluctuations disregarded. 于是,在电流的波动并没有威胁到系统的时候供电也有可能被不必要地中断。 Thus, in the current fluctuations are not a threat to the system when the power supply is also likely to be unnecessarily interrupted. 更有甚者,基于绝对电流水平的故障检测方案不一定能检测远程故障(亦即故障发生处相对于自动继电器位置为供电线的末端)。 What is more, based on the absolute level of current fault detection scheme may not be able to detect remote fault (ie failure of the automatic relay position relative to the end of the supply line).

因此,需要提供一种能克服在先方案所存在的问题的继电器控制器。 Therefore, a need to provide a scheme that overcomes the problems of the prior relay controller. 这样,电子程序可以自适应地设定继电器以特定方式运作,比如保全保险丝模式、保险丝烧断模式、单相或是三相模式,它们以主要条件为基础,如一天里的时间点、每个星期里的天,月或载荷电流。 Thus, the electronic program may adaptively set the relay operation in a particular manner, such as preservation of the fuse pattern, fuse blowing mode, single-phase or three-phase mode, they are mainly based on conditions, such as day time point, each in the days of the week, month, or load current.

发明概要本发明涉及自动继电器响应特定保护设定组的运作。 Summary of the Invention The present invention relates to an automatic relay protection setting specific operational response group. 根据主要条件如一天里的时间点或载荷电流,自动继电器以一定的方式运作,如单相或保全保险丝模式。 According to the conditions such as the main point of time of day or the current load, the automatic operation of the relay in a certain way, such as a single-phase or protective fuse mode.

参照附图通过下面对本发明的详细说明,本发明的上述及其它方向将会更加清楚。 The following detailed description with reference to the accompanying drawings of the present invention, the above and other directions the present invention will become more apparent.

优选实施例详述本发明涉及用于自适应地控制继电器的系统和方法,以便其能响应主要条件如时间或载荷电流而按一定的方式运作。 DESCRIPTION OF PREFERRED EMBODIMENTS The present invention relates to a system and method for adaptively controlling the relay so that it can respond to conditions such as time or the main load current according to a certain manner.

输电线路和发电设备必须得到保护以防止故障及接下来的短路对它们的影响,这些故障可能会导致供电系统的瘫痪,损坏重要或昂贵的设备,以及人身伤害。 Transmission lines and power generation equipment must be protected in order to prevent the effects of faults and their subsequent short, these failures may lead to paralysis of the power supply system, important or expensive equipment damage and personal injury. 另外,经常的电力中断,可能导致那些希望得到可靠及可信的公共服务的用户们的不满。 In addition, frequent power outages, could lead to those who want to get a reliable and trusted users of public services dissatisfaction. 故障保护设施如保险丝和保护继电器的任务就是将故障线路分离或通过跳闸来形成隔离。 Fault protection facilities such as fuses and protection relays task is to form the fault line separating or isolating by tripping. 另外,在发生保护故障或其它系统故障时,电力发送操作员使用自动电力恢复元件可以自动地在线恢复电力发送系统。 Further, in the event of failure or other system failure protection, power transmitting operator using automatic power recovery device may automatically restore power line transmission system.

自动继电器设备在电力发送系统中被用来保护高压电线。 Automatic relay equipment in the power transmission system is used to protect high-voltage wire. 它们一般安在用于支撑电线的电线杆或电线塔上。 They are generally used to support security in the wire poles or wires on the tower. 然而,也有用于地下系统的情况。 However, there are conditions for the underground system. 自动继电器用来尽量减少由于输送或故障造成的电力发送中断次数。 Automatic relay to minimize the power transmission due to delivery or failure caused by interruptions.

典型地,在系统扰动过程中,就会发生电流的剧增亦即故障。 Typically, in a system disturbance process, i.e. surge occurs fault current. 通过检测电流的增加,继电器将打开并切断电流,以便保护发送系统部件及其它连在发送系统上的设备。 By increasing the sense current, the relay will open and cut off the current, in order to protect the transmission system components, and other devices connected to the transmission system. 因为许多故障状态都是暂时的,继电器设计成经过一个短时间的延迟以后再闭合,这样重新建立正常电流。 Because many of the fault condition is temporary, the relay is designed to go through a short delay after another closed, so re-establish the normal current. 比方说,在雷雨时,如果闪电击中了发送系统,送往某人家里的电力就会中断一会儿,造成照明及其它家电关掉(自动继电器打开),然后又打开(自动继电器闭合)。 For example, during a lightning storm, if lightning hit the sending system and sent someone home electricity is interrupted for a while, resulting in lighting and other appliances to turn off (auto relay open), and then turn on (automatic relay closure). 一旦自动继电器闭合,如果它仍检测到电流的增大状态,(即故障电流,而非正常负载电流),它又会重新打开。 Once the automatic relay is closed, if it still detects the current increases state (ie fault current, rather than the normal load current), it will reopen. 在自动继电器保持稳定断开状态之前,这样打开又闭合的循环过程可能会进行三次。 Before disconnecting the automatic relay stable state, so they opened the closed loop process may be carried out three times.

当自动电力恢复系统和别的保护设施如保险丝和保护继电器配合使用时,它可以以两种模式进行运作,即保全保险丝模式和烧断保险丝模式。 When the automatic power recovery system and other protective equipment such as fuses and protection relays used in conjunction with, it can operate in two modes, namely preservation mode and blown fuse fuse mode. 在保全保险丝模式里,自动电力恢复装置试图清除瞬时故障的反应速度比与之配合的保险丝的反应速度快。 In the preservation fuse mode, automatic power restoration means trying to clear the reaction speed is faster than with transient faults with the fuse reaction speed. 在自动电力恢复装置试图恢复系统时如果故障仍然存在,自动电力恢复装置的反应速度就会比保险丝的反应速度慢而让保险丝来清除故障。 Automatic power restoration means attempting If the problem persists, the automatic power restoration device response speed will be slower than the reaction rate and let the fuse fuse when restoring the system to clear the fault. 在烧断保险丝模式中,自动继电器设定为比与继电器配套的任何保险丝动作时间都长,故障的清除在继电器不发生动作的情况下由保险丝的烧断来完成。 In the blown fuse mode, the automatic relay is set higher than the relay supporting any action fuse long time, fault clearance in case the relay does not occur by the fuse blows to complete.

图1表示了一个实施本发明的系统的简化示意图。 Figure 1 shows a simplified schematic diagram of one embodiment of the system of the present invention. 自动继电器10是断开或闭合电线5(亦即处于变电所与负载之间)的开关,它由一个如电子控制器的自动继电器控制装置20所操作。 Automatically relay 10 is open or closed wire 5 (i.e. between the substation and the load is in) the switch, the operation device 20 which is controlled by an electronic controller such as automatic relay. 需要理解的是“自动继电器”这个词是自动继电器、区域性继电器、电路断路器等等的统称,它们也有可能用在本发明所包含的领域里来。 Be appreciated that the "auto relay" The word is automatically relays, regional relays, circuit breakers, etc. collectively, they may also be used in the present invention be contained inside. 电线5是三相电线。 5 is a three-phase electric wire. 自动继电器10包括三个电极15。 Automatically relay 10 includes three electrodes 15. 每个电极15与电线5中的一根与之关联的电线相连,这样它就由相应的相来供电。 Each electrode 15 and the electric wire of the electric wire 5 is connected to one associated, so that it is powered by the corresponding phase.

自动继电器10的基本组成部分是一个高速电路断电器、过载保护、跳闸逻辑以及一个带计数器的闭合逻辑单元。 Automatic relay 10 is an essential part of a high-speed circuit breaker overload trip logic and logic unit closes with a counter. 当流过自动继电器10的过载电流达到充分大时(亦即超过了预先设定的允许电流的大小),跳闸动作就会被激发,电极15的接触状态被打开,同时计数器前进一个数。 When the flow through the automatic overcurrent relay 10 reaches sufficiently large (ie more than the pre-set to allow the current size), tripping will be excited, the contact state of the electrode 15 is open, while a number of counter forward. 经过一段预设的时间延迟后,自动继电器触点将自动闭合,从而重新给电线5供电。 After a preset time delay, automatic relay contacts will automatically closed, thus re-supply to the wire 5. 如果故障仍然存在,该跳闸与重新闭合的循环过程就会重复由控制器20预先设定的次数,直到停止运作的命令被激发。 If the problem persists, the trip and reclose cycle process will be repeated by the number of controller 20 preset stop functioning until the command is fired. 如果故障是瞬时的,即故障在自动继电器10的任何一个打开状态期间被排除,则自动继电器20将在一段短时间的延迟后保持闭合状态,并且复位到初始状态以预备下一次的运作。 If the fault is transient, i.e., the fault is removed at any one of an open state 10 during the automatic relay, the relay 20 is automatically maintained in the closed state for a short time delay, and is reset to an initial state in order to prepare for the next operation.

一个用于本发明的示例性的自动继电器是VR-3S继电器,由位于北卡罗莱纳州罗利的ABB电力T&D公司制造并销售。 Exemplary automatic relay of the present invention is used for VR-3S relay, by Raleigh in North Carolina's ABB Power T & amp; D manufacturing and sales company. 采用电磁激励来打开并闭合继电器的主触点。 Electromagnetic incentive to open and close the main contacts of the relay.

自动继电器10由基于微处理器的控制器20控制,控制器中包含有软件。 Automatic relay 10 20 controlled by a microprocessor based controller, the controller contains software. 基于微处理器的控制器20有两个基本设计区。 Microprocessor-based controller 20 has two basic design area. 物理单元如集成电路、电阻、电容、显示器、开关等被成为“硬件”。 Physical means, such as integrated circuits, resistors, capacitors, displays, switches, etc. known as "hardware." 一旦制造出来以后,它们将是不可改变的。 Once created, they will not be changed. 在微型计算机里的第二个基本设计区包括计算机程序和文件。 In the microcomputer in the second basic design district, including computer programs and files. 因为这些元素易于改变,所以它们被称作“软件”。 Because these elements can be easily changed, so that they are called "software."

一台以微处理器为基础、与存储器及接口元件配套而成的微型计算机用在继电器控制器20中,用来处理适合自动继电器控制的输入信号。 A microprocessor-based, supporting memory and interface elements made of microcomputers used in the relay controller 20 for processing for automatic relay control input signal. 微处理器用来完成控制的算法和逻辑功能。 A microprocessor for performing control algorithms and logical functions. 特别地,所要求的逻辑电路与服务的功能一样,都被包含在内。 In particular, the required logic functions and services, like, are included.

一个典型的自动继电器控制系统中一般包含一个电源为自动继电器控制系统的其它元件供电,并且包括能量储存装置,当被保护线路断路时用于存储能量。 A typical automatic relay control system typically includes a power supply for other components automatic relay control system, and includes an energy storage device for storing energy when the protected circuit breaker. 当微型计算机不能实施自动继电器的跳闸动作时,一个备用的过载跳闸电路将独立于计算机之外来控制跳闸。 When the microcomputer can not implement the automatic tripping of the relay, an alternate overload tripping circuit separate from the computer to control the trip. 一个保护性的输入网保护控制器的弱电元件免受周围电力发送系统环境的影响,同时换算装置被用来提高微型计算机以及关联电路在有精度要求的输入信号大小范围内的运作精度,并使得控制可以在一个宽的输入信号范围内通过有限数量的组元来运行。 A protective element weak input protection network controller power transmission system from the effects of the surrounding environment, while conversion means is used to improve the microcomputer and associated circuits in the input signal has a precision operational accuracy size range, and such that control can be run by a limited number of component in a wide range of input signals.

寄存器或存储器30用来暂时和/或永久存储数据。 Register or memory 30 for temporarily and / or permanently store data. 举例说来,在自动继电器10中,这些数据将包含线电流的大小及命令信息如各种时间—电流特征曲线以及在后面将进一步描述的保护设定组。 For example, the relay 10 in the automatic, these data will include the size of the line current and the command information such as various time - current characteristic curve and the protective group is set will be further described later. 存储器可以是随机存储器(RAM)或只读存储器(ROM),或者其它任何型式的存储器。 The memory may be random access memory (RAM) or read only memory (ROM), or any other type of memory. ROM因易于修改而很适合电子编程,并用来存储程序信息。 ROM because it is easy to modify and suitable for electronic programming, and is used to store program information. 寄存器30可以内置到控制器20中,如图所示,或者也可以放在控制器20的外面。 Register 30 may be built into the controller 20, as shown, or may be placed outside the controller 20.

继电器控制器20的前面板可以包括一台用于显示信息的显示器。 Relay controller front panel 20 may include a display for displaying information. 键盘或其它输入设备可用来输入信息。 A keyboard or other input device may be used to input information. 指示灯用来提供状态信息如继电器断开、继电器闭合、控制被关、高于最小跳闸值、故障以及紧闭等。 LEDs to provide status information such as the relay off, the relay is closed, control is off, higher than the minimum trip value, such as failures and closed.

通过使用上述的开关和键盘,设备的操纵可以通过命令信息来进行。 Command information can be performed by using the operation switch and keyboard, the device described above. 对于一个自动继电器控制器,典型的命令信息包括相电流及地电流的第一时间电流特征,以及相电流和地电流的第二时间电流特征,其中前者通常造成继电器10更快地跳闸,而后者通常造成继电器10在故障条件下能更久地保持闭合状态。 For an automatic relay controller, typical command information includes a first time phase current and current characteristics of the ground current, and a second time current characteristic of the phase currents and ground current, of which the former usually results in faster tripping relay 10, and the latter usually cause the relay 10 under fault conditions can be maintained longer closed. 其它命令信息包括相电流和地电流的最小跳闸水平、当发生相或地故障时锁定前的重复次数以及给定的时间电流特性的使用次数,其中最小跳闸电流水平在继电器中用于启动按时间电流特征进行的计时过程。 Other command information includes a minimum trip level of phase currents and ground current, when the phase or ground fault occurs the frequency of use and the number of repetitions of the lock before the given time current characteristic, wherein the minimum current level for the trip start time in the relay current characteristics of the timing process. 其它的命令信息可能还包括清零的时间间隔长度和重新闭合时间间隔,其中清零时间间隔长度决定了在无故障条件下计数器的计数信息保留时间的长短,而重新闭合时间间隔决定了继电器保持断开状态的时间长度。 Other information may also include command clears the interval length and reclose interval, which clears the count interval determines the length of the length of time information retention in the absence of a fault condition of the counter, and re-closing time interval determines the relay remains the length of time off states. 另外的命令信息还包括高电流稳定时间特征,它使继电器10在一定大小的故障电流条件下只允许保持闭合状态一段固定的时间。 Additional command information further includes a high current settling time characteristic, it makes the relay 10 under fault current conditions of a certain size is only allowed to maintain a closed state for a fixed period of time. 这样,如果有故障发生,电线5将被断开一段很短的时间。 Thus, if a fault occurs, the wire 5 will be disconnected for a short time. 在电线5维持断开状态的给定时间段的结束处,自动继电器10会闭合电线5。 Maintaining the OFF state at the end of the wire 5 to a given period of time, the relay automatically closes the wire 10 5. 如果非正常状态仍然存在,自动继电器10将再次断开并再次闭合电线5。 If an abnormal condition still exists, the relay 10 will automatically disconnect and re-wire 5 is closed again.

本发明所述的命令信息还包括许多独立的保护设定组。 Command information of the present invention also includes a number of independent protection setting groups. 不管系统是在线还是不在线,保护设定组均可以由技术员或用户编程获得。 Whether the system is online or not online, protection setting group can be obtained by a technician or user programming. 保护设定组是用于控制一个基于一定条件的自动继电器的指令。 Protection setting group is used to control certain conditions based on automatic relay command. 一个示例性的保护设定组如图2所示。 An exemplary protection setting group shown in Figure 2. 在这里,保护设定组以一天里的时间和星期里的天为基础。 Here, the protection group is set to the time and day of week-day basis. 对某个特定的时间段或日子(亦即星期一到星期五的工作时间)采用了烧断保险丝模式,而在余下的时间段里(亦即周末或下班时间里)则采用保全保险丝模式。 For a certain period of time or day (ie Monday to Friday working hours) with a blown fuse mode, while the rest of the time period (ie weekends or after work time) is used to preserve the fuse mode. 在这种方式里,在星期一到星期五的上班时间内,供电质量根据大部分消费者的需要进行了优化,而当对供电质量要求不是那么严格的时候(周末或下班时间),运作的费用又被控制在最低的水平。 In this way, in the inner working hours Monday through Friday, according to the majority of consumer power quality needs to be optimized, and when power quality requirements are not so strict time (weekends or after hours), operational costs has been controlled to the lowest level.

另一个示例性的保护设定组如图3所示。 Another exemplary protection setting group shown in Figure 3. 在这里,根据一年中的月份,继电器被分别设定为一相(单相)模式和三相模式。 Here, according to the months of the year, relays are set at a phase (single phase) mode and three-phase mode. 从十月到三月采用的是单相模式,从四月到九月采用的是三相模式。 From October to March, using a single-phase model, from April to September is used in a three-phase model. 在这种方式里,举例说来,在农村地区,一年中的许多个月都需要灌溉,为了保护水泵的电机,这时采用三相保护模式比较合适。 In this way, the example to say, in rural areas, many months of the year require irrigation, in order to protect the pump motor, when the three-phase protection mode is appropriate. 而在余下的月份里,则采用单相保护模式比较合适,因为这时负载均为单相负载,这样采用单相保护有利于将出现故障的影响降低到最小程度。 And the rest of the month, the single-phase protection mode is used more appropriate, because then the load are single-phase load, so to minimize the use of single-phase protection facilitates the emergence of failures. 这样,时钟和日历就被用来控制继电器是采用单相保护还是三相保护,并且/或者是采用保全保险丝模式还是烧断保险丝模式。 Thus, the clock and the calendar will be used to control the relays are single-phase or three-phase protection protection, and / or the use of preservation mode or blown fuse fuse mode.

另一种示例性的保护设定组可以基于负载电流而设定。 Another exemplary protecting groups can be set based on the load current setting. 基于负载电流的时候,也可以采用不同的模式,如保全保险丝模式或烧断保险丝模式,单相或三相保护等。 When the load current based on different modes can also be used, such as the preservation of the blown fuse fuse mode or modes, single-phase or three-phase protection. 在这种方式下,根据处于激活状态的保护设定组的不同以及主要条件的不同,针对给定的故障形式将有不同的保护方式。 In this way, depending on the different active protection setting group and the main conditions for a given failure will have a different form of protection.

可以理解,许许多多的微处理器都可以用来实现上述同样的作用。 Will be appreciated, many microprocessor can be used to achieve the same effect as described above. 每个制造厂家均要求他们设备的特性作为自动继电器控制器20的微型计算机的一部分能满足要求,在这里,非常详细地去描述各功能性控制以及全面而充分地描述各替用设备的使用情况显然是不可能的。 Each manufacturer require their device characteristics relay controller automatically as part of the microcomputer 20 can meet the requirements, where, to a very detailed description of the functions of control and a comprehensive and full description of the various alternate use of equipment It is clearly impossible. 通过阅读另一设备的厂家提供的技术说明书,本领域技术人员很轻易地就能放大和修改已知的说明以适应别的厂家制造的设备。 By reading the other device manufacturers to provide technical specifications, those skilled can easily enlarge and modify the instructions to fit the device known other manufacturers manufacture. 而且,如果想试着去描述软件中的每一个细微的细节的话,可能会陷入极端的迷茫,因为本领域技术人员很容易地就能理清其中的构架来,因此这里只描述了那些更一般化的软件模块和程序。 And, if you want to try to describe the software in every nuance of detail, it may fall into extreme confusion, because the skilled person can easily sort out which of the framework to, so here describes only those with more general of software modules and procedures.

一种示例性的控制元件是PCD2000电力控制装置,由位于北卡罗莱纳州罗利的ABB电力T&D公司制造并销售。 An exemplary control element is PCD2000 power control unit, located in the Raleigh, North Carolina, ABB Power T & amp; D company manufactured and sold. 控制设备可以提供用于远程通信的接口,用于与使用MODBUS RTU MODBUS ASCII以及DNP3.0协议的SCADA系统相联。 Control devices can provide interfaces for remote communication for using MODBUS RTU MODBUS ASCII and DNP3.0 protocols associated SCADA system. 控制器可以使用别的协议来编程。 The controller can be programmed using a different protocol. 还有可以用来与外界进行联系的接口如无线通信、调制解调器以及直接光纤通信。 There can be used to interface with the outside world, such as a wireless communication link, fiber optic modems, and direct communication.

图4是本发明所述的一种操作方法的流程图。 Figure 4 is a flow diagram of a method of operation of the present invention. 在电力输送时,自动继电器10监控电线5。 When power transmission, automatic monitoring relay 10 5 wire. 在第100步,设定组被决定、选择或确定下来。 In step 100, the group decided to set, select or finalized. 设定组可以从寄存区30处(亦即一个内置或捆绑于继电器控制器20上的一个存储器)得到。 You can set the group (that is a built-in or bundled in a memory 20 on the relay controller) obtained from 30 storage area. 许多设定组(相关或不相关)都可以存储于寄存区30处,当系统在线或不在线的时候,技术员或用户均可以从中选择合适的设定组。 Many setting group (related or unrelated) can be stored in the storage area 30, when the system is online or not online, technicians or users can choose the appropriate setting group.

当设定组确定以后,与设定组相关的特征的当前或主要的状态在110步确定。 When the group is set to determine the current state or the main features associated with the set group is determined in step 110. 例如,如果图2中设定组处于激活状态,则一天中的时间及星期中的天将被确定,因为,保全保险丝模式与烧断保险丝模式的选择取决于这两个参数。 For example, if 2 is set in the group is active, the time of day and day of the week will be determined, because the preservation mode and select the fuse blown fuse mode depends on these two parameters. 作为另一个例子,如果图3中的设定组处于激活状态,一年中的月份就会被确定,因为单相还是三相操作的确定是对一年中特定月份的反应。 As another example, if in Figure 3 is set group is active, the month of the year will be determined, because the single-phase or three-phase operation determines that a particular month of the year of the reaction.

在第120步中,合适的继电器行为由在主要条件基础上建立起来的保护设定组确定。 In step 120, the appropriate relay behavior is determined by the set up of the main conditions set on the basis of the protection group. 这是通过将第110步中的主要条件与第100步中的保护设定组的条件条目进行比较而得到的,相匹配的条目在第130步将被用到。 This is accomplished by the conditions in the entry step 110 in step 100 and the main conditions of the protection set group obtained by comparing the phase matching entry in step 130 will be used. 这样,例如,如果图2中的设定组处于激活状态,而时间为星期三下午1点,那么根据保护设定组条目,将应用烧断保险丝模式。 Thus, for example, if the setting group in Figure 2 is active, while the time is 13:00 on Wednesday, then according to the protection setting group entries, will blow the fuse mode applications.

在第140步,当前或主要条件被连续监控,以决定继电器的行为是否需要改变,如第150步所决定的一样。 In step 140, the current or the main conditions are continuously monitored to determine whether the behavior of the relay needs to be changed, the same as step 150 of the decision. 如果行为应该改变,则新的行为就会被确定并应用到第130步的过程中。 If the behavior should be changed, the new behavior will be determined and applied to the process of step 130. 如果行为不应该改变,则监控过程将继续,象140步的过程一样。 If the behavior should not be changed, the monitoring process will continue, the same as the 140-step process. 通过技术员或用户的编程,主要条件被按照事先规定好的间隔(如时间)或其它事件发生方式而监控着。 By technician or user programming, the main condition is good according to the stipulated intervals (such as time), or other events monitored manner.

这样,例如,如果图2中的设定组处于激活状态,当时间从星期三下午5:00变成下午5:01时,模式就从烧断保险丝模式变成保全保险丝模式。 Thus, for example, if the setting group in Figure 2 is active, when the time becomes 5:00 pm from 5:01 pm Wednesday, the mode becomes preservation mode from the blown fuse fuse mode. 保全保险丝模式会一直用到星期四上午8:00,那时,又会变成烧断保险丝模式。 Fuse preservation mode has been used at 8:00 am Thursday, then, will become a blown fuse mode.

在不脱离本发明的实质和范围的情况下,本发明既可以通过合适的计算机软件,也可以通过合适的硬件,或者通过合适的软件与硬件的组合来实施。 Without departing from the spirit and scope of the present invention, the present invention either through appropriate computer software, or by the appropriate hardware, or by a suitable combination of software and hardware to implement. 关于这些硬件和/或软件的更进一步的细节对相关的普通大众而言都是显而易见的。 Details of these hardware and / or software of the associated further be apparent to the general population. 因此,在这里就这些硬件和/或软件做更进一步的描述是没有必要的。 So, here is the hardware and / or software to do further description is not necessary.

尽管这里参照特定的具体实施例用图示及描述的方式对本发明进行了说明,本发明仍不只限于所述的细节。 Although specific reference herein to specific embodiments shown and described by way of use of the present invention has been described, the present invention is still not limited to the details. 在权利要求书的范围内可以作出各种细节上的修改,而不脱离本发明的范围。 Within the scope of the claims that various changes in detail may be made without departing from the scope of the invention.
