Abstract
垂直的和水平的风切变、横偏和/或湍流共同作用产生穿过风力涡轮机转子的不对称载荷。合成载荷在叶片中产生弯矩,该弯矩作用到毂并随后作用在主轴上。结果是,主轴可从其静止位置径向位移。利用两个或多个传感器可测量径向位移量。来自传感器的输出信号被用来确定合成转子载荷的大小和/或方向。该信息被用来使得叶片节距发生变化或进行具有相似系统效果的其他动作,以减小不对称载荷并从而减小了各种涡轮部件上的疲劳和载荷。
Description
技术领域
本发明涉及风力涡轮机。更具体地,本发明涉及基于轴的径向位移进行的载荷控制。
背景技术
实用级的风力涡轮机(即设计用来为公共电网提供电力的风力涡轮机)可以具有大的转子(例如,30米或更大的直径)。由于垂直或水平风切变、横偏和湍流,产生横跨这些转子的不对称载荷。这些不对称载荷在转子叶片和其他风力涡轮机部件上产生过度载荷和一定数量的疲劳循环。
已经开发了各种技术来减小由转子的不对称载荷导致的疲劳。例如,在1997年10月P.Caselitz等人在爱尔兰都柏林堡(Dublin Castle,Ireland)举办的欧洲风能会议上发表的“通过先进控制方法减少风能转换器上的疲劳载荷(Reduction of Fatigue Loads on Wind Energy Converters by Advanced ControlMethods)”中公开了塔振动的主动阻尼技术。然而,这里公开的技术基于塔的倾斜和摇摆,其仅提供了关于各个风力涡轮机部件上的载荷的一般信息。
基于专利合作条约(PCT)在2001年5月10日公布的、题为“风力涡轮机运行的控制方法和使用所述方法的风力涡轮机(METHOD OFCONTROLLING THE OPERATION OF A WIND TURBINE AND WINDTURBINE FOR USE IN SAID METHOD)”(公开号WO 10/33075,PCT申请号PCT/DK99/00595)的国际申请中公开了一种另外的技术。该PCT申请公开了一种涡轮控制器,该控制器基于作用在叶片上的机械载荷控制风力涡轮机叶片的节距。然而,所述PCT申请中的控制系统很复杂,因为必须不断地评估多个叶片传感器的输出。

附图说明
本发明通过示例的方式示出,而不是以限制的方式示出,在附图中相同的附图标记指代相似的部件。
图1是风力涡轮机部件的一个实施例。
具体实施方式
描述基于轴的径向位移的风力涡轮机载荷的控制方法和设备。在以下的描述中,为了解释的目的,阐述了多个特定的细节以彻底理解本发明。然而,对本领域技术人员显而易见的是,没有这些特定细节也可以实施本发明。在其他情形中,结构和装置以框图形式示出以避免模糊本发明。
垂直和水平风切变、横偏和/或湍流共同作用而产生横跨风力涡轮机转子的不对称载荷。所形成的载荷在叶片上产生弯矩,该弯矩作用到毂并随后作用在低速轴上。结果,主轴从其静止位置产生位移。虽然轴的径向位移可利用一个传感器进行测量,但需要两个或多个大致正交定位的传感器将径向位移解析为控制目的所需的形式。然后,来自传感器的输出信号可被用来确定所产生的转子载荷的大小和/或方向,并通过例如控制叶片节距来调节该载荷或载荷的不对称性。
减小载荷并因此减小各涡轮部件上的载荷和疲劳所需的叶片节距改变可根据传感器产生的输出信号确定。派克斯DQ变换(Parks DQtransformation)、偏差估计方法计算和/或其他控制技术可用来计算每个转子叶片的节距增量以减小总的和/或不对称的转子载荷。可以减小转子叶片和其他涡轮机部件的疲劳和过度载荷。
主轴径向位移的确定可利用传感器得到,所述传感器利用基于声、光、磁、电容或感应场效应的传感器技术测量轴的位移或应变。在一个实施例中,使用接近传感器测量主轴径向位移。在一个实施例中,使用最少两个传感器测量主轴径向位移。如下文中更详细描述的那样,也可以使用额外的和/或不同的传感器。
图1是风力涡轮机部件的一个实施例。除了毂110之外,图1的各部件容纳在塔190上的机舱185中。塔190的高度可基于现有技术中公知的因素和条件选择。在一个实施例中,使用了多个微控制器(例如,在控制板195中)对整个系统进行监测和控制,包括节距和速度调节、高速轴和偏航制动施加(yaw brake application)、偏航(yaw)和泵用马达应用以及故障监测。也可以使用其它分散式或集中式控制结构。
在一个实施例中,控制系统将控制信号提供给可变叶片节距控制器120以控制借助风驱动毂110的叶片(图1中未示出)的节距。在一个实施例中,毂110装设有三个叶片;然而,可使用任何数量的叶片。在一个实施例中,各叶片的节距可通过叶片节距控制器120独立控制。毂110和涡轮机叶片结合以形成风力涡轮机转子。
风力涡轮机的传动系统包括连接到毂110和齿轮箱160的转子轴175,在一个实施例中,使用双路构造(dual path geometry)驱动封装在齿轮箱中的高速轴。高速轴用来驱动发电机150。在一个实施例中,转子扭矩通过联轴器165传递。任何类型的发电机,例如线绕感应发电机可用于图1的风力涡轮机中。
偏航驱动器170和偏航平台180为风力涡轮机提供了偏航定向系统。在一个实施例中,该偏航系统基于从安装在机舱上的风向标155接收的信息由控制系统电操作和控制。在一个实施例中,偏航系统安装在设置在塔190顶部的凸缘上。
如下文更详细的描述,设置有一个或多个接近传感器以探测主轴175从预定静止位置的偏移(deflection)。利用来自传感器的数据,涡轮机控制器(图1中未示出)可确定导致由传感器探测的偏移的叶片上的载荷。利用该信息,涡轮机控制器可使叶片节距改变以减小叶片上的载荷或减小载荷的不对称性(即,使得转子上的载荷更对称)。
下面说明基于传感器测量值控制叶片节距的系统的一个实施例。(各)接近传感器(proximity sensor)响应于风力涡轮机部件例如主轴的位移产生信号。涡轮机控制器连接到(各)传感器以接收(各)传感器产生的信号。涡轮机控制器分析该信号以确定导致偏移的力。
在一个实施例中,涡轮机控制器包括从(各)传感器接收输出信号(模拟信号或数字信号)的处理器。该处理器可以例如是执行指令的通用处理器、硬连线控制电路(a hardwired control circuit)或通用处理器和硬连线电路的组合。响应于从(各)传感器接收的信号,涡轮机控制器产生传送到叶片节距控制器的控制信号。
叶片节距控制器连接到一个或多个控制风力涡轮机叶片节距的叶片旋转驱动器。通过改变叶片的节距,作用在涡轮机上的载荷的大小和/或持续时间可被减小,从而改善风力涡轮机的整体性能。
横跨风力涡轮机转子的不对称载荷会由于垂直和水平风切变、横偏、湍流等而产生。横跨转子的不对称载荷呈现为主轴的偏移或应变。因此,诸如径向位移的轴位移的测量值可用来计算不对称载荷的大小。
所计算的大小可被用来确定相应于风力涡轮机每个转子叶片的叶片节距指令以减小作用在转子轴上并传递到其他涡轮机部件的不对称载荷。坐标变换、偏差估计方法和/或其他控制技术可用来计算相应于各转子叶片的倾斜角(pitch angle)以减小总的不对称转子载荷。可以减小转子叶片和其他涡轮机部件的疲劳和过度载荷。
在一个实施例中,轴的径向位移通过分析来自传感器的信号进行确定,所述传感器基于声、光、磁、涡电流、电容或感应场或其他技术利用传感器技术测量轴的位移。在一个实施例中,使用接近传感器测量相对于低偏移参考框架如主框架或低速轴主轴承壳体的位移。
最少两个传感器被用来测量轴的径向位移;然而,为了冗余信息、传感器诊断目的或其他原因,可使用多于两个的传感器。包括四个传感器的实施例,每个传感器绕着主轴表面的圆周以90度间隔设置。包括绕着主轴以90间隔成对设置的四个传感器的实施例。还包括绕着主轴以90间隔成对设置的四个传感器的备选实施例。在一个实施例中,传感器尽可能远离齿轮箱设置位。在备选实施例中,传感器大致居中地设置在齿轮箱160和主轴承125之间。
下面说明涡轮机控制器的一个实施例。涡轮机控制器包括总线或其他交换信息的通信装置,以及连接到总线以处理信息的处理器。虽然示出的涡轮机控制器具有单个处理器,但涡轮机控制器可包括多个处理器和/或协处理器(co-processor)。涡轮机控制器还包括连接于总线以存储由处理器执行的信息和指令的随机存取存储器(RAM)或其他动态存储装置(称为存储器)。存储器也可用来在由处理器执行指令期间储存临时变量或其他中间信息。
涡轮机控制器也可包括连接于总线、以存储用于处理器的静态信息和指令的只读存储器(ROM)和/或其他静态存储装置。数据存储装置连接到总线以存储信息和指令。(各)输入/输出装置可包括本领域公知的任何装置以将输入数据提供给涡轮机控制器和/或接收来自涡轮机控制器的输出数据。
指令经由远程连接从存储装置如磁盘、只读存储器(ROM)集成电路、CD-ROM、DVD提供给存储器,所述远程连接既可以是有线的也可以是无线的,提供通往一种或多种电子存取介质等的通路。在其他实施例中,硬连线电路可用来代替软件指令或与其结合。因此,指令序列的执行不限于硬件电路和软件指令的任何特定组合。
传感器接口是一种允许涡轮机控制器与风力涡轮机内的一个或多个传感器通信的接口。例如,传感器接口可进行连接以接收来自如上所述探测风力涡轮机部件的偏移的一个或多个传感器的输出信号。传感器接口可以是例如模拟-数字转换器,该转换器将传感器产生的模拟电压信号转换为可被(各)处理器使用的多位数字信号。
然后,(各)处理器可分析这些数据并通过(各)输入/输出装置将数据传输到叶片节距控制器,以使叶片节距控制器改变风力涡轮机的一个或多个叶片的节距。(各)处理器也可以响应来自传感器的信号采取其他行动。例如,(各)处理器可施加经由叶片节距实现的机械或气动制动以停止或减慢毂或旋转轴的旋转。
下面说明响应于轴的径向位移控制风力涡轮机叶片节距的一个实施例。首先,接收来自一个或多个传感器的信号。接收信号的部件(例如处理器、模拟-数字转换器)与传感器连接并在需要时将信号转换为可用的格式。
随后,响应来自传感器的信号,控制电路(例如处理器、硬连线控制电路)利用来自传感器的信号确定一个或多个风力涡轮机部件上的载荷。控制电路可利用本领域公知的任何数学方程在输入数据(例如位移的大小)和相关的载荷数据(例如施加在风力涡轮机叶片上的力)之间进行转换。转子叶片上的、产生所述位移的载荷和载荷的任何不对称性也可以通过控制电路进行确定。
随后,控制电路确定对于载荷条件的响应。例如,响应于涡轮机叶片上增加的载荷,控制电路可确定所述响应应该是改变风力涡轮机的一个或多个叶片的节距。作为另一实例,控制电路可确定所述响应应该是施加制动以停止或减慢毂的旋转。作为另一实例,控制电路可确定所述响应应该是施加某一其他动作,例如诱发补偿性的偏航调节。
随后,控制电路产生启动选定响应的信号。例如,控制电路可产生形式例如为经由各个控制线路传输的数据包或一组控制信号的信号,以使叶片节距控制器改变一个或多个叶片的节距。随后,如果选定的响应未能使得风力涡轮机在可接受的操作范围内操作,该处理过程可按需要重复或甚至停止,致使节距控制没有得到所述的低速轴反馈节距控制算法的好处。
说明书中提及的“一个实施例”或“实施例”意指结合该实施例描述的特定的特征、结构或特性被包括在本发明的至少一个实施例中。在说明书各处出现的词组“在一个实施例中”不一定总是指相同的实施例。
在上述说明书中,已经参考其特定实施例描述了本发明。然而,显而易见的是可以在不脱离本发明更广泛的实质和范围的情况下对其进行各种修改和改变。因此,本说明书和附图被认为是示例性的而不是限制性的。
