Abstract
The disclosure describes implementations of methods, systems and apparatuses that are configured to facilitate normal operating characteristics for a wind turbine during normal operation, as well as during voltage irregularities. In an implementation, a turbine controller coordinates operating primary turbine systems and ancillary turbine systems during normal operation and during voltage irregularities. During normal operation, the turbine controller coordinates powering both primary and ancillary turbine systems through a power supply. During a detected voltage event, ancillary turbine systems may be transitioned to a having an uninterruptible power supply power these systems. However, the turbine controller coordinates maintaining the power supply as the sole powering device for primary turbine systems despite a voltage irregularity. In some implementations, when the power supply reaches a critical level during a voltage irregularity, a system fault flag is generated and the turbine blades may be driven into a full feather operational position.
