DETECTING ELECTRICAL FAILURES IN A WIND TURBINE GENERATOR CONTROL SYSTEM

A method of detecting electrical failures in a wind turbine generator control system is described. The method comprises sending a test pulse through a signal path within the control system and detecting the test pulse once it has passed through the signal path, measuring a current through the signal...

Beschreibung
Zusammenfassung:	A method of detecting electrical failures in a wind turbine generator control system is described. The method comprises sending a test pulse through a signal path within the control system and detecting the test pulse once it has passed through the signal path, measuring a current through the signal path, and determining an input status and/or an output status of the signal path. Then, the natureof the electrical failure is identified based on a combination of the detected test pulse, the measured current and the determined input status and/or output status of the signal path. 描述了一种检测风力涡轮发电机控制系统中的电气故障的方法。该方法包括：通过所述控制系统内的信号路径发送测试脉冲，并且在所述测试脉冲通过所述信号路径后检测所述测试脉冲；测量通过所述信号路径的电流；以及确定所述信号路径的输入状态和/或输出状态。然后，基于检测的测试脉冲、测量的电流以及确定的信号路径的输入状态和/或输出状态的组合来识别所述电气故障的性质。
