Hydro-generator rotor winding turn-to-turn short circuit fault detection method and system

The invention relates to a hydro-generator rotor winding turn-to-turn short circuit fault detection system and a hydro-generator rotor winding turn-to-turn short circuit fault detection method. The system comprises a data collector connected with a hydro-generator set stability monitoring and analyzing system; and the processor performs hydro-generator rotor winding turn-to-turn short circuit fault detection and judges whether the target magnetic pole winding turn-to-turn short circuit occurs or not. The method does not need to stop the generator set, can timely find the turn-to-turn short circuit fault of the rotor winding and accurately position the fault magnetic pole position, is easy to popularize and apply, and is of great significance to safe and stable operation of the water-turbine generator set. 本发明涉及一种水轮发电机转子绕组匝间短路故障检测系统和方法，该系统包括与水轮发电机组稳定性监测分析系统连接的数据采集器；处理器，处理器进行水轮发电机转子绕组匝间短路故障检测，判断目标磁极绕组匝间是否短路。本发明不需要机组停机，能够及时发现转子绕组匝间短路故障，准确定位故障磁极位置，易于推广应用，对水轮发电机组的安全稳定运行具有重要意义。
