摘要(Abstract):
RSO法是检测发电机转子匝间故障的重要方法之一。通过对RSO法原理的分析,提出RSO法在发电机转子绕组一点接地故障检测中同样适用的观点,经过模拟试验区分了转子匝间短路故障和接地短路故障下RSO法得到不同的试验结果,并根据试验结果辅助定位了某发电机转子接地故障的位置,证明了RSO法在检测发电机转子绕组一点接地故障中的适用性。
Recurrent surge oscillograph(RSO) is one of the important methods to detect interturn faults of generator rotor. According to the theoretic analysis of RSO, the paper suggests that RSO is applicable to detect one-point earth fault of generator rotor winding. Through simulation test different test results of interturn short circuit fault and earthing short circuit are distinguishes via RSO. According to the test results, earth fault of a generator rotor is located, which demonstrates that RSO is applicable to detect one-point earth fault of generator rotor winding.
