摘　　要：针对发电机转子过电压保护试验是否要退出RC缓冲回路的问题,进行了RC回路投入与解开两种情况下的试验,并在仿真平台上搭建同样参数的模型进行仿真试验。结果表明,仿真试验结果与现场试验结果一致。在此基础上,进一步分析了RC回路与试验电源频率对转子过电压试验的影响。试验及仿真表明,转子过电压保护试验时应将RC缓冲回路解开。本文的试验分析及其结论可为同类型转子过电压保护装置的试验提供参考。Aiming at the question of whether to exit the RC buffer circuit in the generator rotor overvoltage protection test,the two cases of RC circuit input and unlocking are tested,and a model with the same parameters is built on the simulation platform to carry out the simulation test.The results show that the simulation test results are consistent with the field test results.On this basis,the influence of the RC circuit and the test power frequency on the rotor overvoltage test is further analyzed.Tests and simulations show that the RC snubber circuit should be disengaged during the rotor overvoltage protection test.The test analysis and conclusions in this paper can provide reference for the test of the same type of rotor overvoltage protection device.
