摘要
Abstract
In order to explore and popularize the application of Recurrent Surge Oscillograph(RSO)method in detecting inter-turn short circuit of large salient-pole rotor windings,the control variable method is adopted according to the application and experience in the hidden-pole generator,and a simulation test is carried out in a large hydro-generator to study the response and detection under the action of excitation signals with different frequencies,waveforms,amplitudes and pulse widths.It is concluded that,the attenuation of square wave is smaller than that of sawtooth wave,the attenuation in signal propagation increases with the increase of frequency,it is unfavorable to fault diagnosis when the pulse width is too large,and increasing the amplitude of the excitation signal is beneficial to improve the sensitivity of fault detection.关键词
