| Abstract: | A real-time and off-line substation fault analysis system is proposed based on the integration of fault records and protection information,and the corresponding software is developed.The format conversion between fault records and protection information is based on COMTRADE protocol.The technologies of analog low-pass filter and digital filter and the screening and compression methods of FFT and wavelet transformation are applied to preprocess the fault records for the integration of fault records and prote... |
