The Propagation Characteristics of Partial Discharge Signals in Enclose Busbar

Article Preview

Abstract:

Time-domain waveform of partial discharge (PD) signals of generator stator is distorted in enclosed busbar by the influence of distribution parameters of electrical equipment and different connection structure of enclose busbar. To research propagation characteristics of PD signals, a model of enclosed busbar between generator busbar exports and main transformer is established by using EMTP-ATP software. To analyze the propagation characteristics of time-domain waveform, voltage and current wave of PD signals are simulated. Voltage wave and current wave will be carried out fast fourier transform (FFT) algorithm by the use of MATLAB, frequency-domain characteristics are analyzed. It follows that the influence of time-domain waveform and frequency-domain characteristics of PD signals. The basic theories is provided for the location of PD signal monitoring sensor.
