- Abstract:
-
The partial discharge detection signal of power transformer is analyzed to detect various disturbances at the site, and the partial discharge detection signal for computer simulation and simulation of field interference is designed, and on the basis of the introduction of wavelet and wavelet packet algorithm, the wavelet packet decomposition and reconstruction algorithm is applied to the detection problem of transformer partial discharge signal under strong carrier and radio interference, and the computer simulation of wavelet packet decomposition and reconstruction is carried out on the simulated partial discharge signal. The simulation results show that the wavelet packet decomposition and reconstruction algorithm can detect the partial discharge signal from the strong carrier and radio interference and has good performance.
