ABSTRACT

In order to ensure the stability of power grid, 0.4kV/10kV power transformer PD on-line monitoring system is studied in this paper. With the help of pulse current detection method, the PD propagation characteristics can be precisely located by the power spectrum density (PSD). In order to have a good weight distribution of PSO and the statistical analysis problem, PSD-PSO algorithm is introduced in this paper. And the comprehensive fault decision based on PSD- PSO algorithm is studied in this paper. At last the simulation results show that the proposed method can improve the accuracy and the real- time performance of fault diagnosis via power transformer.
