基于小波分析与SVM的孤岛与扰动辨识研究
Identification Research of the Island and the Disturbance Based on Wavelet Analysis and SVM
Due to disturbance, islanding can’t be accurately detected, so this paper proposes a new disturbance islanding and disturbance identification method without active power disturbance. When the voltage fluctuation is detected at the point of common coupling, a periodic reactive current as a disturbance component is applied. The characteristic component of reactive power through local load is extracted by wavelet analysis, is identify between islanding and disturbance using SVM. The simulation results show that the method can accurately identify the islanding and grid disturbance.
