摘要
Abstract
Traditional passive islanding detection method has a large blind area, thus a new passive islanding detection method is proposed. The method uses the Hilbert - Huang Transform (HHT) to detect the frequency spectrum characteristics of the voltage (Ppcc) waveform at the point of common coupling (PCC) and the time when singularity occurs. When the singularity appears, the BP network is started after a delay, which by identifying the current frequency spectrum category of Fpcc determines whether there is an island phenomenon. In consideration of the effects of load changes, voltage fluctuations and other disturbances on the island testing, simulation experiments are conducted. The results show that this method has small blind area, and the detection time meets the specified value of IEEE Std. 2000-929 standards, with high accuracy and reliability.关键词
