摘要
Abstract
The improved p-q detection method of compensation current which is suitable for unbalanced grid voltage and distortion and its application in STATCOM is presented. This detection method based on positive sequence detector which can accurately detect the fundamental positive sequence voltage, it also can avoid the unbalanced voltage participate in the p-q operation, so the compensation current component can be accurately detected. In addition, the main circuit topology structure of STATCOM, the pulse width modulation and direct current control strategy are also showed in this paper. Finally, the STATCOM device based on improved p-q detection method can quickly and accurately compensate current for the grid, which is verified by the analysis of simulation experiment.关键词
