高容量SVC和STATCOM在实际电网中的比较.pdf

2010 International Conference on Intelligent Computation Technology and Automation Comparison of high capacity SVC and STATCOM in real power grid Ding Lijie, Liu Yang Miao Yiqun Test and research institute College of Electrical Engineering Sichuan electric power Zhejiang University Chendu, China Hangzhou, China ding_lijie@163.com jlld@ Abstract—Both SVC (Static Var Compensator) and costly and more complicated. In reality, SVC is used more STATCOM (Static Synchronous Compensator) are important often than STATCOM as reactive compensation equipment equipment of reactive compensation, which are compared in in transmission system of power grid, and the ratio is about voltage supporting, improving the transient stability and 6.7:1. transmission limit, and damping low frequency oscillation. This paper is organized as follows: Section II compares Simulation results are presented as high capacity static var the voltage supporting, transient stability and transmission system for SVC or STATCOM is placed on transmission path limit, and damping low frequency oscillation effect of power system. Firstly, single SVC and STATCOM are limited in voltage supporting aft
