静止同步补偿器不平衡控制的伴生谐波与对策
Associated Harmonics with the Unbalance Control in STATCOM and Its Countermeasure
摘要
Abstract
STATCOM adopted to control over unbalanced voltage and currents at the point of common coupling in power ditribution system is a kind of effective method to improve electric power qualities in power grid. The switching function model is used in this paper to analyse the STATCOM output current waveshape distorttion mechanism caused by modulation coupling between DC and AC sides in unblanced control, whereby an improved swithch function is presendted to cut off the coupling passageway from DC side to AC side so as to eliminate the influence of unbalanced control over the AC side current of STATCOM. With three-phase loading unblance control as an example, the simulation model of three-phase unbalance control system is established to test the correctness of theoretical analysis.关键词
