Unbalanced Control Scheme for Cascade STATCOM Based on SBPF

doi:10.11930/j.issn.1004-9649.2013.8.138.4

Abstract

Abstract: Under unbalanced system voltages, the operation of cascade static synchronous compensator(STATCOM) shall be maintained in stable state so as to make contribution to power factor correction and voltage stability. However, the performance of a cascade STATCOM with traditional decoupling power control will drastically deteriorate under unbalanced voltages. Therefore, a novel control scheme for star-connected cascade STATCOM operating under voltage unbalance is proposed, in which the selective band pass filter (SBPF) is combined with decoupling power control to realize unbalanced control and rapid response characteristic of STATCOM. Simulation results show that the control scheme can significantly improve the operation stability and compensation effect of the cascade STATCOM under unbalanced voltages compared with the traditional decoupling power control algorithm.

Key words: cascade STATCOM, selective band pass filter (SBPF), decoupling power control, voltage unbalance
