| Abstract: | The operation principle of STATCOM and the principle of sampling time staggered-SVM （STS- SVM） were analyzed and introduced. Its realizing method in cascade H-bridge STATCOM was presented. The simulation model and experiment of STATCOM system were established under static compensation and dynamic compensation. The results show that the cascade H-bridge multilevel STATCOM can fast and effectively compensate the reactive power and suppress the harmonic current, the system has a perfect performance on dynamic characteristics and robustness. |
