摘　　要：针对具有储能功能的无功补偿器BS-STATCOM(STATCOM with battery energy storge system),讨论了其拓扑演化过程与系统集成特点,研究了其有功无功耦合问题,并分析了采用类STATCOM控制策略存在的问题。提出一种基于bangbang原理的新型控制策略,并对比分析,结果表明所提出的基于bangbang原理的新型控制策略能够有效地改善功率控制性能,扩大有功输出的范围。基于MATALB/Simulink构建了2 Mvar的BS-STATCOM仿真分析平台,分别对两种控制策略进行了仿真分析,验证了理论分析的正确性。A comprehensive research on STATCOM with battery energy storage system（BS-STATCOM） is conducted in this paper. First, the evolution process of the topology and the characteristics of system integration are discussed. On this basis, the coupling between active and reactive powers is studied, and the problem when adopting the quasiSTATCOM control strategy is also analyzed. Then, a novel control strategy based on the bangbang principle is proposed.Comparison results show that the proposed novel control strategy can effectively improve the power control performance and enlarge the range of output active power. Finally, a 2 Mvar simulation platform of BS-STATCOM is constructed based on MATALB/Simulink, and the above two control strategies are simulated and analyzed, respectively. Simulation results verify the correctness of the theoretical analysis.
