摘要 分布式控制具有结构简单、易于维护、可扩展性强等优点,目前是大功率电力电子设备领域的研究热点。介绍一种适用于高电压大功率链式静止无功补偿器(STATCOM)系统的分布式控制设计方案,分析对于分布式控制系统的安全和稳定运行十分重要的同步控制、故障响应等问题,并就分布式系统的直流母线电压平衡控制展开讨论。通过6k V/1MV·A链式STATCOM的并网实验,验证分布式控制系统的有效性、可扩展性以及可靠性。 Distributed control scheme is the hotspot in the field of high power electronic system because of its simple structure,low maintenance and high scalability.This paper proposes a distributed control scheme applied in the cascaded H-bridge(CHB)multilevel static synchronous compensator(STATCOM).As the important issues of safe and stable operation,synchronization and fault protection of distributed control system are discussed,as well as the DC-link balancing control method.The experiments based on6kV/1MV·A CHB STATCOM prototype verify the effectiveness,flexibility and reliability of the proposed distributed control scheme.
