摘　　要：以基于分布式同步串联补偿的分布式柔性交流输电系统为研究对象,以分布式柔性交流输电系统的补偿效率为研究问题,深入研究了分布式柔性交流输电系统的集群控制策略。根据分布式同步串联补偿器的损耗分析和补偿能力特性,定义了分布式柔性交流输电系统的补偿效率。讨论了分布式柔性交流输电系统的集群控制策略补偿,并提出了一种高效的集群控制策略,使得分布式柔性交流输电系统可以在整个运行范围内都保持极高的补偿效率。The cluster control strategy of the advanced low-investment power flow control system distributed flexible AC transmission system(D-FACTS),which was based on a large amount of distributed synchronous series compensators was discussed comprehensively from the view point of compensation efficiency.Based on the loss analysis and compensation capability characteristics of distributed synchronous series compensator unit,which was the atomic unit of D-FACTS,the compensation efficiency of the D-FACTS was defined.The cluster control strategy of D-FACTS was discussed with the consideration of optimized compensation efficiency.Consequently,a novel cluster control strategy was proposed to guarantee extremely high efficiency of D-FACTS within all operation range.
