摘要(Abstract)：

电压质量调节器(voltage quality conditioner,VQC)常规控制中,其串联变流器主要输出有功功率处理电压暂降问题,通常处于待机状态,未得到充分利用。文章针对所设计的VQC结构,提出基于有功环流的VQC功率流协调控制策略,利用串联变流器输出无功功率,分担并联变流器的无功补偿功能。通过分析系统中功率流和有功环流的变化,得到串并联变流器的无功分配策略、串联变流器的复合控制策略和储能单元的补偿策略,实现了VQC各单元的协调控制。仿真与实验结果验证了所提控制策略的有效性与可行性。

关键词(KeyWords)： 电压质量调节器;协调控制;功率分配;无功补偿;电压暂降/骤升;超电容储能
