摘要(Abstract)：

直流潮流控制设备能够有效提升环网式直流电网的潮流控制自由度,解决部分线路潮流不可控问题。首先对现有3类直流潮流控制设备进行了简略分析,指出其在实际应用场合的局限性。然后,对电流潮流控制器(current flow controller,CFC)的工作原理和运行特性进行了分析,指出其具有9种运行状态。以其中一种状态为例,设计了CFC的控制策略,研究了各状态量之间的关系。最后,给出了CFC在环网式五端直流电网中的应用实例,通过PSCAD/EMTDC下3种仿真情景的研究,验证了CFC对直流潮流调节的可行性,并进一步表明,与现有直流潮流控制设备相比,CFC具有成本投入少,运行损耗小等优势。

关键词(KeyWords)： 环网式直流电网;直流潮流控制;电流潮流控制器;损耗;经济性
