摘要(Abstract)：

直流潮流控制器可显著增强直流电网运行灵活性和线路潮流的可控性。主要采用灵敏度分析方法研究潮流控制器对直流电网运行网损的影响。指出通过引入潮流控制器可以降低原直流输电系统运行网损,此外,潮流控制器不同安装位置可影响到运行网损的减少量大小,依据网损对潮流控制器工作变比的灵敏度公式,可求得运行网损最小时对应的潮流控制器工作变比。以三端环网式直流输电系统为例,通过仿真验证了理论分析的正确性。在上述研究工作基础上,还提出了一种新的直流潮流控制器的工作模式:在没有潮流调节任务时,通过合理配置潮流控制器以减小系统运行网损,从而使得直流潮流控制器不但可以起到控制线路直流潮流的作用,还可通过合理配置其工作变比来降低直流电网损耗。
