本文提出了三种提高互联电力系统暂态稳定性的高压直流调制策略。交流变量，如转子速度，电压相量和联络线功率流被用作控制器的输入，通过HVDC链路修改功率流设置。所提出的技术进行了测试的IEEE 24节点可靠性测试系统和几个意外事件的临界清除时间进行了分析。本文表明，直流调制可以导致暂态稳定性的显着改善。
This paper presents three HVDC modulation strategies to improve transient stability in an interconnected power system. AC variables such as rotor speeds, voltage phasors, and tie-line power flows are used as input to the controller that modifies the power flow settings through the HVDC-links. The proposed techniques are tested on the IEEE 24-Bus reliability test system and critical clearing times obtained for several contingencies are analyzed. The paper shows that HVDC modulation can lead to substantial improvement in transient stability.
