VSC-HVdcs已被证明是提高输电系统稳定裕度的有效手段。适当的控制策略和输入信号的正确选择允许VSC HVdcs以显著的方式增强暂态稳定性、阻尼功率振荡并提供电压支持。本文研究了电压源型高压直流输电系统中POD控制策略中本地信息和远程信息的使用。两个主要的控制策略被认为是其中一个基于线性控制和其他一个基于非线性控制。作为本地信号，使用通过传输线的电流和VSC-HVdc的连接节点处的频率。发电机的转子角度和速度被用作远程信号。
VSC-HVdcs have shown to be effective means to increase margins of stability in transmission systems. An appropriate control strategy and a correct selection of input signals allow VSC-HVdcs to enhance transient stability, damp power oscillations and provide voltage support in a significant way. In this paper the use of local and remote information in control strategies for POD in the control of a VSC-HVdc are studied. Two main control strategies are considered one of them based on linear control and the other one based on nonlinear control. As local signals current through transmission lines and frequency at connecting nodes of the VSC-HVdc are used. Rotor angles and speed of the generators are used as remote signals.
