论文摘要
本文提出了一种新的相拟合测量单元（PMU）的宽区域阻尼控制（WADC）方法，以抑制大规模动力系统的关键区域间模式。通过实际无模型的系统识别方法估算的模态参与因子用于选择最合适的同步发电机通过所提出的WADC算法来控制。结果表明，在不影响其余模式的情况下，可以通过建议的方法充分抑制多个区域间模式，而只需要几个机器才能执行控制。提出的技术应用于IEEE 68总线和IEEE 145总线系统，包括带有PMU测量噪声和缺失PMU的测试用例。模拟结果清楚地表明了受到网络模型变化的控制策略的良好适应性，其与功率系统稳定器（PSSS）相比的有效阻尼性能以及其近乎实时实施的巨大潜力。
This paper presents a new phasor measurement unit (PMU)-based wide-area damping control (WADC) method to suppress the critical inter-area modes of large-scale power systems. Modal participation factors, estimated by a practically model-free system identification approach, are used to select the most suitable synchronous generators for control through the proposed WADC algorithm. It is shown that multiple inter-area modes can be sufficiently damped by the proposed approach without affecting the rest of the modes, while only a few machines are needed to perform the control. The proposed technique is applied to the IEEE 68-bus and the IEEE 145-bus systems, including the test cases with PMU measurement noise and with missing PMUs. The simulation results clearly demonstrate the good adaptivity of the control strategy subjected to network model changes, its effective damping performance comparing to power system stabilizers (PSSs), and its great potential for near real-time implementation.
