摘要
在电力系统电压稳定分析与控制中,电压崩溃点的计算具有十分重要的意义。首先简单介绍了电压崩溃点的三类常用计算方法:直接法、基于连续潮流的计算方法和非线性规划方法。然后详细给出了一种利用非线性互补约束模型确定静态电压稳定临界点的方法,并在多个测试系统中进行测试,验证该计算方法的有效性。最后对本文工作进行了总结。
The calculation of voltage collapse point was of great significance in the power system voltage stability analysis and control. Firstly, the paper introduced three kinds of commonly used simple calculation methods of voltage collapse point：direct method, the method based on the calculation of continuous power flow and the nonlinear programming method. Then a method of determine the static voltage stability critical point was given by the nonlinear complementary constraint model and the effectiveness of the proposed calculation method in more than one test in the test system. Finally, the work done in this paper was summarized.
