摘要
在传统的特征根法的基础上,引入模式能量对电力系统低频振荡进行研究分析,并通过对4机2区系统算例的测试仿真,结果表明了本文方法的可行性与有效性,该方法可以直观且准确展示电力系统低频振荡的运动特性,更好地理解和认识电力系统共振机理低频振荡。
Based on the traditional eigenvalue analysis, the mode energy was used for analyzing the low frequency oscillation in power systems. By the tests on the 4 units and 2 regions system, the results showed the feasibility and efficiency of the proposed method, which can directly and accurately show the dynamic characteristics of the low frequency oscillation in power systems, and contribute to the understanding on the principles of low frequency oscillation in power systems.
