| 摘 要： | 由于中国能源分布在空间上的不均衡,且经济发展存在地区不平衡问题,决定了中国必然面临电力大规模远送问题。电能在远距离传输过程中容易出现振荡稳定性问题,在大区联网系统中,低频振荡成为了电力输送的瓶颈,造成电力设施利用率很低。本文从数学本质上论述了电力系统振荡和一般振动力学问题是一致的,综述了电力系统振荡稳定性研究现状,评析了现有研究方法的优点和局限性。在此基础上,提出了一些电力系统振荡分析与控制的研究思路,可供研究者参考。

| Abstract: | Due to the fact that energy resources are not distributed equably and economy is not developed averagely in China,power transmission through long distance is inevitable.However,oscillation stability problems are often produced in the course of transporting power energy.Low frequency oscillation is becoming an obstruction to power transmission in the large power system and utilization rate of power equipments is reducing.In this paper,it is proved that both power system oscillations and general mechanical vi... |
