Study on Low Frequency Oscillation Mechanism and Control Measures of Power Systems
Pages: 42-44
Year: Issue:  5
Journal: Electric Switcher

Keyword:  低频振荡阻尼振荡共振机理电力系统稳定器;
Abstract: 首先分析了电力系统低频振荡的负阻尼振荡机理、产生负阻尼的系统条件;同时根据低频振荡的共振机理理论,分析了发电机二阶模型和考虑励磁特性的三阶模型产生共振振荡的机理;然后讨论了由于电力系统的非线性奇异现象引发的低频振荡的振荡起因和条件;最后,针对低频振荡问题提出了相关控制策略,并指出了其发展新动向和研究热点.
