电力系统低频振荡的原因与对策

Causes and Countermeasures of Low Frequency Oscillation in Power System

分析引起电力系统低频振荡的多种原因———缺乏阻尼、发电机的电磁惯性、过于灵敏的励磁调节、电力系统的非线性奇异现象以及不适当的控制方式 ;重点比较并阐述抑制电力系统低频振荡 。

Some causes for the low frequency oscillation in power system, such as lack of damping, the electromagnetism inertia of generator, excessively sensiti ve excitation regulation, nonlinear singularity phenomenon, and improper control method, are analyzed. Some countermeasures against the low frequency oscillatio n aimed at the excitation system stability control are demonstrated especially a nd compared based on these causes.
