| Abstract: | Power oscillation in power system seriously affects the safe and stable operation of power system.The investigation and analysis of the causes of power oscillation events is to avoid similar power oscillation events and improve the security and stability of power system.In this paper,aiming at the power oscillation caused by abnormal excitation system,a set of rapid troubleshooting method is proposed.Taking the process of power oscillation accident in power plant as an example,the fault reason of the oscillation accident is confirmed through the method,so as to provide reference for accident treatment. |
