The phenomenon of low frequency oscillation caused by large scale power networks interconnection has great damage to the stable operation of power system. This article mainly introduces how to simulate a large scale power networks in Matlab, and simulate the phenomenon of low frequency oscillation according to its mechanism. The results show that the model is reasonable in reflecting the actual situation, and it is a foundation for the research in how to inhibit low frequency oscillation of power system.
