| Abstract: | In the conventional model for the analysis of low frequency oscillation of power system, excitation systems are considered as the main component that causes the low frequency oscillation but turbine and its speed governor system are usually ignored. Based on the single-machine infinite bus system, the low frequency oscillation model is proposed in this paper, considering turbine and its speed governor. The results of eigenvalue relativity and sensitivity gained by Eigen-analysis showed that the turbine and its speed governor system do have influence on the low frequency oscillation mode of power system. |
