| Abstract: | In the conventional model for the analysis of power system low-frequency oscillation,excitation systems are considered as the main components that cause the low-frequency oscillation;hydro turbine and governor system are usually ignored.In this paper,a low-frequency oscillation model considering hydro turbine and speed governor is proposed.The results obtained by using eigenvalue relativity and sensitivity analysis method show that the hydro turbine and governor system have influence on the power system low-frequency oscillation mode. |

| Keywords: | hydro-thermal system hydro turbine governor oscillation mode |
