Research on the Effect of Governor System to Low-Frequency Oscillation of Power System

Abstract:

According to forced power oscillation theory, the opening of flow guide vane varies dramatically, when governor system occurs oscillation. At serious condition, prime mover’s output is affected, consequently the power system loses stability. Constructing generator and governor system modal, and then discussing the transfer function of each part, the statement indicates that dynamic characteristic can be rectified though phase compensation. as result the stability and dynamics characteristic of power system is also enhanced. Building a single-machine infinite-bus simulation model based on MATLAB, results verify the correctness of the theory analysis.
