Abstract: This paper introduces the principle of voltage fluctuation of UHV power grid and the reactive power control system of UHV power grid. Taking the voltage fluctuation of UHV power grid in East China as the research object, the mainstream AVC control optimization model and the method of building simulation platform are used for analysis. It is verified by application that the strategy can effectively improve the results of AVC assessment by dispatching institutions due to voltage fluctuation of UHV power grid. In engineering application, it provides an effective reference for improving the AVC qualification rate of power plants and reducing the AVC assessment of power plants by dispatching institutions.

Key words: automatic voltage control (AVC), AC UHV, grid voltage fluctuation, AVC pass rate
