Primary Frequency Regulation Test and Parameter Tuning of Generator Units of Ertan Hydropower Station

The functions of primary frequency regulation of generator units are one of the important means to ensure the operation safety of generator units and power grid. In order to verify the functions and technical parameters of primary frequency regulation of generator units, testing of primary frequency regulation of generator units is necessary, and usually rank-jump frequency and open-loop method are adopted in field tests. Combined with practical conditions, the test method and test process of the generator units of the Ertan Hydropower Station are introduced, and the conclusion and the results of parameter tuning are given.
