Research on primary frequency compensation strategy of power grid received by ultra high voltage

In this paper, considering the technical requirement of primary frequency compensation(PFC) for ultra high voltage(UHV) construction of Shandong power grid, the basic concept and research status of primary frequency compensation of thermal power unit are introduced. In order to meet the frequency compensation requirements of power grid after accessing UHV, the optimization scheme of primary frequency compensation strategy for thermal power units is put forward, which has certain reference significance for the primary frequency compensation optimization of the same type of power unit.
