Summary:The primary frequency control(PFC) performance of thermal power units were affected by the problems such as equipment delay, nonlinear valve flow characteristic curve and weak controller parameters etc. Combined with the new integral electricity contribution index method, one dynamic compensation adjustment method of PFC based on real-time evaluation of performance indexes are proposed. The method dynamically adjust the control parameter by calculating the amplitude of PFC at the relevant time and the integral electricity contribution in the corresponding time period. This method not only improves the PFC performance based on the safe operation of the unit, but also helps to improve the PFC performance. It satisfies the power grid's standard and reduces the frequency fluctuation of the grid system.
