Optimizing Program in the Primary Frequency of the Circulating Fluidized Bed Unit

According to the situation of the actual generation in a power plant's 5 and 6 Unit,whose passing rate is too low.Therefore,we increase CCS blocking function logic method by adjusting the DEH internal frequency difference,we change callback rate in the process of variable load by primary frequency to extend the adjustment time with others forms,which avoid regulating insufficient even antitune status,meet the requirements of unit primary frequency in tune and improve primary frequency passing rate.Therefore ensure the long-time stable operation of primary frequency regulation control system.
