A kind of method promoting gas turbine group primary frequency modulation responding ability

The present invention relates to a kind of method promoting gas turbine group primary frequency modulation responding ability, including: (1) increases quick control module on the basis of unit primary frequency modulation controls, the output of this module and speed discrepancy is connected, and in the output of this module and original system, comprehensively opening degree instruction signal is superimposed;(2) arranging judgement link in quick control module, rotation speed change triggers when exceeding two turns per minute and starts;(3) function link is set in quick control module, controls the comprehensive aperture of gas turbine, regulate load;(4) integral element is set in quick control module, it is judged that unit load the most quickly responds;(5) the setting gas turbine aperture upper limit is set in quick control module.The inventive method quickly responds, and makes load change, and reduces the load deviation in mediation process, and aperture is provided with the upper limit, improves unit safety, does not results in the great fluctuation process of unit parameter.
