Control method for improving load response of primary frequency modulation

The invention relates to a control method for improving the load response of primary frequency modulation. The control method comprises: additionally arranging a rapid control module on the basis of a unit primary frequency modulation control system, receiving a rotating speed difference signal and a power output signal by the rapid control module, and overlapping the output of the rapid control module with a comprehensive opening command signal in an original system; setting a judging link in the rapid control module; setting a function link in the rapid control module; setting an integral link in the rapid control module; and in the rapid control module, setting a judging link and setting a gas turbine opening upper limit. The method can reduce the load difference in the modulation process and improve the unit safety on the basis of finishing the main modulation mission and cannot cause large fluctuation to unit parameters.
