The embodiment of the invention provides a method and system for determining boiler heating parameters through a generated power order and belongs to the technical field of electric power automation control. The method for determining the boiler heating parameters through the generated power order comprises the steps that a generated power required value and a generated power actual value are obtained; the generated power required value and the generated power actual value are compared so as to obtain a comparative result; and under the circumstance that the comparative result is within the set range, the heating parameters of the boiler are determined according to the comparative result and the thermal storage characteristic of the boiler. Through the method, the control quality of a generator set is improved, control precision is improved, delay is improved, and response speed is increased.
Description
technical field [0001] The invention relates to the technical field of electric power automation control, in particular to a method and a system for determining boiler heating parameters based on generated power commands.
