The invention relates to a model used for carrying out primary
frequency modulation analysis coordination control on a boiler, a
steam turbine and a
power grid and particularly relates to a boiler,
steam turbine and
power grid three-party coordination control supercritical and super-supercritical set coordination control model used for carrying out primary
frequency modulation analysis. Control focus of
machine-network coordination and
machine-furnace coordination in the prior art is a
turbo generator set and a
power grid, only
negative feedback control strategies of grid
frequency difference are reflected in a primary
frequency modulation control loop, influence on the boiler is not considered, so a hidden safety trouble exists. The method for
problem solution is characterized by comprising steps that 1, a DC boiler mechanism model in a supercritical and super supercritical set is established; 2, a supercritical and super supercritical DC boiler controller model is established; 3, a
steam turbine primary frequency modulation model is established; 4, an
electric power system frequency modulation model including different types of sets is established; and 5, a steam
turbine power given
signal is corrected. The model is advantaged in that the model is applicable to the boiler, steam
turbine and power grid coordination control field.
