Machine-furnace coordination autonomous switching control method responding to power grid frequency modulation

The invention relates to the technical field of thermal power generating unit boiler steam turbine coordination control, in particular to a turbine-boiler coordination autonomous switching control method responding to power grid frequency modulation, which comprises the following steps of: optimizing coordination control strategies in various modes, adding a primary frequency modulation pressure conversion function into pressure setting of a pre-turbine pressure controller in a newly added CCS-TF mode; and the defect of poor primary frequency modulation power response in the TF mode is overcome. The invention provides a turbine-boiler coordination autonomous switching control method responding to power grid frequency modulation, overcomes the defects in the prior art, effectively solves the technical defects existing in thermal power generating unit turbine-boiler coordination control under the current frequency modulation pressure, adds automatic switching coordination control logic to an original thermal po
