Thermal power generation flow control method

The invention discloses a thermal power generation flow control method. The method comprises the following steps that the flow and pressure flowing through any node in a circulating water system fluid network, a water supply system fluid network and a thermal power generation fluid network are obtained; flow data and pressure data of the circulating water system fluid network, the water supply system fluid network and the thermal power generation fluid network are combined to construct a flow and pressure mathematical model of the relationship between the flow data and the pressure data; by means of the method, the problems that in the thermal power generation process, due to the fact that the flow of a circulating water system cannot be effectively controlled, sea sundries often block a condenser titanium pipe, condenser vacuum declines, the safety and economical efficiency of a unit are affected, and potential unsafe factors of equipment possibly exist and cannot be eliminated can be solved; and the thermal
