The embodiments of the present invention disclose a method and device for optimizing a control strategy of a desuperheating water valve, and a desuperheating water valve, including acquiring original action data of the desuperheating water valve; constructing a state-action sequence data set of the desuperheating water valve based on the original action data; The state-action sequence data set is used to build a simulated environment model of the thermal power generating unit through reinforcement learning algorithm; the optimization interaction of the preset optimization iterations is performed on the control strategy model of the desuperheating water valve and the state transition strategy model of the unit, and the optimized desuperheating water valve is obtained. Control strategy model. The embodiment of the present invention solves the technical problems of easy over-regulation and system instability caused by the delay of the system when the PID control strategy is used to control the desuperheating water valve in the prior art, and realizes that the delay of the system is considered on the basis of The technical effect of automatic and intelligent control of the desuperheating water valve avoids the harm caused by excessive adjustment.
Description
Technical field [0001] Embodiments of the present invention relate to the field of moistening the water valve control technology, and more particularly to a modified method, apparatus, and a temperature reduction water valve for a reduced temperature valve control strategy. Background technique [0002] In order to promote the ultra-low emissions and energy-saving transformation of coal-fired power plants, the comprehensive transformation of energy-saving and environmental protection, coal-fired boilers, to improve the comprehensive economic indicators of fire power generation. Among them, how to quickly cool down the superheated steam temperature in the boiler, maintain the exit temperature of the superheater in the constraint, and make the temperature of the tube wall do not exceed the allowable operating temperature, which is a key issue in the intelligent optimization in the fire power unit. [0003] Excessive tumors or too low will significantly affect the safety and economy...
