Abstract

The present invention discloses a preferred method of a water turbine adjustment system control parameter to carry out preferred selection of a PID control parameter in a water turbine adjustment system. A model is established according to the water turbine adjustment system, then a target function with a PID controller control parameter as a preferred variation is established according to a simulation system, and the preferred method designed by the invention is used to solve the target function to obtain an optimal PID control parameter. According to the preferred method of the water turbine adjustment system control parameter, a novel heuristic optimization algorithm is used to optimize the target function, a better target function value can be searched, and an obtained solution represents a better PID control parameter. According to the better PID control parameter, the frequency deviation of the water turbine adjustment system is small, the adjustment speed is fast, a system response curve is smooth, and the system adjustment quality is high.

Description

technical field [0001] The invention belongs to the technical field of hydroelectric power generation, and more specifically relates to a method for optimizing control parameters of a water turbine regulating system, which is used for optimizing the control parameters of a controller in the water turbine regulating system. Background technique [0002] The hydraulic turbine regulating system is the core control system of the hydroelectric unit, which is responsible for stabilizing the frequency of the unit and adjusting the power of the unit. In engineering applications, the control law adopted by this system is generally proportional-integral-derivative controller (Proportion Integration Differentiation, PID) control. PID control parameters have a decisive impact on the adjustment quality and dynamic response indicators of the unit, how to optimize the PID parameters has become a difficult problem in engineering applications. In actual operation, PID control parameters gene...
