Description
Technical field [0001] The invention relates to water turbine control technology, in particular to a method for controlling parameters of a water turbine adjusting system. Background technique [0002] The hydro-turbine regulation system is the core control system of the hydro-turbine unit, which is responsible for stabilizing the unit frequency and regulating unit power. The control law adopted by the system in engineering applications is generally Proportion Integration Differentiation (PID) control. PID control parameters have a decisive influence on the regulation quality and dynamic response indexes of the unit. How to optimize PID parameters has become a difficult problem in engineering applications. In actual operation, PID control parameters generally rely on expert tuning and lack automatic parameter tuning technology. In terms of theoretical research, there are studies to optimize PID control parameters through optimization techniques, and most of the commonly used opt...
