基于改进PSO的水力发电机组励磁优化控制
Optimized control of excitation of hydro-generator sets based on improved PSO
摘要
Abstract
The global energy structure is accelerating its transition to renewable energy,and hydropower remains one of the main renewable energy sources.However,the impact of changing weather factors on power supply is becoming increasingly significant,making modern power grids require hydro-generator sets to quickly and accurately respond to disturbances.The excitation system directly affects the voltage stability of generators and may cause harmonic disturbances,affecting the power grid stability.Therefore,optimizing the excitation control strategy is crucial to improving the power grid stability.To address this problem,this paper establishes a mathematical model of hydroturbine governor and excitation system,and introduces a PID control strategy based on improved PSO algorithm into the excitation system.The algorithm changes the global inertia weight coefficient to prevent particles from falling into the globally optimal solution too early in iteration,and efficiently adjusts the PID parameters in the multivariable search space so that the excitation system can obtain better regulation effects under different conditions.关键词
