摘要
为改善水轮机调节系统的控制性能,基于等效电路法建立了全流道引水系统数学模型,结合水轮机、发电机及调速器模型构建水轮机调节系统的整体模型.在此基础上,引入黏菌优化算法对水轮机调速器 PID参数实施优化.最后,在不同工况下进行仿真,仿真结果表明,SMA算法收敛速度快,寻优能力强,基于此算法的调速器使水轮机调节系统具有更好的动态稳定性,研究结果为实际工程应用提供了参考.
Abstract
In order to improve the control performance of the water turbine regulation system,a mathematical model of the full-channel water diversion system is established based on the equivalent circuit method.And then the overall model of the water turbine regulation system is constructed by combining the models of the turbine,generator and gover-nor.On this basis,Slime Mold Optimization Algorithm is introduced to optimize PID parameters of hydraulic turbine governor.Finally,the simulation results at different operating conditions show that the SMA algorithm has fast conver-gence speed and strong optimization ability.the governor based on this algorithm can make the hydraulic turbine regula-tion system have better dynamic stability.The research can provide a reference for practical engineering applications.
