| 摘 要： | 为了改善水轮发电机组调速系统的动态性能,应用可拓控制方法设计调速器.以无穷大容量水库-单引水管道-水轮发电机组-无穷大容量电力系统为对象,建立以水力系统弹性水击模型、水轮机线性化模型以及同步发电机经典二阶模型为基础的水机电整体仿真模型,对采用可拓控制方式与经典PID控制方式的控制效果进行仿真对比研究.结果表明,采用可拓控制方式对于改善水轮发电机组调速系统的动态性能具有良好的作用.

| Abstract: | A governor controller is designed by use of the extension control strategy to improve the dynamic performance of hydro-electric system.With the infinite-reservoir single-penstock hydro-governor infinite-bus system as the control object,a full hydro-machine-electric simulation model is established by integrating three models,i.e.,the elastic water hammer model of hydraulic system,the linearized hydro-turbine model,as well as the classical second-order model of synchronous generator.The simulation results ind... |
