摘要
研究孤立运行的水电站的主控制系统。该电站采用微分方程建模,并将结果与实际水电站的现场数据进行了比较,偏差小于1.0%。另外,对主控制系统进行了研究,以确定控制器的最佳参数。研究了4种控制器:传统控制器、PI控制器、PID控制器和PI-PD控制器,通过稳定性准则和性能指标来评估控制器的性能。对于所研究的水电站,PI控制器具有最佳性能。
The purpose of this work is to study the main control system of isolated hydropower stations.The power station was modeled using differential equations and the results were compared with the on-site data of the actual hydropower station,with a deviation of less than 1.0%.A study was conducted on the main control system to determine the optimal parameters of the controller.Four types of controllers were studied:traditional controller,PI controller,PID controller,and PI-PD controller.Evaluate the performance of the controller through stability criteria and performance indicators.For the studied hydropower station,the PI controller has the best performance.
