摘要
近年来随着水电的快速发展,各水电站都以大型机组为主,但现有的大部分水轮机调速系统的模型都是针对小机组建立的.重点分析了液压随动系统、引水系统及水轮机存在的非线性因素,建立了650 MW机组的非线性模型.在Matlab/Simulink中搭建了相应的水轮机调节系统非线性仿真模型,并根据云南省某水电厂650 MW机组进行了参数设置,通过仿真实验验证了该模型的准确性.
The nonlinear models are established based on the hydraulic servo system, diversion system and turbine, and the nonlinear presence factors are analyzed. Based on the operation parameters of 650 MW hydro power generating units in a hydroelectric power plant in Yunnan, a corresponding nonlinear turbine regulating system simulation model is established with Matlab/ Simulink. The simulation results verify that the model is correct and accurate.
