【摘要】 针对云南某水电站,在优化导叶关闭规律的基础上,对两台水轮发电机组在额定水头、额定出力、全部甩负荷运行时的大波动过渡过程进行了计算.通过建立数学模型,采用特征线法,运用Matlab/Simulink软件对机组大波动过渡过程进行了模拟仿真,计算结果基本是可行的.研究为该水电站安全稳定运行提供了参考,同时为同类型电站在设计施工时计算大波动过渡过程提供了依据.更多还原

【Abstract】 For a hydropower station in Yunnan,the load rejection process of two hydroelectric generating sets from rated head and output was calculated on the basis of guide vane closure rule optimization.The mathematical model of this large oscillation transient process was built and solved with Matlab/Simulink and characteristic line method,and reasonable results were obtained.The results provide a reference for steady operation of this power station and a basis for large oscillation transient process calculation in the design and construction of similar power stations.更多还原
