摘要
建立了水轮机导叶两段关闭规律优化计算的数学模型，开发了相应的ＦＯＲＴＲＡＮ程序，求得导叶最优关闭时间及最佳拐点位置，使参数选择有了明确的目标，能得到最优关闭规律。实例计算表明，本文方法可用于有效地改善水轮机机组甩负荷过渡过程的综合特性，并能进行实际计算。
The mathematical model of the optimization of two step closure pattern of guidevanes in hydranlic turbine is established, the corresponding FORTRAN program is devel-oped,and the optimal closure duration of guide vanes and the optimal turning point are alsoobtained in this paper, which provide a clear object for the choice of the parameters and thebest closuere patterm,The optimization results show that the method presented can be usedto effectively improve the comprehensive characteristics of hydroclectric generator set in thetransient of load rejection,The methed mentioned above can be used in the engineering prac- tice.
