摘　　要：为研究长引水隧洞水电站的运行稳定性能,基于特征线法建立了封闭管道不定常流动模型;通过选取算例进行数值模拟,对机组导叶关闭规律、起动规律等进行了优化,并结合优化结果,对电站过渡过程进行了计算分析,为系统的优化设计和参数选择提供了参考依据。In order to research the operating stability of long diversion tunnel hydropower plant,a model of unsteady flow in closed tunnel based on the characteristic method is built in this paper. Through the numerical simulation of a certain long diversion tunnel system,the reasonable closing law of wicket gate and unit’s start-up rule are optimized. According to the optimization,the transition process of the hydropower plant is calculated and analyzed,which pro-vides a reference for the design optimization and parameter selection.
