摘　　要：水电站过渡过程关系到机组的稳定运行和电站安全。水电站过渡过程计算,实质上是解决水力惯性、机组惯性和调整性能三者的矛盾,以期达到电能质量最佳,水工建筑和机组造价最省的目的。通过建立永泰抽水蓄能电站输水系统数学模型,提出相应的计算条件和计算工况,并优化导叶关闭规律,进行过渡过程计算研究,确保上述三个参数指标均在控制值范围内,满足调节保证计算要求,进而确保机组的安全稳定运行。Transition process of hydropower station is closely related to stable operation of turbine generators and safety of the power station.Transition calculation of hydropower station resolves the contradiction between hydraulic inertia,turbine generator inertia and adjusting performance,so as to achieve the best power quality and to minimize the cost of hydraulic structure and turbine generators.By establishing the mathematical model of water conveyance system of power station,the corresponding calculation and working conditions are put forward.Moreover,the closing law of the guide vane is optimized.Furthermore,the transition process is calculated.It guarantees the three indices in the acceptable range,meets the requirement of the transition calculation,and guarantees the safety and stability of the units.
