摘　　要：为保证水电站的稳定安全运行,需要进行水力过渡过程计算,选择合理的机组关闭规律和机组运行方式,以保证机组的安全稳定运行和引水系统的安全。笔者采用定性计算和计算机仿真计算相结合的方法,对机组的大波动和小波动过渡过程进行研究计算,得出了相应的计算结果。根据对仿真计算结果和数据的分析,对机组的运行方式提出了合理的应对措施和要求,为机组的安全稳定运行和引水系统的安全提供了可靠的支持。In order to ensure the stable and safe operation of the hydropower station it is necessary to calculate the hydraulic transition process and select the reasonable unit closure law and unit operation mode to ensure the safe and stable operation of the unit and the safety of the water diversion system.The authors adopt the method of combining qualitative calculation and computer simulation calculation to study and calculate the large fluctuation and small fluctuation transition process of the unit and obtain the corresponding calculation results.According to the analysis of the simulation results and data reasonable measures and requirements are proposed for the operation mode of the unit which provides reliable support for the safe and stable operation of the unit and the safety of the water diversion system.
