摘　　要：大容量水电机组电站水力系统过渡过程相对复杂,机组一次调频特性难以预测,为保证机组一次调频过程安全高效运行,水轮机调速器参数需合理设置。利用中国电建集团华东勘测设计研究院有限公司开发的HYSIM过渡过程仿真软件建立出相应的白鹤滩水电站百万千瓦机组一次调频仿真模型,将实际试验结果与仿真计算结果比较分析,验证了HYSIM软件的可靠性与准确性,为大容量水电机组的过渡过程仿真计算提供参考。同时利用建立的一次调频仿真模型,对调速器参数的一次调频特性影响规律进行了研究,研究成果可以为大容量水电机组的一次调频参数优化提供指导。The transition process of the hydraulic system of a large capacity hydropower station is relatively complicated,and the characteristics of the primary frequency modulation of unit are difficult to predict.In order to operate the primary frequency modulation process safely and efficiently,the parameters of the hydraulic turbine governor need to be set reasonably.Based on the character of the 1000 MW units in Baihetan Hydropower Station,the corresponding primary frequency modulation simulation model is established by using HYSIM transition process simulation software developed by PowerChina Huadong Engineering Corporation Limited.The reliability and accuracy of HYSIM software are verified by comparing the actual test results with the simulation results,which provides a reference for the transition process simulation calculation of large-capacity hydropower units.By using the established simulation model of primary frequency modulation,the influence law of primary frequency modulation characteristics of governor parameters is studied.The research results can provide guidance for the optimization of primary frequency modulation parameters of large capacity hydropower units.
