洪家渡水电站机组运行稳定性分析与保证措施

Analysis on the operation stability of generating units in Hongjiadu Hydropower Station and the guarantee measures

洪家渡水电站最高水头 16 4m、水头变幅高达 74m。电站在系统中担任调频、调峰及事故备用任务 ,运行工况复杂 ,机组运行稳定性至关重要。洪家渡水电站的机组从参数选择、水轮机流道设计、结构设计、水轮机的模型验收及运行方式等各方面进行了分析研究 ,并提出了保证稳定性的措施。

The Hongjiadu Hydropower Station has a maximum water head of 164 m with a variation of up to 74 m. It serves as a frequency modulation, peaking and emergency stand by station in the power system so that its operation conditions are complex. It is very important to keep the operation stability of generating unit. We have analyzed and studied various aspects of the generating units of the Hongjiadu Hydropower Station, including the selection of parameters, the design of flow channel of turbine, the structural design, the model acceptance of turbine, the operation modes, etc. Then we have put forward some measures for guaranteeing the operation stability of generating unit.
