摘要: 针对建设新型电力系统要求常规水电机组具有更宽的负荷运行范围和更快速的调节能力的问题,以某水电站大型混流式水电机组为研究对象,开展宽负荷灵活调节改造研究,统计该水电站老旧机组十年间的运行特点及机组目前存在的问题,分析老旧机组不适应新型电力系统的原因及改造难点,提出改造技术方案并进行模型试验验证。研究结果表明提出的宽负荷改造方案切实可行,可为其他同类型老旧水电机组的改造提供参考。

Abstract: Aiming at the problem that building new power system requires conventional hydroelectric units to have a wider load operating range and faster regulation ability, taking a large francis turbine of a hydroelectric power plant as the research object, the research on the wide-load flexible regulation reformation is conducted, the operation characteristics of the old hydro turbine in hydroelectric power plant in the past ten years and the existing problems are counted, the reasons why the old unit does not adapt to the new power system and the difficulties in the reformation are analyzed, and the technical scheme of reformation is put forward and verified by model test. The results show that the proposed wide-load reformation scheme is feasible and can provide a reference for the reformation of other old hydroelectric units of the same type.

Key words: new power system, hydroturbine, wide-load reformation, hydraulic design
