摘要
针对锦屏二级水电站引水隧洞长,机组容量大、运行水头高,导致调压室水位波动稳定性以及机组间的水力干扰等较为突出的问题,对一次调频进行了深入分析研究,在满足电网安全的前提下,通过对机组一次调频进行仿真计算,得到了各种模拟工况下的机组开度、功率和转速的变化情况,为机组正常投入运行提供了可靠保证。
In Jinping II Hydropower Station, stability of the water level fluctuation in the surge tank and the hydraulic interference between generator units are rather serious because of the long diversion tunnel, large capacity of the genera-tor units and the high water head.Thus, the primary frequency regulation is analyzed in detail with simulations on the premise that the safety of the power grid is ensured.Changes of the unit opening, output power and the speed under dif-ferent working conditions are obtained, which are of great use to the normal operation of the units.
