以有压管道非恒定流微分方程组为基础 ,结合碗牛坝水电站具体边界条件 ,建立了基于特征线法的描述水电站突甩负荷过渡过程的数值模型 ,全面细致地模拟出了该电站突甩负荷过渡过程中任一时刻压力管道任一断面各水力要素和机组各工况参数的瞬变规律 ,为该电站的设计及安全稳定运行提供了技术依据 ,对类似工程也有一定的参考价值。
Based on the differential equations of pressurized pipe with unsteady flow and the specific boundary conditions of the Wanniuba hydropower station, a numerical model describing the sudden load transfer process of hydropower station is established based on the characteristic line method. The transient law of each hydraulic factor and working condition parameter of any section of pressure pipeline at any time during the process of load transition provides the technical basis for the design and safe and stable operation of the power station and also has certain reference value for similar projects.
