水电站水能计算及机组选型的动态模拟法

Dynamic Simulation Method for Hydropower Computation and Unit Selection in Design of Hydropower Station

针对传统的水电站水能计算与机组选型往往取决于经验、计算结果有时偏差较大的问题,提出了水能设计的动态模拟法,即将电站的水文过程、机组特性和调度控制作为一个整体,根据实时工况的效率计算实时发电量,以多年平均发电量最大为目标函数,求取最优的机组参数,从而确定机组型号,并将该方法应用于塘头水电站中,取得了较好的效果。

Aiming at the problem that the traditional hydro-energy calculation and unit selection often depend on the experience and the calculation results sometimes appear great deviation, a dynamic simulation method for hydro-energy design is proposed. This method takes hydrological process, unit characteristics and dispatch control as a whole, and calculates real-time power generation according to the efficiency of real-time working conditions. Taking the maximum average power generation for many years as the objective function, the optimal unit parameters are calculated so as to determine the unit type. This method has been applied to Tangtou Hydropower Station and achieved good results.
