【摘要】 本文提出了一个实现梯级电站有功负荷自动优化分配的方法。方法系将连续变化的梯级水库的水位离散化,进而将全梯级系统的水位状态离散化为有限个水位状态,通过存贮于计算机的预先优化了的开机“优先级矩阵”,对梯级的当前状态自动形成优化的开机组合和负荷分配。按所提出的方法,对×××梯级电站编制了计算机程序。对几组方案计算结果表明,该方法是可行的。不仅所需机时短,占用内存少,操作简便,而且取得了明显的经济上的优化效益。由计算机自动形成的日调度方案比人工方案水耗率有所降低。更多还原

【Abstract】 This paper presents a method for realization of automatic optimum dispatch of cascade hydroelectric power stations. The method is to discrete the levels of cascade reservoirs which vary continuously, i.e, we descretize the level states of the whole cascade system into a finite number of level states. By means of the matrix of superior orders of starting water-turbine dynamos which is previously superiorized and storaged in the computer may utomate forming the optimum combination of starting water-turbine dynamos and the dispatch of active power for the current states of cascade. For certain cascade hydroelectric power stations, the authors have written a computer program for this method. The computing results for several design show that the method is feasible, the machine time is short, the reguirememt of the memory is small, the operation is simple, and we have gained an obvious economical advantage. The water rate of the day scheduling design which is formed automatically by the computer is lower than that of the manual design.更多还原
