摘　　要：由于自然及人为因素的影响,黄河上游近年来水量呈逐年减少的趋势,为满足万家寨水电站提高经济效益增强竞争力的需要,万家寨水电站实行水电站经济运行很有必要。经济运行可以充分利用有限水量降低单位功率耗水量。本文应用动态规划法对向山西电网供电的1到3号机组的经济运行进行了分析,根据机组运行区域即稳定运行区、过渡运行区和禁止运行区,引入惩罚流量来避开振动运行区,达到经济运行的目的。文中对5 0m、68m和80m三种水头下负荷最优分配作了详细分析。The runoff in the upstream of the Yellow river becomes less and less in the recent years on account of influence from both human and natural factors. In order to gain more economic benefits and strengthen the competitive ability, it is imperative for Wanjiazhai hydropower station to realize economic operation. Economic operation can reduce water consumption of specific power and make full use of limited water resources for power generation. The economic operation of 1 # - 3 # units supplying power for Shanxi electric network is analyzed by applying dynamic programming. On the base of the unit operation domains i.e. stable domain, transition domain and forbidden domain, the punished flux is introduced to avoid vibration and accomplish economic operation. The optimizational allocation of loads under the heads of 50 m, 68 m and 80m is analyzed in this paper.
