摘　　要：为合理评估大型流域梯级水电站群发电运行对水资源的消耗,以金沙江中游梯级水电站群为例,提出了不同调度模式下梯级水电站群发电运行的水足迹研究方法,基于负荷曲线单独运行、负荷曲线联合运行、发电量最大联合运行三种调度模式下的短期优化调度结果,分别计算获得运行阶段的水足迹,并分析了不同调度模式对水足迹的影响。结果表明,水足迹能直观地反映梯级水电站群发电运行对水资源的消耗,梯级水电站群可改变调度模式来降低其发电运行的水足迹。For reasonably assessing water consumption of cascade power stations generation operation in large-scale basin,taking the cascade hydropower stations in middle reaches of the Jinshajiang River for an example,water footprint method of cascade hydropower stations generation operation in different scheduling modes is proposed.And then the water footprints in operation phase are calculated based on the results of short-term optimal scheduling in three scheduling modes,which are single operation based on load curve,joint operation based on load curve and joint operation based on maximum generation capacity.The effect of different scheduling modes on the water footprint is also analyzed.The results show that water footprint can directly reflect the water consumption of cascade power stations in operation phase;besides,the water footprint of cascade power stations can be reduced by changing its scheduling mode.
