摘要/Abstract

摘要： 为提升长江上游水资源利用效率,在“雅砻江和金沙江中下游梯级水库联合优化调度建模及应用Ⅰ—联合优化调度潜力分析”的基础上,进一步探究了雅砻江和金沙江中下游梯级上下游水库间和不同梯级间的运行规律,绘制了联合优化调度图,并分析了相关电站的蓄放水次序。研究表明:汛前金中、雅砻江梯级水库与金下梯级各水库消落开始次序宜为两河口—龙盘—锦屏一级—二滩—向家坝—白鹤滩—溪洛渡—乌东德,总体消落思路为上游水库优先消落,尽可能的保持下游溪洛渡、乌东德等电站高水位运行,提高流域整体发电效益;汛末各水库蓄水开始次序宜为锦屏一级—龙盘/二滩—两河口—乌东德—白鹤滩/溪洛渡—向家坝,总体蓄水思路为上游水库优先释放防洪库容开始蓄水,减轻下游防洪压力,且来水偏丰年份的蓄水时间相应有所推迟。

Abstract: On the basis of our previous potential analysis, we further probed into the operation rules between different reservoirs and different cascades, gave the joint optimal scheduling diagram, and analyzed the sequences of water impoundment and discharging of involved power stations to improve the utilization efficiency of water resources. Results demonstrate that the release sequence of the reservoirs before flood season should be: Lianghekou-Longpan-Jinping I-Ertan-Xiangjiaba-Baihetan-Xiluodu-Wudongde. The overall water releasing idea is to give priority to the upstream reservoirs and keep the downstream power stations such as Xiluodu and Wudongde operating at high water level as far as possible to improve the overall power generation efficiency of the basin. The order of water storage in the reservoirs at the end of flood season should be: Jinping I-Longpan/Ertan-Lianghekou-Wudongde-Baihetan/Xiluodu-Xiangjiaba. The overall water storage idea is to release the flood control capacity of the upstream reservoirs to start storage on a priority basis so as to alleviate the flood control pressure in the downstream, and the storage in wet years should be delayed accordingly.

Key words: wate resources utilization efficiency, cascades on Yalong River, cascades on middle and lower Jinsha River, joint optimal scheduling rules, scheduling diagram
