在分析水电站调峰运行方式的基础上,探讨西霞院水库运行前后小浪底不同的调峰运行方式,建立基于西霞院反调节作用的小浪底水电站调峰模型,由模型计算结果得到小浪底水电站的综合调峰能力,制定小浪底日常规调峰计划和日联合调峰计划.分析比较结果表明,联合调峰运行明显增强了小浪底的调峰能力,在同时满足电调和水调指令的基础上优化了调峰电量的丰枯结构,提高了水资源利用率和发电企业的经济效益.%Based on the analysis of the peak load operation of hydropower station and combined with the practical operation situation, the different peak load operations of Xiaolangdi-before and after the operation of Xixiayuan reservoir-are discussed in this paper. The peaking model of Xiaolangdi hydropower station by anti-regulation compensation of Xixiayuan is established. The comprehensive peaking capacity of Xiaolangdi is gained from the calculated results of the model, on the basis of which daily general peaking load plan and daily joint peaking load plan of Xiaolangdi are formulated. The analysis and comparison of the results indicates that the joint peaking operation has obviously enhanced the peaking capacity of Xiaolangdi. On the basis of meeting both the water dispatching directive and power dispatching directive, annul structure of peaking power is optimized, whereby improving the water resources use efficiency and raising the economic returns of power generation enterprises.
