摘要
西藏拉萨河干流中游已形成旁多、直孔水库组成的水电梯级结构。为了充分发挥两库的联合补偿作用,本文针对旁多、直孔水库群开展了联合调度方案研究。以原有水库单库调度方案为基础,建立了水库群联合调度模型,同时采用模拟-优化相结合的方法对联合调度模型进行求解,得到符合实际可操作的联合调度方案。长系列模拟结果表明:联合调度方案与原设计方案相比,水库群多年平均发电量为10.01×108 kW·h,增加了4.49%,同时两座水库发电量都有显著提高,取得了较为满意的结果。所制定的联合调度方案能够充分发挥水库群的联合调蓄作用,有效提高水能资源利用率。
The cascade hydropower system composed of Pangduo reservoir and Zhikong reservoir are formed on the middle reach of the main Lasahe river. For giving full play of joint compensation effect of the two reservoirs, the paper studied the joint operation scheme for Pangduo reservoir and Zhikong reservoir. Based on the respective operation scheme, a reservoir group joint operation model is built, the model is solved by the simulation-optimization method, and then the practical and operational scheme is achieved. The scheme could give full play of the joint regulation and storage effect of the reservoir group and improve effectively the utilization factor of hydropower resources.
