摘要
优化调度是实现梯级泵站系统节能降耗最有效的非工程措施之一,系统中的各类损失是影响优化调度结果的重要因素。相较于传统的仅考虑泵站抽水装置的损失,将渠道水力损失纳入优化调度的考量范围,以梯级泵站系统日运行费用最小为目标函数,构建考虑渠道水力损失的梯级泵站日优化调度模型,采用动态规划算法对模型进行求解。利用该模型对南水北调来水调入密云水库调蓄工程前6级泵站进行优化调度。结果表明:渠道水力损失对扬程优化分配的结果改变显著,所构建的模型能有效降低运行费用。
Optimal operation is usually one of the most effective non-engineering measures, which is used to save energy and reduce consumption in the system of multistage pumping stations. The results of optimal operation are heavily influenced by all kinds of losses in the system. Compared with conventional researches merely considering the losses in pumping units, a daily optimization model for muhistage pumping stations has been established, which takes account of hydraulic loss in channels, aims at minimizing the daily operation cost and is optimized by using the dynamic programming algorithm. The model is used to optimize the operation of the front six pumping stations in the South to North Water Diversion into Miyun Reservoir Storage Project. Results show that the hydraulic loss in channels would significantly change the optimal allocation of head and the operation cost can be effectively reduced by using this model.
