Optimization of cost per day of cascade pumping station water-delivery system
摘要
Abstract
In order to improve the daily operation efficiency of cascade pumping station,through analyzing the cascade pumping station water delivery operation system,the concept and expression of the pumping station operation efficiency was proposed; and the influencing factors of daily operation costs and optimizing mechanism was analyzed.Based on the above researches,aiming at minimizing the daily operation costs,taking restricting conditions,such as time-of-use electricity price,water amount,and water level of intake and outlet pools,into consideration,a daily operation cost optimization model for cascade pumping station water delivery operation system,an efficiency optimization model of cascade pumping station water delivery operation system and an efficiency optimization model of single grade pumping station were established.Based on discrete intervals,adopting dynamic programming method,a daily economic optimization operation scheme for cascade pumping station water delivery system was determined,including inter-stage hydraulic (water level,water flow) plans and internal operation plans for all pumping stations.This method was applied to the optimization of Hanzhuang cascade pumping station water delivery system,which had greatly reduced the costs.关键词
