all-pass section

On the point of system , this paper mainly studies the optimal distribution of load in the machines of irrigation and drainage pumping station , the mathematical model and it ' s solution are studied among the machines in pumping station with two types of axial pump : full regulation or semi - regulation . this paper also studies the problems of the optimal day - operation of pumping station and the economical operation of grading pumping station . at the end , jiangdu pumping station is taken as a practical example to show the theory on economical operation of irrigation and drainage pumping station
本文从系统的观点出发，以排灌站机组间负荷的优化分配研究为主，分别对全调节和半调节轴流泵两种泵型的排灌站机组间负荷优化分配的数学模型及其求解方法进行了研究，同时对排灌站最优日运行方式及梯级泵站的经济运行也进行了初步探索，最后以江都排灌站为例，建立了排灌站经济运行的实用模型。
