Abstract: A head allocation dynamic programming(HADP)model is established to optinuze the pump station pressure head in a trunk pipeline with the overall power cost for the pipeline as the objective function.A characterizing number of pump station operation state is introduced to deal with "pump bypassing",which,together with "pump on" represents the operation states with different upper limits for inlet pressure.Operatican conditions of closed system or open system,with or without branching point,rate regu lotion by changing impeller or changing motor speed are allowed far in the mode.A concurrent recursion algorithm is presented to make operation states recursion,funetional recursion,combination of operation.states,and redundancy elimination overlap concurrently so as to save computing time and storage space.A general computer program has been developed for this model and algorithm and has been used successfully in the trunk pipeline Tieling-Qinhuangdao.
