中文摘要
      提出一种符合水泵并联运行特性的最小流量偏差效率优化模型,克服了Cohen G.模型的不足.针对水泵高效区约束条件的复杂性,给出了简化高效区约束条件,明显缩短了优化求解时间,而求解精度基本不受影响.采用0-1完全枚举和Wolfe既约梯度等算法求解模型,得到满意的控制策略.实验结果证实了优化模型的有效性,实际应用效果良好.
英文摘要
      To remedy the defects of the flow difference model proposed by Cohen G.,an improved model is presented on flow difference minimization which satisfies the parallel characteristics of pumping stations.The simplified constraints are proposed to solve the solution complexity of precise constraints of high-efficiency operational areas to reduce the solution time greatly and maintain the precision.The 0 1 enumeration and Wolfe reduced gradient method was used to solve the model.It can obtain the satisfying control strategy.A lot of experimental results illuminated the validity of the optimization model.Some research fruits have been applied to real engineering with good performance.
