摘要
调速泵站在流量及水源水位变化时,若水泵运行组合不合理,导致泵站运行效率低。在考虑泵并联运行时进水管和连接管水力损失的基础上,提出以泵开机状态和调速率为设计变量,泵站流量和调速泵调速范围为约束条件,泵站总功率最小为目标函数的优化运行数学模型,并采用遗传算法对模型进行了求解。优化结果表明,模型及求解方法有效,可适用于调速泵站的优化运行。
If the operation combination of water pumps is unreasonable when the flow rate of speed-governing pumping station and the level of water source change,the pumping station operates with low efficiency.In consideration of the hydraulic loss of water pipe and connecting pipe of the pumps under parallel operation state,this paper presents the optimization model of pumping station operation by taking state parameters of water pumps and speed controling rate as design variables,flow rate of pumping station and speed regulation range of pumps as restraints,minimum total power of the pumping station as objective function.The optimization model is solved by using genetic algorithm.Result shows that the optimization model and solution method is efficient,which can be used in the optimizing operation of speed-regulation pumping station.
