摘　　要：井群泵站运行方案的选择直接影响泵站运行费用。建立井群泵站水泵并联运行的非线性能量方程组,通过牛顿迭代法求解并联运行水泵工况点结合两部制电价计算出各运行方案对应的单方水耗电费。以井群泵站日运行耗电费最小为目标函数,建立了优化运行方案的线性规划模型。结果表明:优化运行方案中单方水耗电费低的方案所分配的运行时间长,符合预期;设计供水规模下优化方案比原方案节约日耗电费5.14%。对类似工程实现高效经济运行具有参考意义。The selection of operation plan of well group pumping station will directly affect the operation cost of pumping station. The nonlinear energy equations of parallel operation of pump in group pumping station are established. The Newton iteration method is used to solve the parallel pump operating point,and the two unit power price is used to calculate the corresponding water consumption and electricity bill.The linear programming model of optimal operation scheme is established by taking the minimum power consumption of the pumping station as the objective function. The results show that the running time of the single water consumption and low electricity tariff scheme in the optimized operation scheme is long and conforms to the expectation; the optimal scheme under the design of water supply scale saves 5.14% of the daily electricity consumption compared with the original scheme. It has guiding significance for similar projects to achieve efficient and economical operation.
