摘要
井群泵站水泵机组台数多,装机功率大,对其进行运行优化是减少能源消耗、降低供水成本的重要手段.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.以泵站提升1万t水耗电量最低为目标建立运行优化数学模型,应用枚举法结合matlab软件编程求解所有开机组合提升1万t水的耗电量.计算结果表明,不同开机组合提升1万t水的耗电量不同,其中最大耗电量与最小耗电量相差12.8％.选择合适的开机组合可以达到节约能源、降低运行成本的目的.
Abstract
The well group pumping station has a lot of pump units,the operation optimization of pumping station is an important means to reduce energy consumption and reduce the cost of water supply.In this research,we set up the nonlinear energy equations of the parallel operation of the pump,and solved the equations by Newton iteration method.Taking the minimum power consumption of supplying ten thousand tons of water as the objective,we established the mathematical model of operation optimization.Using enumeration method combined with matlab software programming,the power consumption was solved which used by all of water pump combination mode supply ten thousand tons of water.The calculation results showed that the power consumption of supplying ten thousand tons of water was different between different pump combinations,and the maximum difference reached 12.8％.The choice of suitable pump combination mode could achieve the purpose of saving energy and reducing the running cost.
