然后又结合某电厂循环水系统优化运行方式的改造，给出循环水系统变速泵并联运行优化改造方案。通过建立变速泵并联运行时的优化数学模型，并编制了相应的优化运行程序。 - It is indicated that , when a two - speed motor is used for driving oil transfer pump , the motor with the characteristic of torque reduction on square rotary speed should be chosen ; the working economy of the variable speed pump is restricted by the characteristic curves of pipeline resistance , and its speed control range is restricted by the pipeline resistance characteristic curve , the pressure head needed by the system and the working characteristic of the pump ; when several pumps work in parallel , the pump with better performance should be changed into speed - variable pump
指出双速电动机用于输油泵的调速时，应选用转矩按转速平方降低特性的电动机；调速泵的运行经济性受到管路阻力特性曲线的限制，其调速范围受到管路阻力特性曲线、系统所需扬程和泵运行特性的限制；在母管制系统中把部分定速泵改为调速泵时，应将性能较高的定速泵改为调速泵。 - At the same time , the implemental approaches of the genetic algorithm for water supply systems including both fixed and variable speed pumps were introduced . the direct optimal operation model and two - stage optimal operation model of water supply systems with one or more tanks were proposed , according to the hydraulic characteristic of storage tanks . appropriate fitness function of genetic algorithm was designed to solve upper level optimization and lower level optimization in two - stage optimal model
在分析了蓄水池数学模型的基础上，建立了含有蓄水池的供水系统优化调度二级寻优模型和直接优化模型，并设计了遗传算法适应度函数分别求解二级寻优模型中的一级、二级寻优，针对二级寻优出现无解的情况，提出了放松约束处理和对一级寻优得到的最优水池水位进行修正的方法。
