然后又結(jié)合某電廠循環(huán)水系統(tǒng)優(yōu)化運行方式的改造，給出循環(huán)水系統(tǒng)變速泵并聯(lián)運行優(yōu)化改造方案。通過建立變速泵并聯(lián)運行時的優(yōu)化數(shù)學模型，并編制了相應的優(yōu)化運行程序。 - 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
指出雙速電動機用于輸油泵的調(diào)速時，應選用轉(zhuǎn)矩按轉(zhuǎn)速平方降低特性的電動機；調(diào)速泵的運行經(jīng)濟性受到管路阻力特性曲線的限制，其調(diào)速范圍受到管路阻力特性曲線、系統(tǒng)所需揚程和泵運行特性的限制；在母管制系統(tǒng)中把部分定速泵改為調(diào)速泵時，應將性能較高的定速泵改為調(diào)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
在分析了蓄水池數(shù)學模型的基礎(chǔ)上，建立了含有蓄水池的供水系統(tǒng)優(yōu)化調(diào)度二級尋優(yōu)模型和直接優(yōu)化模型，并設(shè)計了遺傳算法適應度函數(shù)分別求解二級尋優(yōu)模型中的一級、二級尋優(yōu)，針對二級尋優(yōu)出現(xiàn)無解的情況，提出了放松約束處理和對一級尋優(yōu)得到的最優(yōu)水池水位進行修正的方法。
