摘要
依据宏观模型建立管网压力控制曲线模型,模型经仿真检验其远端服务压力精度为±0.002 MPa,年运行能耗预测精度为±1.5%;泵群沿管网压力控制曲线模型运行,调节流量压力满足管网需求又无多余扬程,千吨水电耗降低7.62%;可在线优化分配流量及自动调节,使少数区域阀门减漏效应放大至整个管网以降低漏损量。
The network pressure control model was established based on a macroscopic model. The pressure accuracy of remote service was ＋ 0. IX）2 MPa by simulation and inspection, and the predicted accuracy of energy consumption in annum operation was -＋ 1.5%. The operation of pump group was accorded with network pressure control model. The regulated flow pressure was satisfied the network requirement and there was no spare lift. The electricity consumption was decreased 7.62% for thousand ton water. The model could optimize and distribute flow online, and it could regulate automatically. The leakage inspection by less valves could be expended to the whole network in order to decrease the leakage ratio.
