梯级泵站输水系统预测控制方法研究
Study on the Predictive Control Method of Cascade Pumping Stations in Water Transfer System
摘要
Abstract
The former part of Miyun Reservoir Regulating and Storage Project for incoming water from South?to?North Water Diversion Project is a complex water transfer system composed of pumping stations,open channels and check gates,etc. In order to solve the problem that wa?ter level may be beyond the extreme value constraint because of discharge imbalance in this cascade pumping stations in water transfer sys?tem,this paper established a predictive control method. The upstream water level of pumping station?discharge?volume relationship in each pool was established using the steady flow model,then variations of volume and upstream water level of pumping station could be predicted based on water balance and the interpolation calculation,finally the control strategy could be proposed. The predictive method was with high precision checked by the actual operation data,and the control method was simple and practical,which had guiding significance for practical operation control in this project.关键词
