Energy-saving optimization of technical water supply system based on combined control of pumps and valves
摘要
Abstract
[Objective]The technical water supply system is an important part of maintaining the safe and economical operation of hydropower units.To address the energy waste problem caused by the mismatch of cooling water supply and demand under the winter or low-flow conditions of the technical water supply system,[Methods]this paper proposes an energy-saving method based on pump-valve optimization control,taking a certain power station technical water supply system as the research object.First,a water supply network and variable frequency pump mathematical model that conforms to the engineering reality is established.Second,under the condition of satisfying the flow demand and pressure constraint,the pump speed and valve opening degree are taken as the optimization variables,and a pump-valve coordinated control and monotonic pump energy-saving optimization model under low-flow is established.Finally,the sand cat swarm optimization algorithm(SCSO)is used to optimize the parameters of the optimization model,determine the key parameters such as the pump speed and valve opening degree under the minimum pow-er consumption,and realize the system energy saving and water supply on-demand allocation.This paper conducts a simulation experiment of the energy-saving method and calculates the water supply flow and system power consumption before and after opti-mization.At the same time,the optimization model is simplified according to the actual situation of the power station,and the monotonic pump optimization model is obtained.[Results]The result show that:compared with the traditional control method,the system can save 9.85%and 6.4%of water consumption respectively after pump-valve coordinated control and monotonic pump optimization under the premise of meeting the cooling demand,and the energy saving rate reaches 15.18%and 12.75%respectively,which has significant advantages.[Conclusion]The result show that:the method proposed in this paper can realize the system energy saving and water supply on-demand allocation,and can provide a reference for the intelligent and energy-saving transformation of the hydropower station technical water supply system.关键词
