区域能源水力输送系统控制方法的优化

Optimization of Control Method for District Energy Hydraulic Transmission System

目前供热/冷水力输送系统的水力损失一般认为与输送的流量或用户负荷对应。而实际的大型区域供冷/供热系统,由于用户距离能源站远近差异很大、入住率和入住时间等均有不同,造成能源站同一负荷或流量工况下,管路系统可能存在多个不同阻力损失。本文分析管网中所有用户不同负荷的组合模式下供水压力和流量的关系,通过调整控制方式,节省输送能耗。

The hydraulic loss of the current heating/cold waterpower conveying system is generally considered to correspond to the conveyed flow or user load.However,in the actual large-scale district cooling/heating system,due to the great difference in the distance between users and the energy station,occupancy rate and occupancy time,etc.,under the same load or flow condition of the energy station,there may be multiple pipeline systems.Different resistance losses.This paper analyzes the relationship between water supply pressure and flow under the combined mode of different loads of all users in the pipe network and saves the energy consumption of transportation by adjusting the control method.
