摘　　要：作为智慧供热体系架构中重要环节,城镇集中供热的换热站自动控制系统可通过采集现场机组运行的温度、压力、流量等参数,以及热量表、智能电表等远传表计的数据,来全面掌握换热站运行情况。以可编程逻辑控制器(PLC)为基础,结合电动调节阀和水泵的PID调节,实现定供水温度、定流量、分时段调整供水温度等控制策略,利用VPN专线技术实现跟数据采集与监视控制系统(SCADA)的通讯和指令下发。本文介绍了济南市某供热企业某小区换热站自动控制系统的设计和应用情况,读设计已推广应用到整个热网中。As an important part in the architecture of the intelligent heating system,the automatic control system of heat exchange stations for urban central heating can comprehensively grasp the operation status of heat exchange stations by collecting parameters such as temperature,pressure and flow during the operation of onsite units,as well as the data of remote transmission meters like heat meters and smart electricity meters.Based on the programmable logic controller(PLC),combined with the PID adjustment of electric regulating valves and water pumps,control strategies such as fixing the water supply temperature,fixing the flow rate and adjusting the water supply temperature in different time periods are realized.The communication with the Supervisory Control and Data Acquisition(SCADA)system and the issuance of instructions are achieved by utilizing the VPN dedicated line technology.This paper introduces the design and application of the automatic control system of a heat exchange station in a certain community of a heating enterprise in Jinan City,and it has been popularized and applied to the entire heating network.
