摘要
冰蓄冷区域供冷系统设备多运行工况复杂,常规基于PLC的控制系统难以实现优化管理。本文以国家节能示范项目亚龙湾冰蓄冷区域供冷站为例,分析了项目特点与自控需求,采用基于能源管理的自控系统整体实现方案,创建了区域能源运营商与用户的协调管理平台,并对系统实行了逐时策略控制与运行定量分析。运行调查与实测显示,该自控系统可有效提高区域供冷系统的运行性能,实现高品质供冷、经济运行和节能减排的综合社会效益。
Ice storage district cooling system is more complex than conventional systems, and the PLC-based control system is difficult to achieve optimal management. In this paper,the automatic control system design of Yalong Bay ice storage district cooling station was introduced. Firstly, the project characteristics and automatic control demands were presented. Secondly, using the integrated solve strategy based on energy management, a coordinated management platform for the automatic control system was established. Thirdly,the quantitative analysis of hourly strategy control and real-time operation were provided. The survey and experimental results demonstrated that the presented automatic control system could achieve comprehensive social benefits of high quality cqoling supply, economic operation and energy-saving.
