Abstract:

Building cooling, heating and power (BCHP)system is a highly efficient energy use patterns, which can provide electricity, cooling and heating.A distributed control system is used due to complication of the BCHP system involving different equipments, different seasons and different users.In this paper, a distributed control system based on programmable logical controller (PLC)and supervising computer is developed.It makes the whole system run automatically in different season work.Its control hardware and software are introduced and its control strategy is analyzed.

摘要：

建筑冷热电联产系统（BCHP）为建筑用能提供冷、热、电，是一种高效能源利用方式。由于系统所涉及的设备多，且由于季节的差别，不同用户的差别，导致了系统运行的复杂性，因此采用集散控制系统是非常必要的。本文结合一个工程实例，完成了一个基于现场可编程序控制器和上位控制计算机，并进行了建筑冷热电联产系统的控制策略分析，实现了整个系统的自动优化控制。
