【摘要】：近年来,随着中国国民经济的快速发展,高层建筑像如雨后春笋般出现,传统的供电系统已经无法跟上时代的步伐,其复杂的结构、较低的效率的和完全依赖手工操作,不符合我国提出的节能减排促进环境保护的理念,因此,智能建筑逐渐受到青睐,在这种背景下,研究智能建筑的自动化配电系统显得尤为重要。本文主要针对楼宇自动化供配电系统进行分析,为楼宇自动化供配电技术的发展提供了一个新思路。本文首先对基于PLC的楼宇自动化供配电系统现状进行了分析,阐述了楼宇自动化供配电系统设计的基本要求,总结了楼宇配电系统中的常见问题。结合实际条件提出仿真楼宇自动化供配电系统的总体设计方案,并设定了具体的功能指标和性能指标。通过比对,选择PLC控制器作为控制核心,并通过搭配变频器、传感器等设备搭建楼宇自动化供配电平台。其后分别编写上位机程序和下位机程序,并提出了采用模糊-PID复合控制算法控制空调温度的方法,提高了控制的速度和准确度。最后,通过上位机程序控制PLC等设备,对楼宇供配电进行监控与调节,证明了该系统的有效性和可靠性。
[Abstract]:In recent years, with the rapid development of the national economy in China, the traditional power supply system has not been able to keep up with the pace of the times, its complicated structure, lower efficiency and complete dependence on the manual operation with the rapid development of the national economy of China. It is not in accordance with the concept of energy conservation and emission reduction and environmental protection proposed by our country. Therefore, the intelligent building is becoming more and more popular, in this context, it is very important to study the automatic distribution system of intelligent building. This paper mainly analyses the power supply and distribution system of the building, and provides a new idea for the development of the building automation power supply and distribution technology. In this paper, the present situation of the building automation power supply and distribution system based on PLC is analyzed, the basic requirements of the design of the automatic power supply and distribution system of the building are described, and the common problems in the building power distribution system are summarized. The overall design scheme of the automatic power supply and distribution system of the simulation building is put forward according to the actual conditions, and the specific function index and the performance index are set. Through comparison, the PLC controller is selected as the control core, and the building automation power supply and distribution platform is set up by means of equipment such as frequency converter and sensor. Then, the upper computer program and the lower computer program are respectively written, and the method of using the fuzzy-PID compound control algorithm to control the temperature of the air conditioner is put forward, and the speed and the accuracy of the control are improved. In the end, the control and adjustment of the power supply and distribution of the building are carried out through the control of the PLC and other equipment by the upper computer program, and the effectiveness and the reliability of the system are proved.
