时间: 2018-10-13 08:31 浏览次数: 来源:澳门游戏平台注册网站

  Abstract: The total area of ??large-scale public buildings is less than 4% of the total area of ??urban buildings, but the total energy consumption accounts for 22% of the total electricity consumption of cities and towns in China. The annual power consumption per unit area of ??large public buildings reaches 70-300KWh, which is ordinary residential buildings. 10 to 20 times. Public buildings are the key to energy conservation and energy conservation. Doing a good job in energy conservation in public buildings is of great significance to promoting and driving energy conservation in the whole society, achieving energy conservation and emission reduction targets, and implementing the major strategy of “transfer mode and structure adjustment”. This paper introduces the Shanghai Fudan Middle School West Campus project, using intelligent power meters to collect various electrical parameters of the power distribution site. The on-site system adopts the local networking mode. After the networking, it communicates through the fieldbus and travels to the background. The Acrel-5000 building energy consumption monitoring system realizes the monitoring and management of the power distribution circuit.

  Key words: large public buildings; Shanghai Fudan Middle School West Campus; energy consumption monitoring system; ACREL-5000;

  1 Introduction

  At present, China is already the world's second largest energy producer and consumer. Statistics show that China's building energy consumption accounts for about 28% of the country's total energy consumption. Of the 2 billion square meters of new buildings built in China each year, 99% of them It is a high-energy building; only 4% of existing buildings have adopted energy-saving measures. Large public buildings not only have high energy density, but also have very serious energy waste. They have huge energy-saving space. The promotion of building energy conservation is imperative, energy conservation and consumption reduction, and measurement first.

  Relevant local regulations require that “the building energy monitoring system should be included as part of the new construction equipment facility system and included in the construction plan; the Shanghai Fudan Middle School West Campus is a large public building, and the Shanghai energy consumption monitoring design basis is mainly “DGJ68-2068-2012”. "Technical specifications for energy monitoring in public buildings.

  3 Project Overview

  Shanghai Fudan Middle School West Campus project covers an area of ??23,237 square meters and a total construction area of ??54,403 square meters, including: a nine-storey experimental office building, a five-storey teaching building, and a comprehensive building. There is a gymnasium, lecture hall, library, a 12-storey dormitory building, and a single-storey underground parking garage.

  The project focuses on solving the intelligent, automated, visual, and quantifiable collection and storage of basic energy consumption data; establishing a school's energy management platform, achieving centralized management of various energy sources; and in-depth analysis of energy consumption processes and trends to achieve energy The close connection between management and life. Through the unified and comprehensive management of energy and other energy media in all regions of the school, the school can conduct query analysis on the energy use of equipment in various regions, help managers to identify potential energy-saving opportunities, maximize the energy efficiency of enterprises, and be scientific and effective. The management of the energy use of enterprises, thereby reducing energy use costs, plays a role in building a conservation-oriented society.

  4 system architecture

  Acre-5000 Building Energy Analysis Management System According to the actual situation of the Shanghai Fudan Middle School campus, the overall network structure is shielded twisted pair directly connected to the data collector of the weak well of the floor and then uploaded to the monitoring host through the optical fiber. .

  The system mainly adopts a hierarchical distributed computer network structure, as shown in the system structure diagram: station management layer, network communication layer and field device layer. Among them, Shanghai Fudan Middle School West Campus project site equipment distribution is as follows: 43 PZ96L-E4/KC, corresponding to the underground part 30 PZ96L-E4/KC; teaching building 20 PZ96L-E4/KC, corresponding to the underground part 21 PZ96L- E4/KC; 7 PZ96L-E4/KC in the gymnasium, corresponding to 10 PZ96L-E4/KC in the underground part; 54 PZ96L-E4/KC in the dormitory building, corresponding to 17 PZ96L-E4/KC in the underground part;
