Intelligent building energy management system

Abstract

The invention relates to an intelligent building energy management system. The intelligent building energy management system comprises a system configuration unit for setting an energy consumption management object and manager information, an energy consumption data acquisition unit for acquiring the energy consumption management object, an energy auditing management unit for auditing the energy consumption management object, an equipment energy consumption management unit for monitoring and managing in real time by taking equipment as a unit, a region energy consumption management unit for detecting and managing in real time by taking a region as a unit, an energy forecast management unit for counting and analyzing energy consumption data, an energy consumption alarm and demand control unit for controlling a demand according to a unit load group, a load and contract capacitance information, an energy evaluation unit for optimizing energy scheduling and balance, saving energy and improving reactive power consumption, an energy plan unit for making a rational energy use plan according to the current energy use situation, and an energy management database. By the intelligent building energy management system, the energy real-time balance management and monitoring management of building groups can be realized effectively.

Description

Technical field [0001] The invention relates to the application of computer network technology, database technology and computer control technology in intelligent building energy, and is particularly suitable for energy management oriented to enterprise management and business characteristics. Background technique [0002] The total annual electricity consumption of buildings in China accounts for 10% of the country's total consumption, and energy costs exceed 80 billion yuan. It ranks first in the world in terms of energy consumption per unit building area; the main reasons for these problems are: 1) Lack of scientific and effective power efficiency Management methods, such as not knowing where the electricity in the building is mainly consumed, how much electricity is consumed at what time, where are the loopholes of electricity waste, and what are the opportunities for improvement; 2) On the level of power distribution system and power quality , I don’t know how much reactive ...
