Energy auditing and online energy efficiency management device

Abstract

The invention discloses an energy auditing and online energy efficiency management device. The device comprises a system setting module, an energy consumption data collection module, an energy auditing management module and an energy prediction management module and further comprises a real-time energy optimization module, wherein the real-time energy optimization module includes an acquisition unit used for acquiring grid parameters including a consumer power load, the unit capacity, consumer power consumption data and an energy storage component parameter, a processing unit used for optimizing the grid power according to the grid parameters, a harmonic absorption unit used for performing harmonic absorption processing of signals processed by a processor, and a power factor improving unitwhich is connected in parallel with the harmonic absorption unit and is used for improving the power factor of the grid. The device is advantaged in that not only can auditing be achieved, but also online energy efficiency management can be achieved, in addition, the grid parameters can be optimized, harmonics in the grid are eliminated, and real-time energy optimization is achieved.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of energy management, in particular to an energy audit and online energy efficiency management device. Background technique [0002] At present, the waste of electric power in our country is very serious; the main reasons for these problems are: 1) lack of scientific and effective means of electric energy efficiency management, for example, it is not clear where the electric energy in the building is mainly consumed, how much electric energy is consumed at what time, and how much electric energy is consumed. Where are the loopholes of waste and what are the opportunities for improvement; 2) At the level of power distribution system and power quality, it is not clear how much reactive power consumption is, and what is the power factor in that time period; 3) In terms of load and power quality At the equipment level, the central air-conditioning, lighting systems, boilers and other en...
