Electricity energy efficiency monitoring and evaluating system applied to enterprise and evaluating method thereof

Abstract

The invention discloses an electricity energy efficiency monitoring and evaluating system applied to an enterprise and an evaluating method thereof. The electricity energy efficiency monitoring and evaluating system applied to the enterprise comprises a signal acquisition layer, a wireless communication layer and a system base station layer, wherein the signal acquisition layer transmits signals to the system base station layer through the wireless communication layer, and then the electricity energy consumption condition of the enterprise can be detected in real time and can be analyzed and evaluated objectively and practically. The evaluating method of the electricity energy efficiency monitoring and evaluating system applied to the enterprise is based on the analytic hierarchy process, and the weight ratios of all elements are calculated by means of an objective weight assignment method. By the adoption of the electricity energy efficiency monitoring and evaluating system applied to the enterprise and the evaluating method thereof, the electricity energy efficiency of the enterprise can be monitored in real time, the load of the enterprise can be managed, the type unification management of index data can be conducted by comparing the electricity energy efficiency of the enterprise with the industrial standard regulated in China or the industrial advanced level, the electricity energy efficiency of the enterprise can be evaluated objectively, and objective colors and a huge amount of calculation can be reduced as far as possible.

Description

technical field [0001] The invention relates to the field of electric power energy efficiency management, in particular to an electric power energy efficiency monitoring and evaluation system applied to enterprises and an evaluation method thereof. Background technique [0002] The application of energy information system in developed countries emerged in the 1970s, and has reached a relatively high level after decades of development. Energy management system is a system energy-saving technology developed in the mid-1990s in the world. The current energy management system is mainly used in steel, chemical, electric power and other process enterprises that consume a lot of energy. It uses production process control technology, network communication technology, optimization theory and technology to conduct comprehensive monitoring of the energy system of the enterprise and provide a basis for energy scheduling, and achieve the purpose of saving energy through systematic manage...
