Research on Energy Efficiency Assessment Method Based on Wavelet Analysis

Abstract

In order to evaluate the unreasonable power consumption of electrical equipment in office space, a method of energy efficiency assessment based on wavelet analysis is proposed in this paper. Firstly, the energy consumption data of equipment is processed by wavelet analysis. The moving average method and the hard threshold method based on sequence are adopted to deal with the high-frequency coefficients, and the unreasonable power consumption of the electrical equipment is distinguished. On this basis, an energy consumption assessment model is constructed by introducing weighting factors. During the course of the study, the energy consumption of office equipment for different personnel was monitored through intelligent socket for one week. Based on the energy efficiency evaluation proposed in this paper, the energy efficiency evaluation value of different personnel is given. Experiments show that the classification accuracy of personnel behavior is 93.38%, and it can realize the quantitative assessment of the rationality of the use of the people. This method can contribute to the meticulous assessment of the energy saving potential of the public building, carry out energy conservation guidance on the energy behavior, and provide reference for intelligent control of energy-saving technology.
