Electrical equipment energy efficiency chaos analysis method based on massive measurement data

Abstract

The energy efficiency chaos analysis method of electrical equipment based on massive metering data belongs to the technical field of electrical engineering, and in particular relates to a chaos analysis method for energy efficiency of electrical equipment based on massive metering data. The present invention proposes a chaotic analysis method for energy efficiency of electrical equipment based on massive metering data, which uses an advanced analysis method for metering data combined with a test detection system to analyze the relationship between the use of user electrical equipment and the user's power consumption data, and then Obtain the user's electricity consumption habits and the load characteristic relationship of different electrical equipment. The present invention comprises the following steps: 1) adopt fuzzy C-means clustering (FCM) to determine the degree to which the comprehensive load characteristic of the user belongs to a certain cluster with the degree of membership, and put n industry users x _i (i=1,2,,,n) is divided into c fuzzy classes, and the cluster center of each class is obtained, so that the weighted error sum of squares function within the class can be minimized.

Description

technical field [0001] The invention belongs to the technical field of electrical engineering, and in particular relates to a chaos analysis method for energy efficiency of electrical equipment based on massive metering data. Background technique [0002] At present, the characteristics of my country's electric energy structure are as follows: the proportion of high energy consumption industries is relatively high, and the industrial economy is extremely dependent on electricity, coal and other energy sources. Judging from the current situation at home and abroad, energy has become a key factor affecting the development and scale expansion of enterprises. However, with the rapid development of enterprises and the continuous expansion of scale, while the demand for energy continues to increase, the phenomenon of waste is also very serious. At the same time, the highest power load in my country generally continues to grow rapidly, the peak-to-valley difference increases, and ...
