specific Embodiment

[0035] The results of applying the DBSCAN algorithm to cluster the historical data of the enterprise in the summer of 2016 are as follows: figure 2 shown. From the figure, it can be seen that there are three patterns of energy consumption in the enterprise in summer. Through investigation and analysis, these three energy consumption patterns correspond to "working hours on weekdays", "working hours on holidays, off-get off work hours on weekdays" and "off-get off work hours on holidays". energy use during the time period. Since a complex building closes at 10 pm and is in use on holidays, there are also higher energy consumption values ​​every night and on holidays.

[0036] After identifying the energy consumption pattern of the building, in order to analyze the discriminant conditions of the energy consumption pattern, it is necessary to construct two new attributes: energy consumption label and whether it is a weekend. Fill in the data cluster results obtained in section ...

Abstract

A real-time monitoring method for energy consumption of a high-energy-consumption enterprise based on a user side specifically comprises the following steps: 1, carrying out preprocessing and feature extraction on historical energy consumption data, and determining main energy consumption features, such as average energy consumption per hour and maximum energy consumption per hour; 2, recognizing an energy consumption mode contained in the historical energy consumption data, and marking in the data; performing classification training on the historical energy consumption data according to a marking result, and establishing an energy consumption mode judgment tree; 3, when new data is collected, judging the current energy consumption data to belong to an energy consumption mode, performing outlier analysis on historical data of the same energy consumption mode, judging whether the current energy consumption data is an outlier, if so, indicating that the energy consumption is abnormal, and giving an alarm and recording; and when the energy consumption data is not collected, judging whether a reconstruction period is reached or not, and if the reconstruction period is reached, executing the processes of recognizing the energy consumption mode and reconstructing the energy consumption mode judgment tree. The method has the beneficial effect of helping managers to timely and effectively know the energy consumption condition.

Description

technical field [0001] The invention belongs to the technical field of electric power system automatic control, and specifically relates to a method for real-time monitoring of energy consumption of high-energy-consuming enterprises based on the user side. Background technique [0002] my country's state-owned industrial enterprises consume more than 70% of their production costs. On the other hand, enterprises will also bear external costs for this, such as paying carbon emission taxes and environmental pollution fees. In addition, enterprises must also fulfill their energy-saving obligations and complete energy-saving targets. Therefore, the importance of energy consumption management in enterprise management has been further improved. [0003] Due to the wide range of energy consumption, it is difficult for industrial enterprises to monitor energy consumption in many cases, and the development of information technology provides a basic platform for solving this problem....
