Embodiment 1

[0088] This embodiment provides a method for predicting the risk of stealing electricity based on deep learning, please refer to figure 1 , the method includes:

[0089] First, step S1 is performed: obtaining historical data from the actual application scene of the on-site metering equipment, and performing preprocessing on the obtained historical data.

[0090] Specifically, the historical data obtained is the original electricity consumption data. In practical applications, due to some external reasons such as personnel and equipment, sometimes there will be a lack of data items generated by one or more fields, and sometimes there will be a large amount of information. An error in the field. Therefore, the process of preprocessing the data is required, and the preprocessing includes steps such as data cleaning.

[0091] In one implementation, see image 3 , in step S1, the preprocessing of the obtained historical data specifically includes:

[0092] Step S1.1: Data sampl...

Embodiment 2

[0145] This embodiment provides a device for predicting the risk of stealing electricity based on deep learning, please refer to Figure 8 , the device consists of:

[0146] A preprocessing module 301, configured to acquire historical data from actual application scenarios of on-site metering equipment, and preprocess the acquired historical data;

[0147] A feature extraction module 302, configured to extract climate features and electricity consumption features from the preprocessed data;

[0148] The daily electricity consumption pattern prediction module 303 is used to use the extracted climate characteristics and electricity consumption characteristics as training samples, and predict the user's daily electricity consumption pattern based on the training samples and the deep belief network DBN;

[0149] The abnormal electricity consumption rate detection module 304 is used to calculate the abnormal electricity consumption rate by using the preset analytic hierarchy proce...

Abstract

The invention provides an electricity stealing risk prediction method and device based on deep learning. A solution is provided for the problems that in a traditional electricity larceny prediction method, an electricity larceny user cannot be positioned due to the fact that a topological structure in a power distribution network is not known, and the electricity larceny prediction accuracy is lowdue to the fact that a non-efficient identification feature is used in the traditional electricity larceny prediction method. The prediction method comprises the following steps: firstly, predictingthe daily power consumption mode quantity of a user by utilizing daily historical power consumption information of a low-voltage user; secondly, according to analysis of power utilization factors of the users in nearly three days of the day, an analytic hierarchy process is adopted to calculate the abnormal rate of power utilization, and finally, based on K <->, the abnormal rate of power utilization is calculated. And the Means method is used for grading the electricity stealing. Technical effects of improving prediction accuracy and realizing electricity larceny grade division are achieved.

Description

technical field [0001] The invention relates to the technical field of data mining and machine learning in computer science, in particular to a method and device for predicting electricity theft risks based on deep learning. Background technique [0002] The State Grid Corporation of China started the construction of the electricity consumption information collection system in 2010. At present, the collection coverage rate has reached 92.2% in the national power grid system, and 398 million smart energy meters have been installed. During the operation for about 7 years, a large amount of data of metering equipment has been accumulated. The data of multiple databases can be freely exchanged, and data mining technology can be used to conduct in-depth analysis of the characteristics of users' electricity consumption. [0003] In the process of implementing the present invention, the applicant of the present invention finds that at least the following problems exist in the met...
