Problems solved by technology

[0002] With the increase of electricity customers and the diversification of customers' electricity consumption forms, there are more and more types of abnormal electricity consumption. The abnormal data generated by the system is large and the accuracy is low. The investigation and processing consume a lot of manpower and material resources.
Some abnormalities in power consumption cannot be detected and dealt with in time, which not only causes economic losses to power supply companies, but also threatens the safe operation of the power grid and personal safety
Among them, the investigation workload of zero-power users in abnormal power consumption is huge. In Zhejiang Province alone, there were 2.795 million zero-power low-voltage users in the third quarter of 2018. Using the original census method often consumes a lot of manpower and material resources, and sampling surveys often ignore many abnormal user

Embodiment 1

[0052] Such as figure 1 As shown, the main steps of this method are as follows:

[0053] Firstly, the multi-source data information of users is obtained from the power system metering collection system and marketing system, and by analyzing the multi-source data of users, the key factors for zero-power user investigation are extracted, including the basic attributes of users, the characteristics of power consumption of users, the characteristics of the station area to which users belong and The four characteristics of the important abnormal events of the user; then preprocess the data, fill in the missing key factors, and normalize each key factor, and establish a method to determine the weight of each key factor in combination with expert experience; finally, select The radar chart comprehensive evaluation method sorts the zero-battery users, obtains the investigation scores and order of the zero-battery users, and draws a comprehensive evaluation radar chart for each user, a...

Embodiment 2

[0103] The same as the first embodiment will not be repeated, the difference is that in this embodiment, the CRITIC method is used to determine the weight of the key factors of the zero-battery power user, specifically:

[0104] 4.1 CRITIC method

[0105] CRITIC is an objective weighting method suitable for determining attribute weights in multi-attribute decision-making problems. This method determines the objective weight of the evaluation key factors based on the contrast strength of the evaluation key factors and the conflict between the evaluation key factors. Among them, the contrast strength of the evaluation key factors represents the value difference of the key factors in different evaluation objects; the conflict between the evaluation key factors is measured by the correlation between the key factors. In this paper, Gini coefficient and Kendall coefficient are used to measure the value difference of key factors in different evaluation objects (that is, the contrast...

Abstract

The invention discloses a zero-electric-quantity user troubleshooting method based on a radar map comprehensive evaluation method, and relates to a zero-electric-quantity user troubleshooting method.An original general survey mode often consumes a large amount of manpower and material resources, and sampling survey often neglects many abnormal users. The method comprises the following steps: firstly, acquiring multi-source data information of a user; extracting zero-electric-quantity user troubleshooting key factors including user basic attributes, user electricity consumption characteristics, station area characteristics to which users belong and important abnormal events of the users; carrying out data preprocessing, determining the weight of each index; and finally, selecting a radar map comprehensive evaluation method to sort the zero-electric-quantity users, obtaining the troubleshooting score and sequence of the zero-electric-quantity users, drawing a comprehensive evaluation radar map of each user, and analyzing the overall score and the single index score of each user. According to the technical scheme, the troubleshooting priorities of the zero-electric-quantity users areranked, accurate positioning of the zero-electric-quantity abnormal users is achieved, the troubleshooting range is greatly reduced, and manpower and material resources are saved.

Description

technical field [0001] The invention relates to a zero-battery user screening method, in particular to a zero-battery user screening method based on a radar chart comprehensive evaluation method. Background technique [0002] With the increase of electricity customers and the diversification of customers' electricity consumption forms, there are more and more types of abnormal electricity consumption. The abnormal data generated by the system is large and the accuracy is low. The investigation and processing consume a lot of manpower and material resources. Some abnormalities in power consumption cannot be detected and dealt with in time, which not only causes economic losses to power supply companies, but also threatens the safe operation of the power grid and personal safety. Among them, the investigation workload of zero-power users in abnormal power consumption is huge. In Zhejiang Province alone, there were 2.795 million zero-power low-voltage users in the third quarter...
