Problems solved by technology

[0002] At present, the problems faced by the detection of electric energy meters are: my country has a vast territory and a high population density, and the terrain is mostly hilly and mountainous. The number of installations continues to increase, and the fault diagnosis of electric energy meters involves outdoor operations, etc.; these phenomena have led to a sharp increase in the workload of the State Grid Electric Power Company, and problems such as cumbersome on-site inspections and narrow coverage areas
[0003] The disadvantage of the existing diagnosis system is that it often needs to invest more software and hardware equipment in the construction, and it cannot make reasonable use of the software and hardware equipment and data provided by the existing electricity information collection system platform for remote diagnosis and early warning, especially The existing software and hardware equipment of the State Grid Electric Power Company’s power consumption information collection system contains massive data information (such as user classification, communication methods, user meter reading information, user daily / monthly frozen data, energy meter data, etc.), and the power consumption The data parallel processing module of the existing big data processing platform of the information collection system can effectively realize the massive data processing speed of complex models. Therefore, using the existing hardware and software equipment and data provided by this platform to establish a reasonable abnormal diagnosis model for information In-depth analysis and excavation to develop a remote fault diagnosis system for electric energy metering devices to assist the power consumption information collection system to achieve efficient calibration of electric energy meters and other equipment
[0004] To sum up, in the prior art, how to deal with the problems of cumbersome on-site detection and narrow coverage of the existing electric energy meter diagnostic system, and how to effectively use the existing electricity consumption information collection platform to monitor the operation status of electric energy meters in a remote, comprehensive and intelligent manner. , Accurate detection detection and maintenance problems, there is still a lack of effective solutions

Embodiment 1

[0062] In this embodiment, the State Grid Chongqing Electric Power Company is facing: Chongqing has a vast territory and a high population density, and the terrain is mostly hilly and mountainous. With the development of society and the continuous growth of population, the State Grid Chongqing The number of electric energy meters and other devices connected to the municipal electric power company is increasing, and the fault diagnosis of electric energy meters involves outdoor operations. At this stage, the State Grid Chongqing Electric Power Company has put into use the electricity consumption information collection system, which collects massive data information (such as user classification, communication mode, user meter reading information, user daily / monthly frozen data, electric energy meter data Wait). However, the prior art does not apply this system in the on-site state inspection of electric energy meters.

[0063] In order to solve the above problems, the present i...

Embodiment approach

[0065] A multi-dimensional electric energy meter field state inspection method based on decision tree group, the flow chart is as follows figure 1 As shown, the specific steps include:

[0066] (1) According to the collected data related to electric energy meters provided by the electricity information collection system of Chongqing Electric Power Company of the State Grid, 14207 cases of collected data related to electric energy meters were taken, and 70% of them were selected as the training set, that is, the number of samples in the training set was 9945 For example, select the remaining 30% of 14207 cases as the test set, that is, the number of samples in the test set is 4262 cases.

[0067] It is set to generate 11 decision trees, and 1 / 10 of the samples are randomly selected from the training set to form a sample training subset, and the overall training set is used as a sample training set, and a decision tree is established for the sample training set and the sample tr...

Abstract

The invention discloses a multi-dimensional electric energy meter on-site state test method based on a decision-making tree mass. The method comprises the following steps of building a decision-makingtree by using collected data related to an electric energy meter and provided by an electricity information collection system; forming next-level branches through classifying each decision-making tree; generating the completely grown primary decision-making tree; pruning and optimizing on the primary decision-making tree based on a cost complexity pruning algorithm; using an independent test setto assess the accuracy of the primary decision-making tree after pruning and optimizing; selecting the optimal decision-making tree from each set of secondary decision-making trees, and forming a decision-making tree abnormity diagnostic model by all the optimal decision-making trees, wherein a judgment result wins in a voting manner; and transmitting an operational rule of the decision-making tree abnormity diagnostic model to an electricity information collection system Hadoop big data processing cluster, thus implementing abnormity detection on the abnormal running state of the running electric energy meter.
