Metering apparatus operation state early warning method

Abstract

The invention discloses a metering apparatus operation state early warning method which comprises the following steps of: 1, selecting index information that can reflect an operation state of each part from offline input information and online monitoring information of four composition parts of an electric energy metering apparatus; 2, pre-processing data and performing abnormal data removal and replenishment on original data; 3, respectively establishing evaluation systems and carrying out scoring on the operation state of each part by applying an AHP comprehensive evaluation model; 4, carrying out data mining on the evaluation system of each part, selecting evaluation indexes with great influence on the operation states; 5, combining the online monitoring information and by a cloud self-adaptive PSO-BPNN predicting model, predicting a future operation state score value of each composition part; and 6, comparing the predicted operation state score values with an evaluation standard, determining the operation states of four composition parts, and timely giving out an early warning signal. According to the metering apparatus operation state early warning method which is provided by the invention, the operation states of the metering apparatus can be effectively subjected to early warning, thereby improving the pertinency, reliability and scientificity of detection of the electric energy metering apparatus.

Description

technical field [0001] The invention relates to a method for early warning of the running state of a metering device, which is used for early warning of the future running state of the electric energy metering device, and belongs to the technical field of electric power metering. Background technique [0002] The electric energy metering device is a device for measuring the amount of electric energy sold by the power supply department and used by the user. It is the legal basis for the trade settlement between the two parties. In order to grasp the operation data of electric energy metering devices in a timely manner, the State Grid Corporation of China has started the construction of an electricity consumption information collection system. Based on the number of customers at the end of April 2105, the coverage rate of the company's smart electric energy meters is 69.2%, and the collection coverage rate is 70.6%. , A total of 285 million households have collected electricit...

Problems solved by technology

This method of periodic on-site inspection has great shortcomings. On the one hand, on-site inspection is greatly affected by external factors, and it cannot be used to evaluate the normal operation status of the metering device. The safety risk of on-site work is relatively large; on the other hand, due to the lack of a real-time monitoring system, the failure of the electric energy metering device cannot be discovered and dealt with in time, which reduces the reliability of metering
