Metering automation system wireless communication failure prediction method

Abstract

The invention provides a metering automation system wireless communication failure prediction method. The metering automation system wireless communication failure prediction method includes: dividing history communication quality data collected by a terminal into a training sample set and a testing set; converting features extracted from the training sample set into a training vector set; training the training vector set based on a logistic regression model so as to obtain weight parameter vectors of feature vectors, and thereby obtaining a prediction model for predicting metering automation terminal communication failures; selecting features identical with features extracted from the training sample set from the testing set so as to build a test vector set; evaluating the prediction model obtained through training according to the test vector set, and adjusting parameters of the prediction model according to a prediction result. The metering automation system wireless communication failure prediction method can analyze data of the various communication failures, actively predicts a failure probability of a terminal, and thereby indirectly improves online rate of the terminal, and furthermore can effectively solve problems in communication failure prediction in a power grid.

Description

technical field [0001] The invention relates to the field of electric power technology, in particular to a method for predicting wireless communication faults in a metering automation system. Background technique [0002] Electricity is the lifeblood of national economic development and the supporting force for social production and life. The power grid shoulders the important task of delivering the electric energy provided by the power generation unit to the power consumption unit and thousands of households through the transmission, transformation, and distribution systems. It is the hub of the operation of the power system and the power market. If the measurement automation terminal communication fails, it will bring adverse consequences in terms of economic benefits, scheduling decisions, etc. [0003] With the continuous expansion of the scale of the power system and the increasingly complex structure, a large amount of alarm information floods into the power system di...

Problems solved by technology

[0005] The acquisition terminal of the metering automation system is transmitted to the data center using GPRS wireless communication technology. Due to the inherent characteristics of wireless communication and the wide distribution range, the quality of the GPRS signal of the terminal is unstable, and the post-maintenance delay of signal failure is large, which has a great impact on the system.
