摘要

电表的台区识别一直是泛在电力物联网中的一个难题，建立了一套类似于衰落信道的新分析模型，并基于有载调容调压配电变压器的远程有载调压功能，将信道编码理论应用于该难题的解决，为识别区域中不同台区的智能电表并同步施加不同的具有重复编码和分组编码性质的特殊调压图案，同时利用用电信息采集系统收集各智能电表在该时间段中的电压数据，最后基于译码算法的最小距离原则实现对每只电表的台区识别。理论分析和测试结果表明，和传统技术相比，新技术无须升级即可在现有电网系统中，实现对有载调容调压配电变压器台区中大量电表的高准确性台区识别，具有较高的工程应用价值。

Abstract

Station area identification has always been a problem in the ubiquitous power Internet of things

a new analytical model similar to fading channel was established for the station area identification

and based on the remote on-load voltage regulation function of on-load capacity and voltage regulation distribution transformer

the channel coding theory was applied to solve the problem.In order to identify station area of the smart meters

different special voltage regulation schemes with the properties of repeated coding and block coding were applied synchronously.At the same time

the power consumption information acquisition system was used to collect the voltage of each smart meter in this period.Finally

the recognition of each meter was realized based on the principle of minimum distance of decoding algorithm.The theoretical analysis and test results show that

compared with the traditional technology

the new technology can realize the high accuracy identification of a large number of meters in the on-load capacity and voltage regulation distribution transformer area in the existing power grid system without upgrading

which has high engineering application value.
