Meter-transformer connection identification helps power companies achieve fine management of the power system as well as the energy saving and loss reduction of the power grid by judging the belonging of the station area.Power companies cause a lot of economic losses every year due to poor management.This paper studies the key technologies of Meter-transformer connection identification in the current power field,designs an efficient station identification algorithm based on voltage distortion data and a data collection algorithm based on stable connected routing,and thus improving the Meter-transformer connection identification from two main technical points:station identification algorithm and data collection.The relationship between the physical characteristics of the distribution network and the voltage distortion data is analyzed,and designed the Meter-transformer connection identification algorithm.Several cities in a province of China have proved that the algorithm is highly robust,and combined with the station identification algorithm,a route based on stable connectivity is designed.The data collection algorithm improves the speed of station identification while ensuring the accuracy of station identification.The main innovative work in the key technology research of station identification is as follows:(1)Clarify the dynamic relationship between the voltage distortion data and the user's electricity consumption behavior in the distribution network.Using this relationship and the physical characteristics of the power grid to design an efficient Meter-transformer connection identification algorithm.(2)Absorbed all the shortcomings of the past Meter-transformer connection identification and the completely independent data collection,we highly take the associativities of data collection and meter-transformer connection identification into account and proposed a data collection algorithm based on stable connected routing.Combined data collection and Meter-transformer connection identification together brings the increase speed of Meter-transformer connection identification and the signal reduction as well as the energy overhead in data collection.
