Aiming at the problem that the traditional user-transformer relation identification method in centralized station area based on high-speed power line carrier (HPLC) is prone to having identification failure when the equipment of different carrier manufacturers are mixed

a station area identification scheme based on distributed mode and double edge zero-crossing offset detection is proposed. A distributed identification mode is designed

in which the concentrator sends the station area characteristics to station (STA) through central coordinator (CCO)

compares the characteristics at STA and judges the ownership of meter station area. In addition

aiming at the compatibility of different HPLC communication modules with the feature signal zero-crossing detection algorithm

the AC signal double edge user feature acquisition and identification algorithm and the related communication protocol support are designed. Finally

the feasibility of the proposed scheme is verified by analyzing the reading performance of different identification modes and the examples of reading and identification failure.
