Mixed Communication Design of Phasor Data Concentrator in Distribution Network

Abstract

Phase Data Concentrator (PDC) is an important part of Wide Area Measurement System (WAMS) and is widely used in transmission systems. WAMS technology will also be applied in smart distribution network, which has many nodes, complex architecture and various types of data transmission services, and a single communication mode cannot meet its needs. In order to solve this problem, this paper first introduces the composition of WAMS system, communication network mode, and discusses the access layer communication network mode. According to the main station, sub-station interaction process design a synchronous phase data set device that can carry out up-down communication and mix network by various means of communication. Finally, the experimental environment of Power Line Carrier (PLC) and twisted pair network communication is set up to verify.
