A Medium-Voltage Carrier Peer-to-Peer Communication System for Intelligent Distribution Network

Abstract

A medium-voltage carrier wave peer-to-peer communication system for an intelligent power distribution network comprises a transformer substation communication network and an intelligent equipment communication network. The system is characterized in that the transformer substation communication network is composed of a transformer substation high-speed communication network and an in-station 10 kVoutgoing line interval carrier module; The intelligent device communication network comprises a carrier machine, a peer-to-peer group, a sectional type intelligent device and a contact type intelligent device. The in-station 10 kV outgoing line interval carrier wave module is composed of an uplink module, a grouping module and a carrier wave machine which are connected with one another. The grouping module collects data of different bus 10 kV outgoing line cabinet intelligent devices in the same transformer substation, carries out grouping according to a 10 kV primary loop, and distributes the grouped data to the uplink module and the carrier machine.

Description

technical field [0001] The invention relates to a medium-voltage carrier peer-to-peer communication system of an intelligent power distribution network. Background technique [0002] The State Grid Corporation of China's "Technical Guidelines for Planning and Design of Electric Power Communication Networks" clearly states that optical fiber, medium-voltage carrier and other solutions can be used for wired networking of 10kV communication access network. [0003] The intelligent power distribution communication network is based on the optical fiber communication network, supplemented by wireless private network and wireless public network, carrier technology and satellite communication technology. The intelligent power distribution communication network includes a backbone layer and an access layer. The backbone layer adopts an optical fiber communication network, covering substations, and used as a device for tandem access layer. [0004] In the construction process of smar...
