Title The research of smart substation communication network
Abstract
With the social and economic development, smart grid has become a international research topic. Smart devices are connected each other by communication network in every smart substation which plays a vital role of energy conversion and distribution in the smart grid. Currently, the increasing complexity of the grid structure and the increasing amount of message cause higher requirements for the smart substation communication network.
This dissertation analyzes the structure of smart substation and the construction of smart substation communication network and finally designs 220kV smart substation communication network in process layer. Meanwhile, this dissertation completes the system configuration, according to IEC 61850, in protection devices, measurement and control devices, merge units and intelligence terminal devices provided by Nari-relays. This dissertation also completes the building of smart substation communication network in process layer and analyzes the message. Finally, a software is designed to screen and analyze Goose and SV messages. This dissertation has important reference value in building the smart substation communication network.
Keywords Smart substation Communication network Process layer IEC 61850 Design Software
