An Outdoor Installation Protection Plan Based On Ring Network And Reliability Research

Aimed at outdoor installation of substation site implementation scheme and the pilot station project under construction, This paper investigates the outdoor elements installation protection design combined with cross-interval outdoor installation of bus protection and transformer protection application demand, whose research meet the outdoor installation protection function to realize the communication mechanism, message format, as well as protecting the private network synchronization, reliability and other key issues. In conclusion, combined with the latest communication networking mode of substation, an outdoor component installation protection network communication scheme based on HSR ring network is proposed. At last, also the feasibility of ring network is simulated.
