The information of digital substation is always use network which is easy to implement information sharing between the protection and made the secondary wiring of the system simply.How to make network configuration simply and data transmission reliably is have to discuss.The breaker protection in 3/2 structure is analyzed.According to the feature of protection that the configuration is not double but the output of protection is double and the contact between the breaker protection and the other protection

the GOOSE network solution is analyzed and the centralized network configuration program of breaker protection is proposed.Then the concentrate breaker protection function is illustrated and the rate of transmission of samples values is analyzed.Last the network configuration program of protection is determined.
