Selection of communication and time synchronizing network in smart substation

With the intelligent grid construction fully evolving, to optimize the communication net?work of smart substation becomes a big issue. Combining with the different requirements of communi?cation network of smart substation, compares and analyzes different realization method of the innercontrol layer, process layer and time synchronizing network, obtains the optimization schemes of com?munication network selection inside smart substation.The research shows that under the current tech?nology condition, fully considers reliability and economy of network, realizes with reason constructingthe communication network in smart substation of different structure and scale, which has great signifi?cance for the stable operation of smart grid.
