| Abstract: | In the 110kV Xunbei substation in Zhejiang Province,critical real-time messages are transmitted on the process bus between bay devices and intelligence primary equipment.Messages of GOOSE and sampled values are transmitted on the same network,which results in the application of fault recording,bus-bar automatic transfer switch and low frequency/low voltage load shedding.Reliability calculating（using Markov state model）and the economic analysis show that the integrated devices and networks configuration are better than the conventional scheme using Ethernet switches in process layer. |
