Abstract
There are two modes of protection tripping in smart substation, including point-lo-point tripping and network tripping. These two modes of protection tripping have different Features: the point-to-point nipping transmission ttoes nol depend on the network, but has more light ports and melting points; the network tripping is realized through switches and has less light psrts and melting points, Different views exist on which Tupping modes should be adopted. An overview of the point-to-point-tripping mode futures are peovided in the paper, The reliability of the network-lripping is analyzed in terms of anti-electromagnetic-interence, inhibiting network storm and the higli load processing capability of switches. A theoretic analysis is made on the message transmission delay of the standaixl EC 61850 and the real-time nature of the network tripping is demonstrated. A testing of an experimental substation shows that the nelwcirk clelay is smaller thun the poinl-to-point delay and meets the speeiiiness requirements of relay protection tripping.关键词
