摘　　要：介绍母线保护直采直跳方式的特点及网跳方式的延时问题,通过母线网跳延时计算实例分析网跳方式的特点,论证了各电压等级母线保护网跳方案的可靠性,提出各电压等级母线保护合理的跳闸方式,以提高跳闸的可靠性、简化网络连接,节省变电站投资。This paper analyses the characteristic of network trip mode in smart substation,calculates the busbar protection tripping delay under the two typical main connections of 220 kV and above voltage level in detailed,demonstrates the measures to reduce the queuing delay of network message,put forwards that the real-time could be significantly improved if the busbar protection trip message was seted to the highest priority,and could avoid the complex measures of message filtering.Demonstrates the reliability of busbar protection network trip scheme under every voltage level.,put forwards the reasonable busbar protection trip modes of every voltage level,to improve the reliability of the trip,simplifies the network connection,reduce the substation investment outlay.
