摘要
IEC61850-9-2过程总线上的信息可概括为"只发不收(仅发布)"、"收发双向"(发布/订阅)"2类,针对大型变电站和中小型变电站信息流量的计算,在满足实时性和可靠性的前提下,过程总线宜采用集中组屏的"VLAN+多播"和"仅多播"2种形式。对于按间隔分散组屏的"VLAN+多播"过程总线,文中也进行了深入探讨,提出一种基于Hy-brid技术的高效实现方法。
The information on IEC61850-9-2 process bus can be summarized into two categories： ＂only send don＇t accept （only re- leased）＂ and ＂transmit and receive （publish/subscribe）＂ According to the information flow calculation for large substation and small and medium-sized substation, under the satisfied premise of real-time and reliability, process bus shall be centralized panel and taken in two forms of ＂VLAN ＋ multicast＂ and ＂only muhicast＂. According to the bay disperse panel with ＂VLAN ＋ multicast＂ process bus, this article also thoroughly discuss and presents an efficient method of realization based on a Hybrid technology.
