摘要
在国内基于IEC61850的变电站自动化系统中,过程层交换机越来越多地应用于过程层设备和间隔层设备的连接,并逐步取代点对点的过程层拓扑结构。站内私有协议的消除使得大量设备可以通过过程层交换机发布或订阅信息,为避免设备间大量报文传输导致的冲突,需要对过程层交换机进行配置,交换机的配置越精细,获得的传输性能将越优良。通过过程层交换机的自动配置方法,能够降低过程层交换机配置的难度,节省调试工作量,使用户对交换机的管理成为现实,这将显著地影响未来智能变电站的设计。
In the Chinese SAS （Substation Automation System） based on IEC61850, process level switches are widely used as the connection between process level and bay level devices, which is taking the place of point to point topology of process level. The elimination of proprietary protocol in SAS helps more and more devices to publish and subscribe information through process level switches. To avoid the conflict caused by mass frames transmission between these devices, configuration is needed for process level switches. The more refined the configuration is, the better performance of frame transmission difficulty of process level switch configuration, lessen the work users to manage the switches, which will play an important role we can get. Automatic configuration can reduce the load for on-site commissioning, and make it easy for in the design of future SAS.
