智能变电站通信网络状态监测信息模型及配置描述

Status Monitoring Information Model and Configuration Description of Communication Network in Smart Substations

建立统一的通信网络状态监测信息模型,并对通信网络配置进行详细描述是实现通信网络状态监测的前提。利用功能分解/信息提取、映射管理信息库等方法,初步建立了智能变电站通信网络的状态监测信息模型。对变电站配置描述语言(SCL)进行了扩展,提出了通信网络拓扑以及交换机等网络设备的描述方法,并针对某220kV变电站,给出了描述其过程层通信网络的SCL文档实例。

Unified status monitoring information model and configuration description of communication network is highly desirable to achieving status monitoring of communication network in smart substations.A status monitoring information model of communication network is developed to represent the operation state of different network functionalities by means of function decomposition/information extracting and mapping of the management information base（MIB）.The description method of physical network topology,protection devices and switch devices is also proposed based on the extension of substation configuration description language（SCL）.The process level communication network of a high voltage level substation is described in standard SCL files as an example,which demonstrates the availability of the proposed status monitoring information model and configuration description.
