摘要
智能变电站"共网共口"技术要求通信网络管理具有业务报文自动识别、分类处理的功能,通过对站内通信业务进行分析并梳理业务管理流程,提出了智能变电站通信业务自动发现方法。定义了通用业务报文格式,并利用终端设备对新业务报文进行解析,提取特征信息形成业务发现报文上报网管系统,从而完成了业务自动发现。研究了保护装置拓扑和业务的自动发现过程,结合网管系统软件开发,以SV/GOOSE业务为例,实现业务的自动发现与配置,验证了智能变电站通信业务的自动发现的有效性。结果表明,业务自动发现可减少网管系统业务配置工作量,方便工作人员进行业务管理。
Intelligent substation "shared-port and shared-network" technology requires the communication network management could identify and classify service message automatically. The substation communication services are analyzed and the service management flows are combed, then an intelligent substation communication service automatic discovery method is proposed. The method defines the common service message format and uses terminal devices to analyze new service messages and extracts the characteristic information, then service discovery messages are formed. System reports those messages to network management system to complete the service automatic discovery process. The relay protection device's topology and service automatic discovery process are studied. With software development of the network management system, SV/GOOSE service is taken as an example to realize the automatic discovery and configuration of the service, verifying the effectiveness of service automatic discovery method. The results show that, through automatic service discovery, network management system can reduce service configuration workload and facilitate the staff to conduct service management.
