【摘要】 讨论了智能变电站和调度主站无缝通信的应用需求,特别是IEC 61850和IEC 61970共享建模等相关要求,论述了采用代理服务器模式实现变电站端通信网关装置的必要性和可行性,介绍了代理服务器的软件功能和架构设计。该代理服务器综合考虑了IEC 61850和IEC 61970的工程应用背景,包括建模方法、配置方式、实时数据库、IEC 61850客户端、服务映射、访问安全控制、管理维护、硬件选型等方面内容,功能完备,配置灵活,维护简单,可作为以后智能变电站基本的前置通信装置,为智能电网异构系统间实现无缝连接提供技术支撑。更多还原

【Abstract】 This paper deals with application requirements of seamless communication between smart substation and control center,especially model harmonization between IEC 61850 and 61970. The necessity and feasibility of IEC 61850 proxy server acting as a communication gateway in substation is introduced. It also describes software design of functions and architecture for proxy server. The proxy server makes full consideration of the application technologies of IEC 61850 and 61970,such as modeling methods,configuration tool,real-time database,IEC 61850 abstract communication service interface (ACSI) client,services mapping,access security,maintenance and hardware. The proxy server features perfect functions,simple configuration and easy maintenance,and will become an important front-end communication device in future construction of smart substation,providing technological support for seamless connections between heterogeneous systems in smart grid.更多还原
