摘要
变电站自动化系统在实现控制、监视和保护功能的同时,为了实现不同厂家的设备达到信息共享,使变电站自动化系统成为开放系统,还应具有互操作性。为此,国际电工委员会(IEC)制定了变电站内通信网络和系统标准体系IEC 61850。文章在分析IEC 61850标准的信息分层、面向对象的数据对象统一建模、数据自描述和抽象通信服务映射等概念的基础上,提出了一种符合IEC 61850标准的变电站内通信系统的框架模型。同时,遵循面向对象建模和抽象服务映射的思想,对变电站内智能电子设备(IED)统一硬件平台设计和软件系统的实现方法以及应该注意的相关问题进行了详细讨论,为变电站自动化系统的互操作性、可扩展性和高可靠性要求的实现提供了依据。
While its control, monitoring and protection functions are performed, a substation automation system should become a open system, i.e., to implement the information sharing of equipments from different manufacturers and to possesses interoperability. For this purpose, a standard for communication networks and system within substations, i.e., IEC 61850, is worked out by IEC. On the basis of analyzing the concepts of the information leveling, unified object-oriented modeling, dada object self-description and abstraction of communication service mapping, etc., a frame of the communication system within substations which is conformed to IEC 61850 is proposed. Following the idea of object-oriented modeling and abstraction of service mapping, the implementation of the software system and the unified hardware platform of intelligent electronic devices (IDEs) within substations as well as the problems should pay attention to are researched in detail. This work is available for reference in the implementation of the interoperability, expansibility and high reliability of substation automation system (SAS).
