IEC 61850的XMPP映射方法

在配电自动化中应用IEC 61850可以提高设备之间的互操作性,减少通信配置和安装调试的工作量。针对配电自动化通信网络结构复杂、配电终端数量多的特点,文中提出了采用可扩展消息和在线表示协议(XMPP)传输IEC 61850的信息模型数据和实时数据的方法。首先,介绍了XMPP的基本网络结构和通信节点的地址格式,然后分析了XMPP的3种消息节,提出了消息节的应用方法。提出了IEC 61850映射到XMPP的方法,给出了信息模型获取服务、实时数据服务、在线信息等用可扩展置标语言(XML)消息表示和传输的方法。采用Openfire和Gloox开发了试验系统,并通过试验系统验证了IEC 61850映射到XMPP的方法能够满足配电自动化的要求。

Method of IEC 61850 Mapping to XMPP

Using the IEC 61850 standard in distribution automation can improve the interoperability of intelligent electronic devices(IEDs), and reduce the work of communication configuration and installation. In view of the characteristics of distribution automation communication network, such as complex network structure and large number of power distribution terminal equipment, this paper proposes a method of transmitting the IEC 61850 information model data and real-time data by the extensible messaging and presence protocol(XMPP), the basic XMPP network structure and the address of a communication entity are presented. Then, based on the analysis of three types of XMPP message stanzas, an application method of the message stanzas is put forward. The method of IEC 61850 mapping to XMPP is proposed, including the expression and transmission methods of information model accessing services, real-time supervisory data, and presentation data by extensible markup language(XML)message. By using Openfire and Gloox, a prototype system is developed. The solution of IEC 61850 mapping to XMPP is verified by the prototype system, the result showing that the method is able to meet the requirement of distribution automation.
