摘要/Abstract

摘要： 针对变电站IED之间的互操作性差、难以实现信息交互的问题,结合变电站技术改造,探讨了基于VxWorks嵌入式实时操作系统的IEC61850报文实现。借助VxWorks的Wind微内核提供的多任务环境、进程间通信和同步功能,讨论了任务调度策略、通信、同步和互斥机制,研究了信息模型的通信映射与快速报文传输服务,构建了实现IEC61850的信息模型实体,分析了快速报文在Wxvorks中的实现,给出了最优推荐方案。变压器经济运行自投切换初步实验结果表明,IEC61850变电站自动化最新国际标准的实施有利于采用最新通信技术实现对电力参数的监控,为系统拓展预留了广阔的空间。

Abstract: Aimed at the puzzles of being poor in interoperability and difficult in implementing information interaction among intelligent electronic devices (IED) for substations,the paper explored the implementation of message transmission of IEC61850standard based on embedded real time operating system of VxWorks．By means of multitasking environment and function of communication and synchronization among proceedings offered by Wind micro-core of VxWorks,it discussed the task scheduling strategy,communication synchronization and mutual exclusion mechanism,researched the communication map of information model and transmission service of high-speed packets,constructed the solid information model implemented by IEC61850standard,analyzed the implementation of high-speed packets in the VxWorks,and also the optimal recommended scheme was given．The result of preliminary experiment in the spare powerautomatic switching of economic operation of transformer shows that date international standard of IEC61850substation automation is propitious to implementing the monitoring of power parameter by adopting date communication technology,and it obligates wide space for system prolongation．
