基于LONWORKS的变电站远程数据监控系统

Remote Monitoring and Control System of Substation Based on LONWORKS

在概述变电站综合自动化系统中远动技术发展现状的基础上 ,指出传统的串行通信模式已无法满足大量实时数据传输的要求 .采用基于LONWORKS现场总线的变电站远程数据监控系统实现方案 ,运用现场总线技术代替传统的串行通信 ,不但改善了系统的性能 ,而且使系统可靠、灵活、易于扩展 .系统的现场运行结果表明 ,该方案对于实现变电站远程数据监控是有效的 。

Based on the brief description of the present development in substation automation systems, it is pointed out that the traditional series communication can not meet the requirement of real_time transmission for large amount of data. The distributed substation monitoring and control system based on LONWORKS technology is introduced in this paper. Compared with the traditional series communication, the fieldbus not only improves the whole system's performance, but also benefits customers with flexibility, reliability and expendability. The running results of the substation monitoring and control system based on LONWORKS show that the original idea is feasible to solve practical problems.
