基于现场总线技术的变电站综合自动化系统

Fieldbus - technology - based integrated automation system of substations

变电站综合自动化是电力自动化工作发展的长期目标，其在降低变电站造价、提高变电站运行安全可靠性两方面起着重要的作用。现场总线技术的日益成熟，给变电站综合自动化技术带来新的飞跃。就此，在介绍了现场总线技术的基础上，结合对国内外交电站综合自动化系统现状的分析，提出了一种采用ＣＡＮ总线技术的变电站自动化方案，具有较强的先进性和实用性。

Integrated automation of substations can reduce engineering costs and improve operational safety and reliability of substations. The development of fieldbus technology brings about a breakthrough in the integrated automation technology of substations. Therefore, based on the introduction of fieldbus technology and in light of the state-of-art of substation integrated automation systems at home and abroad, an advanced and practical CAN-bus-based automation scheme is presented in this paper.
