基于CAN总线和组态技术的变电站监控系统

Substation Supervisory System Based on CAN bus and Configuration Technology

针对当前中小型变电站监控系统中存在的智能化、数字化程度不高和不便于远程控制等问题,利用CAN现场总线技术和组态监控技术,提出了一种低成本的变电站监控系统的构建方案。详细阐述了监控系统的软硬件设计。实践表明,该监控系统具有可靠性高、通信速度快、抗于扰能力强、组态灵活等优点,有着广泛的应用前景。

To against the problems of difficult to implement remote control because of the low level of digitalization and intellectualization in current supervisory, and control systems for medium and small sized substations, by using CAN fieldbus and configuration monitoring technologies the stategy of establishing a low-cost supervisory and control system for substation is proposed. The hardware and software design of the system is described in details. The experience shows that the system offers high reliability, fast communication speed, strong anti-disturbance capability, and flexible configuration, etc. It has a wide prospect in applications.
