浅谈CAN总线技术及其在电站监控中的应用

介绍了现场总线CAN的原理和特点。利用CAN总线技术 ,针对新建及改建电站提出设计、改造方案。该方案采用分层分布式结构 ,任务功能模块化 ;CAN节点在严重错误的情况下自动关闭输出 ,不会影响其它设备的正常运行 ,使系统可靠性提高 ;系统通信速度快 ;抗干扰能力强 ;组态灵活。系统已在多个电站投入运行。

CAN bus technique and its application in monitoring and controlling of substation

The principle and character of site bus CAN is presented in this paper. It proposes a design and innovation scheme for newly built and innovated substations based on the CAN bus technique. The scheme is in layered and distributive structure and is of module for functions. The CAN node can close its output automatically in case of serious fault without effecting any other equipment's operation. This brings the system a high reliability, high speed communication, powerful anti-interference capability and flexible configuration. The systems in this technique are running in many substations.
