| 摘 要： | 基于控制器局域网CAN(ControllerAreaNetwork)总线协议,针对电力系统接地故障较多的问题,设计了一种消弧及选线的电力保护系统。该系统由1台上位机和多台下位机组成,上位机和下位机以及下位机之间采用CAN现场总线进行通信,对该方案的硬件系统尤其是下位机系统进行了详细的设计,给出了软件系统需完成的各种具体功能,并根据CAN总线的通信协议规定了数据通信格式及地址的分配。实际运行结果证明了该系统的可靠性和有效性。

| Abstract: | Based on the CAN(Controller Area Network) bus protocol,an arc-extinction and groundingdetection system is designed for frequent grounding faults in power systems,which is composed of one superordinate computer and several subordinate computers,applying CAN field bus for communication among them. The hardware system,especially the subordinate system,is designed in detail,and particular functions of the software are given. According to the CAN bus protocol,the communication format and address assignment are specified. Practice shows its reliability and effectiveness. |
