基于CAN总线的微机继电保护系统

The Power System of Microcomputer Protective Relaying Protection Based on CAN Bus

介绍了一种基于CAN总线的电力系统微机继电保护系统设计,设计了该微机保护系统总体结构,分析了传统模拟式继电保护装置的不足,给出了系统的硬件设计与软件设计流程。系统串行通信采用CAN现场总线技术,提高了通信的快速性、可靠性。

This paper introduces a power system microcomputer relaying protective system based on CAN bus. It illustrates briefly the total structure of the microcomputer protective system, and analyzes the shortage of the traditional analog relaying protection device. It also gives the system hardware and software design flow. The serial communication of this system adoptes CAN field bus, enhancing communication rapidity and reliability,
