基于CAN总线和DSP的电力远动终端系统

Aystem of remotely operated terminal based on CAN bus and DSP

针对目前电力远动终端系统的串行通信模式及数据采集能力差且无法满足大量实时数据传输的要求的问题,介绍了基于CAN和DSP的变电站远动终端的设计与实现。系统采用DSP采集电参数提高了电力远动系统的实时响应能力和信号处理能力。采用的CAN总线集中了现场总线的结构灵活简单、可靠性好、易于维修等优点。本系统具有电力检测、谐波分析、事件记录等功能,很好的满足现代电力远动系统的发展要求。

In allusion to the problem of the serial communication pattern in power remotely operated terminal system and the poor ability in measuring parameters not to satisfy the transmission of real-time data,the design and realization of power remotely operated terminal system in substation based on CAN bus and DSP is introduced in this paper.In the system DSP is used to measure electrical parameters to enhance the ability of real-time response and signal process.And CAN integrates merits of flexible and simple structure,high reliability and easy maintenance.The functions of measuring the power parameters,harmonious analysis and event record are also involved in the system.So the system can satisfy the need of the development in power remotely operated terminal system.
