基于CAN总线的励磁系统测量单元的设计开发

Design and Development of Measuring Unit of Excitation System Based on CAN Bus

同步发电机励磁系统对电力系统的可靠性和稳定性起着重要作用.针对我国励磁系统普遍存在部件藕合度大,故障易发率高,升级、维修困难等缺陷,为解决励磁系统切换逻辑复杂,不易于可靠控制的问题,构建了一种基于CAN总线的分布式励磁系统,并给出了励磁系统测量单元的硬件和软件设计方法.

Modern excitation system of synchronous generator plays an important role in improving the reliability and stability of power system nowdays. In China the problems are ： the connection among parts in excitation system is so tight it is easy to go wrong; it is difficult for maintenance and upgrade. In order to resolve the problems of switching logic complexity and controlling difficultly, a kind of distributed excitation system based on CAN bus is constructed. It also gives detailed hardware and software design of measuring unit.
