摘　　要：以发电机组励磁调节器为控制对象,研究了双微机励磁系统之间数据跟踪及无扰动切换问题。为保证系统数据跟踪的实时性、故障检测的准确性以及故障切换的快速性,设计了一种基于双DSP的冗余热备用控制系统,通过eCAN通讯网络实现数据跟随,应用eCAN网络邮箱功能完成双机数据间的跟踪,合理运用DSP中断服务子程序进行故障识别,最后利用DSP丰富的软件功能完成对故障的报警和切换。基于以上思路开发的发电机组励磁调节器数据跟随及故障切换系统的实验测试结果表明:在典型励磁故障条件下,系统数据跟踪实时、准确,故障切换无扰动性极高,系统可靠性和可维护性明显提高。This paper,the generator excitation regulator as the control object,studies the data track-ing between the dual microcomputer excitation control system and bumpless transfer. In order to en-sure the system real-time data tracking,the accuracy of fault detection and quick failover,we de-signed the control system of a redundant hot standby based on double DSP. Through the eCAN com-munication network data,and through the eCAN network to follow mailbox function complete dual da-ta tracking,the DSP interrupt service subroutine was properly used for fault identification. Finally rich software functions of DSP were employed for fault alarm and switching. The experimental test of gener-ator excitation regulator of above ideas developed data follow and fault based switching system,and the operation results show that the typical faults in the excitation conditions,system data real-time, accurate tracking,disturbance of high fault free switching,system reliability and maintainability im-proved.
