摘　　要：本文介绍了一种基于光纤网络的分布式励磁控制系统,其智能功率柜在励磁调节器退出运行后可以通过自身通信状态和预置优先级选出替代的在线控制设备。本文提出了一种阳极电压运行方式供智能功率柜独立运行时使用。现场试验验证了智能功率柜切换逻辑的可靠性,也证明了阳极电压运行方式的实用性。A scheme of highly-redundant excitation system based on optical fiber networks is presented.When the excitation controller is out of work,one of the intelligent silicon controlled rectifier(SCR)is selected as the alternative controller according to its communication status and preset priority.Automatic anode voltage regulator is specially presented for the intelligent SCR.Experiments onsite verify the switching logic among controllers.And performance of the automatic anode voltage regulator is also proven to be good.
