The dual channel field system tracking technique based on state estimation

针对双通道可控硅励磁装置普遍采用的通道状态跟踪技术存在微机故障时切换可靠性较低的问题,提出一种通过发电机状态参数估测可控硅控制角度的跟踪技术.运用该技术研制的双通道励磁装置具有在线切换扰动小、微机故障情况下切换可靠性高等优点.

This paper presents a new tracking technology which estimating the control angle of silicon controlled through state parameters of generators. The technology can improve reliability which is low when using traditional channel status tracking method in dual channel silicon controlled microcomputer field system. A lot of engineering practices validate the new technology produces smaller disturbance and are with higher reliability when field system switches.
