基于全数字化棒位测量系统的通道比对分析

Channel data comparison analysis of digital reactor rod position measurement systems

反应堆控制棒的位置监测系统(简称为棒位系统)是反应堆功率控制的关键仪表与控制系统。随着反应堆的仪表与控制系统朝着全数字化的方向发展,秦山二期的4号反应堆棒位系统目前已变更为全数字化棒位测量系统,针对可能出现的故障问题,通过上位机通道实时测量数据比对分析来快速寻找故障点,方便了系统的运行和维护,提高了系统的可靠性。

The position monitoring system for reactor control(rod position system for short)is the key instrument and control system for reactor power control.With the development of the full digitalization of the reaction instrument and control system,the reactor rod position system of the No.4 reactor of Qinshan Phase II is currently changed to a fully digital rod position measurement system.In view of the possible failure problems,the method of quickly finding the failure point through the comparison and analysis of the real-time measurement data of the upper computer channel,which facilitates the operation and maintenance of the system and improves the reliable of the system.
