摘要
随着国内核电开发的大繁荣,关于电站安全级控制系统,国内引入了几家有资质的厂家。国内某核电站安全级DCS系统采用的安全级平台,为提高设备的可靠性,减小系统故障的概率,该平台采用双CPU运行的模式,实际运行中出现了双系CPU数据不一致情况,该文对于不一致的原因与故障处理做了深入分析。
With the development of nuclear power stations in China, many kinds of safety control systems have been applied in nuclear power stations. One plant uses one safety system. To improve the reliability of facility and reduce the probability of facility failures, the system is equipped with two CPUs which run at the same time. Sometimes two CPUs give different data. This article discusses the reason of disaccord and the way to repair the thilures.
