摘要
现代核电站采用数字化仪控系统,报警的数量与上一代核电厂相比将有所增加,同时数字化的报警显示方式不如常规光字牌显示方式直观,如果报警清单太长,将对操纵员处理重要报警产生一定的干扰。为了解决上述问题,需对那些操纵员不必关注的报警进行适当的"抑制"处理,使其不出现在报警列表中,以减轻操纵员的负担。通过报警抑制处理,有效过滤无关信息,突出重要报警信息,使报警系统更为简洁高效,满足《核电厂主控室的报警功能与显示》(NB/T 20027-2010)标准中对报警精简处理的要求。
In modern nuclear power stations, more digitized I&C systems are used, comparing with the previous generation of nuclear power plants, the quantity of alarms is increasing;and the digitized display pattern of alarms is not so intuitive as the conventional annunciators, if the alarm list is very long, the operators might be interfered for handling significant alarms. In order to solve above problems, appropriate suppression process has to be conducted for those alarms which are not very important, so they are not appeared in the alarm list to reduce the burden on the operators. Through alarm suppression process, minor information is filtered,while important information is highlighted;the alarm system becomes more effective and concise. This satisfies the requirements of concisely handling the alarm information in the standard "The alarm function and display in main control room of nuclear power plant" (NB/T 20027-2010).
