核电厂数字化主控室操纵员界面管理任务特征的研究

Characteristics of Operator Interface Management Tasks in Digital Main Control Room of Nuclear Power Plants

首先采用系统性人因失误减少和预测方法(SHERPA)分析操纵员界面管理任务中的关键行为;再用行为分析软件(INTERACT9)分析国内某数字化核电厂全范围模拟机上操纵员的操作录像视频,之后对INTERACT9采集的关键行为数据进行统计分析,得到4个操纵员界面管理任务的一般特征:①一、二回路操作员操作菜单栏、选择监视目标和打开参数界面的频率最高;②操纵员在选择进入不同系统界面的方式上趋向于选择从菜单栏进入;③一回路操纵员在正常工况和事故工况下的界面管理任务没有明显差异;二回路操纵员在正常工况下的界面管理任务明显少于事故工况;④正常工况下,一回路操纵员的界面管理任务显著多于二回路操纵员;事故工况下,一回路操纵员的界面管理任务与二回路操纵员的的界面管理任务相当。

This paper firstly analyzes the key behaviors of operators in the interface management tasks by using Systematic Human Error Reduction and Prediction Approach (SHERPA), and then uses INTERACT9, a kind of software, to analyze the video of the operator operation in the interface management tasks on the full range simulator of one nuclear power plant in China. After the statistical analysis of the data collected by INTERACT9, the four general characteristics of the tasks are obtained: a. The most frequent operations are conducted on the menu bar, the monitoring target and the parameter interface by operators in the first and secondary loop;b.The operators prefer to enter different system interfaces through the menu bar;c. The interface management tasks under normal conditions and accident conditions for the operators in the primary loop are generally the same, but the interface management tasks under normal conditions are significantly less than that under accident conditions for the operators in the secondary loop;d. Under normal conditions, the interface management tasks for the operators in the primary loop are significantly more than that in the secondary loop. Under accident conditions, the interface management tasks for the operators in the primary loop are equivalent to that in the secondary loop.
