摘　　要：文中针对数字化核电厂软控制操作任务的特点展开分析,研究了由于人员误操作导致动作被纠正重复执行下的数字化主控制室任务执行模型。任务基本执行流程包括选择规程、选择屏幕、选择控件、执行操作,并在该模型下考虑操纵员由于任务执行失败重新纠正的过程。针对该模型下的操纵员任务负荷进行仿真分析,得到了影响主控制室安全的重要动作。其中检查记录类操作变化最为敏感,在人因失误增大到基础失误概率的50倍时,其任务负荷期望也增大了一倍。重要度最大的是视觉定位类动作,但随着人因失误概率的增加,其重要度在下降,而视觉检查类及相关诊断类动作的重要度上升。因此,在核电厂设计早期阶段的安全性评估重点要随不同场景进行调整。数据分析测试结果表明,尽管人因失误对于任务负荷的水平影响较大,但对于任务负荷的波动性影响较小。In this paper,the characteristics of soft control operation of digital nuclear power plant are analyzed,and the task execution model of digital main control room is studied under the condition that the action is corrected and repeated due to human misoperation.The basic process of task execution includes selecting rules,selecting screens,selecting controls and executing operations.In this model,the process of operator re correction due to task execution failure is considered.According to the simulation analysis of the operator's task load under the model,the important actions affecting the safety of the main control room are obtained.Among them,the inspection record operation is the most sensitive.When the human error increases to 50 times of the basic error probability,the task load expectation is also doubled.However,with the increase of human error probability,the importance of visual inspection and related diagnostic actions increased.Therefore,the focus of safety assessment in the early stage of nuclear power plant design should be adjusted according to different scenarios.Data analysis and test results show that although human error has a great impact on the level of task load,it has little impact on the volatility of task load.
