Response execution reliability assessment method, device and equipment

Abstract

The invention discloses a digital nuclear power plant master control room operator response execution reliability assessment method. device and equipment. The method is used for solving the problems that the response executive human factor error probability is difficult to obtain through experiments and the quantitative evaluation result is inaccurate. The method comprises the following steps: obtaining a sample. The method includes acquiring a to-be-evaluated operation behavior in the target operation task, determining a state level of a behavior forming factor which corresponds to the mastercontrol room operator and the to-be-evaluated operation behavior and affects the response execution reliability; and obtaining a weight corresponding to the behavior forming factor, and obtaining a human error probability of response execution of the master control room operator to the to-be-evaluated operation behavior by using the weight and the state level, so as to evaluate the response execution reliability. Therefore, the human factor fault probability of response execution is obtained by using the comprehensive result of the state level and the weight of the behavior forming factor, the quantitative evaluation of the response execution reliability is realized, the final evaluation result is more in line with the reality, and the accuracy of the evaluation result is improved.

Description

technical field [0001] The invention relates to the technical field of human factor research, in particular to a method, device and equipment for evaluating the reliability of operator response execution in a digital nuclear power plant main control room. Background technique [0002] So far, there are many human reliability analysis (HRA) methods for the reliability analysis of response execution, such as the typical THERP method, HERA method, CREAM method, SPAR-H, etc., but the above methods are basically aimed at the traditional The simulated control system for analysis. Due to the new features brought about by digitization and soft control of nuclear power plants, the basic probability of human error may be changed. For example, the probability of human error may increase due to the complexity of interface management tasks. Therefore, the traditional HRA method and data may not be able to meet the requirements of the reliability evaluation of the operator's response in ...

Problems solved by technology

[0003] In view of this, the purpose of the present invention is to provide a method, device and equipment for evaluating the reliability of the operator response execution in the main control room of a digital nuclear power plant, which is used to solve the problem that the digital main control room is not considered when evaluating the reliability of the response execution. Situational environment and the revision of basic human error probability without adequate consideration of behavior shaping factors lead to inaccurate results
