Method for judging monitoring behavior reliability of digital master control room operator in nuclear power plant

Abstract

The invention discloses a method for judging monitoring behavior reliability of a digital master control room operator in a nuclear power plant. The method includes the steps: dividing each monitoring information source into a plurality of monitoring nodes according to the monitoring process of a digital master control room by the operator in a monitoring task; respectively determining time windows for monitoring behaviors of the monitoring nodes; determining the sequence of transferring the monitoring behaviors of the monitoring nodes by the operator according to the time windows for the monitoring behaviors; calculating the monitoring success probability of the monitoring nodes; and judging whether monitoring behaviors of the digital master control room operator in the nuclear power plant are reliable or not according to the monitoring success probability. By dividing each monitoring information source in the monitoring task, a mathematical model for the monitoring behaviors and monitoring transfer is built, the monitoring success probability of the monitoring nodes can be quantitatively calculated, and the monitoring behavior reliability of the digital master control room operator in the nuclear power plant can be finally judged.

Description

technical field [0001] The invention relates to the field of digital control of power plants, in particular to a method for judging the reliability of operator monitoring behavior in a digital main control room of a nuclear power plant. Background technique [0002] NUREG / RC (Regulatory guides, technical documents of the U.S. Nuclear Regulatory Commission)) series of reports have carried out a series of experimental observations and researches on operators' information acquisition behavior since the early 1980s when they studied operators' cognitive behaviors, and conducted a series of experimental observations and studies on nuclear power The monitoring behavior of the plant operator is defined, which refers to the cognitive behavior of obtaining plant information from the environment of the main control room of the nuclear power plant. That is, the operator observes the status of the power plant to determine the operating status of the power plant, including checking wheth...
