Embodiment

[0039]The specific implementation of the functional analysis method of comprehensive operation control under the accident state is as follows:

[0040] 1. Firstly, by sorting out the contents of each accident operation procedure, a list of functions used in the accident handling process is obtained. Determine the position weighting factor and frequency weighting factor of each function, and select the functions for modular design (such as primary circuit pressure control, regular monitoring of the main pump status, etc.) through the calculation and analysis of the weighting factors. The calculation method of the weighting factor is as follows: For example, if a function is used in the immediate action stage, its position weighting factor is W1, and the number of uses is frequency weighting factor P1; when it is used in the stable operation stage, its position weighting factor is W2, and the number of uses is Frequency weighting factor P2; when used in the transition stage to t...

Abstract

The invention belongs to the technical field of nuclear power design, and particularly relates to a function analysis method for operational control under accident condition of a nuclear plant with a digital human machine interface. The method comprises the following steps of firstly determining a selecting rule of function modules in accident operation regulations, screening the functions in the accident operation regulations according to the rule, obtaining a lift of functions which need to be treated with modularization design, then, integrating and screening the information of the function modules to determine an information list of comprehensive display control function, and finally, arranging the information list of comprehensive display control function according to an arrangement principle. The function analysis method is used for designing a related accident regulation comprehensive display control function, providing comprehensive monitoring and control information needed in the accident management process for operators, and improving accident management efficiency so as to reduce risks caused by accidents.

Description

technical field [0001] The invention belongs to the technical field of nuclear power design, and in particular relates to a function analysis method for operation control of a nuclear power plant under an accident state using a digital man-machine interface. Background technique [0002] Accident operation procedures (or emergency operation procedures) are used in the post-accident treatment of nuclear power plants to alleviate the consequences of the accident and bring the reactor to a safe standby state. In the accident operation procedures, the operation of the main functions of the nuclear power plant and the monitoring of relevant information are relevant and universal, and these functions often involve multiple systems and are highly comprehensive. For the main control room of the traditional hard operation panel, the operator can memorize the location of each equipment and monitoring information through continuous familiarization, thereby improving the efficiency of o...
