Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, fig. 1 is a flowchart of a method for calculating an operating time of a nuclear power plant according to an embodiment of the present invention, and as shown in fig. 1, the method includes the following steps:
It should be noted that the embodiment of the present invention may be applied to multiple computer units arranged in a main control room of a nuclear power plant. And the operation time may refer to an operation time of an operator in the nuclear power plant, and the operation time may include an action time and a diagnosis time.
The specific type of the target person error event is not specifically limited herein, for example: the target human error event may be a break event occurring in the nuclear power plant or a cooling failure event occurring in the nuclear power plant, and of course, the target human error event may also be a medium break and a superimposed cooling failure event occurring in the nuclear power plant, which may be referred to as a "medium LOCA (superimposed cooling failure)" event.
The specific type of the target event information is not limited herein, and for example: the target event information needs to include all information of human error event descriptions, time windows, key signals, event trees, and accident processes.
It should be noted that the description of the human error event may be an expression or a generalized expression of key features or key information of the human error event, where the key features or key information may include a reason of the human error, and the like; the time window can be understood as: the target person cannot execute the mistime exceeding the time window.
In addition, information such as description of human error events, key signals, event trees, and accident processes can be various parameters for performing analysis of target human error events.
In addition, target event information corresponding to different target person false events is different.
And 102, determining a target guiding regulation corresponding to the target human error event according to the target event information.
The specific type of the target guidance procedure is not specifically limited herein, for example: the target-Oriented Procedure may include a State Oriented Procedure (SOP) or a Symptom Oriented Procedure (SEOP).
The SOP is independent of a specific originating event (which may also be referred to as an initial event), and is guided to enter a corresponding accident handling procedure by combining actual parameters based on a state represented by a unit. It can be understood that: and integrating event guide guidance, namely state guide and event guide, in the process of state parameter loop diagnosis. The SOP program implements closed loop control: diagnosis-action-supervision-redirection-action.
The above can be understood as follows: the following execution steps can be selected to be different according to different execution results in each step, namely, the state guidance and the event guidance are fused.
It should be noted that different target guidance protocols include different steps, and therefore, when the different steps are executed, the diagnosis time and the action time of each step are different, and further, the total time for executing the different target guidance protocols is different.
When the time consumption of each step included in the calculation of the SOP is long, the SOP adopts a cycle structure, and therefore cycle diagnosis is conducted on the unit state, the equipment availability and the like. Therefore, a certain step may be included in the SOP to be executed in a plurality of cycles, i.e. the diagnosis time and the action time of the step are correspondingly calculated a plurality of times.
The SEOP firstly uses event guidance to process accidents in time, and when complex accidents such as overlapping accidents occur, diagnosis processing is carried out by using symptom guidance, namely event guidance and symptom guidance. The sequence of each execution step of SEOP is a linear structure, and the design principle is simple and efficient.
And step 104, determining target time according to the elapsed time.
As an alternative embodiment, each step may include a diagnosis time and an action time, and the target time may include a target diagnosis time and a target action time, and the target diagnosis time may be the sum of the diagnosis times of the respective steps, and the target action time may be the sum of the action times of the respective steps.
As another optional implementation, when the target diagnosis time is calculated, different weight values may be given to each step according to whether the step is executed or not, the diagnosis time of each step is multiplied by the corresponding weight value, and the products of the diagnosis time corresponding to each step and the corresponding weight value are added to obtain the target diagnosis time.
Of course, as another optional embodiment, when the target diagnosis time is calculated, different weight values may be given to each step according to the importance of the step, the diagnosis time of each step is multiplied by the corresponding weight value, and the products of the diagnosis time corresponding to each step and the corresponding weight value are added to obtain the target diagnosis time.
Similarly, the target action time can also be calculated by referring to the target diagnosis time.
It should be noted that the steps of the embodiments of the present invention may include multiple sub-steps, and each sub-step may correspond to one execution action.
It should be noted that, after the target time is obtained by calculation, the time PSF of the target time may also be evaluated, so as to obtain the target time after evaluation. For example: the target time may be evaluated according to The NUREG/CR-6883The SPAR-H Human Reliability Analysis Method, (Appendix A HRA Worksheets for At-Power, Appendix B HRA Worksheets for LP/SD).
For example: and comparing and evaluating the target time with the time (namely the PSF horizontal time in the table 1) obtained in advance in the table 1, so as to finally obtain the target time after the comparison and evaluation (namely the accident diagnosis value in the table 1). It should be noted that the PSF can be understood as performance, that is, the PSF factor can be understood as a performance factor, and the target time is one of the PSF factors.
