[0028] Embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0029] The following describes the nuclear power plant data simulation method and device according to the embodiments of the present application with reference to the accompanying drawings.

[0030] Figure 1 A flow chart of a nuclear power plant data simulation method provided in an embodiment of the present application.

[0031] At present, the severe accident simulator needs to be connected to the full-range simulator. Therefore, the entire process of development and use of the severe accident simulator will have an impact on the corresponding full-range simulator. The scope of impact includes but is not limited to: the transformation of the full-range simulator platform system, the modification and debugging of the full-range simulation model, and the normal training of the full-range simulator platform cannot be kept in parallel with the training of the severe accident simulator, which reduces the training and use efficiency of the full-range simulator.

[0032] Among them, the full-range simulator is a device used to train and assess nuclear power plant operators and senior operators. It completely replicates the main control room of a nuclear power plant and reproduces the entire process of the nuclear power plant realistically and in real time on a computer through a mathematical model, simulating the normal operation and accident handling operations of the main control room.

[0033] In view of the above problems, the embodiment of the present application provides a nuclear power plant data simulation method, which is applied to an external severe accident simulator to ensure the normal simulation calculation effect and training frequency of the original full-range simulator. The formal development stage of the external severe accident simulator is completely separated from the full-range simulator, which does not affect the normal training use of the full-range simulator. Figure 1 As shown, the nuclear power plant data simulation method includes the following steps:

[0034] Step 101, obtaining initial simulation data, where the initial simulation data is historical simulation data of a nuclear power plant.

[0035] It should be noted that the external severe accident simulator can reproduce the operating data of the full-range simulator and the actual operating data of the power plant units, and can be separated from the full-range simulator without affecting the normal training use of the full-range simulator.

[0036] Optionally, subsequent data simulation is performed by reproducing the acquired historical simulation data of the nuclear power plant as initial simulation data.

[0037] The historical simulation data may be simulation data within a certain period of time before the current time, for example, simulation data within one hour before the current time.

[0038] Since the process of obtaining initial simulation data will not cause any changes to the model of the full-range simulator system, even if it is arranged during the normal training of the full-range simulator, it will not affect the normal use of the full-range simulation.

[0039] Step 102 , in response to entering the severe accident stage, screening the initial simulation data to determine target data.

[0040] Optionally, in the acquired historical data, if the temperature parameter reaches the preset temperature, it means that the nuclear power plant has entered a serious accident stage. In the serious accident stage, the steam turbine and other equipment in the secondary circuit have stopped running. By screening the running data in the initial simulation data as the target data, subsequent data analysis is carried out.

[0041] Step 103, inserting the fault data into the target data to perform simulation calculation.

[0042] Optionally, in the process of obtaining initial simulation data, simulation data when a fault occurs can be obtained as fault data. The target data is the data running during the severe accident stage. The fault data is inserted into the target data, and the target data is modified to realize the insertion of the fault and debugging during the severe accident stage. The scenario of the accident is simulated, and the target data after the fault is inserted is simulated and calculated to realize simulation calculation and obtain real-time simulation data.

[0043] In this embodiment, initial simulation data is obtained, which is the historical simulation data of the nuclear power plant; in response to entering the severe accident stage, the initial simulation data is screened to determine the target data; the fault data is inserted into the target data to perform simulation calculations, and an external severe accident simulator is used to reduce the impact on the full-range simulator system platform, the original model, and training use, thereby ensuring the normal simulation calculation effect and training use frequency of the original full-range simulator.

[0044] exist Figure 1 Based on the embodiment shown, this embodiment provides another nuclear power plant data simulation method. Figure 2 A flow chart of another nuclear power plant data simulation method provided in an embodiment of the present application.

[0045] like Figure 2 As shown, the nuclear power plant data simulation method may include the following steps:

[0046] Step 201, obtaining initial simulation data, where the initial simulation data is historical simulation data of the nuclear power plant.

[0047] In an embodiment of the present application, the first historical operating data of the full-range simulator and the second historical operating data of the power plant units are collected according to a preset receiving frequency; the first historical data and the second operating data are arranged in chronological order as initial simulation data.

[0048] The historical simulation data may be simulation data within a certain period of time before the current time, for example, simulation data within one hour before the current time.

[0049] In an embodiment of the present application, historical simulation data comes from a full-range simulator or partial simulation data provided by a real power plant unit, mainly including system interface data, fault interface data for fault simulation, equipment interface, event interface, etc.

[0050] Among them, the system interface data include: chemical volume control system, passive core cooling system, passive containment cooling system, secondary circuit system (steam generator system, main steam system, main feed water system, sewage system) and other system interface data.

[0051] The acquisition of initial simulation data provides a complete data source and data-driven library for the simulation calculation of the external severe accident simulator from the design basis accident stage to before entering the severe accident stage.

[0052] The data that the full-range simulator needs to provide during the calculation process can be extracted in advance through the external severe accident simulator. When the severe accident calculation is actually performed, there is no need for the external severe accident simulator and the full-range simulator to run at the same time, which can free up some resources of the full-range simulator.

[0053] Step 202, in response to entering the severe accident stage, selecting the operation data of the severe accident stage from the initial simulation data as the target data.

[0054] Optionally, based on the core outlet temperature, it is determined whether the nuclear power plant has entered a severe accident stage.

[0055] In the embodiment of the present application, in response to the core outlet temperature being greater than or equal to a preset temperature, it is determined that the nuclear power plant has entered a severe accident stage. As a possible implementation, the preset temperature is 650°C.

[0056] It should be noted that the initial simulation data is the simulation data within a certain time period before the current moment. If the current moment has not entered the serious accident stage, the initial simulation data is the simulation data of the full-range simulator within a certain time period obtained; if the current moment has entered the serious accident stage, the initial simulation data includes not only the simulation data of the full-range simulator, but also some data calculated after entering the serious accident stage.

[0057] After entering the severe accident stage, the steam turbine and other equipment in the secondary circuit have stopped running. The severe accident analysis software is mainly responsible for the simulation calculation of the core, primary circuit, steam generator and the phenomenon in the containment. For example, after entering the severe accident stage, the nuclear power plant may lose power and fail to start the safety facilities (fail to start the water supply), resulting in core melting. By screening the running data in the initial simulation data as the target data, subsequent data analysis is carried out. However, before entering the severe accident stage, the operating data of the secondary circuit still needs to be paid attention to.

[0058] Step 203, inserting the fault data into the target data to perform simulation calculation.

[0059] In the embodiment of the present application, in the initial simulation data, the operating data where the fault occurs is extracted as the fault data; in response to triggering the fault event, the fault data is inserted into the target data using the fault interface.

[0060] Among them, fault data may include fault interface data, device interface, and event interface.

[0061] Furthermore, during the severe accident stage, faults may continue to occur. For example, a breach in a circuit may occur during the simulation process. The breach may be artificially enlarged or reduced to modify the fault data. The fault data is then inserted into the target data to simulate the fault.

[0062] As a possible implementation, based on the switch state of the valve, the device interface data can be determined, for example, during the training process, the device is started and shut down, the device interface data is determined, and inserted into the target data.

[0063] As a possible implementation method, in different scenarios, event judgment is performed to determine whether an event occurs, so as to determine an event interface and insert it into the target data.

[0064] Among them, the method of inserting fault data is to modify the target data, such as adding, modifying, deleting, etc. a single point of data, or adding, modifying, deleting, replacing, etc. the whole end of a time series.

[0065] Optionally, a preset severe accident analysis program is used to update input data in real time, wherein the input data is data after the fault data is inserted into the target data.

[0066] The data updated in real time is the data obtained by simulation calculation, which can be displayed in the user development interface. Furthermore, the data obtained by simulation calculation can be presented in the form of a two-dimensional monitoring interface and a three-dimensional dynamic display model to meet diverse training and display needs.

[0067] Furthermore, during the operation phase, the interface data of the severe accident analysis software can also be modified online in real time to implement fault insertion, action of related equipment, and triggering of events.

[0068] In this embodiment, initial simulation data is obtained, which is the historical simulation data of the nuclear power plant; in response to entering the severe accident stage, the operating data of the severe accident stage is selected from the initial simulation data as the target data; the fault data is inserted into the target data to perform simulation calculations, and the impact on the full-range simulator system platform, the original model, and training use is reduced through an external severe accident simulator, thereby ensuring the normal simulation calculation effect and training use frequency of the original full-range simulator.

[0069] In order to implement the above embodiments, the present application also proposes a nuclear power plant data simulation device.

[0075] Furthermore, in a possible implementation of the embodiment of the present application, the acquisition module 301 is further configured to:

[0076] Collecting the first historical operation data of the full-range simulator and the second historical operation data of the power plant units according to a preset receiving frequency;

[0077] The first historical data and the second operating data are arranged in chronological order to serve as initial simulation data.

[0078] Furthermore, in a possible implementation of the embodiment of the present application, the screening module 302 is further configured to:

[0079] In the initial simulation data, the operating data of the severe accident stage is selected as the target data.

[0080] Based on the core outlet temperature, determine whether the nuclear power plant has entered the severe accident stage.

[0081] In response to the core outlet temperature being greater than or equal to a preset temperature, it is determined that the nuclear power plant enters a severe accident stage.

[0082] Furthermore, in a possible implementation of the embodiment of the present application, the simulation module 303 is further configured to:

[0083] Using a preset severe accident analysis program, the input data is updated in real time, wherein the input data is the data after the fault data is inserted into the target data.

[0084] In the initial simulation data, the operating data where the fault occurs is extracted as the fault data;

[0085] In response to triggering a fault event, the fault data is inserted into the target data using the fault interface.
