Description

Technical Field

[0001] This invention relates to the field of nuclear power technology, and in particular to a control device and method for a high-temperature gas-cooled reactor nuclear power plant. Background Technology

[0002] Currently, typical high-temperature gas-cooled reactor (HTGR) nuclear power plants have relatively small single-reactor power outputs. Therefore, their application in nuclear power generation requires a multi-reactor-one-engine configuration. For example, the HTGR demonstration project currently under commissioning in China uses a dual-reactor-one-engine model. In this multi-reactor-one-engine mode, the main control room is shared by all reactors, and each reactor contains a large number of similar devices. This makes it extremely easy to operate in the wrong bay during operation, potentially leading to unplanned shutdowns, industrial safety accidents, and other serious consequences. Therefore, preventing incorrect bay operation in a shared main control room of a HTGR nuclear power plant is a crucial issue that urgently needs to be addressed. Summary of the Invention

[0003] The present invention aims to at least partially solve one of the technical problems in the related art.

[0004] To this end, a first aspect of the present invention provides a control device for a high-temperature gas-cooled reactor nuclear power plant, comprising at least two controllers for controlling different reactors in the high-temperature gas-cooled reactor nuclear power plant; wherein the at least two controllers include: a first controller that controls only a single reactor, and / or a second controller that controls at least two reactors; the first controller is configured to obtain user account information in response to a user input operation, and, if it is determined based on the user account information that the user has control authority over the single reactor, allow control of the single reactor; the second controller is configured to determine the target reactor to be unlocked from the at least two reactors in response to the completion of the unlocking process, and allow control of the target reactor.

[0005] In one embodiment of the present invention, the second controller is configured to display an unlock control and selection controls corresponding to the at least two reactors on the interface; in response to a trigger operation performed on the unlock control and a trigger operation performed on one of the selection controls corresponding to the at least two reactors, determine that the unlocking process has been completed; in response to the completion of the unlocking process, designate the reactor corresponding to the selection control that performed the trigger operation as the target reactor, and allow control of the target reactor based on user instructions.

[0006] In one embodiment of the present invention, the second controller is further configured to adjust the background of the interface of the second controller to the color corresponding to the target reactor according to the correspondence between the reactor and the color.

[0007] In one embodiment of the present invention, there is a correspondence between the reactors and colors in the high-temperature gas-cooled reactor nuclear power plant; the background color of the interface of the first controller is the color corresponding to the single reactor being controlled.

[0008] In one embodiment of the present invention, the second controller is further configured to adjust the layout of elements in the interface of the second controller to the interface element layout corresponding to the target reactor according to the correspondence between the reactor and the interface element layout.

[0009] In one embodiment of the present invention, there is a correspondence between the reactor and the interface element layout in the high-temperature gas-cooled reactor nuclear power plant; the layout of elements in the interface of the first controller is the interface element layout corresponding to the single reactor being controlled.

[0010] This invention proposes a control device for a high-temperature gas-cooled reactor (HTGR) nuclear power plant. The device includes at least two controllers for controlling different reactors in the HTGR nuclear power plant. Each controller includes a first controller that controls only a single reactor, and / or a second controller that controls at least two reactors. The first controller is configured to acquire user account information in response to user input, and if the user account information determines that they have control authority over a single reactor, allow control of that single reactor. The second controller is configured to determine the target reactor to be unlocked from the at least two reactors in response to the completion of the unlocking process, and allow control of the target reactor. Therefore, by functionally designing the controllers for different reactors in the HTGR nuclear power plant, the probability of operating the wrong interval when operating different reactor equipment is reduced, and the level of protection against human error in new units is improved.

[0011] A second aspect of the present invention provides a control method for a high-temperature gas-cooled reactor (HTGR) nuclear power plant, the HTGR nuclear power plant including at least two controllers for controlling different reactors in the HTGR nuclear power plant; the at least two controllers include: a first controller that controls only a single reactor, and / or a second controller that controls at least two reactors; the method includes: in response to a user input operation performed on the first controller, obtaining user account information, and allowing control of the single reactor if it is determined based on the user account information that the user has control authority over the single reactor; in response to the completion of an unlocking process performed on the second controller, determining a target reactor to be unlocked from the at least two reactors, and allowing control of the target reactor.

[0012] In one embodiment of the present invention, the step of determining the target reactor to be unlocked from the at least two reactors and allowing control of the target reactor in response to the completion of the unlocking process executed on the second controller includes: displaying an unlocking control and selection controls corresponding to the at least two reactors on the interface of the second controller; determining that the unlocking process has been completed in response to a trigger operation executed on the unlocking control and a trigger operation executed on one of the selection controls corresponding to the at least two reactors; and, in response to the completion of the unlocking process, designating the reactor corresponding to the selection control that executed the trigger operation as the target reactor and allowing control of the target reactor based on user instructions.

[0014] In one embodiment of the present invention, the method further includes: when there is a correspondence between the reactor and the color in the high-temperature gas-cooled reactor nuclear power plant, configuring the background color of the interface of the first controller to the color corresponding to the single reactor being controlled; and / or, when there is a correspondence between the reactor and the layout of interface elements in the high-temperature gas-cooled reactor nuclear power plant, configuring the layout of elements in the interface of the first controller to the layout of interface elements corresponding to the single reactor being controlled.

[0015] This invention proposes a control method for a high-temperature gas-cooled reactor (HTGR) nuclear power plant. The HTGR nuclear power plant includes at least two controllers for controlling different reactors within the plant. The at least two controllers include: a first controller that controls only a single reactor, and / or a second controller that controls at least two reactors.

Therefore, based on the functional design of the controllers for different reactors in the HTGR nuclear power plant, the probability of operating the wrong interval when operating different reactor equipment is reduced, and the level of protection against human error in new units is improved.

[0016] A third aspect of the present invention provides a non-transitory computer-readable storage medium storing computer instructions for causing the computer to execute the control method of the high-temperature gas-cooled reactor nuclear power plant of the present invention.

[0017] A fourth aspect of the present invention provides a computer program product that, when executed by an instruction processor, implements the control method for a high-temperature gas-cooled reactor nuclear power plant according to the embodiments of the present invention.

[0018] Other effects of the above-mentioned alternative methods will be described below in conjunction with specific embodiments. Attached Figure Description

[0019] The above and / or additional aspects and advantages of the present invention will become apparent and readily understood from the following description of the embodiments taken in conjunction with the accompanying drawings, wherein:

[0020] Figure 1 This is a schematic diagram of the structure of a control device for a high-temperature gas-cooled reactor nuclear power plant provided in an embodiment of the present invention. Detailed Implementation

[0021] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0022] The control apparatus and method for a high-temperature gas-cooled reactor nuclear power plant according to embodiments of the present invention are described below with reference to the accompanying drawings.

[0023] Figure 1 This is a schematic diagram of the structure of a control device for a high-temperature gas-cooled reactor nuclear power plant provided in an embodiment of the present invention.

[0024] like Figure 1 As shown, the control device of the high-temperature gas-cooled reactor nuclear power plant can have at least two controllers for controlling different reactors in the high-temperature gas-cooled reactor nuclear power plant, wherein the at least two controllers include: a first controller 101 that controls only a single reactor, and / or a second controller 102 that controls at least two reactors.

[0025] In some embodiments, the first controller 101 is configured to obtain user account information in response to a user input operation, and, if it is determined from the user account information that the controller has control authority over a single reactor, allow control of that single reactor.

[0026] In some embodiments, user account information is obtained based on user input operations, and the user operation information is input into the controller system corresponding to the reactor in the high-temperature gas-cooled reactor nuclear power plant to enter the controller system. If the user account information determines that they have control authority over a single reactor, then control of the single reactor is permitted.

[0027] Among them, such as Figure 1 As shown, the first controller 101 may include a first on control 1011, a first off control 1012, and a first controller control module 1013.

[0028] The first controller control module 1013 can be any one of the reactor equipment, and this embodiment does not specifically limit it.

[0029] Specifically, after obtaining user account information in response to user input operations and determining that the user has control authority over a single reactor based on the user account information, the first controller control module 1013 is controlled according to the user's operation instructions, and the first controller control module 1013 is started and stopped according to the first start control 1011 and the second stop control 1012.

[0030] For example, when the first controller control module 1013 is a control valve, the first opening control 1011 and the first closing control 1012 control the opening and closing of the control valve.

[0031] The second controller 102 is configured to, in response to the completion of the unlocking process, identify the target reactor to be unlocked from at least two reactors and allow control of the target reactor.

[0032] Among them, such as Figure 1 As shown, the second controller 102 may include a second opening control 1021, a second closing control 1022, an unlocking control 1023, a selection control 1024, and a second controller control module 1025.

[0033] The second controller control module 1025 can be any one of the target reactor devices, and this embodiment does not specifically limit it.

[0034] Specifically, after obtaining user account information in response to user input, the system enters the display interface of the second controller 102. In response to the user clicking the unlock control 1023, until the unlocking process is completed, the target reactor to be unlocked is determined from at least two selection controls 1024, and control of the target reactor is allowed.

[0035] For example, such as Figure 1As shown, when there are two selection controls 1024, namely reactor No. 1 and reactor No. 2, the user first clicks the unlock control 1023 to enter the selection interface of the selection control 1024. After selecting the target reactor, the user controls the second controller control module 1025 according to the operation instructions. The user controls the start and stop of the second controller control module 1025 according to the second start control 1021 and the second stop control 1022.

[0036] For example, when the second controller control module 1025 is a control valve, the second opening control 1021 and the second closing control 1022 control the opening and closing of the control valve.

[0037] In other embodiments, the second controller 102 is configured to display an unlock control 1023 and selection controls 1024 corresponding to at least two reactors on the interface; in response to a trigger operation performed on the unlock control 1023 and a trigger operation performed on one of the selection controls 1024 corresponding to at least two reactors, determine that the unlocking process has been completed; in response to the completion of the unlocking process, designate the reactor corresponding to the selection control 1024 that has performed the trigger operation as the target reactor, and allow control of the target reactor based on user instructions.

[0038] In addition, in some embodiments, the second controller 102 is also used to adjust the background of the interface of the second controller 102 to the color corresponding to the target reactor according to the correspondence between the reactor and the color, thereby reminding the user and reducing the probability of going to the wrong interval when operating different reactor equipment.

[0039] Specifically, the correspondence between reactors and colors in a high-temperature gas-cooled reactor nuclear power plant can be determined based on the standard unit colors of the units in the actual application scenario, so as to adjust the interface background of the second controller 102 to the color corresponding to the target reactor. However, this is not limited to this, and this embodiment does not make any specific limitations on it.

[0040] In other embodiments, there is a correspondence between the reactors and colors in a high-temperature gas-cooled reactor nuclear power plant, wherein the background color of the interface of the first controller 101 is the color corresponding to the individual reactor it controls.

[0041] For example, reactors can be color-coded according to their individual characteristics. If a single reactor is yellow, the background color of the interface of the first controller 101 can be adjusted to yellow to form a corresponding control relationship with the single reactor, thereby improving the ability to identify the single reactor and improving the accuracy of reactor operation.

[0042] In some embodiments, the second controller 102 is further configured to adjust the layout of elements in the interface of the second controller 102 to the layout of interface elements corresponding to the target reactor based on the correspondence between the reactor and the interface element layout.

[0043] The correspondence between reactors and interface element layouts can be the same as the correspondence between reactors and colors. That is, the same color is used to mark reactors, interface element layouts, and controllers, thereby maximizing the prompts to users and avoiding mistakes when operating different reactor devices.

[0044] In other embodiments, there is a correspondence between the reactor and the interface element layout in the high-temperature gas-cooled reactor nuclear power plant. Specifically, the layout of elements in the interface of the first controller 101 is the interface element layout corresponding to the single reactor being controlled, thereby improving the identification capability of a single reactor and reducing the probability of human error.

[0045] In summary, this invention proposes a control device for a high-temperature gas-cooled reactor (HTGR) nuclear power plant, comprising at least two controllers for controlling different reactors within the HTGR nuclear power plant. Each controller includes a first controller that controls only a single reactor, and / or a second controller that controls at least two reactors. The first controller is configured to acquire user account information in response to user input, and, if the user account information determines that they have control authority over a single reactor, allow control of that single reactor. The second controller is configured to determine the target reactor to be unlocked from the at least two reactors upon completion of the unlocking process, and allow control of the target reactor. Therefore, by functionally designing the controllers for different reactors within the HTGR nuclear power plant, the probability of operating the wrong interval when operating different reactor equipment is reduced, and the level of protection against human error in new units is improved.

[0046] In addition, to clearly describe the control of the high-temperature gas-cooled reactor nuclear power plant of this application, embodiments of the present invention also provide a control method for a high-temperature gas-cooled reactor nuclear power plant, wherein the high-temperature gas-cooled reactor nuclear power plant includes at least two controllers for controlling different reactors in the high-temperature gas-cooled reactor nuclear power plant; the at least two controllers include: a first controller that controls only a single reactor, and / or a second controller that controls at least two reactors.

[0047] The method includes: in response to a user input operation performed on a first controller, obtaining user account information, and allowing control of a single reactor if the user account information determines that the user has control authority over a single reactor; in response to the completion of an unlocking process performed on a second controller, determining the target reactor to be unlocked from at least two reactors, and allowing control of the target reactor. This reduces the probability of operating the wrong interval when operating different reactor equipment, and improves the level of protection against human error in new units, based on the functional design of controllers for different reactors in a high-temperature gas-cooled reactor nuclear power plant.

[0048] One implementation of determining the target reactor to be unlocked from at least two reactors in response to the completion of the unlocking process executed on the second controller, and allowing control of the target reactor, may involve displaying an unlocking control and selection controls corresponding to at least two reactors on the interface of the second controller. In response to a trigger operation executed on the unlocking control and a trigger operation executed on one of the selection controls corresponding to at least two reactors, the unlocking process is determined to be completed. In response to the completion of the unlocking process, the reactor corresponding to the selection control that executed the trigger operation is taken as the target reactor, and control of the target reactor is allowed based on user instructions, thereby achieving precise selection of controllers for different reactors in a high-temperature gas-cooled reactor nuclear power plant.

[0049] Understandably, in order to effectively improve the level of human error prevention in a multi-reactor shared control room, greatly reduce the probability of going to the wrong interval, and reduce the occurrence of human-caused events, this application, on the one hand, adjusts the background of the second controller interface to the color corresponding to the target reactor based on the correspondence between the reactor and the color; and / or, based on the correspondence between the reactor and the layout of interface elements, adjusts the layout of the elements in the second controller interface to the layout of the interface elements corresponding to the target reactor, so as to remind the operating users of the multi-reactor shared control room with the page layout.

[0050] On the other hand, in the case where there is a correspondence between the reactor and the color in a high-temperature gas-cooled reactor nuclear power plant, the background color of the interface of the first controller is configured to the color corresponding to the single reactor being controlled; and / or, in the case where there is a correspondence between the reactor and the layout of interface elements in a high-temperature gas-cooled reactor nuclear power plant, the layout of the elements in the interface of the first controller is configured to the layout of the interface elements corresponding to the single reactor being controlled, so as to use color to remind the operating users of the multi-reactor shared main control room.
