Description

A system for determining the operating status of a power plant based on the operating mode

[0001] The present invention relates to a system for determining the operating status of a power plant, and more specifically, to a system for determining the operating status of a power plant based on an operating mode.

[0002] Nuclear power plants ensure safe operation during operation by complying with the operating constraints of the technical operating guidelines, and the items to be monitored under these constraints change depending on the operating mode of the power plant. Here, there are a total of seven operating modes, ranging from No mode to No mode, based on 'output', 'reactivity', 'reactor coolant cryogenic tube temperature', and 'stud bolt fastening status'.

[0003] However, since the number of items to be monitored for driving restriction conditions is large and the items to be monitored change depending on the driving mode, there is a possibility of missing situations arising from driving restriction conditions when the driving mode is changed.

[0004] For example, if the operating restriction "one reactor building atmospheric particle and gas radiation monitor must be operational" applies only to operating modes 1, 2, 3, and 4 and not to other operating modes, and an operator declares a change from operating mode 5 to 4, but the monitor is inoperable, the operating restriction is not satisfied. If the relevant measures resulting from the non-satisfaction are not properly performed within the time limit, there is a possibility of violating the operating restriction, which could have a serious impact on the safety of the power plant.

[0005] Accurately determining the operating status of a power plant is essential for efficient operation and ensuring safety. Existing power plant operating status determination systems primarily focus on identifying operating modes based on the current state and contribute to maintaining optimal operating performance through real-time data collection and analysis. However, these systems have limitations in pre-testing and optimizing various operating conditions due to a lack of simulation capabilities, including virtual operating modes.

[0006] Furthermore, while nuclear power plants have an operation support system that notifies of changes in operating modes, there is no device that allows operators to preview a specific operating mode in advance.

[0007] The technical objective of the present invention to solve the aforementioned problems is to provide a system for determining the operating status of a power plant based on an operating mode, which allows an operator to use virtualization technology before entering a specific operating mode to check in advance whether operating restriction conditions are not satisfied.

[0008] However, the problem to be solved by the present invention is not limited thereto and may be expanded in various ways without departing from the spirit and scope of the present invention.

[0009] To achieve the above objectives, a system for determining the operating status of a power plant based on an operating mode according to one embodiment may include an operating mode determining device that determines the current operating mode of the power plant using status information for each device within the power plant, a power plant operating status determining device that determines the current operating status of the power plant based on the current operating mode, and an interface that provides the current operating status of the power plant to an operator.

[0010] The status information for each device within the above-mentioned power plant can be collected from the power plant information system through the data acquisition unit.

[0011] The above-described power plant operating status determination device includes an operating restriction condition list loading device, wherein the operating restriction condition list loading device retrieves a plurality of operating restriction condition lists required in the current operating mode from a first memory, and the plurality of operating restriction condition lists may be composed of a table matched with operating restriction condition information for each device within the power plant.

[0012] The above power plant operating status determination device can determine the current operating status of the power plant by determining whether all status information for each device within the power plant satisfies all operating restriction conditions for each device within the power plant that are included in the list of multiple operating restriction conditions required in the current operating mode.

[0013] The above user interface can provide the user with the current operating mode of the power plant and the determination result.

[0014] On the other hand, it may include a simulator that receives a virtual operating mode selected and entered by a user and derives virtual state information for each device within the power plant simulated in the environment of the virtual operating mode, a virtual device for determining the virtual operating state of the power plant based on the virtual state information for each device within the power plant, and a virtual operating mode interface that provides the virtual operating state of the power plant in the virtual operating mode to an operator.

[0015] The above simulator simulates by retrieving initial conditions corresponding to the virtual operating mode from the second memory, wherein the initial conditions may include state information of the device within the power plant.

[0016] The above-described power plant operating status determination virtual device retrieves a plurality of operating restriction condition lists required in the virtual operating mode from a second memory, wherein the plurality of operating restriction condition lists may be composed of a table matched with operating restriction condition information for each device within the power plant.

[0017] The above-described virtual device for determining the operating status of a power plant can determine the virtual operating status of the power plant in the virtual operating mode by determining whether all virtual status information for each device within the power plant satisfies all operating restriction conditions for each device within the power plant that are included in the list of multiple operating restriction conditions required in the virtual operating mode.

[0018] On the other hand, as a system for determining the current operating state of a power plant and the operating state of a power plant in a virtual operating mode, it includes a device for determining the current operating state of a power plant configured to determine the operating state of a power plant based on the current operating mode of the power plant, and a virtualization system configured to determine the virtual operating state of a power plant in a virtualization environment operating in a virtual operating mode input by a user, wherein the virtualization system can determine the virtual operating state of a power plant by determining whether the state information for each device within the power plant derived by a simulator based on the virtual operating mode satisfies the operating constraint conditions required in the virtual operating mode.

[0019] The current operating mode of the above power plant can be determined using current status information for each device within the power plant.

[0020] The above simulator can output simulated state information for each device within the power plant by simulating with the current state information for each device within the power plant, received through the power plant information system, as an initial condition.

[0021] The virtualization system can compare the current status information for each device within the power plant received through the power plant information system with the simulated status information for each device within the power plant output from the simulator in the virtual operation mode, or determine whether the operating constraints required in the virtual operation mode are satisfied, and provide the comparison result and the determination result to the user through the virtual operation mode interface.

[0022] The above comparison result can be determined by checking whether the current status information for each device within the power plant transmitted by the power plant information system falls within a certain ratio range of the simulated status information for each device within the power plant output by the simulator in the virtual operation mode.

[0023] The virtualization system includes a virtual driving mode interface, and the virtualization system receives the virtual driving mode through the virtual driving mode interface, and the user can operate a virtual device within the simulator through the virtual driving mode interface.

[0024] The disclosed technology may have the following effects. However, this does not mean that a specific embodiment must include all of the following effects or only the following effects; therefore, the scope of the rights of the disclosed technology should not be understood as being limited by this.

[0025] According to the system for determining the operating state of a power plant based on an operating mode according to the embodiments of the present invention described above, when an operator changes the operating mode of the power plant, the current operating state of the power plant can be verified against the operating restriction conditions required by the operating mode to which the operating state is changed, thereby eliminating risk factors that violate safe operation.

[0035] Hereinafter, preferred embodiments of the present invention will be described clearly and in detail with reference to the attached drawings so that a person skilled in the art can easily practice the present invention.

[0036] FIG. 1 is a block diagram of a system for determining the operating status of a power plant according to an embodiment of the present invention.

[0037] The power plant operating status determination system (100) illustrated in FIG. 1 may include a power plant current operating status determination device (110), and the power plant current operating status determination device (110) may include a data acquisition unit (170), an operating mode determination device (111), an operating restriction condition list loading device (112), a power plant operating status determination device (113), and a user interface (114).

[0038] The data acquisition unit (170) can acquire status information for each device within the power plant. Here, the status information for each device within the power plant may include the temperature of the RCS (Reactor Coolant System) low-temperature tube, output, rebound, presence or absence of the core, and whether the stud bolts are fastened.

[0039] The operating mode determination device (111) can determine the current operating mode of the power plant based on status information for each device within the power plant. Here, examples of operating modes may include power operation, startup, high-temperature standby, high-temperature shutdown, low-temperature shutdown, and nuclear fuel reloading.

[0040] The driving restriction condition list loading device (112) can load a list of driving restriction conditions required for each driving mode from the first memory (115). For example, in driving mode 1, it may include about 60 driving restriction conditions such as 3.1.1 to 3.9.2, and in driving mode 2, it may include about 50 driving restriction conditions such as 3.1.1 to 3.3.1.

[0041] The operation restriction condition list loading device (112) can retrieve a plurality of operation restriction condition lists required in the current operation mode from the first memory (115), and the plurality of operation restriction condition lists can be configured as a table matched with operation restriction condition information for each device within the power plant.

[0042] The power plant operating state determination device (113) can determine the current operating state of the power plant based on the current operating mode and the list of operating restriction conditions received from the operating mode determination device (111). Specifically, the current operating state of the power plant can be determined by determining whether all state information for each device within the power plant satisfies all of the operating restriction conditions for each device within the power plant that are included in the list of multiple operating restriction conditions required by the current mode. That is, the operating state can be classified into a state in which all state information for each device within the power plant satisfies all of the operating restriction conditions for each device within the power plant that are included in the list of multiple operating restriction conditions required by the current mode, and a state in which it does not.

[0043] The user interface (114) can provide the user (190) with a determination result regarding whether the current operating mode and current operating status of the power plant, that is, the status information of each device within the power plant, satisfies the operating restriction conditions required in the current operating mode.

[0044] Additionally, the user interface (114) can request current status information for each device within the power plant from the data acquisition unit (170).

[0045] FIG. 2 is a block diagram of a system for determining the operating status of a power plant according to another embodiment of the present invention.

[0046] The power plant operating status determination system (200) illustrated in FIG. 2 may include a virtualization system (210), and the virtualization system (210) may include a simulator (211), a virtual operating mode interface (212), a virtual device for determining the power plant operating status (213), and a virtual device for loading an operating restriction list (214).

[0047] The virtualization system (210) can basically simulate 7 driving modes.

[0048] The simulator (211) receives a virtual operating mode selected and input by the user (290) through the virtual operating mode interface (212), and simulates based on initial conditions corresponding to the virtual operating mode retrieved from the second memory (215) to derive a virtual simulated operating state for each device within the power plant and transmits it to the virtual device (213) for determining the operating state of the power plant. Here, the initial conditions may include operating variables of the devices within the power plant.

[0049] The virtual device (214) for loading the list of operating restrictions loads a plurality of lists of operating restrictions required in a virtual operating mode from the second memory (215) and transmits them to the virtual device (213) for determining the operating state of a power plant. For example, operating mode 1 includes operating restriction A, and the detailed condition is that the thermal output is 20% or more, and operating mode 4 includes operating restriction B, and the detailed condition is that at least one of the four valves must be kept open.

[0050] The virtual device (213) for determining the operating state of a power plant can determine the operating state of the power plant in a virtual operating mode based on virtual state information for each device within the power plant transmitted from the simulator (211) and a list of operating restriction conditions corresponding to the virtual operating mode. Specifically, the operating state in the virtual operating mode can be determined by checking whether the virtual state information for each device within the power plant transmitted from the simulator (211) satisfies all operating restriction conditions required in the virtual operating mode.

[0051] When the user (190) enters virtual operation mode 1, the operation restriction list loading virtual device (214) presents the thermal output item, which is a detailed condition of operation restriction A, and the power plant operation state judgment virtual device (213) can determine whether the virtual simulated operation state for each device within the power plant derived by the simulator (211) satisfies operation restriction A.

[0052] When the user (190) enters virtual driving mode 4, the simulator (211) provides four valve states and can determine whether there is an abnormality through the user's (190) virtual operation of the four valve states.

[0053] The virtual operation mode interface (212) can provide the user (190) with a determination result regarding whether the status information of each device within the power plant derived by the simulator (211) satisfies the operation restriction conditions required in the virtual operation mode, such as the power plant virtual operation mode and virtual operation state.

[0058] The virtual device (213) for determining the operating status of the power plant can receive current status information for each device within the power plant from the data acquisition unit (180).

[0059] The virtual device (213) for determining the operating status of a power plant can compare the current status information for each device within the power plant received through the data acquisition unit (170) with the simulated status information for each device within the power plant output from the simulator (221) in the virtual operating mode, or determine whether the simulated status information for each device within the power plant output from the simulator (221) in the virtual operating mode satisfies the operating restriction conditions required in the virtual operating mode. The virtual device (213) for determining the operating status of a power plant can provide the comparison result and the determination result to the user through the virtual operating mode interface (212). Here, the comparison result can be determined by checking whether the current status information for each device within the power plant transmitted by the power plant information system (180) falls within a certain ratio range of the simulated status information for each device within the power plant output from the simulator (221) in the virtual operating mode.

[0060] The user (390) can receive a determination result through the user interface (114) regarding whether the current operating mode and current operating status of the power plant, that is, the status information of each device within the power plant, satisfies the operating restriction conditions required in the current operating mode.

[0061] Additionally, the user (390) may request a virtual operation mode to enter in advance through the virtual operation mode interface (212), and receive information through the virtual operation mode interface (212) regarding whether the status information of each device in the current power plant satisfies the operation restriction conditions required by the virtual operation mode when entering the virtual operation mode from the current operation mode.
