[0052] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0053] The cold source abnormality processing method of a nuclear power plant provided in the embodiment of the present application can be applied in the following aspects: Figure 1 In the application environment, Figure 1The invention is a system diagram of a cold source circulation system of a nuclear power plant, wherein the cold source circulation system of the nuclear power plant includes a first cold source system (CFIA, A cold source) and a second cold source system (CFIB, B cold source), wherein the first cold source system includes a water inlet channel, a coarse filter screen 004GG, a sodium hypochlorite injection pipeline, a valve 302VE, a water gate 002BU, a trash rack 012DG, a valve 304VE, a water gate 004BU, a trash rack 014DG, a rotating filter screen 032TF (hereinafter referred to as the first filter screen), a motor 002MO, and an electric motor. The second cold source system includes an inlet channel, on which are provided a coarse filter screen 001GG, a coarse filter screen 003GG, a sodium hypochlorite injection pipeline, a valve 301VE, a sluice gate 001BU, a trash rack 011DG, a valve 303VE, a sluice gate 003BU, a trash rack 013DG, a rotary filter screen 031TF (referred to as the second filter screen in this application), a motor 001MO, a motor 003 / 005MO and a motor 007MO, etc. The above motors are also driving devices in the cold source system.

[0054] It should be noted that Figure 1 The system shown here is only an exemplary description and does not limit the present application. The inventor has found that the cooling water (such as seawater) used in the three-circuit of a nuclear power plant is easily blocked by shrimps or other obstacles in the sea, which will increase the pressure difference of the filter screen in the supercooling source circulation system, thereby causing the power of the related driving equipment of the cold source system to decrease. The existing equipment power is only displayed in a simple data display in real time. In actual scenarios, different cold sources correspond to different nuclear power units under different circumstances. It is not easy for operators to judge whether the cold source is abnormal in many data. To solve the above problems, the present embodiment provides a cold source abnormality processing method for a nuclear power plant, as described below.

[0055] In one embodiment, if Figure 2 As shown, a method for handling cold source abnormality in a nuclear power plant is provided, comprising the following steps:

[0056] S10: Rendering a cold source abnormality monitoring screen, wherein the cold source abnormality monitoring screen includes a monitoring table, wherein a first horizontal column item of the monitoring table is rendered with a pressure difference value range of a first filter of a first cold source system, and a first vertical column item of the monitoring table is rendered with a pressure difference value range of a second filter of a second cold source system, wherein the first cold source system and the second cold source system are cold source systems arranged in a cold source circulation system of a nuclear power plant, and the first horizontal column item includes a plurality of sub-horizontal column items, and the first vertical column item includes a plurality of sub-vertical column items.

[0057] In an embodiment of the present application, the pressure difference value range of the first filter screen of the first cold source system (CFIA) and the pressure difference value range of the first filter screen of the second cold source system (CFIB) are pre-set, wherein the first cold source system and the second cold source system are cold source systems provided in the cold source circulation system of a nuclear power plant. Exemplarily, the pressure difference value range of the first filter screen may include: less than high 1, high 1, high 2, high 3 and high 4; similarly, the pressure difference value range of the second filter screen may include: less than high 1, high 1, high 2, high 3 and high 4, wherein high 1 to high 4 reflect a trend of gradually increasing pressure difference of the filter screen. In an embodiment of the present application, the above-mentioned monitoring table will be rendered in the cold source abnormality monitoring screen based on the set pressure difference value range.

[0058] The rendered monitoring table is as follows Figure 3 As shown, Figure 3 The figure is a display diagram of the monitoring table of the cold source abnormality monitoring screen, including the first horizontal column item, the first vertical column item, other vertical column items and other horizontal column items; wherein, the first horizontal column item includes multiple sub-horizontal column items, each sub-horizontal column item corresponds to a pressure difference value range of the first filter, and the first vertical column item includes multiple sub-vertical column items, each sub-vertical column item corresponds to a pressure difference value range of the second filter.

[0059] S20: collecting the real-time differential pressure of the first filter screen, and collecting the real-time differential pressure of the second filter screen.

[0060] S30: Determine a corresponding cold source processing logic according to the real-time pressure difference of the first filter screen and the real-time pressure difference of the second filter screen, wherein the cold source processing logic is used to indicate processing and response items for the current cold source situation.

[0061] In the embodiment of the present invention, the real-time differential pressure of the first filter screen and the real-time differential pressure of the second filter screen are collected in real time. The above-mentioned real-time differential pressure can be obtained by means of a sensor. After collecting the real-time differential pressure of the first filter screen and the real-time differential pressure of the second filter screen, the real-time differential pressure of each filter screen in the current first cold source system and the second cold source system can be known. Taking the first filter screen as an example, if the real-time differential pressure of the first filter screen is too high, it means that the current first filter screen is very likely to be blocked, that is, the real-time differential pressure of the first filter screen reflects the blocking of the first filter screen; the same is true for the second filter screen, therefore, the cold source processing logic corresponding to the real-time differential pressure of the current first filter screen and the second filter screen can be determined based on this situation, wherein the cold source processing logic is used to indicate the processing and response matters of the current cold source situation.

[0062] It should be noted that based on the real-time pressure difference of the first filter and the real-time pressure difference of the second filter, the nuclear power unit will respond to the current situation to execute the subsequent operating status, that is, the operating status of different nuclear power units under different cold sources will be different, and the difference in this operating status is reflected in the subsequent upper cold source processing logic. The cold source processing logic is used to indicate the processing and response matters of the current cold source situation, reflecting the status trend of the nuclear power unit.

[0063] Exemplarily, the corresponding cold source processing logic may be, based on the corresponding pressure difference, reducing the operating power of certain driving devices, increasing the operating power of certain driving devices, manually shutting down the reactor or performing a hot shutdown, etc., without specific limitation and no further examples will be given.

[0064] S40: Determine a first sub-column item of a pressure difference value range where the real-time pressure difference of the first filter screen is located, and determine a first sub-column item of a pressure difference value range where the real-time pressure difference of the second filter screen is located.

[0065] S50: Rendering the corresponding cold source processing logic in the intersection item of the first sub-horizontal column item and the first sub-vertical column item.

[0066] For step S40 and step S50, after determining the corresponding cold source processing logic according to the real-time pressure difference of the first filter and the real-time pressure difference of the second filter, the embodiment of the present application will further determine the first sub-horizontal column item of the pressure difference value range where the real-time pressure difference of the first filter is located, and determine the first sub-vertical column item of the pressure difference value range where the real-time pressure difference of the second filter is located, and render the corresponding cold source processing logic in the intersection item of the first sub-horizontal column item and the second sub-vertical column item.

[0067] like Figure 4 As shown, assuming that the current pressure difference value range of the real-time pressure difference of the first filter is high 4, it is determined that the pressure difference value range of the real-time pressure difference of the second filter is also high 4, and the schematic diagram of the intersection of the two real-time corresponding sub-column items is as shown in Figure 4 As shown, the corresponding cold source processing logic is "manual shutdown". Figure 4 The corresponding cold source processing logic "manual shutdown" is directly rendered in the intersecting project shown.

[0068] In one embodiment, when rendering a specific cold source processing logic, an explicit color can be rendered, wherein the explicit color here refers to a color that can distinguish the above-mentioned intersection item from other intersection items. In step S10, that is, in the intersection item of the first sub-horizontal column item and the first sub-vertical column item, the corresponding cold source processing logic is rendered, including: in the intersection item, a text description of the corresponding cold source processing logic is rendered, and a preset color is rendered in the intersection item.

[0069] In this embodiment, continue as Figure 4 As shown in , the text description "manual shutdown" of the cold source processing logic is directly rendered in the intersection item, and a preset color is rendered in the intersection item. After rendering the preset color, the text description of the cold source processing logic must be clearly visible, wherein the preset color can be blue, red, green, etc. In some embodiments, rendering the preset color in the intersection item refers to the background color of the intersection item. It can be seen that in this way, the operator can quickly notice the pressure difference of the current cold source system and the corresponding cold source processing logic, so that the operator can pay attention to or respond to the processing in time.

[0070] In some embodiments, different color levels can be used for rendering and distinguishing according to the deterioration of the real-time pressure difference of the first filter and the real-time pressure difference of the second filter. For example, six colors, white, yellow, blue, red, purple and green, represent the degree of deterioration of the real-time pressure difference in sequence, and are used for rendering in the above-mentioned intersection items to reflect different degrees of pressure difference deterioration.

[0071] In one embodiment, if Figure 5 As shown, in step S30, that is, determining the corresponding cold source processing logic according to the real-time pressure difference of the first filter screen and the real-time pressure difference of the second filter screen, specifically includes the following steps:

[0072] S31: collecting the working power of the driving device of the first cooling source system; collecting the working power of the driving device of the first cooling source system;

[0073] S32: Determine the corresponding cold source processing logic according to the real-time pressure difference of the first filter screen, the real-time pressure difference of the second filter screen, the operating power of the driving device of the first cold source system, and the operating power of the driving device of the second cold source system.

[0074] In this embodiment, the working power of the driving device of the first cooling source system is also collected in real time, such as Figure 1As shown, the relevant driving devices in the first cold source system include the motor in the first cold source system. Similarly, the relevant driving devices in the second cold source system include the motor in the second cold source system. It can be understood that the pressure difference of the first filter and / or the second filter will affect the working power of some driving devices in the cold source system. In order to accurately and in real time know the working conditions of the relevant driving devices, the embodiment of the present application will further collect the working power of the driving devices of the first cold source system and the working power of the driving devices of the first cold source system. And according to the real-time pressure difference of the first filter, the real-time pressure difference of the second filter, the working power of the driving devices of the first cold source system and the working power of the driving devices of the second cold source system, the corresponding cold source processing logic is determined.

[0075] In this embodiment, when determining the corresponding cold source processing logic, not only the real-time pressure difference of the first filter and the real-time pressure difference of the second filter are used, but also the working power of the driving equipment of the first cold source system and the working power of the driving equipment of the second cold source system are further referred to to determine the most suitable cold source processing logic or a more specific cold source processing logic, such as reducing the working power of certain driving equipment to a specific number of watts, increasing the working power of certain driving equipment to a specific number of watts, etc., without specific limitation, which can make the operating personnel more intuitive and clear about the status trend of the nuclear power unit.

[0076] In some embodiments, after step S31, that is, collecting the working power of the driving device of the first cold source system, after collecting the working power of the driving device of the first cold source system, the method further includes the following steps:

[0077] S33: comparing the working power of the driving device of the first cold source system with the corresponding first alarm threshold to determine the working state of the driving device of the first cold source system;

[0078] S34: comparing the operating power of the driving device of the second cold source system with the corresponding second alarm threshold to determine the operating state of the driving device of the second cold source system;

[0079] S35: In the cold source abnormality monitoring picture, the working status of the driving device of the first cold source system and the working status of the driving device of the second cold source system are respectively rendered.

[0080] In this embodiment, if Figure 5As shown, in the embodiment of the present application, corresponding alarm thresholds can be set for different driving devices according to the different states of the current first cold source system (CFIA) and the second cold source system (CFIB). Furthermore, the working power of the corresponding driving device is compared with the corresponding alarm threshold, so that the working state of the driving device is determined according to the comparison result, and the rendering is displayed according to the working state.

[0081] Specifically, the working status screen of the driving device of CFIA and the working status screen of the driving device of CFIB are rendered respectively, and are used to render and display the working status of the driving device of CFIA and the working status of the driving device of CFIB respectively.

[0082] In some embodiments, when the working power of the driving device of the first cold source system is higher than the corresponding first alarm threshold, the working state of the driving device of the first cold source system is determined to be abnormal; when the working power of the driving device of the first cold source system is lower than the corresponding first alarm threshold, the working state of the driving device of the first cold source system is determined to be normal; similarly, when the working power of the driving device of the second cold source system is higher than the corresponding second alarm threshold, the working state of the driving device of the second cold source system is determined to be abnormal; when the working power of the driving device of the second cold source system is lower than the corresponding second alarm threshold, the working state of the driving device of the second cold source system is determined to be normal. When in normal state, the corresponding driving device can be rendered as "normal" in the rendering of the cold source abnormality monitoring screen, otherwise the corresponding driving device can be rendered as "abnormal".

[0083] In some embodiments, after step S35, that is, after the working status of the driving device of the first cooling source system and the working status of the driving device of the second cooling source system are rendered respectively, the method further includes the following steps:

[0084] S36: when the working state of the driving device of the first cold source system is abnormal, a corresponding warning sound is issued according to the degree of abnormality of the driving device of the first cold source system;

[0085] and / or;

[0086] S37: When the working state of the driving device of the second cold source system is abnormal, a corresponding warning sound is issued according to the degree of abnormality of the driving device of the second cold source system.

[0087] In this embodiment, different warning sounds may be set for different working states of the driving devices so that the operator can respond in time.

[0088] In some embodiments, other important information of the first cold source system, such as equipment information or warning information of other related equipment, can be rendered in real time in the working status screen of the driving device of CFIA, and important information of the second cold source system, such as equipment information or warning information of other related equipment, can be rendered in real time in the working status screen of the driving device of CFIB, without specific limitation.

[0089] In some embodiments, the method further comprises the steps of:

[0090] S60: Determine the cold source processing logic corresponding to the target intersection item where other sub-column items intersect with other sub-column items;

[0091] S70: Rendering the cold source processing logic corresponding to the target intersection item in the target intersection item.

[0092] The other sub-column items are other sub-column items in the first column item except the first sub-column item, and the other sub-column items are other sub-column items in the first column item except the first sub-column item. In the embodiment of the present application, in addition to determining the cold source processing logic corresponding to the intersection item of the first sub-column item and the first sub-column item, the cold source processing logic corresponding to the target intersection item where other sub-column items intersect with other sub-column items is also determined.

[0093] like Figure 6 As shown, the item where a1 is located is the intersection item of the first sub-column item and the first sub-column item, a1 represents the cold source processing logic corresponding to the item, and other blank items represent the target intersection items where other sub-column items intersect with other sub-column items. It can be seen that the target intersection items may include multiple, exemplary, Figure 6 There are also 25 target intersection items included.

[0094] In this embodiment, the cold source processing logic corresponding to the target intersection item is further rendered in the 25 target intersection items, such as Figure 6 The horizontal item "<High 1" in the column and the intersection item b1 where the vertical item "<High 1" is located are one of the target intersection items, and the corresponding cold source processing will be rendered in the intersection item b1. It should be noted that for the convenience of explanation, Figure 6 This is just a schematic diagram. Except for the intersection item b1, other intersection items will also render the corresponding specific text description of the cold source processing logic. Unlike the intersection item a1, the intersection item a1 will render a preset color to distinguish and display the current real-time pressure difference of the cold source system and the cold source processing logic.

[0095] It can be seen from the above embodiments that in the embodiments of the present application, the state trend of the nuclear power unit under different conditions of the cold source system is judged through the cold source abnormality monitoring screen, and the cold source deterioration level is distinguished by different colors and / or sounds, and the important information of the equipment of the first cold source system and the second cold source system can be displayed in a centralized manner, which can provide the operator with cold source information and the judgment of the direction of the nuclear power unit quickly and accurately, greatly shorten the operator's cold source judgment intervention response time, reduce the misjudgment rate or missed judgment of the cold source risk caused by human factors, and improve the automatic early warning of cold source abnormalities, thereby improving the efficiency of handling cold source abnormalities, improving the stability of unit operation, and realizing the improvement of the economic efficiency of nuclear power plant operation, and it is of great significance to the construction of smart nuclear power plants.

[0096] It should be understood that the size of the serial numbers of the steps in the above embodiments does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present application.

[0097] In one embodiment, a cold source abnormality processing device for a nuclear power plant is provided, and the cold source abnormality processing device for a nuclear power plant corresponds one-to-one to the cold source abnormality processing method for a nuclear power plant in the above embodiment.
