[0065] The prior art often relies on the personal experience of relevant professionals to arrange equipment during the construction of a nuclear power plant overhaul project group, which requires a large amount of manual calculation, consumes time and effort, and is extremely inefficient, and is prone to errors due to personal negligence, poor accuracy, and difficult to meet the actual requirements of the nuclear power plant overhaul project group construction.

[0066] Therefore, the embodiments of the present application provide a nuclear power plant overhaul project group construction simulation method, device, computer readable storage medium and electronic equipment to solve the problems of low efficiency and poor accuracy in the prior art.

[0067] In the embodiments of the present application, the equipment layout position can be optimized and solved based on multiple objective functions, and simulated and displayed in an electronic sand table. The entire processing process does not require human intervention, and is free from reliance on the personal experience of relevant professionals, effectively improving efficiency, avoiding errors due to personal negligence, and improving accuracy, and better meeting the actual requirements of the nuclear power plant overhaul project group construction.

[0068] The execution subject of the embodiments of the present application can be an electronic device, which can include but is not limited to desktop computers, notebooks, palmtop computers, and server computing devices.

[0069] Please refer to Figure 1 An embodiment of a nuclear power plant overhaul project group construction simulation method in the embodiments of the present application can include:

[0070] Step S101, determining a set of equipment to be arranged in the construction of a nuclear power plant overhaul project group.

[0071] The set of equipment can include more than one device, which can include but is not limited to low-pressure cylinder equipment, generator equipment, and speed regulation equipment, and the number and type of equipment in the set of equipment are not limited in the embodiments of the present application.

[0072] In step S102, based on the space utilization of the device set, the barycenter offset and the bearing capacity constraint, a plurality of objective functions for the layout of the device set are respectively determined.

[0073] In the embodiments of the present application, the plurality of objective functions for the layout of the device set can include but are not limited to a first objective function, a second objective function and a third objective function, etc. The first objective function is a function with the optimization target of maximizing the space utilization of the device set, the second objective function is a function with the optimization target of minimizing the barycenter offset of the device set, and the third objective function is a function with the optimization target of ensuring that the bearing capacity of the device set does not exceed the preset maximum bearing capacity.

[0074] Suppose that the number of devices in the device set to be laid out is N, and the position of each device can be expressed in the form of the following formula:

[0075] X = {x1, x2, …, xN} N}

[0076] wherein, is the coordinate of the i-th device in the device set in the D-dimensional space, 1≤i≤N, D is the spatial dimension of the coordinate, D is 2, that is, the two-dimensional spatial coordinate of the device, and D is 3, that is, the three-dimensional spatial coordinate of the device.

[0077] In the process of determining the first objective function for the layout of the device set, the floor area of each device in the device set can be determined first. Then, the total floor area of the device set can be determined according to the floor area of each device in the device set. Finally, the first objective function for the layout of the device set can be determined according to the total floor area of the device set, as shown in the following formula:

[0078]

[0079] wherein, A i is the floor area of the i-th device in the device set, f1(X) is the first objective function for the layout of the device set, and through the first objective function, the floor area can be reduced as much as possible to improve the space utilization.

[0080] In the process of determining the second objective function for the layout of the device set, the positions of each device in the device set can be first determined for mean calculation to obtain the barycenter position of the device set. Then, the barycenter offset of the device set can be determined according to the barycenter position of the device set and the geometric center position of the preset planning area. Finally, the second objective function for the layout of the device set can be determined according to the barycenter offset of the device set, as shown in the following formula:

[0081]

[0082] wherein, G c is a geometric center position of the planning area, f2(X) is a second objective function for the layout of the device set, and through the second objective function, the device barycenter can be made to be as close as possible to the geometric center position of the planning area.

[0083] In the process of determining the third objective function for the layout of the device set, the load-bearing capacity of the device set can be first determined according to the weight and the load-bearing distribution function of each device in the device set. Then, the load-bearing capacity difference of the device set can be determined according to the load-bearing capacity of the device set and the preset maximum load-bearing capacity. Finally, the third objective function for the layout of the device set can be determined according to the load-bearing capacity difference of the device set, as shown in the following formula:

[0084]

[0085] wherein, W i is the weight of the i-th device in the device set, I(x i ) is the load-bearing distribution function of the i-th device in the device set, C max is the maximum load-bearing capacity, and f3(X) is the third objective function for the layout of the device set, and through the third objective function, the device load-bearing distribution can be constrained.

[0086] Step S103, the layout positions of the device set are optimized and solved based on the multiple objective functions, and a layout result of the device set is obtained.

[0087] In the embodiments of the present application, the layout positions of the device set can be optimized and solved based on the first objective function, the second objective function and the third objective function through a preset multi-objective optimization algorithm, so as to obtain the layout result of the device set.

[0088] The multi-objective optimization algorithm can include but is not limited to a particle swarm optimization (PSO) algorithm and a genetic algorithm, and the specific multi-objective optimization algorithm used in the embodiments of the present application is not limited.

[0089] Step S104, the layout result of the device set is simulated and displayed in the preset electronic sand table.

[0090] Further, in response to the operation instruction of the user on the electronic sand table, the layout result of the device set simulated and displayed in the electronic sand table can also be adjusted.

[0091] Figure 2As shown in the schematic diagram of the simulation display interface of the electronic sand table, the toolbar in the simulation display interface has functions such as saving, resetting, common problem indexing, zooming out, zooming in, exiting, exporting drawings, layout model saving and reading, etc. The simulation display interface of the electronic sand table is set as empty, and the interface left side shows a device model menu bar, which can include but is not limited to low-pressure cylinder devices, generator devices, speed regulation devices, special tools and other models. Each type of model menu shows a single model in the form of a thumbnail, and the model name and geometric information can be viewed by clicking the model with a mouse.

[0092] As shown in Figure 3 , the operator can click the device and material model thumbnail in the menu bar with a mouse, and the corresponding single 2D model appears in the fixed position of the simulation display interface. The operator can use the mouse to drag the model for layout simulation. The overall scale of the 2D model of the plant and the device to be laid out is consistent with the simulation display interface of the electronic sand table. The east, west, south and north directions of the simulation display interface of the electronic sand table are increased with scale marks to estimate the distance between the layout device and the wall (unit: m), providing a reference for the overall layout of the device.

[0093] The electronic sand table simulation program can save the deduced layout model in the program, support the saved layout model to be called by the program for re-editing, realize the planning and adjustment of the deduction process, and allow the upper limit of the number of layout models saved in the program to be flexibly set according to actual conditions, for example, it can be set to 5 or less. In addition, the program supports exporting the deduced layout model to a picture format (PNG or JPG) and saving it locally. This picture format file cannot be re-edited.

[0094] As shown in Figure 4 , the 2D model in the electronic sand table simulation program can move along the X and Y axes. The operator can use the mouse to click the model to move it to a new layout position. Figure 5 As shown in Figure 6 , the 2D model in the electronic sand table simulation program can also rotate 90 degrees clockwise or counterclockwise each time. As shown in Figure 6 , the electronic sand table simulation program can create a new 2D model, customize shape, name, size information, and text labeling function, and the model can be filled with different colors to distinguish the types of devices and materials represented by the new model. As shown in Figure 7 , the electronic sand table simulation program can prompt the interface when the models interfere with each other during the simulation layout process, but the layout of the models on top of each other can still be realized. The low-pressure cylinder outer cylinder needs to be supported by a tie beam support, so in the simulation display interface of the electronic sand table simulation program, the placement position of the support pier when supporting the low-pressure outer cylinder can be supplemented according to the tie beam size and the contact surface distribution of the low-pressure outer cylinder as shown in Figure 8 .

[0095] Considering the construction period and the sequence of equipment installation, the equipment layout scheme can be optimized according to the period requirement and the equipment hoisting sequence. For example, some equipment needs to be installed in advance and space is left, and other equipment may need to wait until the equipment installation is completed to have enough space for layout. By optimizing the installation sequence of the equipment, the equipment hoisting and construction plan are optimized synchronously, avoiding time waste and equipment conflicts in construction.

[0096] During the construction process, as the equipment installation progresses, the construction resources (such as cranes, tools, personnel, etc.) will change. By tracking the use of resources in real time, resources can be dispatched in a timely manner to avoid construction delays caused by resource conflicts and provide optimization suggestions.

[0097] Nuclear power plant overhaul involves the cooperation of multiple professional departments (such as modification, machinery, service, etc.), and a multi-user real-time collaboration function can be provided to support parallel and cross operations of different departments in the same project, reduce communication lag and resource conflicts through sharing of real-time data and plan collaboration.

[0098] During the equipment layout process, possible space conflicts and interference between equipment can be detected in real time. For example, some equipment may not be able to be installed smoothly due to too compact layout during subsequent construction. Through intelligent algorithms, potential conflicts are identified and adjustment schemes are provided.

[0099] In a specific implementation manner of the embodiment of the application, further center of gravity estimation and equipment load bearing analysis can be performed. For each equipment, the center of gravity position of the equipment can be determined according to the geometric shape and mass distribution information of the equipment, as shown in the following formula:

[0100]

[0101] wherein m i is the mass of each component, x i , y i , z i is the center of gravity coordinate of each component, X c , Y c , Z c is the center of gravity position of the equipment. The calculated center of gravity position can be visualized on the equipment model to help users avoid center of gravity imbalance problems during equipment hoisting during the layout process.

[0102] Combined with the load bearing standard of each area of the plant, the application embodiment can calculate the load bearing pressure of each area after layout according to the weight and distribution of the equipment, as shown in the following formula:

[0103]

[0104] Wherein, P is the bearing pressure per unit area, W is the total weight of the equipment, and A is the floor area of the equipment. The embodiment of the present application can check whether each layout scheme meets the bearing standard of the factory floor in real time, and automatically give a safety warning or adjustment suggestion.

[0105] To sum up, the embodiment of the present application determines a device set to be laid out in the construction of the nuclear power plant overhaul project group, wherein the device set includes more than one device; determines a plurality of objective functions for laying out the device set based on the space utilization, the center of gravity offset and the bearing capacity constraint of the device set; optimizes and solves the layout position of the device set based on the plurality of objective functions to obtain the layout result of the device set; and simulates and displays the layout result of the device set in a preset electronic sand table. Through the embodiment of the present application, the layout position of the device can be optimized and solved based on the plurality of objective functions, and simulated and displayed in the electronic sand table. The whole processing process does not need manual intervention, breaks away from the dependence on personal experience of relevant professionals, effectively improves the efficiency, can avoid errors caused by personal negligence, has higher accuracy, and can better meet the actual requirements of the construction of the nuclear power plant overhaul project group.

[0106] It should be understood that the size of the serial number of each step in the above embodiment does not mean the order of execution, and the execution order of each process should be determined according to its function and inherent logic, and should not constitute any limitation on the implementation process of the embodiment of the present application.
