Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of and not restrictive on the broad application.
In a specific application scenario of the transformer substation flood control optimization design method, the transformer substation flood control optimization design device, the computer equipment and the storage medium, the method comprises the following steps:
the traditional technology provides a method for directly filling a high site for flood control of the whole transformer substation, but the method has the defects that a large amount of sandy soil is required to be purchased for filling in low-lying areas to form large filling side slopes, so that the manufacturing cost is high, the construction period is long, in addition, the filling on a foundation is high, the additional load on the foundation is large, the consolidation settlement of the filling per se can cause the settlement of the site of the station area, and the like.
The traditional technology also provides a method for directly adopting a flood control wall to control flood, but the method has the defects that the flood control wall required to be arranged in a low-lying area is too high and exceeds the applicable economic height of the flood control wall, and the deformation joint of the flood control wall and the flood control gap at the gate opening are difficult to process.
The traditional technology provides a method for preventing flood by lifting a building and an equipment base, but the method is only suitable for the condition of low flood prevention water level, is not suitable after the site and the flood prevention water level exceed a certain height, and is inconvenient to operate and maintain in a site area and a power distribution area due to the fact that a foundation is lifted.
According to the flood control optimization design method, the flood control optimization design device, the computer equipment and the storage medium of the transformer substation can adopt different flood control strategies for the substation area and the power distribution area respectively according to different flood control characteristics of the substation area and the power distribution area, and the filling heights are selected for the substation area and the power distribution area respectively so as to meet the requirements of the substation area and the power distribution area on flood control design.
In order to solve the technical problem that the conventional flood control design scheme cannot meet the requirements of functions of a pre-site area and a distribution area on flood control design, and thus a transformer substation has a flood control risk, in an embodiment, as shown in fig. 1, a transformer substation flood control optimal design method is provided, and includes the following steps:
step S110, acquiring the filling height of the pre-site area according to the flood control standard water level, and selecting a plurality of filling heights of the power distribution area based on the filling height of the pre-site area; the filling height of the pre-station area is greater than that of the distribution area.
The transformer substation is a place for converting voltage and current, receiving electric energy and distributing electric energy in an electric power system, belongs to an important hub in an electric power facility system, and has great influence on social production and life. The general transformer substation layout is divided into a substation front area and a power distribution area, wherein the substation front area is an entrance and an exit of the transformer substation, a main control building, an area patrol life center and other auxiliary production building layout areas. The distribution area is a main production facility in a transformer substation, and the arrangement area of each voltage class of power equipment, such as various transformers, switch equipment and protection equipment. In one example, the pre-site area and the distribution area are obtained by dividing a flood control area of the transformer substation according to preset rules. Further, the preset rule is that the pre-set area accounts for one fifth of the flood control area of the transformer substation. Of course, according to the actual substation construction requirements, the preset rule can also be changed, for example, the pre-site area occupies one sixth of the flood control area of the substation, or the pre-site area occupies one fourth of the flood control area of the substation.
The flood protection standard water level is a flood protection standard which is determined according to the importance of a flood protection object, the severity of flood disasters and the influence of the flood disasters and is met by the flood protection object or the engineering, and the specific size of the flood protection standard water level is changed according to different places. In one example. The designed flood level of a certain local recurrence period calculated by a frequency method can be used as a flood control standard. In another example, the flood level or the maximum waterlogging level due to rainfall may be obtained according to the local recording of the rainfall of the year, and the flood level or the maximum waterlogging level may be used as the flood control standard level. So that the substation can be protected against the strongest flooding.
The filling height of the pre-station area is the height of filling with sand in the pre-station area. In one example, the pre-site area is filled with a high flood level or a maximum waterlogging level of 0.5 meters. The district is mainly used for flood control by filling high sites.
The power distribution area is filled with sand and soil at a high height. And taking the filling height of the pre-site area as a reference, selecting different filling heights of the power distribution area (the filling height of the power distribution area is smaller than the filling height of the pre-site area), designing different flood control schemes, and selecting the optimal flood control scheme from the different flood control schemes. In one example, a plurality of distribution area fill heights are selected in steps of 0.5 meter height difference based on the pre-site fill height. In other words, the following formula can be used:
power distribution area fill height = pre-site area fill height-n 0.5 n represents a positive integer
Therefore, the selection of the filling height of the distribution area is simplified, and the flood control of the transformer substation is convenient to establish. Because the filling height of the distribution area is less than that of the pre-station area, the distribution area can not completely prevent flood, and the distribution area adopts a method of combining a filling field with a flood wall (flood bank) to prevent flood.
And step S120, operating the flood control optimization design model of the transformer substation by taking the height difference between the pre-substation area filling height and the distribution area filling height as an iteration variable.
The transformer substation flood control optimization design model is used for overall planning and totaling of resources which are optimized and designed for transformer substation flood control construction. In the transformer substation, the pre-site area filling height can be determined according to the standard flood control water level, the site area (also called floor area) of the transformer substation is fixed, therefore, the site areas of the pre-site area and the power distribution area are also fixed, and in the overall planning and totaling process of the construction resources, the height difference between the pre-site area filling height and the power distribution area filling height is the only variable, so that the height difference between the plurality of power distribution area filling heights selected in the step S110 and the pre-site area filling height can be used as the iteration variable of the transformer substation flood control optimal design model to operate the transformer substation flood control optimal design model. In one example, the substation flood protection optimal design model is a substation flood protection cost model for totalizing costs of resources optimally designed for substation flood protection construction.
In a specific embodiment, as shown in fig. 2, a transformer substation flood protection optimization design model is obtained based on the following steps:

The substation size database stores all the sizes of the substation, the distribution area and the pre-site area, for example, when the area of the substation is a rectangular area, the sizes include the length, width, perimeter and site area of the substation, the length, width, perimeter and site area of the distribution area, and the length, width, perimeter and site area of the pre-site area. The transformer substation size database is pre-established, and when the transformer substation size database needs to be used, related data can be directly obtained from the transformer substation size database.
Step S220, obtaining the size of the flood wall of the power distribution area according to the height difference and the perimeter of the power distribution area;
the earth filling height of the power distribution area is smaller than that of the earth filling height of the front area of the station, so that the earth filling height of the power distribution area is also smaller than the standard flood control water level. Specifically, the height difference can be used as the height of the flood control wall, the length of the flood control wall can be obtained according to the power distribution perimeter, and further, the thickness of the flood control wall can be selected according to the height of the flood control wall and by combining engineering mechanics.
And step S230, determining the size of the retaining wall of the transformer substation according to the perimeter and the height difference of the transformer substation and the filling height of the pre-station area.
Among them, the retaining wall is used to prevent the loss of sand filled in the pre-station area and the power distribution area and to improve the flood control strength. Specifically, the perimeter of the transformer substation is used as the length of the retaining wall, the filling height of the pre-stop area is used as the height of the retaining wall of the pre-stop area, the difference value between the filling height and the height difference of the pre-stop area is used as the height of the retaining wall of the power distribution area, and further the thickness of the retaining wall is selected according to the height of the retaining wall and by combining engineering mechanics.
And S240, taking the height difference as an iterative variable, and obtaining the flood control optimized design model of the transformer substation based on the site area of the pre-site area, the site area of the power distribution area, the soil filling height of the pre-site area, the soil filling height of the power distribution area, the size of the flood control wall and the size of the retaining wall.
In a specific example, as shown in fig. 3, the step of obtaining the substation flood control optimization design model based on the pre-site area, the distribution area, the pre-site fill height, the distribution area fill height, the flood control wall size, and the retaining wall size by using the height difference as an iterative variable includes:
step S310, obtaining a site front soil filling amount model according to the site front soil area and the site front soil filling height.
Wherein, in one example, the product of the site area of the pre-site and the filling height of the pre-site is used as the filling amount model of the pre-site.
And step S320, obtaining a power distribution area soil filling amount model according to the power distribution area ground area and the power distribution area soil filling height.
In one example, the product of the power distribution area ground area and the power distribution area fill height is used as a power distribution area fill quantity model.
And step S330, obtaining a total filling quantity model of the transformer substation according to the pre-station filling quantity model and the distribution area filling quantity model.
And taking the sum of the pre-station soil filling amount model and the distribution area soil filling amount model as a total soil filling amount model of the transformer substation.
And step S340, obtaining a flood wall volume model according to the size of the flood wall.
Wherein, the volume model of the flood control wall is calculated according to the dimensions (length, width and height) of the flood control wall.
And step S350, obtaining a retaining wall volume model according to the size of the retaining wall.
Wherein, the volume model of the retaining wall is calculated according to the size (length, width and height) of the retaining wall.
And S360, obtaining the flood control optimal design model of the transformer substation according to the total filling quantity model of the transformer substation, the flood control wall volume model and the retaining wall volume model.
Further, a transformer substation flood control optimization design model is obtained based on the following formula:
C＝P earthwork V Earthwork +P Flood control wall V Flood control wall +P Retaining wall V Retaining wall
Wherein C represents a transformer substation flood control optimization design model; p Earthwork Representing a fill weight; v Earthwork Representing a total filling quantity model of the transformer substation; p Flood control wall Representing the weight of the flood wall; v Flood control wall Representing a flood wall volume model; p Retaining wall Representing a retaining wall weight; v Retaining wall Representing a retaining wall volumetric model.
The above formula can also be expressed in the form:

Furthermore, the enclosing wall constructed by the transformer substation can be included in the transformer substation flood control optimal design model of the transformer substation, and therefore, the transformer substation flood control optimal design model is obtained based on the following formula:
C＝P earthwork V Earthwork +P Flood control wall V Flood control wall +P Retaining wall V Retaining wall +P Enclosure wall V Enclosure wall
Wherein, P Enclosure wall Representing the fence weight; v Enclosing wall A bounding volume model is represented.
The above formula can also be expressed in the form:
C＝P earthwork (k Earthwork ΔH+b Earthwork )+P Flood control wall (k Flood control wall ΔH 2 +k Flood control wall ΔH+b Flood control wall )+P Retaining wall (k Retaining wall ΔH 2 +k Retaining wall ΔH+b Retaining wall )+P Enclosure wall (k Enclosure wall ΔH+b Enclosure wall )
The perimeter of the transformer substation is used as the length of the enclosure, the height and the thickness of the enclosure are designed according to actual needs, and the enclosure volume model is obtained according to the length, the width and the thickness of the enclosure.
In one example, when the substation flood control optimal design model is the substation flood control cost model, the substation flood control cost model is obtained based on the following steps:
obtaining a pre-station area soil filling amount model according to the pre-station area ground area and the pre-station area soil filling height;

and taking the sum of the transformer substation filling cost model, the transformer substation flood control wall cost model and the transformer substation retaining wall cost model as the transformer substation flood control cost model.
Further, a transformer substation flood control cost model is obtained based on the following formula:

Wherein C' represents a transformer substation flood control construction cost model; p' Earthwork Representing the unit price of the filling; v Earthwork Representing a total filling quantity model of the transformer substation; p' Flood control wall Representing the unit price of the flood wall; v Flood control wall Representing a flood wall volume model; p' Retaining wall Representing the unit price of the retaining wall; v Retaining wall Representing a retaining wall volumetric model.
Furthermore, the enclosure of the transformer substation construction can be included in the transformer substation flood control cost model of the transformer substation, and therefore, the transformer substation flood control optimal design model is obtained based on the following formula:
C′＝P′ earthwork V Earthwork +P′ Flood control wall V Flood control wall +P′ Retaining wall V Retaining wall +P′ Enclosure wall V Enclosing wall
Wherein, P' Enclosing wall Represents a fence unit price; v Enclosure wall Representing a bounding volume model.
