下面结合附图，对本发明实施例提供的一种基于数值算法的接地选型方法进行介绍。The following describes a method for selecting a grounding type based on a numerical algorithm provided by an embodiment of the present invention with reference to the accompanying drawings.
如图1所示，本发明实施例提供的一种基于数值算法的接地选型方法，可以包括如下步骤：As shown in FIG. 1 , a method for selecting a grounding type based on a numerical algorithm provided by an embodiment of the present invention may include the following steps:
S101，获取目标区域的土壤参数，其中，该土壤参数包括土壤电阻率。该目标区域可以为任一存在接地需求的土地区域，例如：安装有输电设备的土地区域。S101. Acquire soil parameters of a target area, where the soil parameters include soil resistivity. The target area can be any land area with grounding requirements, such as a land area where power transmission equipment is installed.
考虑到目标区域的土壤参数可以预先在执行主体的本地存储，也可以通过与用户交互的方式获取，这样，获取目标区域的土壤参数的实现方式可以存在多种。示例性的，在一种实现方式中，获取目标区域的土壤参数可以包括：从本地存储的目标关联关系中，查询该目标区域的土壤参数，其中，该目标关联关系为预先构建的关于土壤参数与区域之间的关联关秀。Considering that the soil parameters of the target area can be stored locally in the execution body in advance, or can be obtained through interaction with the user, thus, there can be various implementations for obtaining the soil parameters of the target area. Exemplarily, in an implementation manner, acquiring the soil parameters of the target area may include: querying the soil parameters of the target area from a locally stored target association relationship, where the target association relationship is a pre-built soil parameter. The association with the region Guanxiu.
示例性的，在另一种实现方式中，获取目标区域的土壤参数可以包括：在用户界面显示用于输入土壤参数的用户界面，以使用户通过用户界面输入该目标区域的土壤参数。其中，本发明实施例对显示的用户界面的具体形式不做限定。Exemplarily, in another implementation manner, acquiring the soil parameters of the target area may include: displaying a user interface for inputting soil parameters on the user interface, so that the user can input the soil parameters of the target area through the user interface. Wherein, the embodiment of the present invention does not limit the specific form of the displayed user interface.
为了进一步了解目标区域的土壤特性，示例性的，该目标区域的土壤参数还可以包括地形地貌，例如：平原或者高原等；土壤类型，例如：砖红壤、黄壤等；土壤腐蚀等级，例如：弱腐蚀性，中腐蚀性等，如下表所示：In order to further understand the soil characteristics of the target area, for example, the soil parameters of the target area may also include topography, such as: plain or plateau, etc.; soil type, such as: brick red soil, yellow soil, etc.; soil corrosion level, such as: weak Corrosive, medium corrosive, etc., as shown in the table below:
本发明仅将土壤的电阻率作为土壤参数进行研究，暂时不对其他参数进行考虑，有待于后续进行优化。The present invention only studies the resistivity of the soil as a soil parameter, and does not consider other parameters for the time being, and needs to be optimized in the future.
S102，基于该土壤参数，生成针对该输电设备的参数确定公式；该参数确定公式用于确定该输电设备对应的接地装置所包含的参数。S102 , based on the soil parameter, generate a parameter determination formula for the power transmission equipment; the parameter determination formula is used to determine the parameters included in the grounding device corresponding to the power transmission equipment.
考虑到接地装置可以包括多种，例如：接地模块、降阻布等等，那么，在进行接地选型时，该接地装置所包含的参数则可以存在多种，示例性的，在一种实现方式中，基于该土壤参数，生成针对该输电设备的参数确定公式，可以包括：根据该土壤参数，采用预设的融合公式，融合该接地装置所包含的参数，得到针对该输电设备的参数确定公式。其中，该融合公式可以存在多种，例如：该融合公式可以包括：将接地装置所包含的各参数，按照预设的比例系数相乘，或者，按照预设的权重系数，将接地装置所包含的各参数相加等等。Considering that the grounding device may include various types, such as: grounding module, resistance reduction cloth, etc., then, when selecting the grounding type, the parameters contained in the grounding device may exist in various types. Exemplarily, in an implementation In the method, generating a parameter determination formula for the power transmission equipment based on the soil parameters may include: according to the soil parameters, using a preset fusion formula to fuse parameters included in the grounding device to obtain a parameter determination formula for the power transmission equipment formula. Wherein, the fusion formula may exist in many kinds, for example: the fusion formula may include: multiply each parameter included in the grounding device according to a preset proportional coefficient, or, according to a preset weight coefficient, multiply the parameters included in the grounding device The parameters are added together, and so on.
示例性的，当接地装置所包含的参数包括：接地模块的电阻和降阻布的电阻时；该预设的融合公式可以包括：Exemplarily, when the parameters included in the grounding device include: the resistance of the grounding module and the resistance of the resistance reducing cloth; the preset fusion formula may include:
其中，Rn表征接地模块的电阻，Rd表征降阻布的电阻；Among them, Rn represents the resistance of the grounding module, and Rd represents the resistance of the resistance reducing cloth;

考虑到当接地装置包括多个接地模块和降阻布时，针对每一接地模块，该接地模块的降阻效果与该接地模块与输电设备的间距有关，也就是说，在为输电设备选取接地模块时，需要将每一接地模块与输电设备之间的间距作为考虑因素，例如，为每一接地模块设置一权重系数αi，进而可以提高接地装置选取的准确度。此外，考虑到土壤参数中的土壤电阻率会对接地模块和降阻布产生影响，那么，可以基于土壤电阻率，来生成针对该输电设备的参数确定公式。Considering that when the grounding device includes multiple grounding modules and resistance-reducing cloths, for each grounding module, the resistance-reducing effect of the grounding module is related to the distance between the grounding module and the power transmission equipment, that is, when selecting grounding for the power transmission equipment. When selecting modules, the distance between each grounding module and the power transmission equipment needs to be considered as a factor. For example, a weighting coefficient αi is set for each grounding module, so as to improve the accuracy of grounding device selection. In addition, considering that the soil resistivity in the soil parameters will have an impact on the grounding module and the resistance reducing cloth, a parameter determination formula for the power transmission equipment can be generated based on the soil resistivity.
此外，在实际应用中，接地模块存在不同的接地方式，例如：水平接地、垂直接地等，不同的埋设方式所对应的电阻值存在差异。这样，示例性的，当所述接地模块为水平接地时：In addition, in practical applications, the grounding module has different grounding methods, such as horizontal grounding, vertical grounding, etc., and the resistance values corresponding to different buried methods are different. In this way, exemplarily, when the grounding module is horizontally grounded:
其中，ρ表征土壤电阻率，l表征接地模块的长度，h表征接地模块的埋地深度，d表征接地模块的厚度，A为预设的形状系数，η为预设的调整系数；Wherein, ρ represents the soil resistivity, l represents the length of the grounding module, h represents the buried depth of the grounding module, d represents the thickness of the grounding module, A is a preset shape coefficient, and η is a preset adjustment coefficient;
当所述接地模块为垂直接地时：When the grounding module is vertically grounded:
其中，ρ表征土壤电阻率，l表征接地模块的长度，d表征接地模块的厚度，η为预设的调整系数。Among them, ρ represents the soil resistivity, l represents the length of the grounding module, d represents the thickness of the grounding module, and η is a preset adjustment coefficient.
S103，根据该参数确定公式，采用预设的数值算法，确定与该输电设备匹配的接地装置的参数，并根据该接地装置的参数为该输电设备选取对应的接地装置。S103, according to the parameter determination formula, use a preset numerical algorithm to determine the parameters of the grounding device matching the power transmission equipment, and select the corresponding grounding device for the power transmission equipment according to the parameters of the grounding device.
为了减少计算量，并提高计算的准确度，可以采用预设的数值算法，来确定与该输电设备匹配的接地装置的参数。示例性的，在一种实现方式中，根据该参数确定公式，采用预设的数值算法，确定与该输电设备匹配的接地装置的参数可以包括如下步骤A-C：In order to reduce the amount of calculation and improve the accuracy of the calculation, a preset numerical algorithm can be used to determine the parameters of the grounding device matching the power transmission equipment. Exemplarily, in an implementation manner, according to the parameter determination formula, using a preset numerical algorithm, determining the parameters of the grounding device matching the power transmission equipment may include the following steps A-C:
A，获取该输电设备的设备参数；A. Obtain the equipment parameters of the power transmission equipment;
其中，该输电设备的设备参数可以包括多种，示例性的，该设备参数可以包括：设备类型，例如：电站、杆塔等；电压等级，例如：110KV，220KV等。如下表所示：Wherein, the equipment parameters of the power transmission equipment may include a variety of, exemplarily, the equipment parameters may include: equipment type, such as: power station, tower, etc.; voltage level, such as: 110KV, 220KV, etc. As shown in the table below:
