In order to solve the above-mentioned problems, the embodiments of the present disclosure provide a method for reminding a fault of a power grid line, where the method is mainly applied in a risk reminding scenario that a natural disaster such as a snow storm may cause a fault of the power grid line, and the method is described below with reference to specific embodiments.

Fig. 1 is a flow chart of a method for reminding a fault of a power grid line according to an embodiment of the present disclosure, where the method may be executed by a fault reminding device of the power grid line, and the device may be implemented by software and/or hardware, and may be generally integrated in an electronic device. As shown in fig. 1, the method includes:

and 101, obtaining target fault parameter values of various faults corresponding to each power grid line.

The various faults of each power grid line may be calibrated according to the scene requirement, for example, in a snowstorm reminding scene, the various faults may include a plurality of types of tower heights, average heights of preset obstacles (for example, may be trees) in a preset range near the power grid line, channel widths of the power grid line (i.e., 2 times of distances from the power grid line to the nearest trees and other preset obstacles), average altitudes in a preset distance range where the power grid line is located, average temperature predicted values in a preset time period (for example, 24-hour time period from the current time) and accumulated rainfall predicted values in a preset second time period (for example, 24-hour time period from the current time).

In one embodiment of the present disclosure, in order to facilitate the subsequent impact on the fault risk of each power grid line, the target fault parameter value normalizes the processed parameter value, where in different application scenarios, the normalization processing is different, and the following is illustrated by way of example:

in some possible implementations, initial fault parameter values of various faults corresponding to each power grid line are obtained, maximum initial fault parameter values and minimum initial fault parameter values of various faults corresponding to a plurality of power grid lines are determined, and target fault parameter values of various faults corresponding to each power grid line are obtained according to the initial fault parameter values, the maximum initial fault parameter values and the minimum initial fault parameter values of various faults corresponding to each power grid line.

In this embodiment, the initial fault parameter value of each type of fault corresponding to each power grid line and the first difference value of the minimum initial fault parameter value may be calculated, and the ratio of the initial fault parameter value of each type of fault corresponding to each power grid line and the corresponding first difference value is taken as the corresponding target fault parameter.

In this embodiment, the initial fault parameter value and the first difference value of the minimum initial fault parameter value of each type of fault corresponding to each power grid line may also be calculated, the second difference value of the maximum initial fault parameter value and the minimum initial fault parameter value of each type of fault corresponding to each power grid line may be calculated, and the target fault parameter value of each type of fault corresponding to each power grid line may be determined according to the first difference value and the second difference value of each type of fault corresponding to each power grid line.

In this embodiment, the difference ratio of the first difference and the second difference may be directly used as the target fault parameter value.

In this embodiment, a difference ratio of the first difference and the second difference may be further calculated, where when each fault is a preset first fault, the difference ratio is determined to be a target fault parameter value of the preset first fault of each power grid line, and when each fault is a preset second fault, a third difference of the preset value and the difference ratio is calculated, and the third difference is determined to be a target fault parameter value of the preset second fault of each power grid line.

Wherein the first type of faults and the second type of faults are calibrated according to specific scenes, for example, for the ith power grid line, the corresponding types of faults are the tower heights (marked as G) of the power grid line _i (m) (i=1, 2, …, N), where N is the total number of the plurality of grid lines to be fault-handled), the average height of a preset obstacle (which may be a tree, for example) within a preset range around the ith grid line (denoted S) _i (m) (i=1, 2, …, N)), the channel width of the ith grid line (i.e., 2 times the distance of the grid line from the nearest tree or other preset obstacle) (denoted as T _i (m) (i=1, 2, …, N)), the average altitude of the ith grid line within a predetermined distance range (denoted as H) _i (m) (i=1, 2, …, N)), the ith grid line is located at an average temperature prediction value (denoted W) within a first preset time period from the current time (e.g. 24 hours from the current time) _i (m) (i=1, 2, …, N)), the ith grid line is located at a cumulative rainfall prediction (denoted as P) from the current second preset time period (e.g., 24 hours from the current time period) _i (m)(i＝1,2,…,N))。

Wherein the first type of fault comprises G _i (m)、H _i (m)、W _i (m) and P _i (m) the second type of faults includes S _i (m)、T _i (m)、H _i (m) according to the normalization method of , G _i (m) the corresponding target fault parameter value isS _i (m) the corresponding target fault parameter value isT _i (m) corresponding target fault parameter valuesH _i (m) the corresponding target fault parameter value isW _i (m) the corresponding target failure parameter value is +.>P _i (m) the corresponding target fault parameter value is

And 102, determining fault risk itemizing index values corresponding to various faults of each power grid line according to target fault parameter values corresponding to various faults.

In one embodiment of the disclosure, in order to determine the possible fault risk of each type of fault to the grid line, a fault risk score index value corresponding to each type of fault of each grid line is determined according to a target fault parameter value corresponding to each type of fault.

In some possible embodiments, a product value of a target fault parameter value corresponding to each type of fault and a corresponding preset weight may be calculated, and the corresponding product value is used as a fault risk score index value.

In some possible embodiments, the target fault parameter values corresponding to the various faults may be calculated according to a preset calculation formula, so as to obtain fault risk score index values corresponding to the various faults of each power grid line.

In some possible implementations, the preset calculation formula is shown in the following formula (1):

wherein A is a fault risk index value corresponding to various faults, and B is a fault risk index value corresponding to various faults.

Continuing with the example of embodiment of the ith grid line above, G _i (m) the corresponding failure risk score index value isS _i (m) the corresponding failure risk score index value is +.>T _i (m) corresponding failure risk score index value +.>H _i (m) the corresponding failure risk score index value is +.>W _i (m) the corresponding failure risk score index value is +.>P _i (m) the corresponding failure risk score index value is

And step 103, obtaining a target fault risk index value of each power grid line according to all fault risk index values corresponding to each power grid line.

After all fault risk index values corresponding to each power grid line are obtained, the influences of various faults are comprehensively considered, and target fault risk index values of each power grid line are obtained according to all fault risk index values corresponding to each power grid line.

In some possible implementation manners, various fault risk index values can be classified according to scenes, wherein the classification manners of the various fault risk index values can be calibrated according to scene needs, and the fault influence dimensions of the same type of fault risk index values on the power grid line can be similar.

In this embodiment, the various fault risk index values are classified into a first class fault risk index value, a second class fault risk index value and a third class fault risk index value, the first class fault risk index value, the second class fault risk index value and the third class fault risk index value in all the fault risk index values corresponding to each grid line are determined, and under the condition that the first class fault risk index value is single and the second class fault risk index value and the third class fault risk index value are multiple, a first summation value of all the second class fault risk index values corresponding to each grid line and a second summation value of all the third class fault risk index values corresponding to each grid line are calculated, and product calculation is performed on the first class fault risk index value, the first summation value and the second summation value corresponding to each grid line to obtain a corresponding product value as a target fault risk index value of each grid line.

In this embodiment, the above-mentioned ith power grid line is further used for example, where the first type of fault risk score index value is γ _i Alpha is an index value of a second type of fault risk sub-term _i And beta _i The third class of fault risk index value is theta _i 、η _i 、μ _i Wherein, the calculation method according to the above embodiment may obtain the target failure risk index value of the ith power grid line as E _i ＝γ _i (α _i +β _i )(θ _i +η _i +μ _i )。

And 104, determining a target power grid line meeting a preset reminding condition in the plurality of power grid lines according to the target fault risk index value, and carrying out fault reminding processing on the target power grid line.

In one embodiment of the present disclosure, a target power grid line meeting a preset reminding condition in a plurality of power grid lines is determined according to a target fault risk index value, and because the target fault risk index value is obtained according to various fault parameters, the accuracy is stronger, in addition, the preset reminding conditions are different in different application scenarios, in some possible implementation manners, the plurality of power grid lines can be ordered according to the order of the target fault risk index value from high to low, and the power grid lines of the preset number before are determined in the ordering result to be the target power grid lines meeting the preset reminding conditions;

in some possible implementation manners, a fault risk index threshold may be set according to scene requirements, and it is determined that a power grid line corresponding to a target fault risk index greater than the fault risk index threshold is a target power grid line sufficient to preset reminding conditions. Further, after the target power grid line is determined, fault reminding processing is performed on the target power grid line, for example, risk reminding can be sent to a preset platform, so that deployment of disaster resistant equipment and the like can be performed in time before natural disasters such as the corresponding snow storm and the like come, and occurrence of fault risks and the like can be avoided.

In summary, according to the fault reminding method for the power grid lines provided by the embodiment of the disclosure, target fault parameter values of various faults corresponding to each power grid line are obtained, fault risk itemized index values corresponding to various faults of each power grid line are determined according to the target fault parameter values corresponding to various faults, target fault risk index values of each power grid line are obtained according to all fault risk itemized index values corresponding to each power grid line, and then fault reminding processing is carried out on each power grid line according to the target fault risk index values.
