Detailed Description
The following describes the detailed implementation of the embodiments of the present invention with reference to the drawings. It should be understood that the detailed description and specific examples, while indicating and illustrating the invention, are not intended to limit the invention.
Fig. 1 is a flowchart of a method for constructing a digital twin model library of electric power according to an embodiment of the present invention. In this fig. 1, the construction method may include the steps of:
in step S10, a three-dimensional model of the electrical device and electrical parameters are acquired;
in step S11, determining a positional association relationship of the electrical device according to the three-dimensional model;
in step S12, determining an electrical correspondence of the electrical device according to the electrical parameter;
in step S13, matching the position association relationship and the electrical correspondence relationship with the electrical equipment to obtain a twin model assembly of the electrical equipment;
in step S14, each twin model component is integrated to obtain a digital power twin model library.
In this construction method as shown in fig. 1, step S10 may be used to acquire a three-dimensional model of the electrical device and electrical parameters. Considering that the initial three-dimensional models of different electrical devices are single in size, the size difference often exists when the combination is called in actual needs. Thus, in one example of the invention, the three-dimensional model may be scaled as it is acquired to obtain different volumetric versions of the same three-dimensional model.
Step S11 may be used to determine a positional association of the electrical device according to the three-dimensional model. The positional association may be used to determine whether the three-dimensional model has an edge collision when the three-dimensional model is closely spaced. The specific method for acquiring the positional association relationship may be in various forms known to those skilled in the art. In one example of the present invention, the positional association relationship may be obtained by a method as shown in fig. 2. In fig. 2, the obtaining of the positional association relationship may include the steps of:
in step S20, the position matching relationship of each two electrical apparatuses in the history electrical apparatus position matching relationship is calculated according to the preset history electrical apparatus position matching set. Wherein the set of historical electrical device location matches may be obtained by a method as shown in fig. 3. In the method of fig. 3, the method of obtaining the historical electrical device location matching set may include the steps of:
in step S30, a historical power digital twin model is acquired;
in step S31, the position information of the electrical device of the historical power digital twin model is deconstructed;
in step S32, it is determined whether the edge distance of each two electrical devices is less than or equal to a preset distance threshold;
in step S33, in the case where it is determined that the edge distance is less than or equal to the distance threshold, it is determined that the two electrical devices have a position matching relationship;
in step S34, the position matching frequency of the two electrical devices is acquired;
in step S35, it is determined whether the position matching frequency is greater than or equal to a preset frequency threshold;
in step S36, if the position matching frequency is greater than or equal to the frequency threshold, adding two electrical devices to the historical electrical device position matching set;
in step S37, if it is determined that the position matching frequency is smaller than the frequency threshold, it is determined whether or not there is another position matching relationship in any one of the two electrical devices;
if it is determined that there is no other positional matching relationship, the two electric devices are added to the history electric device positional matching set, that is, the step S36 is executed.
In the method as shown in fig. 3, step S30 is used to acquire a historical power digital twin model. The historical power digital twin model may be obtained directly from a model database of the power system. Steps S31 to S32 are for determining whether the positional relationship of each two electrical apparatuses meets a condition, that is, the edge distance is less than or equal to a preset distance threshold. In the case of the satisfaction, it is determined that there is a positional matching relationship between the two electrical apparatuses at this time. However, considering that the early historical power digital twin model is constructed manually, fine position matching may not be considered in construction, and thus a certain error may exist. Therefore, in the case where it is determined that there is a positional relationship between the two devices, it is necessary to further determine the frequency of positional matching of the two electrical devices, that is, the number of times that the same two electrical devices have a positional relationship at this time, through step S34. And then judging whether the position matching frequency is greater than or equal to a preset frequency threshold or not through the step S35. In the case where it is determined in step S35 that the frequency of the position matching is greater than or equal to the frequency threshold, it is indicated that the positional relationship is correct at this time, and therefore, it is possible to directly add two devices to the historical electric device position matching set through step S36. Otherwise, the method is not added. If it is determined in step S35 that the frequency of the position matching is smaller than the frequency threshold, it is indicated that the number of times of matching of the electrical device is too small. There are two general possibilities for this situation, one is that the foregoing reasons, i.e. the manual construction does not fully consider the matching accuracy, and is corrected in the subsequent use process, so that the frequency of position matching is too low; the other is that the frequency of use of the electric equipment is too small, and only one or a plurality of position matching relations exist. In this case, it is obviously difficult to determine whether or not it is necessary to join the historical electric device position set by the position matching frequency, but in order to avoid information loss, the historical electric device position set is incomplete, so that step S36 may be directly performed.
In step S21, the version selected by the two electrical apparatuses at the time of matching is determined according to the positional matching relationship.
Step S12 may be used to determine an electrical correspondence of the electrical device based on the electrical parameter. The electrical correspondence may be used to determine whether the electrical devices can be placed into the same device topology. The specific method for obtaining the electrical correspondence may be in various forms known to those skilled in the art. In one example of the invention, the electrical correspondence may be obtained by a method as shown in fig. 4. In fig. 2, the obtaining the electrical correspondence may include the steps of:
in step S40, a voltage class or a power class of each electrical device is determined;
in step S41, dividing the electrical equipment into a plurality of class sets according to the magnitude relation of the voltage class or the power class and the preset interval;
in step S42, an electrical correspondence is determined from the level set.
Step S13 may be used to match the position association relationship and the electrical correspondence relationship with the electrical devices, so as to obtain a twin model component of the electrical devices, thereby completing the improvement of the attribute information of each electrical device. Finally, each twin model component can be integrated through step S14 to obtain a digital twin model library of power.
In another aspect, the invention also provides a construction system of an electric power digital twin model library, the construction system comprising a processor configured to perform the construction method as described in any one of the above. Specifically, the construction method may include the steps of:
in step S10, a three-dimensional model of the electrical device and electrical parameters are acquired;
in step S11, determining a positional association relationship of the electrical device according to the three-dimensional model;
in step S12, determining an electrical correspondence of the electrical device according to the electrical parameter;
in step S13, matching the position association relationship and the electrical correspondence relationship with the electrical equipment to obtain a twin model assembly of the electrical equipment;
in step S14, each twin model component is integrated to obtain a digital power twin model library.
In this construction method as shown in fig. 1, step S10 may be used to acquire a three-dimensional model of the electrical device and electrical parameters.

Wherein the set of historical electrical device location matches may be obtained by a method as shown in fig. 3. In the method of fig. 3, the method of obtaining the historical electrical device location matching set may include the steps of:
in step S30, a historical power digital twin model is acquired;
in step S31, the position information of the electrical device of the historical power digital twin model is deconstructed;
in step S32, it is determined whether the edge distance of each two electrical devices is less than or equal to a preset distance threshold;
in step S33, in the case where it is determined that the edge distance is less than or equal to the distance threshold, it is determined that the two electrical devices have a position matching relationship;
in step S34, the position matching frequency of the two electrical devices is acquired;
in step S35, it is determined whether the position matching frequency is greater than or equal to a preset frequency threshold;
in step S36, if the position matching frequency is greater than or equal to the frequency threshold, adding two electrical devices to the historical electrical device position matching set;
in step S37, if it is determined that the position matching frequency is smaller than the frequency threshold, it is determined whether or not there is another position matching relationship in any one of the two electrical devices;
if it is determined that there is no other positional matching relationship, the two electric devices are added to the history electric device positional matching set, that is, the step S36 is executed.
In the method as shown in fig. 3, step S30 is used to acquire a historical power digital twin model. The historical power digital twin model may be obtained directly from a model database of the power system. Steps S31 to S32 are for determining whether the positional relationship of each two electrical apparatuses meets a condition, that is, the edge distance is less than or equal to a preset distance threshold.

Otherwise, the method is not added. If it is determined in step S35 that the frequency of the position matching is smaller than the frequency threshold, it is indicated that the number of times of matching of the electrical device is too small.

In this case, it is obviously difficult to determine whether or not it is necessary to join the historical electric device position set by the position matching frequency, but in order to avoid information loss, the historical electric device position set is incomplete, so that step S36 may be directly performed.
In step S21, the version selected by the two electrical apparatuses at the time of matching is determined according to the positional matching relationship.
Step S12 may be used to determine an electrical correspondence of the electrical device based on the electrical parameter. The electrical correspondence may be used to determine whether the electrical devices can be placed into the same device topology. The specific method for obtaining the electrical correspondence may be in various forms known to those skilled in the art. In one example of the invention, the electrical correspondence may be obtained by a method as shown in fig. 4. In fig. 2, the obtaining the electrical correspondence may include the steps of:
in step S40, a voltage class or a power class of each electrical device is determined;
in step S41, dividing the electrical equipment into a plurality of class sets according to the magnitude relation of the voltage class or the power class and the preset interval;
in step S42, an electrical correspondence is determined from the level set.
Step S13 may be used to match the position association relationship and the electrical correspondence relationship with the electrical devices, so as to obtain a twin model component of the electrical devices, thereby completing the improvement of the attribute information of each electrical device. Finally, each twin model component can be integrated through step S14 to obtain a digital twin model library of power.
In yet another aspect, the present invention also provides a computer-readable storage medium storing instructions for being read by a machine to cause the machine to perform a construction method as set forth in any one of the above.
Through the technical scheme, the embodiment of the invention provides a construction method and a construction system of an electric power digital twin model library, wherein the construction method and the construction system increase relation constraint on electric equipment by constructing position incidence relation and electric corresponding relation aiming at the electric equipment, and add the relation constraint into the attribute of the electric equipment, so that the electric power digital twin model library is formed, and the system can determine the range of the electric equipment to be screened through the position incidence relation and the electric corresponding relation when constructing the twin model, so that the construction speed and efficiency of the twin model are improved.
