Detailed Description
The following detailed description of embodiments of the invention refers to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating embodiments of the invention, are given by way of illustration and explanation only, not limitation.
In the embodiments of the present invention, unless otherwise specified, the use of directional terms such as "upper, lower, top, and bottom" is generally used with respect to the orientation shown in the drawings or the positional relationship of the components with respect to each other in the vertical, or gravitational direction.
In addition, if there is a description of "first", "second", etc. in the embodiments of the present invention, the description of "first", "second", etc. is for descriptive purposes only and is not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature. In addition, technical solutions between the various embodiments can be combined with each other, but must be realized by a person skilled in the art, and when the technical solutions are contradictory or cannot be realized, the combination of the technical solutions should be considered to be absent and not be within the protection scope of the present invention.
Fig. 1 is a flow chart illustrating a modeling method for a substation according to an embodiment of the present invention. In fig. 1, the modeling method may include:
in step S10, a three-dimensional model of the formed substation and basic information of the substation to be generated are acquired.
In step S11, component information included in the substation to be generated is determined based on the basic information.
In step S12, a common subset of the formed three-dimensional model and component information is determined.
In step S13, a difference set of the component information and the common subset is determined.
In step S14, the formed three-dimensional model is modified according to the difference set to generate a three-dimensional model to be generated.
In this embodiment, the component information may include coordinates, model, and attitude of each device of the substation. The formed three-dimensional model of the substation may be a three-dimensional model prestored in the system, or may be a three-dimensional model generated in the memory of the current system.
Take the formed three-dimensional model as a pre-stored three-dimensional model in the system as an example. In the prior art, each time a three-dimensional model is generated, identification needs to be performed on basic information of a transformer substation, each component is searched in a preset database, and then combined rendering is performed on the basis of the searched components, so that the three-dimensional model is obtained. Thus, although a three-dimensional model of the substation can be obtained, a large load is imposed on the system because each generation process requires a recombination of the components. In fact, because the structures of the substations are basically the same, and in an experimental environment, the differences between the actually adopted models of different substations are relatively small, if the models are generated each time and combined again, unnecessary waste of system computing resources is caused. Therefore, a plurality of three-dimensional models can be pre-stored in the system and modified based on the pre-stored three-dimensional models, so that the load of the system is reduced while the three-dimensional models are generated.
However, if there is no suitable selection method in the process of selecting the three-dimensional model, the load of the system is not reduced by the method, and the calculation amount of the system is increased. Therefore, in order to reduce the complexity of the algorithm, the inventor designs corresponding similarity for the matching result of each three-dimensional model according to the characteristics of the component. Taking the example that the component information includes the coordinates, models and postures of each device of the substation, the model and posture of the device on each ground coordinate can be matched one by one on the basis of the ground coordinates of the substation. In particular, the method may comprise the steps as illustrated in fig. 2. In fig. 2, the method may include:
in step S20, establishing a three-dimensional coordinate system with the bottom of the substation as an xOy plane and the vertical direction as the z direction;
in step S21, equally dividing the bottom of the substation into a plurality of cells in the xOy plane;
in step S22, comparing the two three-dimensional models with respect to the components contained in each cell;
in step S23, the similarity of the two three-dimensional models is calculated with respect to the result of the alignment. Specifically, the similarity may be calculated according to formula (1),
where F (t) is the similarity of the tth formed three-dimensional model (one of the two three-dimensional models), N is the number of locations in the basic information, xi tAn indicator variable, x, of whether the component at the ith position in the basic information (the other of the two three-dimensional models) is the same as the component at the ith position in the t-th formed three-dimensional modeli t1 means the same as each other, xi t0 means that they are different from each other, yi tIth bit in basic informationAn indicator variable, y, of whether the pose of the component at the location is the same as the pose of the component at the ith location of the tth formed three-dimensional modeli t1 means the same as each other, yi t0 means that the two are different.
In step S24, the three-dimensional model with the largest similarity is selected and modified.
Taking the formed three-dimensional model as an example of a formed three-dimensional model, in the prior art, the formed three-dimensional model of the substation needs to be updated in real time, and for example, the indication number of the meter device, the weather condition, and the like need to be updated. At this time, if any of the readings of the meter devices, the weather conditions, and the like needs to be updated, the load of the system is greatly increased if the three-dimensional model of the entire substation is reconstructed. Therefore, the inventor designs the method of the invention aiming at the technical problem, so that only the difference set of the two models needs to be updated in the actual updating process, thereby greatly reducing the load of the system.
In another aspect, the present invention also provides a modeling system for a substation, which may include a processor that may be configured to the modeling method as described in any one of the above.
In yet another aspect, the present invention also provides a storage medium which may store instructions which are readable by a machine to cause the machine to perform any of the modeling methods described above.
According to the technical scheme, the modeling method, the modeling system and the storage medium for the transformer substation provided by the invention form a new three-dimensional model by modifying the existing three-dimensional model of the transformer substation, so that the load of equipment is reduced and the operation resources of the equipment are saved while the model reconstruction is completed.

It should be noted that the various features described in the above embodiments may be combined in any suitable manner without departing from the scope of the invention.
