Description

Technical Field

[0001] The present invention belongs to the technical field of data processing of power grid models and graphics, and in particular relates to a CIM-based rack resource modeling method and system. Background Art

[0002] During the operation of the power industry information system, when the power system manages medium and low voltage feeders and generates graphics, it is necessary to express the relationship between pole-mounted transformers, towers, JP cabinets and other equipment and their respective racks. Although CIM itself has standardized the model of power system resources, it is unable to express the concept of racks based on the existing CIM model.

[0003] For example, in the Proceedings of the Chinese Society for Electrical Engineering published in 2012, the relevant content entitled "Feeder Modeling and Application Based on CIM" was disclosed, which specifically disclosed: There has been controversy over the recognition and modeling of feeders in the common information model (CIM) for distribution networks. Starting from this basic issue of distribution network operation and management application under the background of smart grids, this paper discusses the evolution of feeders in CIM modeling, and uses the current official version of the CIM model to propose different modeling methods for feeders in static and dynamic situations. On the basis of not expanding the CIM model, based on the information integration needs of power grid management, the feeder messages that follow the IEC 61968 standard are expanded, the data exchange mode in the feeder management business scenario is clarified, and the static properties of feeders in equipment management and the unified expression and application of dynamic characteristics after changes in operation mode are solved.

[0004] The above-mentioned document extends the distribution line related classes of CIM, but does not involve how the rack is extended based on CIM.

[0005] In the "Research on Distribution Line Information Model Based on CIM" published in 2023, it is specifically disclosed that: the common information model (CIM) and the extended models of the common information model, CIM / E (E based Common Information Model) and CIM / G (G based Common Information Model), are analyzed in detail, providing theoretical and technical support for distribution line data information modeling and distribution line element information modeling. Based on the CIM model and the CIM / E model, the data attributes of distribution line electrical equipment and the subordinate relationships between distribution line electrical equipment are described in detail, the establishment of the distribution line electrical equipment data information model is completed, and the display of distribution line electrical equipment attributes is realized. Based on the CIM model and the CIM / G model, the graphics and format of the distribution line element are described in detail, the establishment of the distribution line element information model is completed, and the display of the distribution line element is realized. Based on the CIM model, the distribution line topology class and topology class association modeling are completed, and the distribution line topology analysis method is described in detail, realizing the topological connection display of the distribution line. Based on the binding association method and the plug-in association method, the distribution line data information model and the distribution line graphic element information model are associated to realize the binding of data information and graphic element information. Finally, this paper completes the establishment of the distribution line information model based on the CIM model, CIM / E model and CIM / G model.

[0006] However, the above literature does not involve how to expand the test bench based on CIM, and there is still room for improvement in the accuracy of power grid model expression and the efficiency of graphics generation. Summary of the invention

[0033] It should be noted that the following detailed descriptions are exemplary and are intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.

[0034] It should be noted that the terms used herein are for describing specific embodiments only and are not intended to be limiting of exemplary embodiments according to the present invention.

[0035] In the absence of conflict, the embodiments of the present invention and the features of the embodiments may be combined with each other.

[0036] Embodiment 1

[0037] The prior art described in the aforementioned background technology does not involve how to expand the test bench based on CIM. There is still room for improvement in the accuracy of power grid model expression and the efficiency of graphics generation. This embodiment discloses a modeling method for test bench resources based on CIM.

[0038] In general, the CIM-based rack resource modeling method provided in this embodiment may include the following steps:

[0039] Define the bench class and generate the bench object;

[0040] Adding properties of the test bench class, wherein the properties of the test bench class include a test bench pole tower, an internal station building, and a test bench pole tower sequence;

[0041] Determine the number of pole towers in the test bench object and generate the pole tower object, and fill in the properties of the test bench pole tower and the properties of the sequence of the test bench pole tower;

[0042] Determine the number of internal station rooms in the rack object and generate internal station room objects, and fill in the internal station room attributes;

[0043] All topological relationships of the rack objects are generated according to the CIM connection relationship to complete the modeling of the rack resources.

[0044] The properties of the rack class can be understood as the composite association relationship between the rack class and other classes in the rack. In this embodiment, the composite association relationship between the rack class and the rack tower, the internal station building, and the rack tower sequence is considered. Specifically:

[0045] Filling the properties of the test bench tower can be understood as establishing a composite association relationship between the test bench class and the test bench tower (Extends::LogicEquipmentcontainer);

[0046] Filling the sequence attributes of the test stand and pole tower can be understood as establishing a composite association relationship between the test stand class and the pole tower class with sequence number (Extends::SortedPole);

[0047] Filling the internal station building attributes can be understood as establishing a composite association relationship between the rack class and the internal station building container (Core::Substation) inherited from CIM.

[0048] The embodiment of the present invention realizes a new method of bench resource modeling based on CIM, improves the accuracy of power grid model expression and the efficiency of automatic graphics generation and processing, solves the insufficient support of bench resource modeling for existing power grid business, realizes a bench resource modeling method based on CIM, and improves the support level for power grid business.

[0049] As a further technical solution, the rack tower attribute in the attributes of the rack class represents the ordered sequence of towers contained in the rack, the internal station building attribute represents the internal station building of the rack, and the rack tower sequence is used to identify the order of the towers.

[0050] As a further technical solution, the type of the platform tower attribute is the Extends::SortedPole type sequence extended by CIM; the type of the internal station building attribute is the Core::Substation type sequence of CIM.

[0051] As a further technical solution, determining the number of pole towers in the rack object and generating the pole tower object specifically includes:

[0052] Define the tower type with serial number and sort the towers in the rack object;

[0053] Add the attributes of the pole tower type with serial numbers, wherein the attributes of the pole tower type with serial numbers include the serial number of the pole tower and the pole tower entity ID.

[0054] As a further technical solution, the type of the pole tower with serial number is Extends::SortedPole; the type of the pole tower serial number attribute is the Integer type of CIM, and the type of the pole tower entity id attribute is the Bigint type extended by CIM.

[0055] As a further technical solution, the platform class is Extends::TransformerPlateform.

[0056] As a further technical solution: the station class inherits the Core::Substation class in CIM.

[0057] Next, we will combine the Figure 1 , the technical solution of this embodiment is explained in detail. The method mentioned in this embodiment specifically includes:

[0058] 1. Define a pole type with serial numbers (Extends::SortedPole) to sort the poles in the rack.

[0059] 2. The properties of the tower type with serial number are as follows:

[0060] Property name type meaning Index CIM Integer Type Tower number Pole CIM extended Bigint type Indicates the tower entity id

[0061] like Figure 1As shown in the figure, the rightmost bottom box (Extends::SortedPole) is the UML class diagram of the pole class with serial number. Among them, Extends::SortedPole is the class name, Index represents the serial number of the pole, and Pole represents the ID of the pole type (Extends::LogicEquipmentcontainer) instance.

[0062] 3. Define the platen class (Extends::TransformerPlateform).

[0063] like Figure 1 As shown, the middle box (Extends::TransformerPlateform) is the definition of the platform class, which represents the platform.

[0064] 4. The station class inherits the Core::Substation class in CIM.

[0065] like Figure 1 As shown, when the aforementioned rack class is defined, it must inherit (upward arrow) from the Core::Substation class in CIM, mainly inheriting its properties and associations as a station container.

[0066] 5. Add the following composite associations to the rack class:

[0067]

[0068] Figure 1 In the example, the platform class (Extends::TransformerPlateform) and the three classes Extends::LogicEquipmentcontainer, Core::Substation, and Extends::SortedPole establish composite associations (solid diamonds). The association names are InnerPoles, InnerSubstations, and PoleIndexes, and their meanings are shown in the table above.

[0069] Figure 1 The lower left box is the tower class (Extends::LogicEquipmentcontainer), which represents the tower.

[0070] Next, we will combine Figure 2 , further illustrating the specific application of this embodiment.

[0071] This example describes how Figure 2 The feeder structure shown in the figure, the embodiment of the present invention provides a method for rack resource modeling. In this example, it is demonstrated how to apply the rack object to Figure 2 The feeder structure shown.

[0072] Figure 2 In the figure, the dotted rounded rectangular part TB1 is the rack. Feeder1 is the medium voltage feeder.

[0073] Specific methods include:

[0074] Step S10: Generate all topological relationships according to the CIM connection relationship.

[0075] Step S20: Generate a platform object TB1 of the TransformerPlateform type.

[0076] Step S30: Generate pole tower objects of LogicEuipment type for "Attached pole 1", "Attached pole 2" and "Attached pole 3" respectively, and establish InnerPoles association with TB1 generated in step 20. This association is a composite association type.

[0077] Step S40: Generate three SortedPole type instances, whose Index attributes are 0, 1, and 2 respectively, and whose Pole attributes are the object IDs of "Attached Pole 1", "Attached Pole 2", and "Attached Pole 3" created in step 30 respectively. The three SortedPole instances are associated with the PoleIndexes created in TB1 generated in step 20, and the association is a composite association type.

[0078] Step S50: Generate CIM Powertransformer objects for P1 and P2, and set their EuipmentContainers to the pole tower objects identified by "Attached Pole 1" and "Attached Pole 2".

[0079] Step S60: Generate two CIM Substation objects for DP1 and DP2, and establish InnerSubstations associations between DP1 and DP2 and the gantry object TB1 generated in step S20, respectively. The association is a composite association type.

[0080] Step S70: Preferably, S1, S2, F1, and F2 are modeled using normal CIM type, and the EuipmentContainer of the cable segment and terminal head objects represented by S1 and S2 and the fuse objects represented by F1 and F2 can be set to TB1.

[0081] Step S80: Preferably, the power supply feeder object of TB1 may be set to Feeder1, that is, the NormalEnergizingFeeder of TB1 may be set to Feeder1.

[0082] It can be understood that the P1 and P2 mentioned above represent two transformers inside the rack; DP1 and DP2 represent lower-level JP cabinets powered by P1 and P2 respectively; and the oval dotted frame represents the feeder Feeder1 that supplies power to the rack.

[0083] This embodiment fills the gap of no bench objects in the information system using the CIM-based model, making the information system development more efficient, the model design standardized, and the logic implementation more simplified and unified.
