Description

Technical Field

[0001] The present invention belongs to the technical field of distribution automation, and particularly relates to a method and system for managing operation, distribution, and dispatching models. Background Art

[0002] With the goal of meeting electricity demand, improving power supply quality, and promoting intelligent interconnection, power companies at all levels have vigorously carried out the construction of power supply service command systems. The implementation effect of the power supply service command system depends on the unified information model of the distribution network that deeply integrates the data of systems such as equipment, marketing, and dispatching. However, the objects involved in the distribution network are numerous, the designated areas are not clear, the operation modes and the primary grid framework change frequently, and the business functions are adjusted diversely, resulting in prominent problems such as overlapping of distribution network models between regions, information loss, frequent changes, and blurred boundaries. Within the region, there are also problems such as blurred boundaries, information loss, and information overlap between operation, distribution, and dispatching, especially the boundaries and their included parts of the "upstream and downstream", "left and right adjacent", and "inner and outer layers" of the distribution network cannot be described.

[0003] To form the operation, distribution, and dispatching integration model required for the power supply service command platform, the traditional method is to manually specify the model splicing points to complete the merging of the operation, distribution, and dispatching models. This requires a large amount of manpower for model maintenance and verification. Especially, with the frequent changes in operation modes and the primary grid framework, and the frequent changes in the boundaries between dispatching and between operation and distribution, it seriously affects the practicability and credibility of the operation, distribution, and dispatching integration model, and the integrated power supply service command platform based on the operation, distribution, and dispatching integration model is also difficult to play an effective role. Therefore, how to effectively manage the boundaries between operation, distribution, and dispatching has become a key issue in the construction of the operation, distribution, and dispatching integration model.

Specific implementation manners

[0067] The following further elaborates on the specific implementation manners of the present invention with reference to the accompanying drawings.

[0068] To support the unified model management requirements of the power supply service command platform, the present invention provides a distribution, operation, and dispatching model management method and system, which can automatically identify the boundary devices between dispatching, operation, and distribution, and provide distribution, operation, and dispatching model fusion services for the distribution network model resource center of the power distribution network service command platform, and provide model splitting services for distribution automation and marketing systems, thereby improving the standardization level and quality of data interaction and sharing between systems.

[0069] Embodiment 1:

[0070] A schematic diagram of the process of a distribution, operation, and dispatching model management method provided by the present invention is as Figure 1 shown, including:

[0071] Step 1: Search for the distribution automation model to obtain the boundary devices of the dispatching model, distribution automation model, and marketing model;

[0072] Step 2: Analyze the boundary devices to obtain the overlapping device information and topological information among the distribution automation model, marketing model, and dispatching model;

[0073] Step 3: Process the overlapping device information and topological information in the distribution automation model, marketing model, and dispatching model respectively, and merge the distribution automation model, marketing model, and dispatching model to obtain a complete distribution, operation, and dispatching model.

[0074] The distribution, operation, and dispatching model merging and splitting tool based on boundary devices receives model files in CIM XML format from the dispatching automation system, distribution automation system, and power consumption marketing system, automatically identifies boundary devices according to the boundary jurisdiction scope among operation, distribution, and feeder, splices the complete distribution network model based on boundary devices, and splits out a partial distribution network model containing specified devices based on boundary devices. Figure 2Modeling scope for dispatching automation system, distribution automation system and marketing system. Taking State Grid Corporation as an example, it is stipulated that the boundary point for distribution production and management is the low-voltage side of the distribution transformer at the user access point. Above the user access point to the substation outlet side belongs to distribution network production management, and below the access point belongs to marketing management. Accordingly, the model provided by the marketing system has accurate modeling information of customers and meters. The distribution transformer is equivalent to an energy power source type in the model of the marketing system, while information such as low-voltage side meters is equivalent to loads in the distribution automation system. The jurisdiction boundary between dispatching and distribution network is the feeder switch. Accordingly, the feeder switch has detailed modeling in the dispatching automation system and the distribution automation system, while the feeder is equivalent to a load in the model of the dispatching automation system. The main network substation is generally modeled to the 10kV bus in the distribution automation system, and information above 10kV is equivalent to a power source in the distribution network model. The model provided by the distribution automation system is a feeder model. A feeder model file contains one feeder. Therefore, the distribution automation system model consists of multiple feeder model files.

[0075] The implementation steps of the present invention are as follows:

[0076] Step 101: The objects described by the dispatching automation system also cover the objects involved in the transmission network of 110kV and above. Based on the operation, distribution, and dispatching model merging and splitting tool for boundary equipment, the received distribution automation model is parsed, and automatic search for boundary equipment is performed according to the jurisdiction scopes of dispatching, distribution, and marketing to form a boundary equipment set. The search steps for boundary equipment are as follows:

[0077] 101-1: The equipment container to which the equipment belongs can be traced to a circuit breaker in a substation with a voltage of 10kV, which is a dispatching and distribution boundary equipment;

[0078] 101-2: For a circuit breaker whose equipment container is not a substation, if an AC line segment can be searched at one end of the circuit breaker according to the topology and no connected AC line segment can be searched at the other end, then this circuit breaker is a feeder boundary equipment;

[0079] 101-3: A power transformer with a high-voltage side voltage of 10kV is an operation and distribution boundary equipment.

[0080] Among them, the distribution automation model includes multiple feeder models; the dispatching and distribution boundary equipment is the boundary equipment between the distribution automation model and the dispatching model, the feeder boundary equipment is the boundary equipment between feeder models, and the operation and distribution boundary equipment is the boundary equipment between the distribution automation model and the marketing model.

[0081] Figure 3 It is the search schematic diagram for the dispatching and distribution boundary equipment. The circuit breaker equipment in the substation in the CIM XML model has as Figure 4The hierarchical relationship shown. The device container to which the device belongs is the main network substation, and the circuit breaker with a voltage of 10 kV is the dispatching boundary device. First, search for the substation with the power system resource type of "main network substation" in the distribution network feeder model, and then search for the voltage level, bay, and circuit breaker in the main network substation to form Figure 4 The model hierarchical structure shown, and filter out the 10 kV circuit breakers in the substation as the pending dispatching boundary devices; check the association information between the endpoints of the pending circuit breakers and a certain feeder. If the feeder pointed to by the association has an association with the endpoint, it means that the pending circuit breaker is the boundary device between the dispatching and this feeder.

[0082] Figure 5 The search schematic diagram of the operation and distribution boundary device. Parse a feeder model CIM XML file to form Figure 6 The model hierarchical relationship shown. The power transformer with the feeder as the container and the high-voltage side voltage of 10 kV is the operation and distribution boundary device.

[0083] Figure 7 The search schematic diagram of the boundary device between feeders. The distribution automation system provides CIM XML models of multiple feeders. Parse each feeder CIM XML model file to form Figure 8 The model hierarchical relationship shown. According to the association between the substation and the feeder, and the association between the feeder and the substation, search for the power supply substation with the number of one feeder and the downstream substations with the number of multiple. The feeder tie switch is included in the feeder and its downstream substations. If the power system resource type of a certain circuit breaker is "feeder tie switch", then the circuit breaker is the boundary device between two feeders; if the power system resource type information of the circuit breaker is missing, the feeder tie switch can be determined through topological search. According to the topological search, if one end of the circuit breaker is connected to an AC line segment and the other end cannot find a connected AC line segment, then the circuit breaker is the feeder boundary device.

[0084] Step 102: For problems such as blurred boundaries and overlapping devices between multi-region models, perform topological search, analyze the overlapping device information and topological information in the boundary model, and only retain the necessary topological connection information. Among them, the region model refers to the model corresponding to a certain jurisdiction area. For distribution network management, the distribution network is divided into multiple regions, and each region can provide the distribution network model and marketing model corresponding to that region. Logically, a main network supplies power to the distribution networks of multiple regions, and there are multiple feeders in the distribution network of each region; therefore, model merging and splitting will involve a dispatching model, multiple feeder models corresponding to multiple regions and each region will have multiple feeder models, and marketing models of multiple regions. Among them, the boundary model refers to the model composed of boundary devices between operation and distribution, dispatching, and feeders.

[0085] The steps for judging overlapping information are as follows:

[0086] 102-1: Overlapping information between the feeder model and the marketing model: In the marketing model, the distribution transformer may be modeled as an equivalent energy source or a power transformer. If the distribution transformer in the marketing model is modeled as a power transformer, the name of the transformer device with a high-voltage side of 10 kV is the same as that of a certain transformer in the feeder model. A power transformer has multiple transformer windings, and each transformer winding is associated with a reference voltage. The high-voltage side is judged to be 10 kV through the reference voltage. If the distribution transformer in the marketing model is modeled as an equivalent energy source, the name of the equivalent energy source is the same as that of a certain transformer in the feeder model. Thus, the overlapping information between operation and distribution is judged.

[0087] 102-2: Overlapping information between feeder models: The feeder models are all models provided by the distribution automation system. The objects with the same ID in two feeder models are the overlapping parts.

[0088] 102-3: Overlapping information between the dispatching model and the feeder model: If the name of the circuit breaker in the feeder model is the same as that of a certain 10 kV circuit breaker in the dispatching model, then this circuit breaker is the overlapping information.

[0089] Step 103: After the model overlapping analysis, the models of multiple regions are merged and exported.

[0090] The steps for merging the feeder model and the marketing model are as follows:

[0091] 103-a1: Delete the overlapping transformer information in the marketing model, including instances of the following CIM classes: power transformer, transformer winding, and related endpoints, connection nodes, transformers, reference voltages, etc.;

[0092] 103-a2: Delete the equipment connected above 10 kV of the overlapping transformer in the marketing model, such as equivalent energy sources and related endpoints, connection nodes, substations, reference voltages, etc.;

[0093] 103-a3: Retain the equipment connected to the 380 V side of the overlapping transformer in the marketing model. For the equipment connected to the 380 V side winding of the transformer, the connection node associated with its terminal is changed to the connection node associated with the low-voltage side endpoint of the overlapping transformer in the feeder;

[0094] 103-a4: Change the reference voltage of the equipment connected below the 380 V side of the overlapping transformer in the marketing model to reference the corresponding reference voltage in the feeder model.

[0095] The steps for merging feeder models are as follows:

[0096] 103-b1: Select one of the feeder models as the base model, and delete the overlapping objects in the other feeder model, including instances of the following classes: circuit breakers, isolating switches, and related endpoints, connection nodes, substations, base voltages, etc.;

[0097] 103-b2: Connect the topological connection relationships of the line segments in the other feeder model to the devices in the base model according to the actual situation.

[0098] The steps for merging the dispatching model and the feeder model are as follows:

[0099] 103-c1: According to the boundary device information between the dispatching model and the feeder model, that is, the 10 kV circuit breaker, delete the overlapping object information in the feeder model from the 10 kV bus to the circuit breaker in the main network substation, including instances of the following classes: buses, circuit breakers, isolating switches, and endpoints, connection nodes, substations, base voltages, etc., and delete the load objects connected to the circuit breaker in the dispatching model, including instances of the following classes: loads, and endpoints, connection nodes, etc.;

[0100] 103-c2: Connect the original AC line segments connected to the circuit breaker in the feeder model to the circuit breaker in the dispatching model.

[0101] Step 104: The integrated operation, dispatching, and distribution model in the distribution network model resource center can export a partial model containing the given device ID based on the device ID and the boundary device. Conduct a depth search from the nodes corresponding to these IDs in the topological relationship diagram, and search for other devices connected to these devices until the searched device is a "boundary device", then stop.

[0102] Take Figure 9 the process of depth search in the model splitting shown as an example, Figure 9In the following, EQ1 to EQ5 represent devices 1 to 5; TE1 and TE2 are the two endpoints of EQ1, TE3 is the endpoint of EQ2, TE4 is the endpoint of EQ3, TE5 is the endpoint of EQ4, and TE6 is the endpoint of EQ5; CN1 and CN2 represent connection nodes, where the endpoints associated with CN1 include TE2, TE3, TE4, and TE5, and the endpoints associated with CN2 include TE1 and TE6. Assume that the node corresponding to the given device ID is EQ1, and then perform a depth search in both the left and right directions. Assume starting from the left first, the search path is EQ1 -> TE1 -> CN2 -> TE6 -> EQ5. If the identifier of EQ5 is a boundary device, the depth search in this direction stops; then start the search from the right of EQ1, and the search path is EQ1 -> TE2 -> CN1 -> TE3 -> EQ2 (the identifier of EQ2 is a boundary device, stop) -> CN1 -> TE4 -> EQ3 (the identifier of EQ3 is a boundary device, stop) -> CN1 -> TE5 -> EQ4 (the identifier of EQ4 is a boundary device, stop). After all the paths on both sides of EQ1 are searched, export the searched devices to an XML file, including the endpoints of these devices and the connection nodes associated with the endpoints.

[0127] The model export unit is configured to stop the search when the boundary device is found, to obtain and export the partial model containing the device ID.

[0128] Embodiment 3:

[0129] The following gives an example of the same specific application of the operation, distribution, and dispatching model management.

[0130] The operation, distribution, and dispatching model management system is integrated into an operation, distribution, and dispatching model merging and splitting tool based on boundary devices, and is applied in the distribution network model resource center of the power supply service command platform, as Figure 12 shown.

[0131] The dispatching automation system, distribution automation system, and power consumption marketing system respectively model the devices within their jurisdiction, and then there is overlapping information among the three. The State Grid Corporation stipulates that the production and management work takes the user access point as the demarcation point. Above the user access point to the substation outlet side belongs to the distribution network production management, and below the access point belongs to the marketing management. Therefore, generally, the low-voltage side of the distribution transformer, which is the user access point, is used as the demarcation between operation and distribution. The scope of the feeder generally starts from the substation outlet side to the tie switch, and the substation feeder switch can be selected as the demarcation point between dispatching and distribution. Between two feeders connected by a tie switch, the tie switch can be used as the demarcation between the two feeders. All three systems can provide model files.

[0133] 1) Model files of the distribution automation, dispatching automation, and power consumption marketing systems;

[0134] 2) A set of boundary devices automatically recognized by the tool;

[0135] 3) Tool-generated operation, distribution, and dispatching splicing model.

[0136] The downstream information includes:

[0137] 1) The full operation, distribution, and dispatching model of the distribution network model resource center;

[0138] 2) The set of boundary devices stored in the distribution network model resource center;

[0139] 3) The split model generated by the tool.

[0140] The operation, distribution, and dispatching model merging and splitting tool based on boundary devices receives model files from the distribution automation, dispatching automation, and power consumption marketing systems. The tool receives the CIM XML model file of distribution automation, identifies the boundary devices, and sends the identified boundary devices to the distribution network model resource center for unified storage of boundary devices; the tool receives multiple CIM XML model files of distribution automation, dispatching automation, and power consumption marketing systems for overlapping analysis of multi-region models; the tool receives multiple CIM XML model files of distribution automation, dispatching automation, and power consumption marketing systems, and merges the full operation, distribution, and dispatching model according to the overlapping analysis results and the definition of boundary devices, and sends it to the distribution network model resource center for storage; the tool splits the parts of the model that they are interested in for the distribution automation, dispatching automation, and power consumption marketing systems according to the definition of boundary devices.
