Description

Technical Field

[0001] This invention relates to the field of intelligent substation technology, and in particular to a method, apparatus, equipment and medium for rapidly generating SSD files for substations. Background Technology

[0002] The System Specification Description (SSD) file for smart substations, as a crucial component of the IEC 61850 Substation Configuration Description (SCD), uses XML files to comprehensively describe the substation's primary equipment model, primary system topology, relationships between primary and secondary equipment, and functional configurations of various application systems. It serves as the "standardized digital gene" of the substation's primary system. As the fundamental model carrier for substation source-end maintenance, the SSD's application value spans the entire substation lifecycle—from design to construction, operation, maintenance, and upgrade—bringing core benefits to the power system from multiple dimensions, including technical standardization, efficiency improvement, cost optimization, and intelligent upgrades. Currently, although smart substations have been extensively constructed and put into operation in China, the practical application of SSDs in substation engineering remains limited. This is mainly due to two factors: firstly, the inherent complexity of SSD file configuration; and secondly, the overly simplistic and broad principles of the IEC 61850 standard for primary power grid modeling, resulting in weak guidance for SSD modeling and poor engineering interoperability.

[0003] With the release and application of the DL / T 1874-2018 Technical Specification for the Implementation of Modeling Engineering for Smart Substation System Description (SSD), the issues of modeling consistency and interoperability have been effectively resolved. However, currently, the mainstream SSD configuration method in the industry generally involves drawing a primary main wiring diagram based on substation design drawings using a graphic editing module, then manually associating parameters such as remote control, remote signaling, analog quantities, and protection actions for each primary device, and finally exporting it as an SSD. Another method is to enumerate typical bays and pre-set a typical bay template library, combining and splicing independent bay templates, and then manually constructing the topological connection relationships between each independent bay. Both of these methods suffer from problems such as repetitive drawing of graphics or templates, low efficiency and error-proneness of manual association, and high dependence on the technical level of the configuration personnel. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a method, apparatus, equipment and medium for rapid generation of SSD files in substations, which can significantly reduce the complexity of SSD configuration and solve the technical problems of low efficiency and error-proneness in the existing SSD file construction methods.

[0005] To achieve the above objectives, the present invention is implemented using the following technical solution: In a first aspect, the present invention provides a method for rapidly generating SSD files for substations, comprising: A set of typical design types is constructed based on the typical design selection library of substations, and a set of bus branch bay types is constructed based on the bus branch bay design selection library of substations. For each element in the set of typical design types and the set of busbar branch bay types, a corresponding primary wiring diagram template is generated using a graphical tool; Based on the aforementioned primary wiring diagram template, export the SSD format template files of typical designs and bus branch bays, along with their corresponding template feature dictionaries. Based on the actual substation primary wiring design blueprint, obtain the template features of the typical design and busbar branch bay of the actual substation, and retrieve the corresponding template file through the corresponding template feature dictionary; After instantiating the template file of the bus branch bay, merge it into the template file of the typical design under the corresponding voltage level, complete the topology relationship with the bus, and generate a full-station SSD file without primary and secondary correlation. Electrical topology feature analysis is performed on the internal conductive devices that are not associated with primary or secondary relationships in the full-site SSD file to identify the sub-types of the conductive devices; Based on the subdivision type of the conductive device, relevant secondary functional logic nodes are found from the interval IED model and associated with the corresponding conductive device to generate a full-site SSD file with primary and secondary association relationships.

[0006] Secondly, the present invention provides a device for rapidly generating SSD files in substations, comprising: The collection construction module is configured to construct a collection of typical design types based on the typical design selection library of substations, and a collection of bus branch bay types based on the bus branch bay design selection library of substations. The template generation module is configured to generate corresponding primary wiring diagram templates for each element in the typical design type set and the bus branch bay type set using graphical tools. The template export module is configured to export SSD format template files of typical designs and bus branch bays and their corresponding template feature dictionaries based on the primary wiring diagram template. The template retrieval module is configured to obtain the template features of the typical design and busbar branch bay of the actual substation based on the primary wiring design blueprint of the actual substation, and retrieve the corresponding template file through the corresponding template feature dictionary; The first generation module is configured to instantiate the template file of the bus branch bay, merge it into the template file of the typical design under the corresponding voltage level, complete the topology relationship with the bus, and generate a full-site SSD file without primary and secondary correlation relationships. The feature analysis module is configured to perform electrical topology feature analysis on the internal conductive devices that are spaced apart in the full-site SSD file without primary or secondary correlation, and to identify the sub-types of the conductive devices. The second generation module is configured to search for relevant secondary functional logic nodes from the interval IED model according to the subdivision type of the conductive device, and associate them with the corresponding conductive device to generate a full-site SSD file with primary and secondary association relationships.

[0007] Thirdly, the present invention provides an electronic device, including a processor and a storage medium; The storage medium is used to store instructions; The processor is configured to operate according to the instructions to perform the steps according to the method described above.

[0008] Fourthly, the present invention provides a computer-readable storage medium having a computer program stored thereon, which, when executed by a processor, implements the steps of the above-described method.

[0009] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: This invention provides a method, apparatus, equipment, and medium for rapid generation of substation SSD files. Starting from the general design specifications for substation primary systems, it enumerates and pre-sets typical design SSD templates and busbar branch bay SSD templates. Then, through SSD template file combination, busbar branch bay topology reconstruction, and busbar equipment topology reconstruction in typical designs, a full-station SSD file without primary and secondary relationships is generated. Finally, by employing an automatic generation technology for the relationship between primary equipment and secondary logical nodes, rapid generation of substation SSD files is achieved, significantly reducing the complexity of SSD configuration and promoting the engineering application of SSD files in the industry. It provides unified primary and secondary model data services for substation monitoring, control, centralized control, and maintenance systems, and provides crucial support for applications such as automatic primary main wiring diagram generation, automatic generation of interlocking logic, intelligent fault analysis, and explicit maintenance, bringing considerable economic and social benefits.

Detailed Implementation

[0011] The present invention will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and should not be used to limit the scope of protection of the present invention.

[0012] Example 1:

[0013] like Figures 1 to 3 As shown, this embodiment of the invention provides a method for rapidly generating SSD files for substations, including the following steps: Step S1: Construct a set of typical design types based on the typical design selection library of substations, and construct a set of bus branch bay types based on the bus branch bay design selection library of substations.

[0014] (1) The typical design selection library for substations includes the typical design selection library for 35~110kV substations, 220kV substations and 330~750kV substations.

[0015] Based on the primary wiring design specifications of each typical design in the typical design selection library, a set of typical design types is defined. The primary wiring design specifications of each typical design refer to the regulations in the typical design selection library regarding the primary wiring design requirements for substations of various voltage levels, specifying the framework information such as substation voltage levels and busbar connection methods. Typical design types are categorized by voltage level, and their design characteristics include four parameters: the number of voltage levels, the voltage values ​​of each voltage level, the busbar connection method for each voltage level, and the number of transformers. These are expressed in the form of [number of voltage levels, voltage values ​​of each voltage level, busbar connection method for each voltage level, number of transformers].

[0016] A set of typical design types for 35~110kV substations, including but not limited to {[2, 35 / 10, single bus double section / single bus three section, 2], [2, 35 / 10, internal bridge connection / single bus three section, 2], [2, 35 / 10, internal bridge connection + line transformer group / single bus three section, 3], [2, 110 / 10, double bus / single bus three section, 2], [2, 110 / 10, internal bridge connection / single bus three section, 2], [2, 110 / 10, internal bridge connection + line transformer group / single bus three section, 3], [3, 110 / 35 / 10, double bus / single bus double section / single bus three section, 2]}.

[0017] The typical design types of 220kV substations include, but are not limited to, {[3, 220 / 110 / 10, double busbar double section / double busbar / single busbar three section, 2], [3, 220 / 110 / 10, double busbar single section / / double busbar / single busbar three section, 2], [3, 220 / 110 / 35, double busbar double section / single busbar three section / single busbar double section, 2], [2, 220 / 66, double busbar single section / double busbar, 2], [2, 220 / 66, double busbar single section / double busbar / single busbar three section, 2]}.

[0018] A set of typical design types for 330~750kV substations, including but not limited to {[3, 330 / 110 / 35, three-half / double busbar / single busbar double section, 2], [3, 500 / 220 / 35, three-half / double busbar / single busbar double section, 2], [3, 500 / 220 / 66, three-half / double busbar / single busbar double section, 2], [3, 750 / 330 / 66, three-half / three-half / single busbar double section, 2], [3, 750 / 220 / 66, three-half / double busbar / single busbar double section, 2]}.

[0019] (2) Define the set of busbar branch bay types according to the design specifications for substation busbar branch bays. Since the types of busbar branch bays do not need to be distinguished by voltage level, the set of busbar branch bay types includes {double busbar bay, double busbar bay with bypass busbar bay, single busbar bay, capacitor bay, reactor bay, and station service transformer bay}.

[0020] Step S2: For each element in the typical design type set and the bus branch bay type set, use a graphical tool to generate the corresponding primary wiring diagram template.

[0021] The following are examples of generating corresponding primary wiring diagram templates using graphical tools: Using a substation primary wiring diagram drawing tool, standard primary equipment elements are added according to design specifications. All standard primary equipment elements with connection terminals are connected through terminal connection lines to generate a primary wiring diagram template with topological relationships.

[0022] A typical design primary wiring diagram template refers to a diagram based on the main wiring of a substation. Figure 1 The secondary equipment layout specifications are drawn using graphical tools to depict the entire substation's busbar equipment (including PTs), bus tie and branch equipment, main transformer equipment, and equipment on each side of the main transformer, as well as their complete topological connections, forming a large-scale substation framework model.

[0023] The busbar branch bay primary wiring diagram template refers to the busbar branch bay model formed by drawing the primary equipment (including busbars) inside the bay and their complete topological connection relationship according to the layout specifications of the primary equipment in the busbar branch bay of the substation using graphical tools.

[0024] Step S3: Based on the primary wiring diagram template, export the SSD format template files of typical designs and bus branch bays, along with their corresponding template feature dictionaries.

[0025] SSD format template files refer to intelligent substation system specification description files that conform to the IEC 61850 standard for primary modeling principles of power grids and have interoperability capabilities.

[0026] Typical design template features include the number of voltage levels, the highest voltage level value, the bus connection method for each voltage level, and the number of transformers.

[0027] The characteristics of the busbar branch bay template include branch type, wiring method, number of switches, number of disconnectors, number of capacitors, number of reactors, number of current transformers, number of voltage transformers, number of surge arresters, number of station service transformers, and number of feeder lines.

[0028] A template feature dictionary is an XML-formatted index file used to describe template features. The file records the matching features of all templates, enabling fast template retrieval and matching.

[0029] The XML description format of the typical design template feature dictionary is shown in Table 1 below, and the XML description format of the bus branch bay template feature dictionary is shown in Table 2 below.

[0030] Table 1: XML description format of typical design template feature dictionary

[0031] Table 2: XML description format of the feature dictionary for bus branch bay templates

[0032] Step S4: Based on the actual substation primary wiring design blueprint, obtain the template features of the typical design of the actual substation and the bus branch bay, and retrieve the corresponding template file through the corresponding template feature dictionary.

[0033] The primary wiring design blueprint of a substation refers to the electrical primary diagram of a substation issued by the substation design unit. It is a drawing that shows the main circuit of the substation, and it shows the connection relationship of the electrical equipment and the direction of power flow.

[0034] Typical design template features include the number of voltage levels, the highest voltage level value, the wiring method of each voltage level bus, and the number of transformers; based on these feature parameters, the corresponding typical design template can be matched from the typical design template feature dictionary to obtain the corresponding SSD template file.

[0035] The template features for busbar branch bays include branch type, wiring method, number of switches, number of disconnectors, number of capacitors, number of reactors, number of current transformers, number of voltage transformers, number of surge arresters, number of station service transformers, and number of feeder lines. Based on these feature parameters, the corresponding busbar branch design template can be matched from the busbar branch bay template feature dictionary to obtain the corresponding SSD template file.

[0036] Step S5: After instantiating the template file of the bus branch bay, merge it into the template file of the typical design under the corresponding voltage level, complete the construction of the topology relationship with the bus, and generate a full-station SSD file without primary and secondary correlation relationships.

[0037] The specific process is as follows: First, temporary dispatch numbers for each bus branch bay are sequentially arranged and preset, and bus branch bay SSD templates are instantiated to ensure that dispatch numbers for the same type of bus branch bay under the same voltage level are unique across the entire station. Then, all instantiated bus branch bay SSD templates are merged into the corresponding voltage level in the typical design SSD template file. Finally, based on the connection relationships between bus branch bays and buses in the blueprint, the bayName of the Terminal element connected to the busbar-side disconnector in the bus branch bay is replaced with the bay name of the busbar in the typical design template, generating a station-wide SSD file without primary or secondary associations.

[0038] Step S6: Perform electrical topology feature analysis on the internal conductive devices in the full-site SSD files that do not have primary or secondary correlation relationships, and identify the sub-types of conductive devices.

[0039] The specific process is as follows: Traverse all intervals in the entire SSD file that do not have primary or secondary relationships, and identify the type of interval based on the type of primary conductive device contained within the interval. Based on the type of bay, electrical topology feature analysis is performed on all switches and disconnectors under the bay to identify sub-types.

[0040] The bay types can be enumerated as the following set: {bus bay, transformer bay, main transformer high-voltage bay, main transformer medium-voltage bay, main transformer low-voltage bay, line switch bay, bus tie switch bay, sectionalizing switch bay, station service transformer bay, capacitor bank bay, reactor bay, series switch bay, series-side switch bay, bypass switch bay}.

[0041] The subcategories of switches can be enumerated as follows: {line switches, main transformer switches, sectionalizing switches, bus tie switches, bypass switches, side switches, and intermediate switches}.

[0042] Disconnectors can be further subdivided into isolating disconnectors and grounding disconnectors. The isolating disconnectors can be enumerated as follows: {bus-side disconnector, I bus-side disconnector, II bus-side disconnector, III bus-side disconnector (bypass bus disconnector), line-side disconnector, main transformer-side disconnector, side switch bus-side disconnector, side switch line (main transformer)-side disconnector, intermediate switch line-side disconnector, intermediate switch main transformer-side disconnector, PT disconnector, isolating truck, switch truck, capacitor disconnector, reactor disconnector}. The sub-types of grounding switches can be enumerated as follows: {busbar grounding switch, I busbar side grounding switch, II busbar side grounding switch, switch busbar side grounding switch, switch CT side grounding switch, line side grounding switch, main transformer side grounding switch, main transformer grounding switch, main transformer neutral point grounding switch, PT grounding switch, side switch busbar side grounding switch, side switch line (main transformer) grounding switch, middle switch line side grounding switch, middle switch main transformer side grounding switch, grounding handcart}.

[0043] Step S7: Based on the subdivision of conductive devices, find the relevant secondary functional logic nodes from the interval IED model, associate them with the corresponding conductive devices, and generate a full-site SSD file with primary and secondary association relationships.

[0044] The specific process is as follows: First, based on the completed full-site SSD file without primary and secondary associations in the SCD, import the secondary IED device model and establish the association between IEDs and bays. Then, after completing the virtual terminal configuration, name the DOIs (Directional Identifiers) of the relevant switches and disconnectors under the CTRL logical devices in the IEDs according to the standard naming format: sub-type description + "location", such as "Line Switch Location", "Bus Side Disconnector Location", and "Bus Grounding Switch Location". Finally, based on the sub-types of switches and disconnectors identified in step S6, automatically match the DOIs containing the standard names under the CTRL logical devices in the bay-associated IEDs, associate the LogicalNode to which the DOI belongs to the LNode element of the switch and disconnector, construct the primary and secondary associations, and finally generate a complete full-site SSD file with primary and secondary associations.

[0045] Taking the primary wiring design blueprint of an actual 110kV substation as an example, the method for quickly generating the substation SSD file follows these steps: Step S101: Based on the primary wiring design specifications of each typical design in the 35kV~110kV substation typical design selection library, define the typical design type set for 110kV substations. Typical design types are categorized by voltage level. Design characteristics include four parameters: the number of voltage levels, the voltage value of each voltage level, the busbar connection method for each voltage level, and the number of transformers. These are expressed in the form of [number of voltage levels, voltage value of each voltage level, busbar connection method for each voltage level, number of transformers]. The typical design type set for 110kV substations includes, but is not limited to, {[2, 110 / 10, double busbar / single busbar three-section, 2], [2, 110 / 10, internal bridge connection / single busbar three-section, 2], [2, 110 / 10, internal bridge connection + line transformer group / single busbar three-section, 3], [3, 110 / 35 / 10, double busbar / single busbar double section / single busbar double section, 2]}.

[0046] Step S102: Define the 110kV busbar branch bay type set according to the substation busbar branch bay design specifications. Since the busbar branch bay type does not need to distinguish voltage levels, the busbar branch bay type set includes {double busbar bay, double busbar with bypass busbar bay, single busbar bay, capacitor bay, reactor bay, and station service transformer bay}.

[0047] Based on steps S101 and S102, using a general substation primary main wiring diagram drawing tool and standard primary equipment elements with connection terminals, draw all busbar equipment (including PTs), bus tie and branch equipment, main transformer equipment, and equipment on each side of the main transformer, according to the requirements of the monitoring system graphical interface specifications. Connect all equipment elements through terminal connection lines to draw a 110kV typical design primary wiring diagram template and a busbar branch bay primary wiring diagram template with topological relationships. The busbar branch bay primary wiring diagram template refers to the busbar branch bay model formed by drawing the primary equipment (including busbars) inside the bay and their complete topological connection relationships using graphical tools according to the substation busbar branch bay primary equipment layout specifications.

[0048] Step S104: Based on step S103, perform graphic-model conversion, export the 110kV substation SSD template file and its corresponding template feature dictionary, and construct a pre-set SSD template library. Typical design template features include the number of voltage levels, the highest voltage level value, the busbar connection method for each voltage level, and the number of transformers. Busbar branch bay template features include branch type, connection method, number of switches, number of disconnectors, number of capacitors, number of reactors, number of current transformers, number of voltage transformers, number of surge arresters, number of station service transformers, and number of feeder lines.

[0049] The contents of the 110kV substation busbar branch template feature dictionary XML description file are as follows: <?xml version="1.0" encoding="UTF-8"?> <busbranch version="1.0.0"> <template name="单母线路" type="线路" jxType="单母" modelId="1151051235881" DIS="5" EBUS="1" CBR="1" IFL="1" SAR="1">< / template> < / busbranch> Step S105: Based on step S104, extract characteristic parameters such as the number of typical design voltage levels, the highest voltage level value, the busbar connection method for each voltage level, and the number of transformers according to the primary wiring design blueprint of the actual 110kV substation project. Based on these characteristic parameters, match the corresponding typical design template from the typical design template feature dictionary to obtain the corresponding SSD template file.

[0050] Step S106: Based on step S104, according to the primary wiring design blueprint of the actual 110kV substation project, extract the busbar branch bay types, including line branches, capacitor branches, station service transformer branches, and reactor branches. Extract the busbar branch bay wiring method, number of switches, number of disconnectors, number of capacitors, number of reactors, number of current transformers, number of voltage transformers, number of surge arresters, number of station service transformers, and number of feeder lines. Based on these characteristic parameters, match the corresponding busbar branch design template from the busbar branch bay template feature dictionary to obtain the corresponding SSD template file.

[0051] Based on steps S107, S105, and S106, firstly, temporary dispatch numbers for each bus branch bay are preset, and bus branch bay SSD templates are instantiated to ensure that the dispatch numbers for the same type of bus branch bay under the same voltage level are unique across the entire substation. Then, all instantiated bus branch bay SSD templates are merged into the corresponding voltage level in the typical design SSD template file. Finally, according to the connection relationship between bus branch bays and busbars in the blueprint, the bayName of the Terminal element of the busbar connected to the busbar-side disconnector equipment in the bus branch bay is replaced with the bay name of the busbar in the typical design template, generating a 110kV substation-wide SSD file without primary or secondary association relationships.

[0052] Step S108: Based on step S107, firstly, all bays in the entire 110kV substation SSD file without primary and secondary correlations are traversed. The specific bay type is identified based on the type of primary conducting equipment contained within the bay. Then, based on the bay type, electrical topology feature analysis is performed on all switches and disconnectors within the bay to identify sub-types. Specifically, taking a 110kV internal bridge connection substation as an example, the identified specific bay types include bus bays, bus branch bays, transformer bays, high-voltage transformer bays, low-voltage transformer bays, line bays, capacitor bays, and station service transformer bays. The specific sub-types of switches and disconnectors identified within the bays and their electrical topology features are shown in Table 3.

[0053] Table 3: Subcategories of Internal Switches and Disconnectors in 110kV Inner Bridge Substations and Their Electrical Topology Characteristics

[0054] Step S109: Based on step S108, firstly, after configuring the full-site SSD file without primary and secondary associations in the SCD, import the secondary IED device model and establish the association between IEDs and bays. Then, after completing the virtual terminal configuration, name the DOIs (Domain Identifiers) of the relevant switch and disconnector locations under the CTRL logical devices in the IEDs according to the standard naming format: sub-type description + "location", such as "Line Switch Location", "Bus Side Disconnector Location", "Bus Grounding Switch Location". Finally, based on the sub-types of switch and disconnector devices identified in step S108, automatically match the DOIs containing the standard names under the CTRL logical devices in the bay-associated IEDs, associate the LogicalNode to which the DOI belongs to the LNode element of the switch and disconnector device, construct the primary and secondary associations, and finally generate a complete substation SSD file with primary and secondary associations.

[0055] In summary, the rapid generation method for substation SSD files provided by this invention enumerates and pre-sets typical design SSD templates and bus branch bay SSD templates based on the general design specifications for substation primary systems. Through techniques such as SSD template file combination, topology reconstruction, and automatic generation of relationships between primary equipment and secondary logical nodes, the complexity of SSD configuration is significantly reduced, promoting the engineering application of SSD files in the industry and leveraging their immense value as a "standardized digital gene" for substation primary systems.
