[0032] Example 1

[0033] Figure 1This is a flowchart illustrating an automatic SCD generation method for smart substations provided in Embodiment 1 of the present invention. This method is applicable to the automatic generation of SCD files in smart substations. The method can be executed by an automatic SCD generation system for smart substations. The device can be implemented by software and / or hardware and is generally integrated into an electronic device. In this embodiment, the electronic device includes, but is not limited to, devices such as computers.

[0034] like Figure 1 As shown in Embodiment 1 of the present invention, an automatic SCD generation method for intelligent substations includes the following steps:

[0035] S110. Construct a primary wiring diagram, which includes the topological relationships in the smart substation.

[0036] A primary wiring diagram is a standardized schematic diagram used in a power system to show the connection relationships of electrical equipment (such as circuit breakers, disconnectors, transformers, busbars, etc.) in a primary circuit. Topology refers to the physical structure and logical connection relationships formed by the electrical connections of primary electrical equipment (such as circuit breakers, disconnectors, transformers, busbars, etc.).

[0037] In this embodiment, a main wiring diagram can be constructed first, which may include the topological relationships in the smart substation.

[0038] In one embodiment, constructing the primary wiring diagram includes: designing a topology based on primary equipment; defining primary bay attributes for primary bays in the topology, wherein the primary bay attributes include at least the bay number of the primary bay; determining the scheduling name of the primary equipment and mapping and associating the scheduling name with the bay number of the primary bay corresponding to the primary equipment; and determining the number of windings and polarity of all current transformers (CTs) in the topology, as well as the number of windings and secondary ratings of all voltage transformers (PTs).

[0039] Primary equipment refers to electrical equipment that directly participates in the production, transmission, distribution, and use of electrical energy in a power system. Its function is to realize the conversion, transmission, and control of electrical energy, directly bearing the voltage, current, and power of the power system under normal or fault conditions. A primary bay can be an independent functional unit in a power system composed of primary electrical equipment (such as circuit breakers, disconnectors, instrument transformers, lines, or transformers). It can be used to complete specific tasks of electrical energy transmission, distribution, or transformation, and usually corresponds to a specific power circuit (such as a line bay, transformer bay, or busbar equipment bay). Primary bay attributes refer to specific attribute values ​​describing the characteristics, functions, and operating parameters of a primary bay, used to clarify the electrical characteristics, equipment configuration, and operating logic of the bay. Bay number can be a unique identifier for a primary bay. Dispatch naming can be a unique name and number assigned to primary electrical equipment, used to clarify the equipment's identity, function, and topological relationship in the system. The winding of a current transformer (CT) refers to the coil wound with insulated wire inside the current transformer, and the polarity of the CT refers to the relative direction of the current between the primary and secondary windings during electromagnetic induction. The winding of a voltage transformer (PT) can refer to the coil inside the voltage transformer used to achieve electromagnetic induction conversion from high voltage on the primary side to low voltage on the secondary side. The secondary rating can refer to the standard voltage value and capacity of the PT secondary winding during normal operation.

[0040] In this embodiment, the primary equipment can be used to design the topology relationship and define the primary interval attribute of the primary interval in the topology relationship. The scheduling name of the primary equipment is mapped and associated with the interval number of the primary interval corresponding to the primary equipment. The number of windings and polarity of all current transformers (CTs) in the topology relationship, as well as the number of windings and secondary rating of all voltage transformers (PTs) are determined, thereby completing the construction of the primary main wiring diagram.

[0041] For example, Figure 2 A schematic diagram of a primary wiring diagram provided in an embodiment of the present invention, such as... Figure 2As shown, the design of a primary topology can include necessary primary equipment such as buses, transformers, lines, circuit breakers, and instrument transformers. Defined primary bay attributes can include voltage level, wiring type, bay type, and bay number. Primary bay attributes can be used to generate IED names and configuration parameters, and also provide configuration parameters for the automatic generation of Internet Protocol (IP) addresses and virtual loops. Information such as the scheduling name (project name) of primary equipment can also be defined, and a mapping relationship can be established between the scheduling name (project name) and the primary equipment bay number. The scheduling name is mainly used for IED naming and the description of the instantiated IED when adding it. The number and polarity of the CT windings are defined; this parameter is mainly used for whether the current is connected with positive or reverse polarity when configuring virtual loops. The number and secondary ratings of the PT windings are defined; this parameter is mainly used for selecting the cascaded voltage when configuring virtual loops—whether to cascade A-phase voltage or three-phase voltage.

[0042] S120. Associate the intelligent electronic devices (IEDs) in the substation configuration description SCD file with the corresponding bay in the main wiring diagram.

[0043] In this embodiment, IEDs in the SCD file can be automatically or manually associated with the corresponding bays in the main wiring diagram. For example, the manual addition method involves setting the bay number, equipment type, set type, voltage level, bay type, and branch phase number of the IED when adding it to a bay. The automatic addition method involves configuring secondary equipment groups to the maximum extent possible according to the voltage level and bay type of each bay. For example, in a 500kV circuit breaker bay, two sets of circuit breaker protection, two sets of circuit breaker acquisition and execution units, and one set of circuit breaker measurement and control are automatically configured.

[0044] In one embodiment, associating the intelligent electronic devices (IEDs) in the substation configuration description SCD file with the corresponding bays in the main wiring diagram includes: obtaining each primary bay in the main wiring diagram; for each primary bay, configuring a secondary equipment group with the goal of maximizing the voltage level and bay type of the primary bay, the secondary equipment group including one or more IEDs, the parameters of the IED including bay number, equipment type, set type, voltage level, bay type and branch phase number; and associating the secondary equipment group with the primary bay.

[0045] The voltage level refers to the rated voltage at which the IED is designed to operate. The IED type can include incoming line IEDs, outgoing line IEDs, bus tie IEDs, transformer IEDs, capacitor / reactor IEDs, and PT IEDs. The secondary equipment group refers to an organic combination of various devices that monitor, control, protect, regulate, and communicate the operating status of the primary system. Indirect control of the power system is achieved through signal acquisition, processing, and command transmission from the primary equipment. The IED number is a unique identifier for the primary electrical IED to which it belongs. The equipment type can be a category based on the IED's function. The protection set can be for dual or triple protection configurations, identifying the number of protection sets to which the IED belongs, used to distinguish equipment groups in redundant systems. The IED voltage level can be the rated voltage level of the primary system served by the IED. The IED IED IED type can be the functional attribute of the primary IED to which it belongs. The branch phase number can be the number identifying the phase (A / B / C phases) or branch circuit associated with the IED. For example, the branch phase number can refer to the branch number (branch one, branch two) on the low-voltage side of the transformer, the phase number of the transformer body acquisition and execution unit (phase A, phase B, phase C), and the phase number of the high-resistance body acquisition and execution unit.

[0046] In this embodiment, for a primary bay in the main wiring diagram, the goal is to maximize the voltage level and bay type of the primary bay. Secondary equipment groups can be configured, and then the secondary equipment groups can be associated with the primary bay, so that a single primary bay or the entire substation can support more types of bays.

[0047] In this embodiment, after adding all IED devices to the substation, the IED name and description can be automatically generated. The IED name can be generated using a 6-layer structure, consisting of device type, bay type, voltage level, bay type, bay number, and branch phase number. The IED description is generated in the order of voltage level, bay type, and device type. For example, in a 500kV circuit breaker bay, one IED device is added. The bay number is 1, the voltage level is 500kV, the device type is protection, the bay type is circuit breaker, and the type is the first set; the branch phase number is none, and the dispatch name is 5011 circuit breaker. Then the IED name is P_B5001A, and the IED description is the first protection set for the 500kV 5011 circuit breaker.

[0048] S130. Generate IED configuration parameters based on the topology and the IED.

[0049] The IED configuration parameters may include common parameters, virtual terminal connection parameters, extended adaptability parameters, and safety automatic configuration parameters.

[0050] In this embodiment, IED configuration parameters for all IED devices in the site can be generated through topology relationships and IEDs.

[0051] In one embodiment, the IED configuration parameters include one or more of the following: common parameters, virtual terminal connection parameters, extended adaptability parameters, and safety automatic configuration parameters; wherein, the common parameters include the IED's bay number, voltage level, wiring method, set type, and virtual local area network (VLAN) tag; the virtual terminal connection parameters include connecting bus groups, connecting circuit breaker bays, protection configuration methods, and branch or tributary connection relationships; the safety automatic configuration parameters include connecting safety automatic device objects, tripping and closing tributary numbers.

[0052] In this embodiment, common parameters refer to parameters of common attributes of the IED, including the IED's bay number, voltage level, wiring method, set, and Virtual Local Area Network (VLAN) tag. Virtual terminal connection parameters can include connection to bus groups, connection to circuit breaker bays, protection configuration methods, and branch or tributary connection relationships; these parameters can be used to describe connection relationships with other IED devices. Expanded adaptability parameters can be used to describe parameters of bay protection devices or new independent protection or safety automatic devices whose connection objects are common datasets; adaptability is improved by changing the sending dataset of the subscribed object. Safety automatic configuration parameters can include the connected safety automatic device object, tripping and closing tributary numbers; these parameters can be used to describe the connection relationships between various configuration-free secondary devices and safety automatic devices.

[0053] This embodiment defines and classifies various parameters of primary equipment and IED equipment in detail, such as primary interval attributes, CT / PT winding parameters, and common parameters of IED equipment, so that the equipment parameter configuration is systematic, reducing ambiguity and arbitrariness, and further improving the standardization of configuration.

[0054] For example, Figure 3 A schematic diagram of a three-way wiring provided in an embodiment of the present invention is shown below. Figure 3 As shown, taking the side circuit breaker bay closest to busbar 1 as the center, the topological relationship between this side circuit breaker bay and the adjacent line bay, main transformer bay, and circuit breaker bay is as follows: busbar group 1 is named bus I, busbar group 2 is named bus II, the circuit breaker bay closest to bus II is the side circuit breaker bay, and the line or main transformer bay closest to bus II is the side bay.

[0055] Based on the topology, IED configuration parameters are generated, taking P_B5001A as an example:

[0056] For configuring common parameters, the following generation strategies can be adopted: The local interval number can be taken from the current interval number. The set type can be taken from the current equipment set type, set when adding IED devices. The wiring type can be taken from the current interval wiring type, specifically based on the primary topology analysis. The voltage level can be taken from the current interval voltage level parameter, set in the main wiring diagram. The VLAN tag can be taken from the current device VLAN tag. Connecting circuit breaker intervals can be configured through the primary topology structure. For example, the generation strategy for connecting the edge 1 circuit breaker interval is: according to the primary topology structure, the edge 1 circuit breaker is not connected, so the value is 0. The generation strategy for connecting the edge 2 circuit breaker interval is: according to the primary topology structure, the edge 2 circuit breaker interval is connected, the interval number of the edge 2 circuit breaker is 2, and the value is 2. The generation strategy for connecting the edge 1 bus group is: according to the primary topology structure, the edge 1 bus interval interval number is 1, the edge circuit breaker interval is connected to the edge 1 bus interval, and the value of the connected edge 1 bus group is 1. The generation strategy for connecting the Side 1 busbar group involves setting the branch number of the side circuit breaker bay to 1 and the branch number of the Side 1 busbar protection to 1 when adding an IED. The Side 1 circuit breaker uses an expanded dataset, which defaults to 0. The expanded adaptability parameter is generally set to 0 by default, but can be manually specified when adaptation is required. The configuration of safety automatic parameters can be determined by whether the substation is connected to safety automatic devices; this implementation does not impose such limitations. Table 1 below shows the configuration parameters for the first set of circuit breaker protection P_B5001A in the side circuit breaker bay.

[0057] Table 1. Configuration parameters of the first circuit breaker protection P_B5001A in the side circuit breaker bay.

[0059]

[0060] S140. Associate the ICD file of the IED with the SCD file, import the loop configuration subscription relationship table and the table of primary equipment interval classification, quantity and starting address of the whole station, and automatically generate subnet, communication parameter configuration, port configuration and virtual loop configuration in combination with the IED configuration parameters to complete the configuration of the SCD file.

[0061] The Intelligent Electronic Device Capability Description (ICD) file is one of the core configuration files in a power system based on the IEC 61850 standard. It's a text file that provides a standardized description of the IED's functions, interfaces, data models, and communication parameters; different IEDs can correspond to the same ICD file. The circuit configuration subscription relationship table is a standardized configuration table used in smart substations of power systems to describe the signal transmission logic of secondary circuits. It records the signal subscription-publishing relationship between IEDs based on the IEC 61850 standard and is a core component of the SCD. The substation primary equipment bay classification, quantity, and starting address table is a standardized table used in the design and configuration of power system substations to standardize the division, quantity statistics, and address coding of primary equipment bays. This table can describe the maximum number of bays of each voltage level and type, the maximum configuration of secondary equipment for each bay type, the number of datasets for each type of secondary equipment, the starting address of the Application Identifier (APPID), and the offset address of the first set of secondary equipment. The circuit configuration subscription relationship table can describe the standard virtual circuit connection method for configuring virtual circuit IEDs.

[0062] In this embodiment, the ICD file can be associated, and the loop configuration subscription relationship table, the classification, quantity and starting address table of primary equipment intervals (groups) of the entire station can be imported to automatically generate subnets, communication parameter configurations, port configurations, virtual loops, etc., and complete the SCD file configuration.

[0063] In one embodiment, associating the IED's ICD file with the SCD file, importing the loop configuration subscription relationship table and the table of primary equipment bay classification, quantity, and starting address for the entire substation, and automatically generating subnets, communication parameter configurations, port configurations, and virtual loop configurations based on the IED configuration parameters includes: obtaining the ICD file corresponding to the IED and associating the ICD file with the SCD file; dividing the communication network of the smart substation into subnets to obtain different subnets; allocating all IED devices in the substation to the corresponding subnets; configuring the station control layer communication parameters for different bays in the main wiring diagram; automatically configuring the process layer communication parameters for different bays based on the table of primary equipment bay classification, quantity, and starting address for the entire substation, combined with the IED configuration parameters; and completing the virtual loop configuration between each IED and the virtual loop receiving port configuration based on the loop configuration subscription relationship table and the IED configuration parameters.

[0064] The communication parameter configuration includes the configuration of station control layer communication parameters and process layer communication parameters. Station control layer communication parameters refer to the key parameters that need to be configured for station control layer equipment (such as monitoring hosts, remote control devices, data servers, etc.) in the substation automation system during network communication. Process layer communication parameters refer to the key parameters that need to be configured for process layer equipment in the substation automation system during communication.

[0065] In this embodiment, ICD files can be associated manually or automatically. For example, an ICD file can be manually selected, or automatically associated based on manufacturer, model, version, checksum, substation type, compatible voltage level, compatible wiring method, compatible bay, compatible equipment type, compatible sampling method, and selected function information. When dividing the subnets, this embodiment can divide the subnets into Manufacturing Message Specification-A (MMS-A), Manufacturing Message Specification-B (MMS-B), Sampled Values ​​(SMV), and Generic Object Oriented Substation Event (GOOSE) networks. Then, all IED devices in the station will be assigned to the subnets, and the station control layer communication parameters and process layer communication parameters will be configured automatically, as well as the virtual loop and receiving port configurations.

[0066] In this embodiment, the station control layer communication parameter configuration may include IP address, subnet mask, and gateway parameters. The subnet mask defaults to 255.255.0.0, and the gateway parameter defaults to 0.0.0.0. The IP address generation principle can be as follows: based on the subnet type, select the corresponding IP address class, obtain the IED's voltage level, and the order in which the IEDs were added, and automatically generate the IED's IP address. The order in which the IEDs were added refers to the order in which all IED devices in the station are configured; each subnet can be configured with multiple IEDs.

[0067] This invention provides an automatic SCD generation method for smart substations, comprising: constructing a primary wiring diagram, the primary wiring diagram including the topology of the smart substation; associating the Intelligent Electronic Devices (IEDs) in the substation configuration description (SCD) file with the corresponding bays in the primary wiring diagram; generating IED configuration parameters based on the topology and the IEDs; associating the ICD files of the IEDs with the SCD file, importing a loop configuration subscription relationship table and a table of primary equipment bay classification, quantity, and starting address for the entire substation, and automatically generating subnet, communication parameter configuration, port configuration, and virtual loop configuration based on the IED configuration parameters to complete the SCD file configuration. This method, through automated and standardized configuration, significantly improves the generation efficiency and quality of SCD files for smart substations, enhances the system's security, adaptability, and stability, simplifies the operation process, reduces maintenance costs, and provides strong support for the safe and stable operation of smart substations, solving the problem of existing technologies being unable to automatically generate standardized SCD files.

[0068] Based on the above embodiments, modified embodiments of the above embodiments are proposed. It should be noted that, in order to keep the description brief, only the differences from the above embodiments are described in the modified embodiments.

[0069] In one embodiment, the process layer communication parameters include at least the Media Access Control (MAC) address, Application Identifier (APPID), Virtual Local Area Network (VLAN) Identifier (VLAN-ID), Virtual Local Area Network (VLAN-Priority), Minimum Time (MinTime), and Maximum Time (MaxTime). The automatic configuration of the process layer communication parameters for different intervals based on the station's primary device interval classification, quantity, and starting address table, combined with the IED configuration parameters, includes: using the VLAN tag value in the IED configuration parameters as the VLAN-ID; configuring the VLAN-Priority using the default method; using the MinTime and MaxTime of the corresponding control block in the ICD file associated with the IED as the corresponding MinTime and MaxTime; determining the APPID of each control block of the IED based on the station's primary device interval classification, quantity, and starting address table, combined with the interval number, set type, and voltage level of the IED configuration parameters; and generating a MAC address based on the fixed bytes of each control block of the IED and the last two bytes of the corresponding APPID.

[0070] In this embodiment, the process layer communication parameters include at least the Media Access Control Address (MAC), Application Identifier (APPID), Virtual LAN Identifier (VLAN-ID), Virtual LAN Priority (VLAN-Priority), Minimum Time (MinTime), and Maximum Time (MaxTime). This embodiment can batch generate the MAC addresses and APPID parameters of each dataset for secondary device groups based on the primary device interval classification, quantity, and starting address table for the entire site. This allows for rapid configuration of communication parameters for a large number of devices, avoiding the tedious process of manually configuring each device individually and further improving configuration efficiency.

[0071] In this embodiment, the MAC address and APPID of each dataset of secondary equipment can be calculated based on the primary equipment interval classification, quantity, and starting address table, combined with the interval number, set type, and voltage level of the IED configuration parameters, to complete the process layer communication parameter configuration. The specific configuration method is as follows:

[0072] VLAN-ID is obtained from the VLAN tag value in the IED configuration parameter table, and VLAN-Priority is 4 by default;

[0073] MinTime and MaxTime are the MinTime and MaxTime values ​​of the corresponding control block in the ICD file associated with the IED;

[0074] The APPID generation principle is as follows: Based on the classification, quantity, and starting address table of primary equipment bays throughout the station, and combined with the bay number, set type, and voltage level of the IED configuration parameters, the APPID of each control block of the secondary equipment is calculated.

[0075] APPID=A+(N-1)*B+C+D*(S-1)+E;

[0076] Where A is the starting address of the interval APPID, B is the number of secondary device addresses within the interval, C is the offset address of the first set of secondary devices, D is the number of secondary device control blocks, E is the sequence number of the secondary device control blocks, N is the interval number, and S is the set type. In this embodiment, A, B, C, and D can be determined by the voltage level and interval type.

[0077] The MAC address generation principle is as follows: the first 4 bytes of the GOOSE control block MAC address are fixed as 01-0C-CD-01, the first 4 bytes of the SV control block MAC address are fixed as 01-0C-CD-04, and the last two bytes of the GOOSE control block and SV control block are set to be consistent with the APPID address; that is, MAC = 01-0C-CD-01-27-24.

[0078] As shown in Table 2, process layer communication parameters can be configured by combining the classification, quantity, and starting address table of primary equipment intervals for the entire station.

[0079] Table 2. Classification, Quantity, and Starting Address of Primary Equipment Intervals for the Entire Station

[0080]

[0081]

[0082] In one embodiment, the step of configuring virtual loops and virtual loop receiving ports between IEDs based on the loop configuration subscription relationship table and the IED configuration parameters includes: configuring virtual loops between IEDs according to the IED configuration parameters, the loop configuration subscription relationship table, expressions, and interval number matching relationships; obtaining port mapping information for all IED devices, the port mapping information including the relationship between interface numbers and logical and physical ports; finding the logical and physical ports corresponding to the IED devices according to the loop configuration subscription relationship table and the interface numbers between IEDs; and configuring the receiving ports of the virtual loops based on the logical and physical ports corresponding to the IED devices.

[0083] The interface number can refer to the interface number between other IEDs, i.e., which port the IED uses to connect to other IEDs, and the corresponding port number. The physical port can be the port of the actual IED device, such as 7-A. The logical port can be the port in the corresponding ICD file model of the IED, such as 1-A. The expression can represent the conditions that the virtual loop must meet to be effective. If no expression is provided, it is effective by default; if an expression is provided, the loop is effective when the expression is true. When the expression calculation process requires merging operations, merging calculation supports arithmetic and logical operations. The merged expression consists of aliases, constants, and operators. The calculation variables in the expression are represented by identifiers in the standard template.

[0084] In this embodiment, the loop configuration subscription relationship table describes the standard virtual loop connection method for all IEDs requiring virtual loop configuration, including protection, multi-functional measurement and control, acquisition and execution units, and stability control. During virtual loop configuration and virtual loop receiver port configuration, virtual loops between IEDs can be configured based on IED configuration parameters, combined with the loop configuration subscription relationship table, expressions, and interval number matching relationships. Port mapping information of the IED devices can be obtained. Based on the loop configuration subscription relationship table and the interface sequence numbers between IEDs, the logical and physical ports corresponding to the IED devices are found. The receiver port configuration of the virtual loop is then completed based on the logical and physical ports corresponding to the IED devices.

[0085] In this embodiment, the virtual loop configuration is based on the IED configuration parameters, adapts to the loop configuration subscription relationship table, and matches the virtual loops to be activated according to the expression and interval number matching relationship to complete the virtual loop configuration. The receiving port configuration obtains the port mapping information of the actual IED device, including the relationship between the interface number and the logical and physical ports. Based on the interface number defined between IEDs in the loop configuration subscription relationship table, the port mapping information of the actual IED device is found, and the virtual loop receiving port configuration of the port is completed.

[0086] For example, Table 3 is a loop configuration subscription relationship table, which describes the IED1 name, IED1 virtual terminal description 1, loop type, IED2 name, IED2 virtual terminal description 2, activation strategy, opposite side voltage level, and opposite side interval number, so as to realize the description of all loops to be subscribed to by the target IED and their activation strategies.

[0087] Table 3. Loop Configuration Subscription Relationship Table

[0088]

[0089]

[0090] Wherein, IED1 represents the standard IED attribute of the target IED. IED2 represents the external virtual loop IED attribute to be subscribed to for the target IED. IED1 Virtual Terminal Description 1 is the standard description of the internal virtual terminal to be subscribed to, and IED2 Virtual Terminal Description 2 is the standard description of the external virtual terminal to be subscribed to. IED2 Voltage Level indicates that the voltage level parameter of the IED on the other side should be consistent with the set voltage level. IED2 Interval Number indicates that if the local interval number of the IED on the other side is the target value and its IED attribute matches the attribute of IED2, then the IED is adapted to this virtual loop. If the interval number on the other side exists, it is a mandatory condition. IED2 Branch Number indicates that if the branch number parameter of the IED on the other side is the target value, the corresponding IED is adapted.

[0091] When automatically configuring communication parameters at the station control layer and process layer, for example, if the manufacturer of P_L5001B is set to XXXX, the model is PCS-921A-DA-GZK, the version is V6.01, and the checksum is 02447718, then the ICD file will be automatically selected as PCS-921A-DA-GZK-V6.01-02447718.icd.

[0092] For example, the IP address of MMS-A network P_B5001A is generated as follows: The MMS-A network class address format is 172.16.YN. "Y" can be generated according to the voltage level: 50 for 500kV, 33 for 330kV, 222 for 220kV, 11 for 11 for 11 for 66kV, 66 for 35kV, 35 for 10kV, and 99 for public devices. "N" is generated according to the IED order, starting from 21. From the IED configuration parameters in the table above, we know the voltage level is 500kV, the IED order is 1, and the IP address is 172.16.50.21.

[0093] When calculating the APPID, for example, to calculate the APPID of the first control block P_B5001AGOOSE, according to the classification, quantity and starting address table of primary equipment intervals in the whole station, the starting address A of the APPID is 10020, the number of secondary equipment addresses within the interval B is 18, the offset address C is 0, and the number of control blocks D is 1.

[0094] Based on the configuration parameter table of P_B5001A mentioned above, we know that the interval number is 1 and the set number is 1. Calculate the APPID of the first control block of GOOSE. Therefore, the dataset device dataset sequence number is 0. The calculated APPID is 10020 + (1-1)*18 + 0 + 1*(1-1) + 0, APPID = 10020, which is 2724 in hexadecimal.

[0095] The MAC address generation principle is as follows: the first 4 bytes of the GOOSE control block MAC address are fixed as 01-0C-CD-01, the first 4 bytes of the SV control block MAC address are fixed as 01-0C-CD-04, and the last two bytes are consistent with the APPID address; MAC = 01-0C-CD-01-27-24.

[0096] This embodiment achieves full automation from the construction of the primary wiring diagram, configuration of IED devices, parameter generation to automatic configuration of virtual circuits, greatly reducing manual operation steps, saving configuration time, and improving work efficiency.
