[0075] In the Bay interval configuration module, the attribute value "1E" of the Bay name is extracted as the interval name (Bay name), and the attribute value "220KV line" of the desc is extracted as the interval description (desc).

[0076] For the lower-level IED Name and the attribute values "I_L2201" and "220KV line intelligent terminal" of the desc with the interval name "1E", they are used as the device name (IED name) and device description (desc) included in the interval respectively.

[0077] Step 2: Associate the device information and virtual terminal information in the SCD model file with the device elements and sub-device elements of the substation physical logic model file, and load the loop functions associated with the virtual terminal information in the SCD model file into the sub-device element functions of the associated sub-device elements in the substation physical logic model file to generate an intelligent archiving model file.

[0078] The substation physical logic model file describes the substation's compartment elements, cubicle elements, device elements, sub-device elements, in-cabinet connection relationships, interval elements, and physical loop information.

[0079] The attributes of the compartment elements include: compartment number (Region Name), compartment description (Region desc);

[0080] The compartment elements include multiple cubicle elements (Cubilcle).

[0081] The cubicle element, an assembly of devices installed in the compartment element, is used to carry and protect various electrical devices and their connecting wires to form a functional unit. The attributes of the cubicle element include: cubicle number (Cubicle Name) and cubicle description (Cubicledesc). The cubicle element includes device elements (Device) and in-cabinet connection relationships (Core);

[0082] The device element is the basic unit that makes up the cubicle and has specific electrical or mechanical functions, such as circuit breakers, transformers, etc. The attributes of the device element include: device name (Device Name), device description (Device desc), device type (Device Type), device unique identification code (Device IEDName); The device element includes multiple sub-device elements.

The attributes of the sub-device element (SubDevice) include the sub-device element name (SubDevice name) and the sub-device element function (SubDevice Fuction).

[0084] The in-cabinet connection relationship (Core) describes the connection relationship between sub-device elements in the cubicle, including: the connection relationship number (Core no), the device at the A-end connection point (LinkA Device), the sub-device at the A-end connection point (LinA SubDevice), the device at the in-cabinet B-end connection point (LinkB Device), and the sub-device at the in-cabinet B-end connection point (LinB SubDevice).

[0085] The bay element describes the secondary protection devices related to the primary equipment in the substation, such as protection devices, measurement and control devices, etc. The attributes of the bay element include: bay name (Bay No), bay description (Bay name), bay type (Bay Type), and bay voltage level (Bay Voltage);

[0086] The bay element includes the cubicle name (Cubicle name) and device name (Device) of the cubicles it contains

[0087] The physical circuit information describes the specific connection information and functional description information of the physical circuits in the substation, including the circuit number (Circuit no) and the corresponding circuit information. The circuit information includes the cubicle at the A-end connection point (LinkACubicle), the device at the A-end connection point (LinkA Device), the sub-device at the A-end connection point (LinkA SubDevice), the cubicle at the inter-cabinet B-end connection point (LinkB Cubicle), the device at the inter-cabinet B-end connection point (LinkB Device), the sub-device at the inter-cabinet B-end connection point (LinkB SubDevice), and the physical circuit function description (Circuit Function);

[0088] Associate the device information in the SCD model file with the device elements in the substation physical logic model file. The association method is as follows: The bay name of the bay information to which the device information in the SCD model file belongs is the same as the bay no of the bay element to which the device element in the substation physical logic model file belongs. The device description (desc) and device type of the device information in the SCD model file are the same as the device type (Device Type) of the device description (Device desc) of the device element in the substation physical logic model file. Then, assign the IED name of the device information to the Device IEDName of the corresponding device element.

[0089] Associate the virtual terminal information in the SCD model file with the sub-device elements in the substation physical logic model file. The association method is as follows: The virtual terminal name in the virtual terminal information of the SCD model file is the same as the sub-device element name of the sub-device element in the substation physical logic model file. Find the loop function corresponding to the virtual terminal name in the virtual terminal physical loop connection relationship, and assign the loop function to the SubDevice Fuction of the sub-device element.

[0090] So far, by assigning the Device IEDName of the device elements and the SubDevice Fuction of the sub-device elements in the substation physical logic model file through the SCD model file, the intelligent archiving model file is obtained.

[0091] In this embodiment, the bay name “1E” of the bay information to which the device information belongs is the same as the bay no “IE” of the bay element to which the device element belongs. The device description “220kV line intelligent terminal” of the device information is the same as the device description “220kV line intelligent terminal” of the device element. And the device type of the device information and the device element is “I”. Assign the IED name “I_L2201” of the device information to the Device IEDName of the corresponding device element. Further, find the virtual terminal name “X6-a2” and the sub-device element name that are the same. Fill the loop function “breaker disconnector position” corresponding to the virtual terminal name “X6-a2” into the SubDevice Fuction of the sub-device element to obtain the intelligent archiving model file.

[0092] Step 3: In the design drawings, identify the cabinet diagram blocks, identify the cabinet names corresponding to the cabinet diagram blocks, identify each device graphic element and the device graphic element name contained in the cabinet diagram blocks, search for the loop description diagram blocks near the cabinet diagram blocks, and identify the loop descriptions corresponding to the device graphic elements in the cabinet diagram blocks in the loop description diagram blocks.

[0093] The device graphic elements in the cabinet diagram blocks and the loop descriptions in the loop description diagram blocks are horizontally aligned. By judging whether all the device graphic elements in the cabinet diagram blocks have loop descriptions that are horizontally position-aligned, if the above-mentioned position-aligned loop descriptions are all in one diagram block frame, then the above diagram block frame is the loop description diagram block near the cabinet diagram block, and the loop descriptions in the loop description diagram block are the loop descriptions corresponding to the device graphic elements in the cabinet diagram block.

[0094] In this embodiment, the cabinet diagram block with the cabinet name of 1P needs to be found. In the cabinet diagram block, identify each device graphic element, and further identify the device graphic element names of the device graphic elements "GD:1", "QD:2", "QD:3", "QD:4", "QD:5", "QD5:5", "QD:1", "QD7:6", and obtain the loop descriptions in the loop description diagram blocks (remote signal loop diagram blocks) corresponding to each device graphic element, namely "common terminal", "1DL A-phase disconnection position", "1DL A-phase closing position", "1DL B-phase disconnection position", "1DL B-phase closing position", "1DLC-phase disconnection position", "1DL C-phase closing position", "1DL three-phase disconnection position".

[0095] Step 4: Identify the device graphic element name and the sub-device name of the device graphic element, assign the loop description associated with the identified sub-device name to the sub-device element function (SubDevice Fuction) of the associated sub-device element, and generate an image recognition model file.

[0096] Identify the device graphic element name of the device graphic element. The character before the colon in the device graphic element name is the device name, and the character after the colon is the sub-device name.

[0097] In this embodiment, it is identified that the device name of the device graphic element is "GD", and the corresponding sub-device name is 1; the device name of the device graphic element is "QD", and the corresponding sub-device names are "1", "2", "3", "4", "5"; the device name of the device graphic element is "QD7", and the corresponding sub-device name is "6".

[0098] Find the associated device element and sub-device element in the substation physical logic model file according to the identified device name and sub-device name of the device graphic element, assign the loop description associated with the identified sub-device name to the sub-device element function (SubDevice Fuction) of the associated sub-device element, and generate an image recognition model file.

[0099] Step 5: Construct a physical loop information mapping association table for the intelligent archiving model file and the image recognition model file. The physical loop information mapping association table includes the loop number and the cubicle number of the cubicle element associated with the loop number in the intelligent archiving model file, the LinkA cubicle of the A-end connection point, the LinkA device of the A-end connection point, the LinkA sub-device of the A-end connection point, and the physical loop function description. The physical loop information mapping association table also includes the cubicle number of the cubicle element associated with the loop number in the image recognition model file, the LinkA cubicle of the A-end connection point, the LinkA device of the A-end connection point, the LinkA sub-device of the A-end connection point, and the physical loop function description.

[0100] In the physical loop information (Circuit) in the substation physical logic model file, search for the corresponding loop information in the order of the loop number (Circuit no), and extract the A-end connection point information, including the LinkA cubicle of the A-end connection point, the LinkA device of the A-end connection point, and the LinkA sub-device of the A-end connection point.

[0101] In the intelligent archiving model file generated in Step 2, find and locate the LinkA cubicle 1P corresponding to the loop number. In the internal connection relationship of the LinkA cubicle in the intelligent archiving model file, search for the LinkB device and the LinkB sub-device on the opposite side of the LinkA device QD and the LinkA sub-device of the A-end connection point. Read the sub-device element function of the LinkB sub-device on the opposite side, and fill the sub-device element function of the LinkB sub-device into the physical loop function description (Circuit Function) corresponding to the loop number, thus completing the filling of the physical loop function description corresponding to the loop number in the intelligent archiving model file.

[0102] Locate the LinkA Cubicle 1P, LinkA Device, and LinkASubDevice corresponding to the circuit number in the image recognition model file generated in step 4. Search for the SubDevice Function of the corresponding sub-device element under the corresponding device element under the corresponding cabinet element in the image recognition model file, and fill the found SubDevice Function into the Circuit Function corresponding to the circuit number in the physical circuit information of the image recognition model file, thus completing the filling of the physical circuit function description corresponding to the circuit number in the image recognition model file.

[0103] Based on the Circuit no in the physical circuit information, establish a mapping association table for the physical circuit information between the intelligent filing model file and the image recognition model file, as shown in Table 1. Table 1 is the mapping association table for the physical circuit information.

[0104] Table 1

[0105]

[0106] Step 6: Complete the filling of the interval voltage level and interval description for the physical circuit function descriptions corresponding to the intelligent filing model file and the image recognition model file in the mapping association table for the physical circuit information.

[0107] In the intelligent filing model file, obtain the Bay to which the LinkA Device corresponding to the circuit number belongs, read the Bay name and Bay Voltage of the Bay element, and add the interval voltage level and interval description before the physical circuit function descriptions corresponding to the corresponding circuit numbers in the intelligent filing model file and the image recognition model file, thus completing the physical circuit function descriptions (Circuit Function) corresponding to the corresponding circuit numbers in the intelligent filing model file and the image recognition model file, and obtaining different physical circuit function descriptions (Circuit Function) of the circuit number in the intelligent filing model file and the image recognition model file, as shown in Table 2. Table 2 is the mapping association table for the physical circuit information after completing the filling of the interval voltage level and interval description.

[0108] Table 2

[0109]

[0110] Step 7: Select the physical circuit function description of the most complete description elements with the same circuit number in the intelligent filing model file and the image recognition model file as the final physical circuit function description corresponding to this circuit number. Generate the physical circuit function label of the circuit number, and the physical circuit function label of the circuit number includes the circuit number, the cubicle number of the cubicle element corresponding to the circuit number, the cubicle of the A-end connection point, the device of the A-end connection point, the sub-device of the A-end connection point, and the final physical circuit function description.

[0111] According to the normative definition standard of the physical circuit function description in the power system, select the physical circuit function description (Circuit Function) with complete and correct description.

[0112] The information required to describe the physical circuit needs to include the interval voltage level, interval description, and physical circuit function description. The physical circuit function description (Circuit Function) needs to include the specific function information of the sub-device (SubDevice). Through this physical circuit function description (Circuit Function), the specific output and input of switch quantities, and the sampling output and sampling input of analog quantities are reflected.

[0113] If the physical circuit function description (Circuit Function) describes the breaker position information, the description elements of the physical circuit function description include single-phase breakers and three-phase breakers. If the physical circuit function description (CircuitFunction) describes switch quantities, the description elements of the physical circuit function description include the output information and input information of the switch quantities. If the physical circuit function description (Circuit Function) describes analog quantities, the sampling output information and sampling input information of the analog quantities, such as the protection current, protection voltage, measurement current, measurement voltage, metering current, and metering voltage under the bay, etc.

[0114] Since in the power system, there are differences between split-phase and single-phase breakers, by judging the physical circuit function description (Circuit Function) in the intelligent filing model file and the image recognition model file, select the physical circuit function description (Circuit Function) "220kV line three-phase breaker in off position" in the image recognition model file as the final physical circuit function description corresponding to the circuit number, and generate the physical circuit function label of the circuit number, as shown in Table 3. Table 3 is the physical circuit function label table.
