[0040] Example 1

[0041] See also Figure 1 , shows a flow chart of a method for constructing a substation physical configuration description file provided by a first embodiment of the present invention. This method can be executed by a device for constructing a substation physical configuration description file. The device for constructing a substation physical configuration description file can be implemented in the form of hardware and / or software. The device for constructing a substation physical configuration description file can be configured in an electronic device. Figure 1 As shown, the method includes:

[0042] Step 101: Divide the substation into M typical bays according to the substation construction drawing data.

[0043] In practical applications, the substation designer provides digital construction drawings of the substation. Based on the content of the substation construction drawing data (such as information about the panel cabinet), the substation is divided into M typical intervals (M is a positive integer).

[0044] Each typical interval includes N identical intervals (N is a positive integer), and each identical interval includes K screen cabinets (K is a positive integer).

[0045] In the specific implementation, the main wiring diagram, bay division diagram and electrical secondary volume drawings are read from the construction drawing data of the substation; the entire station is divided into M typical bays according to the main wiring diagram, bay division diagram and electrical secondary volume drawings; N identical bays are divided in each typical bay, so that each identical bay includes K-sided panel cabinets.

[0046] The typical interval includes at least one of the following:

[0047] Main transformer bay, line bay, busbar bay, bus coupling bay, bus branch bay, circuit breaker bay and common bay.

[0048] The main difference between the same bays is the bay name. The same bay contains the same number of panel cabinets, and the equipment configuration information in the panel cabinets is the same.

[0049] The fiber jumper configuration information and physical connection information in the same interval cabinets are the same;

[0050] The physical cable connection information between cabinets in the same bay is the same;

[0051] The physical cable connection information between the inter-bay cabinets of the same interval is similar, that is, in the physical cable connection information between the inter-bay cabinets of the same interval, the port path information within the cabinets of the same interval is the same, and the port paths within the cabinets of non-compartmental intervals are similar.

[0052] Taking a 220kV substation as an example, according to the main connection diagram of the construction drawing data, the 220kV part adopts double busbar single-section connection, and the 110kV part adopts single busbar two-section three-section busbar connection. In this phase, there are 4 220kV outgoing lines and 6 110kV outgoing lines. In this phase, 2 three-winding main transformers are configured according to the final scale.

[0053] According to the interval division diagram in the construction drawing data, the typical intervals of the entire station include 220kV busbar interval, 220kV line interval, 220kV bus tie interval, 220kV sectional interval, 110kV busbar interval, 110kV line interval, 110kV sectional interval and main transformer interval.

[0054] Among them, the typical interval of 220kV line includes 4 identical 220kV line intervals; the typical interval of 220kV section includes 2 identical 220kV section intervals; the typical interval of main transformer includes 2 identical main transformer intervals; the typical interval of 110kV line includes 6 identical 110kV line intervals.

[0055] Each 220kV line bay includes a 220kV line intelligent control cabinet, which contains 220kV line protection A set of devices, 220kV line merging unit A set of devices, 220kV line intelligent terminal A set of devices, 220kV line protection B set of devices, 220kV line merging unit B set of devices, 220kV line intelligent terminal B set of devices, 220kV line measurement and control devices, 220kV line A network process layer switch, 220kV line B network process layer switch and 220kV line electric energy meter and other equipment.

[0056] Step 102: Model the small room and panel cabinet in the substation to obtain the small room model information and the panel cabinet model information.

[0057] In actual applications, the substation designer provides the digital layout diagram of the relay room and switch area of ​​the substation. Based on the layout diagram of the relay room and switch area, a panel cabinet information table is prepared, and the small rooms and panel cabinets in the substation are modeled to obtain the small room model information and panel cabinet model information.

[0058] For example, Figure 2 The panel cabinet information shown indicates that the substation is designed as an indoor substation. The entire station consists of 6 small rooms, including the main control room, relay room, GIS room, secondary equipment room, 220kV GIS room, 110kV GIS room, main transformer room and 10kV high-voltage distribution room. A corresponding panel layout diagram is provided for each small room.

[0059] In a specific implementation, a panel information table is constructed for the substation; the header of the panel information table includes information such as the room name, panel number, and panel description.

[0060] According to the principle of matching the cell name with the cell (region) element attribute definition, the cell name is converted into cell (region) model information that conforms to the substation physical configuration description file.

[0061] According to the principle of matching the panel cabinet number, panel cabinet description and panel cabinet (Cubicle) element attribute definition, the panel cabinet information in the panel cabinet information table is converted into panel cabinet (Cubicle) model information that conforms to the substation physical configuration description file.

[0062] Among them, the panel cabinets include indoor secondary panel cabinets for relays, indoor switch cabinets for high-voltage distribution, intelligent control cabinets in switch yards, and intelligent control cabinets.

[0063] In addition, the cabinet number is unique within the table.

[0064] Step 103: Import the optical cable inventory information of the substation into a preset optical cable inventory template to obtain physical cable model information.

[0065] In actual applications, the substation designer provides the digitized optical cable inventory information of the substation, imports the optical cable inventory information of the substation into a preset optical cable inventory template for modeling, and obtains the physical cable model information.

[0066] The optical cable inventory shall record at least one of the following physical cable information:

[0067] Fiber optic cables, pigtail cables, patch cables, and twisted pair cables.

[0068] In one embodiment of the present invention, step 103 may include the following steps:

[0069] Step 1031: Standardize the header of the optical cable inventory information of the substation according to the preset optical cable inventory form template.

[0070] In this embodiment, if Figure 3 As shown in the figure, the header of the optical cable inventory information includes the cable number, description, length, number of cores, starting point, end point, and type.

[0071] The header of the substation's optical cable inventory information is standardized according to the preset optical cable inventory form template, so that the header of the optical cable inventory information is converted into a unified format. At this time, the start and end points of the header fields in the optical cable inventory information are the cabinet names.

[0072] In a specific implementation, when the starting point and the end point in the optical cable inventory table are described as a screen cabinet, the screen cabinet information table is queried.

[0073] In the cabinet information table, convert the cabinet description into the cabinet name so that the starting point and end point in the header of the optical cable inventory are both the cabinet names.

[0074] When the starting and ending points in the optical cable inventory table include the cabinet description and cabinet name, extract the cabinet name as the starting and ending points in the header of the optical cable inventory.

[0075] Step 1032: If the normalization process is completed, the physical cable information in the optical cable inventory is converted into physical cable model information that complies with the substation physical configuration description file according to the principle of matching the header of the optical cable inventory information with the physical cable element attribute definition.

[0076] In this embodiment, if the normalization processing is completed, the physical cable information in the optical cable inventory can be converted into physical cable model information that conforms to the substation physical configuration description file according to the principle of matching the header of the optical cable inventory information with the physical cable (Cable) element attribute definition.

[0077] For example, Figure 4 As shown in the figure, after importing the optical cable list, some optical cable modeling information of the 220kV Line 1 and Line 2 intelligent control cabinets is obtained.

[0078] In this example, the starting point R003.C1 and the end point R003.C5 of the optical cable 1E-101A-GL model match the 220kV line-1 intelligent control cabinet and the 220kV IM bus intelligent control cabinet in the station-wide cabinet information table, respectively.

[0079] In the specific implementation, the cable number, description, length, number of cores, starting point, end point and type in the header of the optical cable inventory are matched with the cable number (name), cable description (desc), length (length), number of cores (coreNum), connected A cabinet path (cubicleA), connected B cabinet path (cubicleB) and type (type) of the physical cable (Cable) element attributes in sequence.

[0080] When the match is successful, the cable number, description, length, number of cores, start point, end point or type in the header of the optical cable inventory is converted into physical cable model information that conforms to the substation physical configuration description file.

[0081] When the match fails, the cable number, description, length, number of cores, start point, end point or type in the header of the optical cable inventory is written as a null value into the physical cable model information that conforms to the substation physical configuration description file.

[0082] Step 104: Extract the intelligent electronic device information of the substation from the substation system configuration description file of the substation.

[0083] In this embodiment, the intelligent electronic device (IED) information of the substation is extracted from a substation system configuration description (SCD) file of the substation.

[0084] Among them, the intelligent electronic device information includes the intelligent electronic device name and the intelligent electronic device description.

[0085] For example, when importing an SCD file, the names of the IED devices belonging to a 220kV line bay are PL2201A, ML2201A, IL2201A, PL2201B, ML2201B, IL2201B, CL2201, SW221101, and SW221102 respectively; the descriptions of the IED devices are 220kV line protection device A, 220kV line merging unit device A, 220kV line intelligent terminal device A, 220kV line protection device B, 220kV line merging unit device B, 220kV line intelligent terminal device B, 220kV line measurement and control device, 220kV line A network process layer switch, and 220kV line B network process layer switch.

[0086] Step 105 : For each typical interval, upon receiving the physical loop model information of the first identical interval in the typical interval, expand the physical loop model information of other identical intervals based on the physical loop model information of the first identical interval.

[0087] In this embodiment, the physical loop model information of the first identical interval (source interval) in the i-th typical interval can be completed, and the physical loop model information of other identical intervals of the typical interval can be expanded by interval replication. After verification and modification, the physical loop model information of all identical intervals of the i-th typical interval can be completed.

[0088] Furthermore, the interval replication specifically includes replication of information about the screen cabinets and devices in the cabinets to which the source interval belongs and replication of cable connection information between the screen cabinets to which the source interval belongs.

[0089] For example, when the design institute publishes the design drawings, the 220kV line bays use the same design drawings, and therefore, the 220kV line bays have the same optical fiber loops.

[0090] In this embodiment, the first bay of the 220 kV line is used as the source bay of the typical bay of the 220 kV line, and the second, third, and fourth bays of the 220 kV line are used as the target bays.

[0091] Use the relevant SPCD model editing tool to manually create the panel cabinet and related optical fiber loop model belonging to the first bay of the 220kV line.

[0092] According to the design drawings, the 1E-101A-GL optical cable is a 4-core cable, with one core in use and three cores in reserve. Core 1 is used to cascade the line bay merging unit A in the 220kV Line 1 intelligent control cabinet and the busbar merging unit A suite SV in the 220kV IM busbar intelligent control cabinet.

[0093] The model information corresponding to the optical cable 1E-101A-GL is as follows:

[0094] <Cable name="1E-101A-GL" desc="" type="GL"cubicleA="R003.C1"cubicleB="R003.C5" length="18"coreNum="4">

[0095] <Core no="1"reserve="false"portA="13n.1.K-Tx"portB="1-13n.1.F-Rx" / >

[0096] <Core no="2"reserve="ture"portA=""portB="" / >

[0097] <Core no="3"reserve="ture"portA=""portB="" / >

[0098] <Core no="4"reserve="ture"portA=""portB="" / >

[0099]

[0100] In this example, portA="13n.1.K-Tx" is the starting port path, indicating the Kth optical port on board 1 of busbar merging unit A (13n represents the equipment number of busbar merging unit A) in a 220kV IM bus intelligent control cabinet. portB="1-13n.1.F-Rx" is the ending port path, indicating the Fth optical port on board 1 of bay merging unit A (1-13n represents the equipment number of bay merging unit A) in a 220kV line-1 intelligent control cabinet. The elements of portA and portB represent the optical cable connection relationship.

[0101] Since the optical cable 2E-101A-GL belonging to the second bay of the 220kV line has been created by importing the optical cable inventory, the content of the optical cable core (core) element is empty. The model information corresponding to the optical cable 2E-101A-GL is as follows:

[0102] <Cable name="2E-101A-GL" desc="" type="GL"cubicleA="R003.C2"cubicleB="R003.C5" length="29"coreNum="4">

[0103] <Core no="1"reserve="false"portA=""portB="" / >

[0104] <Core no="2"reserve="false"portA=""portB="" / >

[0105] <Core no="3"reserve="false"portA=""portB="" / >

[0106] <Core no="4"reserve="false"portA=""portB="" / >

[0107]

[0108] In one case, the replication of information about the source bay's panel cabinets and the equipment within them includes:

[0109] The device (Unit) element information in the panel cabinet in the first physical circuit model information of the same interval is copied to the device element information in the panel cabinet (target panel cabinet) in the physical circuit model information of other same intervals.

[0110] The unit element information in the panel cabinet includes intelligent electronic devices (IED), optical fiber distribution frames (ODF), switches (SWITCH), and other devices (OTHER).

[0111] The attribute information of the device (Unit) element in the panel cabinet in the first physical circuit model information of the same interval is copied to the attribute information of the device element in the panel cabinet in other physical circuit model information of the same interval.

[0112] Among them, the attribute information in the device (Unit) element in the panel cabinet includes board (Board), port (Port), etc.

[0113] The intcore information of the first physical loop model information of the same interval is copied to the intcore information of the other physical loop model information of the same interval.

[0114] Furthermore, specific information is added to the IED name (iedName) information in the target panel cabinet.

[0115] When the same cabinet contains devices with different intervals, the copy cabinet function cannot be used.

[0116] For example, the source panel cabinet 220kV line one intelligent control cabinet is copied to the target panel cabinet 220kV line two intelligent control cabinet.

[0117] Select the 220kV Line 1 Intelligent Control Cabinet as the source cabinet, copy the cabinet, expand a 220kV Line 1 Intelligent Control Cabinet (copy) cabinet, manually change the name to 220kV Line 2 Intelligent Control Cabinet cabinet, and use the expanded cabinet as the target cabinet.

[0118] The name and description of the IED device in the target panel cabinet are added with the specific suffix "copy". The other information of the target panel cabinet model is exactly the same as that of the source panel cabinet model.

[0119] Since the SCD file has been imported, the IED device information of the entire station has been extracted. By searching for the names of the IED devices in the second bay of the 220kV line, the names and descriptions of the IED devices with "copy" in the cabinet are replaced, and finally the cabinets with the same bay can be replicated and expanded.

[0120] In another case, the copying of cable connection information between the panel cabinets in the source bay includes:

[0121] The cable information in the first physical loop model information of the same interval and the cable information in other physical loop model information of the same interval are preprocessed.

[0122] Among them, the preprocessing includes listing all cable information centered on the screen cabinets belonging to the source interval and the target interval, arranging the cable information in a specific order, and deduplicating the cable information centered on the screen cabinet.

[0123] For example, a 220kV line interval includes one line intelligent control cabinet. There is no inter-cabinet optical fiber between multiple screen cabinets in the line interval. There is no need to remove duplicate optical cables from the inter-cabinet optical fibers in the interval. To facilitate manual inspection and one-to-one copying of optical cable connection information, the optical cable numbers in the source interval and the target interval are sorted in alphabetical order.

[0124] If the preprocessing is completed, the cable information in the first physical loop model information of the same interval is copied to the cable information in the other physical loop model information of the same interval.

[0125] Furthermore, if the A cabinet (cubicleA) and the B cabinet (cubicleB) to which the cable is connected in the physical loop model information of the first same interval are both in the first same interval, the optical cable core (core) element information in the physical loop model information of the first same interval is copied to the optical cable core (core) element information in the physical loop model information of other same intervals.

[0126] The optical cable core element information includes the core serial number, spare core identifier, the path of the fiber core connected to port A (portA), and the path of the fiber core connected to port B (portB).

[0127] If the A cabinet (cubicleA) or B cabinet (cubicleB) to which the cable is connected in the physical loop model information of the first identical interval is not in the first identical interval, the attributes of the path (portA or portB) of the cable fiber core corresponding to the A cabinet (cubicleA) or B cabinet (cubicleB) connected to the A port or B port in the physical loop model information of the first identical interval are copied to the optical cable core element information in the physical loop model information of other identical intervals.

[0128] For example, the specific implementation steps for copying the connection information of the optical cable 1E-101A-GL belonging to the first bay of the 220kV line to the optical cable 2E-101A-GL belonging to the second bay of the 220kV line are as follows:

[0129] (1) PortA port path replication

[0130] Because the 220kV IM busbar intelligent control cabinet is a busbar bay, not a source bay panel in a line bay, the port path element portA content for the first core of the optical cable 2E-101A-GL in the second bay of the 220kV line is different from the port path element portA content for the first core of the optical cable 1E-101A-GL in the first bay of the 220kV line. Therefore, specific information must be added, such as the "Copy" suffix, portA = "13n.1.K-Tx Copy".

[0131] For port paths with duplicate information, locate and mark the color to remind users to check the drawings and make corrections based on the actual physical connection information. After correction, portA = "13n.1.L-Tx".

[0132] (2) Port B port path replication

[0133] Because the 220kV Line 1 intelligent control cabinet is the source bay panel cabinet of the line bay, the port path element content of the first core of the optical cable 2E-101A-GL in the 220kV Line 2 bay is the same as the port path element content of the first core of the optical cable 1E-101A-GL in the 220kV Line 1 bay, portB = "1-13n.1.F-Rx".

[0134] After copying, searching, and modifying the optical cable connection information, the model information corresponding to the optical cable 2E-101A-GL is as follows:

[0135] <Cable name="2E-101A-GL" desc="" type="GL"cubicleA="R003.C2"cubicleB="R003.C5" length="29"coreNum="4">

[0136] <Core no="1"reserve="false"portA="13n.1.L-Tx"portB="1-13n.1.F-Rx" / >

[0137] <Core no="2"reserve="false"portA=""portB="" / >

[0138] <Core no="3"reserve="false"portA=""portB="" / >

[0139] <Core no="4"reserve="false"portA=""portB="" / >

[0140]

[0141] The other optical cables belonging to the second bay of the 220kV line are created using the same method.

[0142] Step 106: Construct a substation physical configuration description file of the substation based on the small room model information, the panel cabinet model information, the intelligent electronic device information and the physical loop model information.

[0143] In this embodiment, the physical loop model configuration and verification modification of all typical intervals of the substation are completed, and the substation physical configuration description file of the substation is constructed based on the small room model information, panel cabinet model information, intelligent electronic device information and physical loop model information of all typical intervals.

[0144] In this embodiment, the substation is divided into M typical intervals based on the construction drawing data of the substation; each typical interval includes N identical intervals, and each identical interval includes K-sided panels; the small rooms and panels in the substation are modeled to obtain small room model information and panel model information; the optical cable inventory information of the substation is imported into a preset optical cable inventory template to obtain physical cable model information; the intelligent electronic device information of the substation is extracted from the substation system configuration description file of the substation; for each typical interval, when the physical loop model information of the first identical interval in the typical interval is received, the physical loop model information of other identical intervals is expanded based on the physical loop model information of the first identical interval; the substation physical configuration description file of the substation is constructed based on the small room model information, panel model information, intelligent electronic device information and physical loop model information.

[0145] First, this embodiment integrates multiple source data for modeling, which helps to improve the efficiency and accuracy of SPCD modeling; among them, there is no need to repeatedly enter IED information during IED modeling, avoiding problems such as IED information errors, omissions and inconsistencies that may arise in IED modeling; the modeling of a large number of optical cables throughout the station does not require manual creation one by one, and the optical cable information in the optical cable inventory can be input with one click, reducing the time for optical cable modeling.

[0146] Secondly, this embodiment utilizes typical intervals and identical interval features and uses a copy interval method for rapid modeling. In the SPCD modeling process, the concept of intervals is applied, the features of identical intervals are utilized, and a copy interval method is adopted to rapidly complete batch modeling, thereby reducing the workload of repeated modeling and improving modeling efficiency.

[0147] Furthermore, this embodiment combines the current implementation status of physical circuit model configuration during substation design, construction, commissioning and operation and maintenance, proposes a more suitable SPCD configuration implementation process, develops SPCD rapid modeling based on this process, and improves SPCD modeling efficiency.
