[0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art.

[0003] With the optimization and upgrading of the smart substation system, compared with the traditional substation where the circuit is connected by cables, the smart substation uses SCD to configure the optical cable connection, resulting in the circuit no longer being intuitively visible.

[0004] At present, the SCD file visualization system is centered on a single device. It is impossible to view all virtual circuits of the entire station or a certain interval at the same time. It is necessary to switch repeatedly between multiple devices, which is not convenient for understanding the circuit direction of the entire interval. In addition, the circuit direction varies in different regions, different voltage levels, and different wiring forms. Summary of the invention

[0036] To make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0037] It should be noted that the following detailed descriptions are all illustrative and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.

[0038] Embodiment 1

[0039] This embodiment provides a method for generating a full site view based on an SCD file.

[0040] This embodiment provides a method for generating a full-site view based on an SCD file to solve the problems of the existing visualization system being device-centric and inconvenient to view.

[0041] This embodiment provides a method for generating a full site view based on an SCD file, such as Figure 1 As shown, the following steps are included:

[0042] Step 1: SCD analysis.

[0043] The SCD file is used as the sample data source. By parsing the SCD file, based on the graph feature recognition technology and the interval basic unit, the whole station interoperability relationship network is divided into several interval protection configuration objects, that is, the sample data expressed by the graph structure.

[0044] By obtaining the voltage level, device type, circuit connection relationship, etc. of the device in the SCD file, the devices are classified according to the interval to form an interval configuration plan. Each interval configuration plan consists of devices of different voltage levels and different device types. Specifically:

[0045] Step 101: parse the SCD file to obtain the whole station device object, which includes the IED name, IED description attributes, and the included virtual terminal objects.

[0046] Specifically, parse the SCD file, obtain the device type, and get the device primary type pri_type, secondary type sec_type, and voltage level voltage_num from ied.name; if the data segment parsed from ied.name is empty, get the device primary type pri_type, secondary type sec_type, and voltage level voltage_num from the ied.desc description.

[0047] Step 102: parse the SCD file to obtain virtual circuit objects between all device objects in the entire station. The virtual circuit objects describe the connection relationship between two virtual terminal objects.

[0048] Specifically, the SCD file is parsed, and the IED device is taken as the basic unit. The switch loop with ied.name SW, the measurement and control device loop with ied.name C, and the invalid address with empty path address are excluded to obtain the device virtual terminal type. The InClass field is parsed to obtain the virtual terminal type transmission type, the prefix field is parsed to obtain the virtual terminal communication type, and LN0.desc, LN.desc, and DOI.desc are parsed in sequence until the virtual terminal description is obtained.

[0049] Step 103: Based on the parsed device object information, classify them in the order of voltage level, primary device type, and secondary device type to form a device type list. The device type list contains information about all devices in the SCD, including device name, device description, primary device type, secondary device type, voltage level, and other information.

[0050] Specifically, a list of equipment types is formed for the information of the equipment object parsed in step 101. The list of equipment types includes voltage levels, primary equipment types, secondary equipment types, etc., wherein the voltage levels include 750kV, 500kV, 220kV, 110kV, 66kV, 35kV, 10kV, etc., the primary equipment types include lines, main transformers, busbars, sections, busbars, capacitors, reactors, circuit breakers, etc., and the secondary equipment types include protection devices, merging unit devices, intelligent terminal devices, integrated intelligent devices, measurement and control devices, standby automatic switching devices, stability control devices, low-frequency load reduction devices, synchronous phasor measurement devices, etc.

[0051] Step 2: Determine the wiring type.

[0052] Step 201: Construct a list of wiring types at each voltage level.

[0053] Among them, the connection types under the 750kV voltage level are: 3 / 2 connection. The connection types under the 500kV voltage level are: 3 / 2 connection. The connection types under the 220kV voltage level are: double mother connection, double mother single tap connection, double mother double tap connection. The connection types under the 110kV voltage level are: double mother connection, double mother single tap connection, double mother double tap connection, single mother connection, single mother segmented connection, single mother double tap connection, inner bridge connection, expanded inner bridge connection, and outer bridge connection.

[0054] Step 202: Obtain each voltage level in the station from the equipment type list, and determine the wiring form under the voltage level according to the voltage level and other judgment criteria.

[0055] Among them, under the 750kV voltage level, the 3 / 2 connection determines the string and circuit breaker position by judging the third and fourth digits of the digital number in the IED name of the circuit breaker protection. For example, PB7510, by judging the third digit 1 and the fourth digit 0, it can be obtained that the circuit breaker protection is the side circuit breaker of the first string.

[0056] Among them, at the 500kV voltage level, the 3 / 2 connection determines the string and the circuit breaker position by judging the third and fourth digits of the digital number in the IED name of the circuit breaker protection. For example, for PB5011, by judging the third digit 1 and the fourth digit 1, it can be obtained that the circuit breaker protection is the side circuit breaker of the first string;

[0057] Among them, under the 220kV voltage level, the specific wiring form is determined by judging the number of bus tie protection devices and the number of segment protection devices. If the number of bus tie protection devices is 2 and the number of segment protection devices is 2, it indicates that the wiring type is double bus and double tap wiring; if the number of bus tie protection devices is 2 and the number of segment protection devices is 1, it indicates that the wiring type is double bus and single tap wiring; if the number of bus tie protection devices is 1 and the number of segment protection devices is 0, it indicates that the wiring type is double bus wiring.

[0058] Among them, under the 110kV voltage level, the specific wiring form is determined by judging the number of bus tie protection devices and the number of segment protection devices. If the number of bus tie protection devices is 2 and the number of segment protection devices is 2, it indicates that the wiring type is double bus double tap wiring; if the number of bus tie protection devices is 2 and the number of segment protection devices is 1, it indicates that the wiring type is double bus single tap wiring; if the number of bus tie protection devices is 1 and the number of segment protection devices is 0, it indicates that the wiring type is double bus wiring; if the number of bus tie protection devices is 0 and the number of segment protection devices is 1, it indicates that the wiring type is single bus single tap wiring; if the number of bus tie protection devices is 0 and the number of segment protection devices is 2, it indicates that the wiring type of the substation at this voltage level is single bus double tap wiring;

[0059] In particular, in the double-bus single-tap wiring form, if there is a virtual circuit between a bus merging unit and two bus merging units, the bus corresponding to this bus merging unit is a long bus, and the remaining two busbars are segment buses.

[0060] Step 203: Based on the wiring type, the correspondence between the line and the bus is determined according to the virtual circuit connection between the line intelligent terminal or the line intelligent integration and the bus protection; the correspondence between the main transformer intelligent terminal or the main transformer intelligent integration and the bus protection is determined, and the correspondence between the main transformer and the bus is determined.

[0061] For example, after knowing that the wiring form of the 220kV side of a 220kV substation is a double-mother and double-branch wiring type, the connection status of the 220kV line 1 and the 220kV bus is determined by analyzing the virtual circuit between the 220kV line 1 intelligent terminal A set and the 220kV bus protection.

[0062] Step 204: If step 203 cannot determine, determine the connection status of the SV virtual circuit between the line merging unit and the bus merging unit or the name of the virtual terminal corresponding to the virtual circuit to determine which bus the line is connected to; determine the connection status of the SV (Sampled Value) virtual circuit between the main transformer merging unit and the bus merging unit or the name of the virtual terminal corresponding to the virtual circuit to determine which bus the main transformer is connected to.

[0063] Specifically, at the 220kV voltage level, if there is no virtual circuit between the line intelligent terminal or the line intelligent integration and the bus protection, the virtual terminal names corresponding to the virtual circuits of the line merging unit and the bus merging unit are determined to determine the corresponding relationship between the line and the bus; the virtual terminal names corresponding to the virtual circuits between the main transformer merging unit and the bus merging unit are determined to determine the corresponding relationship between the main transformer and the bus. At the 110kV level, if there is no virtual circuit between the line intelligent terminal or the line intelligent integration and the bus protection, the virtual terminal names corresponding to the virtual circuits of the line merging unit and the bus merging unit are determined to determine the corresponding relationship between the line and the bus; the virtual terminal names corresponding to the virtual circuits between the main transformer merging unit and the bus merging unit are determined to determine the corresponding relationship between the main transformer and the bus.

[0064] Step 205: If the virtual terminal name is not standardized or lacks a corresponding virtual circuit, the names of the line intelligent terminals or the line intelligent integration are arranged in ascending order, and the names of the main transformer intelligent terminals or the main transformer intelligent integration are arranged in ascending order.

[0065] Step 204 determines which bus the line is connected to by the virtual terminals corresponding to the virtual circuits between the line merging unit and the bus merging unit. If the virtual terminals are not named in a standardized manner, they are sorted in ascending order of the names of the line intelligent terminals or the line intelligent integration.

[0066] Step 3: Generate SCD full site view.

[0067] Step 301, main interface design: main station view module, including high voltage module, medium voltage module, low voltage module, main transformer module, and common equipment module. The high voltage module includes high voltage line module, high voltage bus module, high voltage bus coupling module, and high voltage segmentation module; the medium voltage module includes medium voltage line module, medium voltage bus module, and medium voltage bus coupling (segmentation) module; the low voltage module includes low voltage line module, low voltage bus module, and low voltage bus coupling (segmentation) module; the main transformer module includes main transformer high voltage side module, main transformer medium voltage side module, main transformer low voltage side module, and main transformer body module.

[0068] Step 302: Determine the number of main transformers according to the number of main transformer intelligent terminals or main transformer integrated intelligent devices, and determine the main interface format according to the number of main transformers:

[0069] (1) If the main transformer is a two-circuit transformer (the transformer corresponds to two voltage levels, for example: 110kV to 10kV; 220kV to 10kV), that is, there are only two voltage levels, high and low voltage sides, then the high voltage level area is placed above the main transformer intelligent terminal or the main transformer combined intelligent integration, and the low voltage level area is placed below the main transformer intelligent terminal or the main transformer combined intelligent integration;

[0070] (2) If the main transformer is a three-circuit transformer, that is, there are three voltage levels: high, medium, and low voltage sides, then the high voltage level area is placed above the main transformer intelligent terminal or the main transformer intelligent integration, the medium voltage level area is placed to the right of the main transformer intelligent terminal or the main transformer intelligent integration, and the low voltage level area is placed below the main transformer intelligent terminal or the main transformer intelligent integration;

[0071] (3) Station-level equipment is placed in the upper right corner, to the right of the high voltage level area, and above the medium voltage level.

[0072] Step 303: Determine the whole station view according to the wiring forms of each voltage level and the corresponding relationship between the line, main transformer, section, bus coupler and bus.

[0073] Taking a 220kV station as an example, its high-voltage part is 220kV, and the wiring form is double mother and double branch; the medium-voltage part is 110kV, and the wiring form is double mother and double branch; the low-voltage part is 10kV; and the number of main transformers is 2.

[0074] like Figure 2 The following is a full view of a 220kV substation. Under each voltage level, it is divided into line area, bus area, bus coupling area, and bus sub-area. Because the transformer contains multiple voltage levels, the transformer is displayed as a separate area, which is divided into high voltage side, medium voltage side, and low voltage side. Among them, the bus area will have different display forms depending on the connection type.

[0075] This embodiment visualizes the SCD file in the form of a primary equipment main wiring diagram, so that it is more in line with the working habits of professionals and can quickly locate the required position.
