Description

Technical Field

[0001] The present invention belongs to the technical field of virtual circuit hidden danger detection, and in particular relates to a method, system, equipment and medium for constructing a standard virtual terminal circuit connection rule library. Background Art

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

[0003] The SCD (Substation Configuration Description) file is the basic data source for the engineering design, commissioning, and operation and maintenance of smart substations. It is also a key file for realizing the engineering configuration, joint commissioning, and operation and maintenance of substation automation systems. Therefore, the correctness of the SCD file and whether there are changes directly affect the correctness of the secondary equipment functions. During the commissioning, acceptance, maintenance, overhaul, and renovation and expansion of smart substations, the version of the SCD file will change frequently. There are many virtual circuits in the SCD file. During the version change process, it is impossible to fully describe the details of the changes in the virtual circuits. The configuration of the virtual circuits sometimes has problems such as missed connections, incorrect phase configuration, location, tripping, locking, and other important circuits missing. These errors may seriously affect the safe operation of the entire substation.

[0004] The standard virtual terminal circuit connection rule base provides technical support for the hidden danger inspection of the virtual circuit of the SCD file. By checking the wrong circuit, missing circuit, and redundant circuit, it can ensure the correctness of the virtual circuit of the SCD file, improve the control of the SCD file of the substation, and ensure the normal operation of the substation equipment. Since the virtual circuits between secondary devices of different voltage levels, wiring methods, interval types, and equipment types are different, the standard virtual terminal circuit connection rule base needs to create standard virtual circuits of different voltage levels, wiring methods, interval types, and equipment types according to the SCD files put into operation by the substation; and the existing methods usually use manual creation to create standard virtual circuits, which have the following problems:

[0005] On the one hand, there are usually a large number of IED devices (Intelligent Electronic Devices) under the substation SCD. The more IED devices there are, the more standard virtual terminal loop connections will increase exponentially, and the manual creation method is inefficient; secondly, the standard virtual terminal loop connection is usually completed independently by a single designer, and it is not easy to split it into multiple people to complete independently. Even if it is completed by multiple people, there are problems such as scattered versions and inability to achieve fast and instant synchronization and merging, which results in a large workload and low configuration efficiency for the SCD configuration. This problem is more prominent when time is tight; thirdly, the correctness of the standard virtual terminal loop directly depends on the technical level of the configuration personnel, and it can only be formed after a large number of modifications and improvements, which is time-consuming and has low accuracy.

[0044] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0045] It should be noted that the following detailed descriptions are exemplary and are 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.

[0046] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit exemplary embodiments according to the present invention. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprising" and / or "including" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0047] In the absence of conflict, the embodiments of the present invention and the features of the embodiments may be combined with each other.

[0048] Terminology explanation:

[0049] SCD: Substation Configuration Description, substation configuration description file;

[0050] ICD: IED Capability Description, IED capability description file;

[0051] IED: Intelligent Electronic Device, intelligent electronic device;

[0052] Virtual terminal: A general term for the GOOSE input signal connection point, GOOSE output signal connection point, SV input signal connection point, and SV output signal connection point of an IED device, used to identify the secondary circuit signals of the process layer, bay layer, and the connections between them;

[0053] Manufacturer virtual terminal: refers to the virtual terminal name used in the ICD file provided by the device manufacturer;

[0054] Standard virtual terminal: refers to the virtual terminal naming specified in the IEC 61850 specification.

[0055] In order to solve the problems existing in the prior art, such as Figure 1As shown, this embodiment provides a method for constructing a standard virtual terminal loop connection rule base, including:

[0056] Step 1: Based on the parsing result of the SCD file, obtain the intelligent electronic device attribute information; based on the intelligent electronic device attribute information, extract the first attribute information set and the second attribute information set respectively;

[0057] Among them, the parsing of the SCD file is specifically as follows: for the imported SCD file, the high-voltage side voltage level, high-voltage side wiring method, medium-voltage side voltage level, medium-voltage side wiring method, low-voltage side voltage level, and low-voltage side wiring method of the SCD file are automatically parsed, and manual modification and confirmation are supported. After confirmation, the name, description, control block, and input and output circuit connection relationship of the intelligent electronic device (i.e., IED) in the SCD file are traversed and read, and the device type, interval type, voltage level, wiring method, manufacturer, model, version, and virtual terminal set of the IED in the SCD file are parsed, and manual modification and confirmation are supported. After confirmation, the next step is executed.

[0058] It should be noted here that the automatic parsing of the SCD file is a routine operation for those skilled in the art, so the specific process of the automatic parsing will not be described in detail here.

[0059] like Figure 2 As shown, the IED and virtual terminal circuits obtained by parsing the SCD file are displayed.

[0060] Step 2: Based on the first attribute information set, for the intelligent electronic devices with the same attribute information, a unique manufacturer device capability description file is extracted, and a manufacturer virtual terminal is constructed;

[0061] Among them, the first attribute information set includes the device type, manufacturer, model and version of the intelligent electronic device; the union of the virtual terminal sets corresponding to the intelligent electronic devices with the same attribute information is used as the manufacturer virtual terminal.

[0062] Specifically, the step 2 specifically performs the following processing:

[0063] According to the four attributes of IED device type, manufacturer, model, and version in the SCD file, the manufacturer intelligent electronic device capability description file (i.e., manufacturer ICD) is extracted. IEDs with the same device type, manufacturer, model, and version are extracted as one manufacturer ICD, and the union of these IED virtual terminal sets is extracted as the virtual terminal set of the manufacturer ICD. The attributes of the virtual terminal (i.e., manufacturer virtual terminal) of the manufacturer ICD include: virtual terminal type (SV send / SV receive / GOOSE send / GOOSE receive), virtual terminal description, and virtual terminal internal short address.

[0064] like Figure 3 and Figure 4 As shown, the extracted manufacturer ICD and manufacturer virtual terminal result schematic diagram are displayed.

[0065] Step 3: Based on the second attribute information set, for the intelligent electronic devices with the same attribute information, a unique standard intelligent electronic device is extracted, and a standard virtual terminal is constructed;

[0066] The second attribute information set includes the device type, interval type, voltage level and wiring mode of the intelligent electronic device, and a standard virtual terminal is constructed based on the virtual terminal set corresponding to the standard intelligent electronic device;

[0067] Specifically, step 3 specifically performs the following processing:

[0068] The standard IED is uniquely determined according to the four attributes of the IED device type, bay type, voltage level, and wiring method in the SCD file. The IEDs with the same device type, bay type, voltage level, and wiring method are extracted as a standard IED. In the scheme described in this embodiment, it is supported to select one of the IEDs and use the virtual terminal set of the IED as the virtual terminal set of the standard IED. The attributes of the virtual terminal of the standard IED (i.e., the standard virtual terminal) include: virtual terminal type (SV (Sampled Value: sampled value) send / SV receive / GOOSE (Generic Object Oriented Substation Events: Generic Object Oriented Substation Events) send / GOOSE receive), virtual terminal description.

[0069] It should be noted here that the traditional method usually extracts a large number of attributes (for example: set type, 3 / 2 wiring, whether failure protection is enabled at the 110kV voltage level, whether a merging unit is used, main transformer protection type and whether it is equipped with a main merging unit, etc.) to determine the standard IED. Different from the traditional method, the scheme described in this embodiment only selects four attributes: equipment type, bay type, voltage level and wiring method. This method can effectively reduce the number of standard IEDs, thereby effectively reducing the workload of subsequent creation of standard virtual terminal loop connections and improving the construction efficiency of standard virtual terminals.

[0070] In a specific implementation, an IED may be randomly selected, and the virtual terminal set of the IED may be used as the virtual terminal set of the standard IED.

[0071] like Figure 5 and Figure 6 As shown, the extracted standard IED and standard virtual terminal result schematic diagram are displayed.

[0072] Step 4: Based on the correspondence between the manufacturer's device capability description file and the standard intelligent electronic device, a mapping relationship between the manufacturer's virtual terminal and the standard virtual terminal is constructed;

[0073] Among them, according to the manufacturer ICD and standard IED extracted from the IED in the SCD file, the corresponding relationship between the manufacturer ICD and the standard IED is automatically established, and the mapping relationship between the manufacturer virtual terminal and the standard virtual terminal is automatically established according to the manufacturer virtual terminal description and the standard virtual terminal description, supporting manual modification and maintenance.

[0074] In a specific implementation, the manufacturer's equipment capability description file and the standard intelligent electronic device are obtained through the intelligent electronic device attribute information parsed from the SCD file, and the correspondence between the manufacturer's equipment capability description file and the standard intelligent electronic device is automatically obtained when the manufacturer's equipment capability description file and the standard intelligent electronic device are extracted.

[0075] The establishment of the corresponding relationship is illustrated by the following example:

[0076] For example, the manufacturer ICD extracted from IED (PL2201A-220kV first line protection device) is: protection device-XX company name-CSC-103A-DA-G-V2.00, and the standard IED extracted is: protection device-line-220kV-dual mother, and then, the manufacturer ICD (protection device-XX company name-CSC-103A-DA-G-V2.00) and the standard IED (protection device-line-220kV-dual mother) automatically create a corresponding relationship. That is, both the manufacturer ICD and the standard IED can be extracted from one IED, and the manufacturer ICD extracted by the IED and the standard IED will automatically create a corresponding relationship.

[0077] In the specific implementation, the principle of establishing the mapping relationship is as follows:

[0078] All virtual terminals of IED in SCD file are extracted as manufacturer virtual terminals. Virtual terminals with loops in IED are standard virtual terminals. A virtual terminal with loops can be extracted as either a manufacturer virtual terminal or a standard virtual terminal. The mapping relationship between the extracted manufacturer virtual terminal and the standard virtual terminal is automatically created.

[0079] like Figure 7 and Figure 8 The figure shows the schematic diagram of the automatic mapping result between the manufacturer's virtual terminals and the standard virtual terminals;

[0080] Step 5: Based on the loop connection of the virtual terminal of the intelligent electronic device in the analysis result, combined with the manufacturer's equipment capability description file and the manufacturer's virtual terminal, the standard intelligent electronic device and the standard virtual terminal, and the mapping relationship, the loop connection of the standard virtual terminal between the standard intelligent electronic devices is obtained to realize the construction of the rule base.

[0081] In the specific implementation, the obtained standard virtual terminal circuit needs to be manually modified and confirmed, such as Fig. 9 As shown in the figure, the standard virtual terminal loop obtained by automatic mapping is displayed. Fig.10 As shown, the standard virtual terminal circuit obtained after manual modification and confirmation is displayed.

[0082] It should be noted here that the reason why the standard virtual terminal circuit needs to be manually modified and confirmed is:

[0083] The naming of standard virtual terminals is the IED virtual terminal name extracted from the SCD file. The naming may not comply with the IEC61850 specification, so it is necessary to manually modify and maintain the standard virtual terminal name;

[0084] The SCD file is not necessarily standardized, that is, the virtual terminal circuit in the SCD file is not necessarily correct, so the extracted virtual terminal circuit is not necessarily the correct standard virtual terminal circuit. Therefore, manual confirmation is required to delete the wrong circuit and add the missing circuit.

[0085] In a specific implementation, the analysis result of the SCD file, the determination of the standard intelligent electronic device, and the mapping relationship between the manufacturer's virtual terminals and the standard virtual terminals are all provided with a manual modification and maintenance mechanism.

[0086] It should be noted here that the reason for adopting the manual modification and maintenance mechanism is that there is no guarantee that the SCD file is standardized. For non-standard SCD files, it is impossible to guarantee that the correct information can be extracted. Therefore, it is necessary to support manual modification and maintenance, which mainly maintains the following information:

[0087] The device type, voltage level, and interval type of the standard IED are parsed based on the name and desc attribute values ​​of the IED tag in the SCD file. If the name and desc are not standardized, the parsed device type, voltage level, and interval type will be incorrect, which will also affect the manufacturer's ICD device type and the voltage level of the SCD file. Therefore, manual maintenance and modification are required.

[0088] The manufacturer virtual terminals and standard virtual terminals are obtained by parsing the virtual terminal loops between IEDs in the SCD file. If the virtual terminal is named incorrectly (the internal short address of the SV virtual terminal is not specific to the DO (data object) level, and the internal short address of the GOOSE virtual terminal is not specific to the DA (data attribute) level), or the virtual terminal is used incorrectly (as both an input virtual terminal and an output virtual terminal), the extracted virtual terminal information is invalid and needs to be manually modified and confirmed.

[0089] In summary, the core of the solution described in this embodiment is:

[0090] Automatically create standard virtual terminal loops based on SCD files, reducing the workload and complexity of manual creation. Since the correctness of the solution results described in this embodiment mainly depends on the standardization of the SCD file, it is necessary to support manual modification and confirmation to ensure the accuracy of the solution;

[0091] Compared with the traditional construction of standard virtual terminal circuit library, the scheme described in this embodiment establishes and maintains the mapping relationship between standard virtual terminals and manufacturer virtual terminals. The standard virtual terminal circuit library created in this way can be used as the basis for subsequent SCD file hidden danger inspection, and can detect erroneous circuits, missing circuits and redundant circuits in SCD files.
