Description

TECHNICAL FIELD

[0001] The present application relates to power system automation operation and maintenance technology, in particular to a SCD virtual loop configuration method and system based on standardized virtual terminal description and easy-to-construct templates. BACKGROUND

[0002] The virtual terminal of each intelligent electronic device (IED) in the Substation Configuration Description (SCD) file of the intelligent substation and the connection relationship of the virtual terminal affect the switching of the intelligent substation, the sampling loop and the interlocking relationship of the secondary equipment. The correctness of the configuration is crucial to the safe operation of the intelligent substation.

[0003] Since the existing SCD virtual loop automatic connection technology has certain drawbacks in actual engineering applications, some methods need to be based on the identification of references in the IED model to complete automatic wiring, but the current specifications do not make strict requirements on the references in the model, and there is great difference in the references in the models among various suppliers. Relevant design needs to be carried out for each project, or some methods need to identify the template file of a specific carrier, such as.xml format (a general markup language for describing structured data), but the virtual loop connection file provided by the design unit generally uses Excel as the carrier, and the format is mostly.xlsx. It is difficult to complete the conversion between the two, and there is a certain difficulty in the template file production.

[0004] Therefore, at present, the connection of the virtual loop in the SCD file is mostly completed manually by the system integrator according to the virtual loop connection file provided by the design unit through the system configuration tool, which is a heavy task, and the accuracy is difficult to guarantee. Even if a person with extremely high quality level is employed to produce SCD, the probability of human error cannot be avoided. If the problem is not found in time during the debugging process, it will bring hidden dangers to the safe operation of the substation. SUMMARY

[0005] The technical problem to be solved by the present application is to provide a SCD virtual loop configuration method and system based on standardized virtual terminal description and easy-to-construct templates, which does not depend on the references in the IED, and can complete the automatic connection of the SCD virtual loop only by identifying the IEDname and the virtual terminal description. In the case where the virtual terminal description in the IED of the current suppliers is standardized but the references are different, it has good applicability.

[0006] In order to solve the above technical problems, the technical scheme adopted by the present application is: A SCD virtual loop configuration method based on standardized virtual terminal description and easy-to-construct templates, comprising the following steps: Obtain the general design specifications for substations or the virtual loop connection file from the design unit, and design a secondary virtual loop connection file with the same format as the virtual loop connection file; Obtain the IED self-description file and convert it into an SCD file without a configured secondary virtual loop connection. Match the IEDname intervals in the SCD file with the secondary virtual loop connection file to determine the interval that needs to receive virtual terminal connections and the corresponding transmission interval. Match the virtual terminal description name of the interval that needs to receive virtual terminal connections with the secondary virtual loop connection file to obtain the virtual terminal to be received. At the same time, match the virtual terminal description name of the transmission interval with the secondary virtual loop connection file to obtain the virtual terminal to be sent. Based on the virtual terminal connection relationship in the secondary virtual loop connection file, connect the virtual terminal of the receiver to the virtual terminal of the sender.

[0007] Furthermore, the secondary virtual loop connection file includes receiver IEDname information and corresponding sender IEDname information. When obtaining the IED self-description file and converting it into an SCD file without a secondary virtual loop connection, the process includes: parsing the IED information of each interval in the IED self-description file, and generating the IEDname of each interval according to the naming rules of the receiver IEDname information and / or the sender IEDname information.

[0008] Furthermore, when matching the IEDnames in the SCD file with the secondary virtual loop connection file to determine the interval for receiving virtual terminal connections and the corresponding transmission interval, the process specifically includes: if the IEDname of the interval completely matches the receiver IEDname information in the secondary virtual loop connection file, then the interval is the interval for receiving virtual terminal connections; if the IEDname of the interval completely matches the sender IEDname information in the secondary virtual loop connection file, then the interval is the transmission interval.

[0009] Furthermore, the secondary virtual loop connection file includes virtual terminal type information and receiver virtual terminal name information corresponding to the receiver IEDname information. When matching the virtual terminal description name of the interval that needs to receive virtual terminal connections with the secondary virtual loop connection file to obtain the receiver virtual terminal, specifically, an Inputs node is created in the SCD file according to the virtual terminal type information corresponding to the interval that needs to receive virtual terminal connections. Then, the receiver virtual terminal name information corresponding to the interval that needs to receive virtual terminal connections is matched with the description in the desc attribute field of the LLN0 logic node of the interval that needs to receive virtual terminal connections. The parameter corresponding to the matched description is taken as the receiver virtual terminal, and the parameter of the receiver virtual terminal is placed under the corresponding Inputs node.

[0010] Further, the SCD file creates the corresponding Inputs node according to the virtual terminal type information corresponding to the interval requiring to receive the virtual terminal connection, specifically, the SCD file creates the Inputs node under the LLN0 logic node under the logical device under the access point corresponding to the virtual terminal type information according to the virtual terminal type information corresponding to the interval requiring to receive the virtual terminal connection.

[0011] Further, if the virtual terminal type information is GOOSE type, the logical device is any one of a protection interface GOOSE logical device, a control and protection interface GOOSE logical device, and a busbar / feeder busbar GOOSE logical device, and if the virtual terminal type information is SV type, the logical device is a protection interface SV logical device or a busbar SV logical device.

[0012] Further, the secondary virtual circuit connection file includes the sender virtual terminal name information corresponding to the sender IEDname information, and when the sender virtual terminal to be sent is matched in the virtual terminal description name of the sending interval according to the secondary virtual circuit connection file, specifically, the sender virtual terminal name information corresponding to the sending interval is matched with the description in the desc attribute field of the LLN0 logic node of the sending interval, and the reference corresponding to the matched description is taken as the sender virtual terminal to be sent.

[0013] The application further provides an SCD virtual circuit configuration system based on the standardized virtual terminal description and the easy-to-construct template, including a processor and a computer readable storage medium, the computer readable storage medium stores a computer program, and the computer program is executed by the processor to realize the SCD virtual circuit configuration method based on the standardized virtual terminal description and the easy-to-construct template.

[0014] The application further provides a computer readable storage medium, which stores a computer program, and the computer program is executed by the processor to realize the SCD virtual circuit configuration method based on the standardized virtual terminal description and the easy-to-construct template.

[0015] The application further provides a computer program product, which includes a computer program, and the computer program is executed by the processor to realize the SCD virtual circuit configuration method based on the standardized virtual terminal description and the easy-to-construct template.

[0016] Compared with the prior art, the application has the following advantages: The application designs secondary virtual circuit connection files based on standardized virtual terminal description, adopts the same carrier as the virtual circuit connection files provided by the design unit, is convenient for converting the required files through the virtual circuit connection files of the design unit, and is applicable between IEDs of different suppliers, and can be repeatedly used in new, improved and expanded projects.

[0017] The application can complete the automatic connection of SCD virtual circuit only by identifying IEDname and virtual terminal description, can replace the work of the integrator to manually connect virtual terminal circuit one by one, reduces the dependence on personnel quality level, not only reduces the complexity of the work, but also better guarantees the accuracy, can quickly and accurately complete the connection of secondary virtual circuit of intelligent substation, and greatly improves the efficiency of the work.

[0021] The application is further described below in combination with the drawings of the specification and specific preferred embodiments, but the protection scope of the application is not limited by this.

[0022] The standardization design specification of intelligent substation in China is increasingly perfect, and the State Grid Corporation of China and the Southern Power Grid Corporation have also successively issued the standardization design specification of secondary devices such as protection, measurement and control, intelligent terminal and merging unit, and have specified the technical principles, design criteria, information specification and virtual terminal description of the devices.

[0023] The virtual terminal information in the IED file includes reference and description, and the final connection is to match the two references of the receiving party and the sending party together, although the references of the same type of virtual terminal of each manufacturer are different, but the reference identified based on the description of the IED file under the determined IEDname is unique.

[0024] Therefore, in view of the problems that the existing SCD virtual loop configuration personnel is highly dependent, the work task is heavy, and the accuracy is difficult to guarantee, and the existing SCD virtual loop automatic connection technology cannot realize engineering popularization and application, the embodiment proposes a SCD virtual loop configuration method based on standardized virtual terminal description and easy-to-construct templates. The standardized virtual terminal description has strong universality in the case that the virtual terminal description of the IED of the current supplier is standardized but the reference is different.

[0025] As shown in Figure 1 The method of the embodiment includes the following steps: S101) Obtain a virtual loop connection file of a general design specification of a substation or a design unit, and design a secondary virtual loop connection file with the same format as the virtual loop connection file; S102) Obtain an IED self-description file and convert it into an SCD file without configured secondary virtual loop connection, match the IEDname of the interval in the SCD file with the secondary virtual loop connection file, to determine the interval that needs to receive virtual terminal connection and the corresponding sending interval, and match the virtual terminal description name of the interval that needs to receive virtual terminal connection with the secondary virtual loop connection file to obtain the to-be-received virtual terminal, and match the virtual terminal description name of the sending interval with the secondary virtual loop connection file to obtain the to-be-sent virtual terminal; S103) According to the virtual terminal connection relationship in the secondary virtual loop connection file, match the reference of the to-be-received virtual terminal with the reference of the to-be-sent virtual terminal, to realize the connection of the to-be-received virtual terminal and the to-be-sent virtual terminal.

[0026] The application designs a secondary virtual loop connection file with the same carrier as the virtual loop connection file provided by the design unit through the above steps. The secondary virtual loop connection file only has standardized description, does not depend on the reference in the IED to identify the virtual terminal, and only needs to identify the IEDname and the virtual terminal description to identify the virtual terminal, so as to extract the related reference to complete the SCD virtual loop automatic connection, which is suitable for different supplier IEDs and can be reused in new, improved and expanded projects.

[0027] The steps will be described in detail below.

[0028] The embodiment designs a secondary virtual loop connection file based on standardized virtual terminal description through step S101, using the standardized virtual terminal description in the virtual loop connection file of the general design specification of the substation or the design unit, and sets the format to.xlsx format, as shown in Figure 2As shown, the file content includes "receiver IEDname", "sender IEDname", "receiver virtual terminal name", "sender virtual terminal name", "virtual terminal type (GOOSE or SV)", and virtual terminal connection relationship between IEDs.

[0029] When designing the secondary virtual circuit connection file by using the standardized virtual terminal description in the substation general design specification, the steps are as follows: S201: According to the substation general design specification of State Grid Corporation of China or China Southern Power Grid Corporation, the number of IEDs in the substation and the virtual terminal connection relationship between the IEDs are confirmed, so as to determine the receiver and the sender. S202: According to the standardized design specification of secondary devices such as protection, measurement and control, intelligent terminal and merging unit in the State Grid Corporation of China or China Southern Power Grid Corporation, the virtual terminal description information of each IED is extracted, so as to know the virtual terminal name and the virtual terminal type, and thus the receiver virtual terminal name, the sender virtual terminal name and the virtual terminal type are obtained. S203: According to the IEDname naming principle defined in the relevant specification, and according to the actual situation of the substation, the IEDname of each IED is formed, so as to obtain the receiver IEDname and the sender IEDname.

[0030] When designing the secondary virtual circuit connection file by using the standardized virtual terminal description in the virtual circuit connection file of the design unit, specifically, the.xlsx format virtual circuit connection file provided by the design unit is obtained, the redundant columns are deleted, the columns including the receiver IEDname information, the sender IEDname information, the receiver virtual terminal name information, the sender virtual terminal name information, the virtual terminal type information and the virtual terminal connection relationship between IEDs are reserved, and the names of the table headers of these columns are modified into "receiver IEDname", "sender IEDname", "receiver virtual terminal name", "sender virtual terminal name" and "virtual terminal type".

[0031] The embodiment realizes the acquisition of the to-be-received virtual terminal and the to-be-sent virtual terminal through step S102, and specifically includes the following steps: S301: An IED self-description file is acquired and converted into an SCD file without configured secondary virtual circuit connection, including: The IED self-description file is imported, the IED information of each interval in the IED self-description file is parsed, and the IEDname of each interval is generated according to the naming rules of the "receiver IEDname" information and / or "sender IEDname" information of the secondary virtual circuit connection file.

[0032] S302: The secondary virtual circuit connection file is imported.

[0033] S303: Determine the interval that needs to receive the virtual terminal connection, specifically comprising: The "receiver IEDname" of the imported secondary virtual circuit connection file is matched with the IEDname of the interval in the SCD file, and if the IEDname of the interval is completely matched with the "receiver IEDname" information in the secondary virtual circuit connection file, the matching is successful, and the matched interval is the interval Rx (x = 1, 2, 3, 4, 5...) that needs to receive the virtual terminal connection.

[0034] S304: Match the secondary virtual circuit connection file in the virtual terminal description name of the interval that needs to receive the virtual terminal connection to obtain the to-be-received virtual terminal, specifically comprising: First, according to the virtual terminal type information corresponding to the interval that needs to receive the virtual terminal connection, the corresponding Inputs node is created in the SCD file, specifically, according to the virtual terminal type information corresponding to the interval that needs to receive the virtual terminal connection, the Inputs node is created under the LLN0 logic node under the logical device under the access point corresponding to the virtual terminal type information in the SCD file.

[0035] For the interval Rx identified as needing to receive the virtual terminal connection, according to the "virtual terminal type" in the imported secondary virtual circuit connection file, the virtual terminal type that the interval Rx needs to receive is confirmed, such as the "virtual terminal type" corresponding to the "receiver IEDname" of the interval in the imported secondary virtual circuit connection file is only GOOSE type, then the interval Rx only needs to receive the GOOSE type virtual terminal connection, for the interval that needs to receive the GOOSE type virtual terminal connection, the Inputs node is created under the logic node LLN0 under the logical device under the G1 access point of the IED in the SCD file, and the logical device includes the protection interface GOOSE logical device (PIGO) or the measurement and control protection interface GOOSE logical device (RPIT) or the busbar / parent GOOSE logical device (MUGO).

[0036] If the "virtual terminal type" corresponding to the "receiver IEDname" of the interval in the imported secondary virtual circuit connection file is only SV type, then the interval Rx only needs to receive the SV type virtual terminal connection, for the interval that needs to receive the SV type virtual terminal connection, the Inputs node is created under the logic node LLN0 under the logical device under the M1 access point of the IED in the SCD file, and the logical device includes the protection interface SV logical device (PISV) or the busbar SV logical device (MUSV).

[0037] If both GOOSE type and SV type are in the interval "virtual terminal type" in the imported secondary virtual circuit connection file, interval Rx needs to receive both GOOSE type and SV type virtual terminal connection, and for the interval that needs to receive both GOOSE type and SV type virtual terminal connection, the above two Inputs nodes are respectively created in the corresponding positions.

[0038] Then, the description in the desc attribute field of the LLN0 logic node of the interval that needs to receive the virtual terminal connection is matched with the receiving virtual terminal name information of the interval that needs to receive the virtual terminal connection, the reference of the matched description is taken as the to-be-receiving virtual terminal, and the reference of the to-be-receiving virtual terminal is placed under the corresponding Inputs node.

[0039] Specifically, for the confirmed interval Rx that needs to receive the virtual terminal connection, the "receiving virtual terminal name" information related to the interval is taken out from the imported secondary virtual circuit connection file through the "receiving IED name" information of the interval, the description matched with the "receiving virtual terminal name" information is searched in each desc field in the logic node LLN0 of the interval in the SCD file, the reference of the matched result is taken as the to-be-receiving virtual terminal, and the reference of the to-be-receiving virtual terminal is placed under the created Inputs node according to the "virtual terminal type" information.

[0040] S305: Determine the sending interval, and match the secondary virtual circuit connection file in the virtual terminal description name of the sending interval to obtain a to-be-sending virtual terminal, specifically including: For the confirmed interval Rx that needs to receive the virtual terminal connection, the "receiving IED name" information of the interval is taken out from the imported secondary virtual circuit connection file, and the "sending IED name" information and the corresponding "sending virtual terminal name" information related to the interval are taken out. The "sending IED name" information is matched with the IEDname of the interval in the SCD file, and if the IEDname of the interval is completely matched with the "sending IED name" information in the secondary virtual circuit connection file, the matching is successful, and the matched interval is the sending interval Sy (y=1, 2, 3, 4, 5...) corresponding to the interval Rx. The "sending virtual terminal name" information is matched with the desc attribute field of the LLN0 logic node of the sending interval Sy, and the reference of the matched description is taken as the to-be-sending virtual terminal. That is, the description matched with the "sending virtual terminal name" information is searched in each desc attribute field in the logic node LLN0 of the interval Sy in the SCD file, and the reference of the matched result is taken as the to-be-sending virtual terminal.

[0041] The embodiment realizes automatic connection by step S103, including the following steps: S401: according to the virtual terminal connection relationship between IEDs in the imported secondary virtual circuit connection file, the reference between the to-be-received virtual terminal and the to-be-sent virtual terminal is one-to-one mapped to complete automatic connection; S402: in the automatic connection process, whether the connection is consistent with the virtual circuit information in the imported secondary virtual circuit connection file is counted, if the connection fails, the number of failures is prompted, and an error report is output in a separate file to prompt the failure reason, and the final connection result is as shown in Figure 3 S403: for the SCD file of the completed secondary virtual circuit connection, the secondary virtual circuit connection file can also be exported according to the interval or the whole station, which is used to compare the correctness of the connection or continue to be used in new, improved and expanded projects.
