Description

Technical Field

[0001] This invention belongs to the field of intelligent substation configuration and engineering verification technology, and particularly relates to a verification method and system for a main transformer circuit. Background Technology

[0002] In smart substations, virtual circuits serve as the core carriers for realizing secondary functions such as relay protection and measurement and control. The correctness of their configuration directly affects the safe and stable operation of the power grid. As a key piece of equipment in the substation, the main transformer (referred to as "main transformer") has a complex protection circuit structure and diverse types (such as autotransformers, three-winding transformers, two-winding transformers, etc.), and may be configured with a main body merging unit, which makes the configuration verification of the main transformer virtual circuits a huge challenge.

[0003] Currently, main transformer circuit verification mainly relies on manual comparison or automated verification tools based on fixed templates. Manual verification is inefficient, error-prone, and highly dependent on human experience. Existing automated verification tools typically cannot intelligently identify the specific type and configuration of the main transformer, often requiring manual pre-specification of circuit templates. When the main transformer type is incorrectly identified or the template is inappropriately selected, it can lead to numerous false alarms (such as misjudging correct special configurations as missing or incorrect connections), making the verification results unreliable. Ultimately, extensive manual review is still required, failing to fully leverage the advantages of automated verification.

[0004] Therefore, there is an urgent need in this field for an intelligent verification method that can automatically identify the actual connection characteristics of the main transformer circuit and dynamically adjust the verification strategy accordingly, so as to improve the accuracy and efficiency of the verification. Summary of the Invention

[0005] This invention provides a verification method and system for main transformer circuits to solve the problems of low verification accuracy, numerous false alarms, and insufficient automation caused by the complexity and variety of main transformer types and configurations in the prior art.

[0006] In a first aspect, the present invention provides a verification method for a main transformer circuit, comprising:

[0007] A full virtual circuit template for the main transformer is pre-established. The full virtual circuit template for the main transformer contains the standard virtual circuit connection relationship that should be met between the main transformer protection and the associated secondary equipment. The associated secondary equipment includes at least one of the following: main body merging unit, merging units on each side, and intelligent terminal.

[0008] Parse the SCD configuration file to be verified and extract the actual virtual connection information of the main transformer protection device, including virtual terminal description information and sender IED device attributes;

[0009] Based on the actual virtual connection information, by analyzing the virtual terminal description keywords and the sender IED attributes, the loop connection type of the main transformer protection in the current SCD configuration is identified and determined. The connection type is identified by one or more of the predefined feature codes.

[0010] The actual virtual connection information is compared with the main transformer full virtual circuit template, and based on the identified circuit connection type, the corresponding verification logic rules are dynamically adapted to generate and output the verification result for the correctness of the virtual circuit connection.

[0011] Secondly, the present invention provides a verification system for a main transformer circuit, comprising:

[0012] A module is configured to pre-establish a full virtual circuit template for the main transformer. The full virtual circuit template for the main transformer contains the standard virtual circuit connection relationship that should be met between the main transformer protection and the associated secondary equipment. The associated secondary equipment includes at least one of the following: a main body merging unit, merging units on each side, and a smart terminal.

[0013] The parsing module is configured to parse the SCD configuration file to be verified and extract the actual virtual connection information of the main transformer protection device, including virtual terminal description information and sender IED device attributes;

[0014] The identification module is configured to identify and determine the circuit connection type of the main transformer protection in the current SCD configuration based on the actual virtual connection information by analyzing the virtual terminal description keywords and the sender IED attributes. The connection type is identified by one or more of a predefined set of feature codes.

[0015] The generation module is configured to compare the actual virtual connection information with the main transformer full virtual circuit template, and dynamically adapt the corresponding verification logic rules based on the identified circuit connection type to generate and output the verification result for the correctness of the virtual circuit connection.

[0016] Thirdly, an electronic device is provided, comprising: at least one processor, and a memory communicatively connected to the at least one processor, wherein the memory stores instructions executable by the at least one processor, the instructions being executed by the at least one processor to enable the at least one processor to perform the steps of the verification method for the main transformer circuit of any embodiment of the present invention.

[0017] Fourthly, the present invention also provides a computer-readable storage medium having a computer program stored thereon, wherein when the program instructions are executed by a processor, the processor performs the steps of the verification method for the main transformer circuit of any embodiment of the present invention.

[0018] The main transformer circuit verification method and system of this application introduces a feature-code-based intelligent identification mechanism for circuit connection types by constructing a full virtual circuit template library for the main transformer and automatically parsing the actual configuration in the SCD file. This mechanism can accurately determine the specific connection characteristics of the main transformer protection in terms of common winding current, zero-sequence and gap current sources, sampling type completeness, and voltage side selection. On this basis, the verification process does not mechanically perform template matching, but dynamically adapts and executes differentiated verification logic rules according to the identified connection types. This achieves accurate understanding and intelligent fault tolerance for various special configuration scenarios of the main transformer (such as only receiving zero-sequence current from the main body merging unit, only pulling single-sided sampling, etc.). Ultimately, while comprehensively improving the automation level of verification, it fundamentally and significantly reduces false alarms and missed alarms caused by configuration diversity, resulting in a qualitative leap in the accuracy and reliability of verification results. It also greatly reduces the dependence on human experience and effectively ensures the correctness of the virtual circuit configuration and operational safety of the main transformer protection system in smart substations.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Please see Figure 1 The diagram shows a flowchart of a verification method for a main transformer circuit according to this application.

[0025] like Figure 1As shown, the verification method for the main transformer circuit specifically includes the following steps:

[0026] Step S101: A full virtual circuit template for the main transformer is pre-established. The full virtual circuit template for the main transformer contains the standard virtual circuit connection relationship that should be met between the main transformer protection and the associated secondary equipment. The associated secondary equipment includes at least one of the following: main body merging unit, merging units on each side, and intelligent terminal.

[0027] Step S102: Parse the SCD configuration file to be verified and extract the actual virtual connection information of the main transformer protection device, including virtual terminal description information and sender IED device attributes.

[0028] Step S103: Based on the actual virtual connection information, by analyzing the virtual terminal description keywords and the sender IED attributes, identify and determine the loop connection type of the main transformer protection in the current SCD configuration. The connection type is identified by one or more of the predefined feature codes.

[0029] In this step, the first feature code indicates whether the main transformer protection draws the common winding current;

[0030] The second feature code indicates whether the main transformer protection has not drawn the common winding current.

[0031] The third feature code indicates whether the main transformer protection receives zero-sequence current or gap current from the main body merging unit;

[0032] Fourth feature code: indicates whether the main transformer protection receives zero-sequence current or gap current from each side merging unit;

[0033] Fifth feature code: Indicates whether the main transformer protection only draws current samples and not voltage samples;

[0034] The sixth feature code indicates whether the main transformer protection draws current samples from only a single voltage side;

[0035] The seventh feature code indicates whether the main transformer protection has not taken any current or voltage samples;

[0036] The eighth feature code indicates whether the main transformer protection only retrieves the rated delay parameters of each side.

[0037] Specifically, the specific methods for identifying the loop connection type include:

[0038] If the virtual terminal description in the actual virtual connection information contains the keyword "common winding current", then the connection type is determined to contain the first feature code; if none of the actual virtual connections contain this keyword, then the connection type is determined to contain the second feature code.

[0039] If a virtual terminal description contains the keywords of zero-sequence current or gap current, the determination is made according to the type of the transmitting IED: if the transmitting party is a main body merging unit, the connection type is determined to contain the third feature code; if the transmitting party is a side merging unit, the connection type is determined to contain the fourth feature code.

[0040] If a virtual terminal description contains the current keyword, and all actual virtual connections do not contain the voltage keyword, then the connection type is determined to contain the fifth feature code.

[0041] If a virtual terminal description contains the keyword "current", and the voltage level attribute of all transmitting IEDs is unique, then the connection type is determined to contain the sixth feature code.

[0042] If none of the virtual terminal descriptions of all actual virtual connections contain the keywords for current, voltage, and rated delay, then the connection type is determined to contain the seventh feature code.

[0043] If a virtual terminal description contains the keyword "rated delay" and the number of rated delays for each voltage level is 1, then the connection type is determined to contain the eighth feature code.

[0044] Step S104: Compare the actual virtual connection information with the main transformer full virtual circuit template, and dynamically adapt the corresponding verification logic rules based on the identified circuit connection type to generate and output the verification result for the correctness of the virtual circuit connection.

[0045] In this step, the dynamic adaptation verification logic rules include:

[0046] When the connection type contains the second feature code, the missing connection alarm for the virtual connection involving the common winding current in the main transformer full virtual circuit template is canceled.

[0047] When the connection type contains a third feature code, the missing connection alarm for the virtual connection involving the zero-sequence current or gap current of each side merging unit in the template is canceled, and the corresponding circuit involving the main body merging unit in the actual connection is checked for misconnection.

[0048] When the connection type contains the fourth feature code, the missing connection alarm for the virtual connection involving the zero-sequence current or gap current of the body merging unit in the template is canceled, and the corresponding circuits involving the merging units on each side in the actual connection are checked for misconnection.

[0049] When the connection type contains the fifth feature code, cancel the missing connection alarm for the virtual connection involving voltage sampling in the template.

[0050] When the connection type contains the sixth feature code, cancel the missing connection alarm for the current and voltage sampling virtual connections in the template that are not related to the current voltage level.

[0051] When the connection type contains the seventh feature code, only the current loops on each side of the template are checked for missing connections.

[0052] When the connection type contains the eighth feature code, only the high-voltage side current loop in the template is checked for missing connections.

[0053] Specifically, the process of generating the verification results includes:

[0054] Traverse the actual virtual connection information and match it one by one with the main transformer full virtual loop template:

[0055] If the actual connection matches the template definition perfectly and the terminal correspondence is consistent, it is marked as normal;

[0056] If the actual connection is not defined in the template, it is marked as a multiple connection;

[0057] If the actual connection does not match the template definition or the terminal correspondence is inconsistent, it is marked as an incorrect connection;

[0058] Traverse the virtual connections defined in the main transformer full virtual loop template and check whether they exist in the actual SCD configuration:

[0059] Apply the corresponding missing connection judgment rules according to the circuit connection type;

[0060] Virtual connections that meet the criteria for missing connections are marked as missing connections.

[0061] In summary, the method of this application, by constructing a full virtual circuit template library for the main transformer and automatically parsing the actual configuration in the SCD file, introduces a feature-based intelligent identification mechanism for circuit connection types. This mechanism can accurately determine the specific connection characteristics of the main transformer protection in terms of common winding current, zero-sequence and gap current sources, sampling type completeness, and voltage side selection. Furthermore, the verification process does not mechanically match templates but dynamically adapts and executes differentiated verification logic rules based on the identified connection types. This achieves accurate understanding and intelligent fault tolerance for various special configuration scenarios of the main transformer (such as receiving only the zero-sequence current of the main transformer merging unit or only pulling single-sided sampling). Ultimately, while comprehensively improving the automation level of verification, it fundamentally and significantly reduces false alarms and missed alarms caused by configuration diversity, resulting in a qualitative leap in the accuracy and reliability of verification results. It also greatly reduces the reliance on human experience, effectively ensuring the correctness of the virtual circuit configuration and operational safety of the main transformer protection system in the intelligent substation.

The associated secondary equipment includes at least one of a main body merging unit, side merging units, and intelligent terminals; Module 220, configured to parse the SCD configuration file to be verified, extracting the actual virtual connection information of the main transformer protection equipment, including virtual terminal description information and sender IED device attributes; Module 230, configured to, based on the actual virtual connection information, identify and determine the circuit connection type of the main transformer protection in the current SCD configuration by analyzing virtual terminal description keywords and sender IED attributes. The connection type is identified by one or more predefined feature codes; and Module 240, configured to compare the actual virtual connection information with the full virtual circuit template for the main transformer, and, based on the identified circuit connection type, dynamically adapt the corresponding verification logic rules to generate and output verification results for the correctness of the virtual circuit connections.
