Description

Technical Field

[0001] This invention relates to the field of power system substation configuration file management technology, and in particular to an online management method and system for substation configuration files. Background Technology

[0002] With the in-depth upgrading of power information construction, smart substations have become increasingly reliant on equipment automation and intelligence. The accuracy and real-time status of data in SCD (Substation Configuration Description), CCD (Coupling-Circuit Description), and CID (Configured IED Description) files play an important role in the normal operation and maintenance of substations. IED stands for Intelligent Electronic Device.

[0003] Traditional control systems employ an offline management model of "offline file upload." This involves staff using specialized tools to export configuration files from substations or secondary equipment to physical storage media on-site. The physical storage media is then brought back to the computer running the configuration file management system, where the configuration files are uploaded and managed through check-in / check-out operations. This method has significant limitations: due to the inherent lag and subjectivity of manual operation, the configuration file management system lacks a real-time data linkage mechanism with substation equipment. As the number of configuration file changes and update frequencies increases, discrepancies can easily arise between the configuration files managed by the system and the actual effective configuration files on-site, thus affecting the normal operation of the substation. Furthermore, it significantly increases the workload and operational difficulty for configuration file maintenance personnel. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide an online management method and system for substation configuration files that can automatically summon configuration files of substation field equipment, reduce the workload and operational difficulty of configuration file maintenance personnel, and promptly detect differences between the control configuration file and the actual configuration files used by substation field equipment.

[0005] A method for online management and control of substation configuration files includes the following steps: S101, after a communication recovery event occurs, the secondary device involved in the communication recovery event is taken as the target secondary device. The target secondary device sends a first type of message with its own unique identification information to the control cloud according to the preset control transmission protocol. S102, after the configuration file management module detects that the control cloud has received the first type of message, it obtains and parses the first type of message to get the identification information of the target secondary device, and based on the identification information, it calls the target secondary device to obtain the configuration file it is currently using. The configuration file management module is configured to continuously monitor the control cloud. S103, the configuration file management module obtains the identification information of the target secondary device, reads the corresponding control configuration file stored on the configuration file management module, and performs a consistency check between the control configuration file and the configuration file currently used by the target secondary device obtained by the call; S104 archives management configuration files that pass consistency verification and generates alarm information for management configuration files that fail consistency verification.

[0006] As a further improvement to the above technical solution: In step S101, the first type of message is forwarded to the control cloud via a chain communication path that passes through the target secondary device, substation, branch station, main station and control cloud.

[0007] Step S102, which involves calling the target secondary device to obtain its currently used configuration file, includes the following steps: S201, the configuration file management module generates a second type of message with target secondary device identification information according to the preset control transmission protocol, and the second type of message is transmitted to the main station through the control cloud; S202, after receiving the second type of message, the master station parses it to obtain the identification information of the target secondary device, locates the target substation based on the identification information, and forwards the second type of message to the target substation; S203, after receiving the second type of message, the target substation parses it to obtain the identification information of the target secondary device, locates the target substation based on the identification information, and forwards the second type of message to the target substation; S204 After receiving the second type of message, the target substation parses it to obtain the identification information of the target secondary device. After locating the target secondary device based on the identification information, it sends a request to obtain the configuration file to the target secondary device. S205, after receiving the request to obtain the configuration file, the target secondary device sends the configuration file it is currently using to the target substation; S206, The target substation will obtain the configuration file currently used by the target secondary equipment and upload it to the target substation and the target main station in sequence, and finally store it in the control cloud; 207. The configuration file management module obtains the storage address of the target secondary device's configuration file in the control cloud and downloads the target secondary device's configuration file to the local preset directory.

[0008] The configuration file currently used by the target secondary device includes a CCD file, a CID file, and a verification code; Step S103 includes the following steps: S301, the configuration file management module reads the control SCD file stored locally in the substation to which the target secondary device belongs, based on the identification information of the target secondary device; S302, based on the identification information of the target secondary device, export the CCD file corresponding to the target secondary device from the control SCD file as the control CCD file of the target secondary device, export the CID file corresponding to the target secondary device as the control CID file of the target secondary device, and export the check code corresponding to the target secondary device as the control check code of the target secondary device; S303, perform consistency verification between the control CCD file of the target secondary device and the CCD file currently used by the target secondary device obtained by the call; perform consistency verification between the control CID file of the target secondary device and the CID file currently used by the target secondary device obtained by the call; perform consistency verification between the control verification code of the target secondary device and the verification code currently used by the target secondary device obtained by the call. S304. If all the checks in step S303 pass, the control configuration file is determined to have passed the consistency check; otherwise, the control configuration file is determined to have failed the consistency check.

[0009] The consistency verification between the control CCD file of the target secondary device and the CCD file of the target secondary device obtained by the call includes: comparing the names of each element, the order of elements, the attribute names of elements, the order of attributes, and the correspondence between attribute names and attribute values ​​in the control CCD file of the target secondary device and the CCD file currently used by the target secondary device obtained by the call, line by line. If the content of the two types of CCD files is the same in the same line, the line is marked as consistent; otherwise, it is marked as inconsistent and the specific difference category is marked. If all lines are marked as consistent, the verification is considered to have passed. The consistency verification between the control CID file of the target secondary device and the CID file currently used by the target secondary device obtained through the call includes: comparing line by line the name of each element, the order of elements, the attribute name of elements, the order of attributes, and the correspondence between attribute names and attribute values ​​in the control CID file of the target secondary device and the CID file currently used by the target secondary device obtained through the call. If the content of the two types of CID files is the same in the same line, the line is marked as consistent; otherwise, it is marked as inconsistent and the specific difference category is indicated. If all lines are marked as consistent, the verification is considered to have passed.

[0010] The consistency verification between the control CCD file of the target secondary device and the CCD file of the target secondary device obtained through the call also includes: identifying the optical port configuration information in the two types of CCD files, extracting the optical port configuration information from the two types of CCD files, and comparing line by line the name of each element, the order of elements, the attribute name of elements, the order of attributes, and the correspondence between attribute names and attribute values ​​in the control CID file of the target secondary device from which the optical port configuration information has been extracted and the CID file currently used by the target secondary device obtained through the call. If the content of the two types of CID files with the optical port configuration information extracted in the same line is the same, then the line is marked as consistent; otherwise, it is marked as inconsistent and the specific difference category is indicated at the same time.

[0011] The communication recovery events in step S101 include: recovery after communication interruption between secondary equipment and substation, recovery after communication interruption between master station and substation, identification of secondary equipment tag cancellation signal, and recovery after communication interruption between configuration file management module and control cloud; step S101 also includes: after an SCD file change event occurs at substation, the secondary equipment belonging to that substation will be used as the target secondary equipment.

[0012] If the communication recovery event is the recovery of communication between the main station and the substation after an interruption, or the recovery of communication between the configuration file management module and the control cloud after an interruption, or an SCD file change event occurs in the substation, in step S102, the configuration file management module will also call to obtain the configuration file currently used by the substation to which the target secondary device belongs. In step S103, the consistency verification will be performed between the control configuration file and the configuration file currently used by the target secondary device and the configuration file currently used by the substation to which the target secondary device belongs.

[0013] In addition, the present invention also provides an online management and control system for substation configuration files, including a microprocessor and a memory interconnected thereto, wherein the microprocessor is programmed or configured to execute the above-described online management and control method for substation configuration files.

[0014] In addition, the present invention provides a computer-readable storage medium storing a computer program or instructions that are programmed or configured to execute the above-described online management and control method for substation configuration files via a processor.

[0015] Compared with the prior art, the present invention can mainly achieve the following beneficial effects: This invention replaces the traditional manual on-site extraction, offline transmission, and manual import process by automatically sending identified messages from the target secondary equipment and automatically parsing the summoning file through the configuration file management module. This reduces the workload and operational difficulty for configuration file maintenance personnel, while also reducing the risk of mistransmission or omission. For control configuration files that fail the consistency check, alarm information is generated. Configuration file maintenance personnel can locate the secondary equipment with discrepancies based on the alarm information for subsequent processing, which is beneficial to the stability and safety of substation operation.

[0017] Figure 2 This is a schematic diagram of the network topology of the substation of the present invention.

[0018] Figure 3 This is a schematic diagram of the process for verifying the consistency of configuration files in this invention. Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of the present invention clearer, specific embodiments will be described below in conjunction with the accompanying drawings.

[0020] like Figure 1 As shown, the online management method for substation configuration files in this embodiment includes the following steps: S101, after a communication recovery event occurs, the secondary device involved in the communication recovery event is taken as the target secondary device. The target secondary device sends a first type of message with its own unique identification information to the control cloud according to the preset control transmission protocol. S102, after the configuration file management module hears that the control cloud has received the first type of message, it obtains and parses the first type of message to get the identification information of the target secondary device, and based on the identification information, it calls the target secondary device to obtain the configuration file it is currently using. The configuration file management module is configured to continuously listen to the control cloud. S103, the configuration file management module obtains the identification information of the target secondary device, reads the corresponding control configuration file stored on the configuration file management module, and performs a consistency check between the control configuration file and the configuration file currently used by the target secondary device obtained by the call; S104 archives management configuration files that pass consistency verification and generates alarm information for management configuration files that fail consistency verification.

[0021] It should be noted that secondary equipment refers to electrical equipment and systems used to monitor, control, protect, and measure the operating status of primary equipment (such as transformers, circuit breakers, disconnect switches, and other equipment that directly carry electrical energy) and to realize the automated operation and maintenance and safety management of substations. This includes various protection devices, measurement and control devices, intelligent terminals, merging units, etc. The configuration file management module includes the configuration file management system and the computer running the system. The secondary equipment involved in the communication recovery event specifically refers to the secondary equipment whose network link with the configuration file management module was interrupted and then reconnected. If the communication between the main station and the substation was interrupted and then restored, then all secondary equipment in that substation is involved. If the network link between the main station and the control cloud was interrupted and then restored, or the communication between the configuration file management module and the control cloud was interrupted and then restored, then all secondary equipment in all substations under the main station is involved. In this embodiment, communication recovery events include: recovery after communication interruption between secondary equipment and substation, recovery after communication interruption between the main station and substation, identification of a secondary equipment tag cancellation signal, and recovery after communication interruption between the configuration file management module and the control cloud.

[0022] The online management method for substation configuration files in this embodiment automatically sends tagged messages from target secondary devices and automatically parses and retrieves files through the configuration file management module. This replaces the traditional manual on-site extraction, offline transmission, and manual import process, thereby reducing the workload and operational difficulty for configuration file maintenance personnel and also reducing the risk of mistransmission or omission. For management configuration files that fail the consistency check, alarm information is generated. Configuration file maintenance personnel can locate the secondary devices with discrepancies based on the alarm information for subsequent processing, which is beneficial to the stability and safety of substation operation.

[0023] Furthermore, in this embodiment, in step S101, the first type of message is forwarded to the control cloud via a chain communication path consisting of the target secondary device, substation, branch station, master station, and control cloud. That is, the first type of message is initiated by the target secondary device, received and forwarded by the substation to the branch station, then uploaded by the branch station to the master station, and finally pushed to the control cloud by the master station. The network topology of the substation in this embodiment is shown in [reference needed]. Figure 2 The configuration file management module is deployed on the control cloud side and establishes a communication connection with it. A positive and negative isolation device is installed between the control cloud and the main station. It should be noted that the substations in the above topology are optional nodes. In some smaller substations or substations with simplified network architectures, substations may not be set up. In this case, the transmission path of the first type of message will be simplified to "secondary equipment → substation → main station → control cloud," with the substation directly establishing a communication connection with the main station to complete information forwarding. It should be noted that the secondary equipment, substations, substations, and main station belong to Zone 2 of the substation, while the control cloud and configuration file management module belong to Zone 3 of the substation.

[0024] As an optional implementation, a transparent transmission channel is established between the substation and the main station. The substation only maintains the communication link with the secondary device. After receiving information from the secondary device, it transmits it to the main station without modification. The substation only retains the communication parameters with the secondary device. The main station then builds a dedicated data acquisition framework for the data transparently transmitted from the substation, which can effectively reduce the maintenance and configuration work of the substation.

[0025] Furthermore, in this embodiment, step S102, which involves calling upon the target secondary device to obtain its currently used configuration file, includes the following steps: S201, the configuration file management module generates a second type of message with target secondary device identification information according to the preset control transmission protocol, and the second type of message is transmitted to the main station through the control cloud; S202, after receiving the second type of message, the master station parses it to obtain the identification information of the target secondary device, locates the target substation based on the identification information, and forwards the second type of message to the target substation; S203, after receiving the second type of message, the target substation parses it to obtain the identification information of the target secondary device, locates the target substation based on the identification information, and forwards the second type of message to the target substation; S204 After receiving the second type of message, the target substation parses it to obtain the identification information of the target secondary device. After locating the target secondary device based on the identification information, it sends a request to obtain the configuration file to the target secondary device. S205, after receiving the request to obtain the configuration file, the target secondary device sends the configuration file it is currently using to the target substation; S206, The target substation will obtain the configuration file currently used by the target secondary equipment and upload it to the target substation and the target main station in sequence, and finally store it in the control cloud; 207. The configuration file management module obtains the storage address of the target secondary device's configuration file in the control cloud and downloads the target secondary device's configuration file to the local preset directory.

[0026] Corresponding to the previous paragraph, through the parsing of identification information and the step-by-step positioning mechanism, each node only needs to accurately forward the second type of message to the next level according to the identification information, thereby ensuring that the final request to obtain the configuration file is accurately delivered to the target secondary device and reducing the risk of mistransmission; the target substation will upload the configuration file currently used by the target secondary device through the target substation and the target main station and finally store it in the control cloud. The configuration file management module can download the required configuration file from the control cloud according to its own storage space size, which is flexible and convenient to use.

[0027] Furthermore, in this embodiment, the configuration file currently used by the target secondary device includes a CCD file, a CID file, and a checksum (specifically a CRC code, Cyclic Redundancy Check). The checksum is a specific code generated to verify the integrity of the CCD file and the CID file. See Figure 3 Step S103 includes the following steps: S301, the configuration file management module reads the control SCD file stored locally in the substation to which the target secondary device belongs, based on the identification information of the target secondary device; S302, based on the identification information of the target secondary device, export the CCD file corresponding to the target secondary device from the control SCD file as the control CCD file of the target secondary device, export the CID file corresponding to the target secondary device as the control CID file of the target secondary device, and export the check code corresponding to the target secondary device as the control check code of the target secondary device (see...). Figure 3 Export the control CCD file, CID file, and control verification code of the target secondary device through the IED configuration tool (e.g., extract relevant information of the target secondary device using a Java XML parsing library). S303, perform consistency verification between the control CCD file of the target secondary device and the CCD file currently used by the target secondary device obtained by the call; perform consistency verification between the control CID file of the target secondary device and the CID file currently used by the target secondary device obtained by the call; perform consistency verification between the control verification code of the target secondary device and the verification code currently used by the target secondary device obtained by the call. S304. If all the checks in step S303 pass, the control configuration file is determined to have passed the consistency check; otherwise, the control configuration file is determined to have failed the consistency check.

[0028] Specifically, the consistency verification between the control CCD file of the target secondary device and the CCD file of the target secondary device obtained by the call includes: comparing line by line the name of each element, the order of elements, the attribute name of elements, the order of attributes, and the correspondence between attribute names and attribute values ​​in the control CCD file of the target secondary device and the CCD file currently used by the target secondary device obtained by the call. If the content of the two types of CCD files is the same in the same line, the line is marked as consistent; otherwise, it is marked as inconsistent and the specific difference category is marked. If all lines are marked as consistent, the verification is considered to have passed. The consistency verification between the control CID file of the target secondary device and the CID file currently used by the target secondary device obtained through the call includes: comparing line by line the name of each element, the order of elements, the attribute name of elements, the order of attributes, and the correspondence between attribute names and attribute values ​​in the control CID file of the target secondary device and the CID file currently used by the target secondary device obtained through the call. If the content of the two types of CID files is the same in the same line, the line is marked as consistent; otherwise, it is marked as inconsistent and the specific difference category is indicated. If all lines are marked as consistent, the verification is considered to have passed.

[0029] Corresponding to the previous paragraph, by comparing and marking line by line, when there are differences between two types of CCD files and two types of CID files, the location and items of the differences can be found in a timely manner, which facilitates subsequent investigation and handling of the causes of the differences.

[0030] Furthermore, in this embodiment, the consistency verification between the control CCD file of the target secondary device and the CCD file of the target secondary device obtained through a call includes: identifying the optical port configuration information in the two types of CCD files, extracting the optical port configuration information from the two types of CCD files, and comparing line by line the names of each element, the order of elements, the attribute names of elements, the order of attributes, and the correspondence between attribute names and attribute values ​​in the control CID file of the target secondary device from which the optical port configuration information has been extracted and the CID file currently used by the target secondary device obtained through a call. If the content of the two types of CID files with the extracted optical port configuration information in the same line is the same, then that line is marked as consistent; otherwise, it is marked as inconsistent and the specific difference category is indicated. Since the optical port configuration information may have reasonable differences due to temporary debugging or link switching, extracting this part of the content before comparison makes it easier for staff to quickly locate the root cause of the problem and shorten the subsequent rectification cycle.

[0031] Step S101 further includes: after an SCD file change event occurs at a substation, the secondary device belonging to that substation is designated as the target secondary device. If the communication recovery event is a recovery after a communication interruption between the master station and the substation, or a recovery after a communication interruption between the configuration file management module and the control cloud, or an SCD file change event occurs at a substation, in step S102, the configuration file management module will also retrieve the configuration file (specifically, the SCD file) currently used by the substation to which the target secondary device belongs. In step S103, the consistency verification is performed between the control configuration file and the retrieved configuration file currently used by the target secondary device and the configuration file currently used by the substation to which the target secondary device belongs. Step S303 further includes performing a consistency verification between the control SCD file and the retrieved SCD file currently used by the substation to which the target secondary device belongs.

[0032] As an optional implementation, the control transmission protocol specifies that the content of Type I and Type II messages includes a frame header, frame length, command code, parameters, and checksum. Specifically, the frame header occupies two bytes and includes a specific byte sequence used to uniquely identify the transmission. The frame length field indicates the total length of the frame and determines the end position of the frame. The command code defines the function of the frame, using SCDB001 to represent a communication recovery event signal or a substation SCD file change event, and SCDB002 to represent a file recall signal. That is, command code SCDB001 represents a Type I message, and command code SCDB002 represents a Type II message. The parameter section carries different parameters depending on the command. The data of different types is parsed by the receiver as a condition for instruction response processing. The parameters of the first type of message include the substation name (or the name of the substation to which it belongs), the secondary equipment type, and the secondary equipment name. These three parameters are the identification information of this implementation. The parameters of the second type of message include the substation name (or the name of the substation to which it belongs), the secondary equipment type, the secondary equipment name, and the configuration file category. The configuration file category can be one or more of SCD, CCD, CID, and CRC. Generally, the configuration file category is selected as CCD, CID, or CRC to retrieve the CCD file, CID file, and check code (Cyclic Redundancy Check) currently used by the target secondary equipment. When the configuration file category is SCD, CCD, CID, and CRC, in addition to retrieving the CCD file, CID file, and check code currently used by the target secondary equipment, the SCD file currently used by the substation to which the target secondary equipment belongs will also be retrieved.

[0033] As an optional implementation, the parameters of the first type of message also include an event category. The event category can be selected as follows: recovery after communication interruption between the secondary device and the substation; recovery after communication interruption between the master station and the substation; detection of a secondary device tag cancellation signal; recovery after communication interruption between the configuration file management module and the control cloud; and SCD file change at the substation. After the configuration file management module parses the event category of the first type of message, if the event category is recovery after communication interruption between the secondary device and the substation, it only requests the configuration file currently used by the target secondary device. If the event category is other, it also requests the configuration file currently used by the substation to which the target secondary device belongs (corresponding to...).
