Especially in the context of the new generation of substations that pursue self-control, safety, and reliability, traditional substations will gradually be replaced, which has become the trend of the next-step substation construction. Therefore, the need for substation monitoring system transformation has become increasingly urgent. Before a substation is officially put into use, it is necessary to accept the substation system.

[0022] The method for verifying data consistency based on the RCD file provided in this embodiment is based on the RCD file. The simulation test system is used to send telemetry and telecontrol signal data to two data network shutdown devices before and after the upgrade. The simulation master station generates a simulation master station record file and compares the generated simulation master station to verify the data consistency of the telemetry and telecontrol signal data of the data network shutdown device before and after the upgrade; the simulation master station sends remote control data to two data network shutdown devices before and after the upgrade, and the simulation test system generates a remote control record file and compares the generated remote control record file to verify the data consistency of the remote control data of the data network shutdown device before and after the upgrade. It realizes the verification of data consistency before and after the transformation and upgrade of the network shutdown device by means of automation, without the need for cumbersome manual point-to-point operations, with high verification efficiency, high verification accuracy, and can effectively shorten the transformation verification cycle.

[0023] Next, the technical solutions and technical effects of the present invention will be further described through specific examples and specific application scenarios. The following examples are explanations of the present invention, and the present invention is not limited to the following examples.

[0024] In this embodiment, the RCD file is defined in the power industry standard "Q_GDW 11627-2016 Technical Specification for Substation Data Communication Network Shutdown Device", which represents the Remote Configuration Description file. The content of the RCD file includes basic information, version information, combined signal information, telemetry forwarding information, telecontrol signal forwarding information, remote control forwarding information, teleadjustment forwarding information, etc. Each data network shutdown device channel corresponds to an RCD file.

[0025] SCD file stands for System Configuration Description, which is a file type defined by IEC61850 standard. It is used to describe the configuration of smart substation, including primary system configuration, secondary equipment related information configuration and communication network configuration. In debugging, SCD file is very important. It is used to establish the whole station model and describe the relationship between all IED devices. It plays a key role in the troubleshooting of relay protection commissioning personnel. In the debugging process of smart substation, SCD file plays a vital role. It is a file of all configurations of the whole station, usually only one, describing all configurations related to substation automation system, including subsystem model, communication network configuration, device instance configuration, LN function allocation, GOOSE configuration, SMV configuration, etc. Therefore, for the relay protection commissioning personnel of smart substation, it is very important to be familiar with the configuration of SCD file of the whole station and to clarify the location of the objects described in SCD file in the whole station, which is very important for debugging and troubleshooting. Through SCD file, all configuration data of substation can also be obtained.

[0026] This embodiment provides a data consistency verification method based on RCD files, which is used to verify the consistency of data gateway machine data before and after the substation upgrade, including online dynamic telemetry and telesignaling verification based on RCD files and online dynamic remote control verification based on RCD files.

[0027] The specific manifestations are: 1. Online dynamic telemetry and telesignal verification based on RCD files.

[0028] (1) The simulation test system parses the old SCD file to obtain the signal data of all substation devices.

[0029] (2) The new RCD file exported from the upgraded monitoring background is used as the point signal source. The simulation test system reads the telemetry data and telesignaling data in the RCD file, and automatically sends the telemetry signal and telesignaling signal to the data gateway (before and after the upgrade) in the order of the telemetry point number and telesignaling point number in the RCD file.

[0030] The time stamp for sending the telemetry and telesignaling point numbers is a custom time stamp, which is defined as follows in this embodiment: YY-MM-DD HH-LL-SS TTT.

[0031] Among them, Y represents year; M represents month; D represents day; H represents hour; the first L represents minute; S represents second; T represents millisecond; the second L is used to represent the value of telesignal (0 or 1), and SSTTT has a total of 6 digits representing the telesignal / telemetering point number.

[0032] Meanwhile, the transmitted values of the telemetry signals are incremented by an offset one by one. For example, if the initial transmitted value is 0 and the offset is 1, the uploaded value of the first telemetry is the initial value plus the offset, which is 0. The uploaded value of the second telemetry is the uploaded value of the first telemetry plus the offset, that is, the uploaded value of the second telemetry is 1. The uploaded value of the third telemetry is the uploaded value of the second telemetry plus the offset, that is, the uploaded value of the third telemetry is 2, and so on. The offset and the initial value can be set according to the actual situation.

[0033] (3) The data network shutdown device before the upgrade and the data network shutdown device after the upgrade are respectively subjected to black box testing, and their respective changed data are sent to the simulated master station, and the simulated master station generates a "simulated master station record file". Among them, the "simulated master station record file" contains information such as point number, data type, data value, time stamp, etc.

[0034] Specifically: The simulated master station receives the changed data uploaded by the data network shutdown device before the upgrade and generates a "simulated master station record file A". The simulated master station receives the changed data uploaded by the data network shutdown device after the upgrade and generates a "simulated master station record file B".

[0035] The process for the simulated master station to generate the "simulated master station record file A" is as follows: The data network shutdown device before the upgrade accesses the simulation test system through the 61850 protocol and accesses the simulated master station through the 104 protocol. The simulation test system triggers the changed data in the order of the point numbers of the telemetry and telecontrol signals in the RCD file. The data network shutdown device before the upgrade uploads the changed data to the simulated master station, and the simulated master station automatically records the received changed data of the telemetry and telecontrol signals. After all triggers are completed, the "simulated master station record file A" is obtained.

[0036] The process for the simulated master station to generate the "simulated master station record file B" is as follows: The data network shutdown device after the upgrade accesses the simulation test system through the 61850 protocol and accesses the simulated master station through the 104 protocol. The simulation test system triggers the changed data in the order of the point numbers of the telemetry and telecontrol signals in the RCD file. The data network shutdown device after the upgrade uploads the changed data to the simulated master station, and the simulated master station automatically records the received changed data of the telemetry and telecontrol signals. After all triggers are completed, the "simulated master station record file B" is obtained.

[0037] Through black box testing, it is detected whether each function of the data network shutdown device can be used normally.

[0038] (4) Compare the consistency of the "simulated master station record file A" and the "simulated master station record file B". If the "simulated master station record file A" and the "simulated master station record file B" are consistent, it indicates that the consistency check is correct, and it is considered that for the master station side, the forwarded telemetry and telecontrol signal information of the data network shutdown device remains unchanged after the upgrade; otherwise, the consistency check fails, and for the master station side, the forwarded telemetry and telecontrol signal information of the data network shutdown device changes after the upgrade.

[0039] During comparison, the consistency of the simulated master station receiving telemetry and telecontrol information is judged by comparing various information in the "simulated master station record file".

[0040] II. Online dynamic remote control verification based on RCD files.

[0041] (1) The simulation test system analyzes the old SCD file to obtain the signal data of all devices in the substation.

[0042] (2) Take the new RCD file exported from the upgraded monitoring background as the point-to-point signal source. The simulated master station reads the remote control data in the RCD file and automatically sends remote control messages to the data network shutdown devices before and after the upgrade according to the remote control sequence recorded in the RCD file.

[0043] (3) The data network shutdown device before the upgrade and the data network shutdown device after the upgrade are respectively subjected to black box testing. The remote control information is sent to the simulation test system respectively. The simulation test system generates a "remote control record file" containing remote control index reference, remote control value, remote control result, and failure reason information. The "remote control record file" contains remote control index reference, remote control value, remote control result, and failure reason information.

[0044] Specifically: The simulation test system generates a "remote control record file A" according to the remote control information sent by the data network shutdown device before the upgrade, and the simulation test system generates a "remote control record file B" according to the remote control information sent by the data network shutdown device after the upgrade.

[0045] Among them, the process of the simulation test system generating the "remote control record file A" is as follows: The process of the simulation test system generating the "remote control record file B" is as follows: (4) Compare the RCD file with the "remote control record file", mainly comparing the remote control index reference information. If the two are consistent, it means that the simulated master station or the data network shutdown device has not missed or sent multiple remote control points. Otherwise, it means that the simulated master station or the data network shutdown device has missed or sent multiple remote control points, and it is necessary to return to step (2) and the simulated master station resends the remote control message.

[0046] If the simulated master station or the data network shutdown device has not missed or sent multiple remote control points, compare the consistency of the "remote control record file A" and the "remote control record file B". If the "remote control record file A" and the "remote control record file B" are consistent, it means that the consistency verification is correct, and it is considered that for the master station side after the upgrade, the forwarded telemetry and telecontrol information of the data network shutdown device remains unchanged; otherwise, the consistency verification fails, and for the master station side after the upgrade, the forwarded telemetry and telecontrol information of the data network shutdown device has changed.

[0047] During comparison, the consistency of the telemetry and telecontrol information received by the simulated master station is judged by comparing the various pieces of information in the "remote control record file".

[0048] The data consistency verification method based on the RCD file provided in this embodiment, when upgrading the network gateway of the existing stations, uses automated means to verify the data consistency before and after the upgrade of the network gateway, without the need for cumbersome manual point-to-point operations, with high point-to-point efficiency and can effectively shorten the transformation verification cycle.

[0049] Embodiment 2: This embodiment provides a data consistency verification system based on the RCD file, which is used to execute the data consistency verification method based on the RCD file provided in Embodiment 1. When upgrading the network gateway of the existing stations, it uses automated means to verify the data consistency before and after the upgrade of the network gateway, without the need for cumbersome manual point-to-point operations, with high point-to-point efficiency and can effectively shorten the transformation verification cycle.

[0050] A data consistency verification system based on the RCD file includes: a simulation test system 1, a pre-upgrade data network gateway 2, a post-upgrade data network gateway 3, a simulated master station, and a multi-data source offline comparison module 6. The simulation test system is connected to the pre-upgrade data network gateway, the post-upgrade data network gateway, and the multi-data source offline comparison module. The simulated master station is connected to the pre-upgrade data network gateway, the post-upgrade data network gateway, and the multi-data source offline comparison module.

[0051] It should be noted that in this embodiment, in order to reflect before and after the upgrade, the pre-upgrade data network gateway is the data network gateway running with the pre-upgrade configuration file in backup, and the post-upgrade data network gateway is the data network gateway running with the post-upgrade configuration file.

[0052] The simulated master station includes a simulated master station A 4 and a simulated master station B 5. The simulated master station A is connected to the pre-upgrade front-end data network gateway, the simulation test system, the pre-upgrade data network gateway, and the multi-data source offline comparison module. The simulated master station B is connected to the post-upgrade data network gateway and the multi-data source offline comparison module.

[0053] The functions of each module in the data consistency verification system based on the RCD file are further described below.

[0054] The simulated master station A receives the changed data sent by the pre-upgrade data network gateway, generates a "simulated master station record file A", and at the same time has an automatic remote control function, can read the remote control data in the RCD file, and send the remote control data to the pre-upgrade data network gateway.

[0055] The simulated master station B receives the changed data sent by the upgraded data network shutdown device, generates the "Simulated Master Station Record File B", and at the same time has an automatic remote control function. It can read the remote control data in the RCD file and send the remote control data to the upgraded data network shutdown device.

[0056] The simulation test system can automatically send telemetry and telecontrol data, can read the telemetry and telecontrol data in the RCD file and send them to the data network shutdown devices before and after the upgrade, and at the same time can generate the "Remote Control Record File" according to the remote control requests of the data network shutdown devices before and after the upgrade.

[0057] The simulation test system takes into account real-time and massive real-time database systems, and can store secondary device models, substation device acquisition point information configurations, and automatic test tasks. The simulation test system can use protection devices, measurement and control devices of national simulation models in real-time and dynamically, and various types of devices for various actual operations of integrated protection and measurement and control, such as installation and safety automatic devices, such as normal operation, action, alarm, abnormal output, etc. It can not only complete the overall function and performance simulation tests of the substation automation system, such as massive data tests and network hierarchical tests; but also complete the real-time closed-loop simulation tests of various types of system equipment, such as equipment function and performance tests, real-time four-remote tests, protection event simulation and replay, protocol tests, and message parsing. It can simulate various actual operating conditions of substation equipment, generate corresponding real-time changed data and provide it to the system, and conduct tests based on the processing of the simulated real-time data stream by the system under test. It can simulate the total data flow of the whole station, such as simulating massive data to achieve the limit test of the system data processing capacity, including telecontrol avalanche test, telemetry change test, simulating the sending of a large number of accident position changes, simulating the sending of fault recording data, etc.; it can also conduct hierarchical tests on the network transmission layer, and conduct targeted tests according to the different characteristics of the physical layer, link layer, and application layer, and can accurately and comprehensively reflect the actual operating conditions of the system.

[0058] The multi-data source offline comparison module supports the comparison between various types of files, including the comparison between "Simulated Master Station Record Files", the comparison between "Remote Control Record Files", and the comparison between "RCD Files" and "Remote Control Record Files", and can output the verification results to help verify the accuracy of the data. For example: by comparing the "Simulated Master Station Record File A" and the "Simulated Master Station Record File B", it is judged whether the forwarded telemetry and telecontrol information of the data network shutdown device remains unchanged for the master station side after the upgrade; by comparing two different "Remote Control Record Files", it is judged whether the forwarded remote control information of the data network shutdown device remains unchanged for the master station side after the upgrade; by comparing the "RCD File" with the "Remote Control Record File", it is judged whether there are missing or multiple remote control signals sent by the data network shutdown device.

[0059] The data network gateway, namely the data communication network gateway, is a communication device used to realize the communication between the substation and the main station systems such as dispatching and production, and to provide data, model, graphics and file transmission services for the main station system to realize functions such as substation monitoring and control, information query and remote browsing.

[0060] According to the above data consistency verification system based on the RCD file, the process of verifying the data consistency of the data network gateway before and after the upgrade includes: I. Online dynamic verification of telemetry and telecontrol data based on the RCD file.

[0061] Its overall process is as Figure 2 shown, including: (1) The simulation test system analyzes the old SCD file to obtain the signal data of all station devices.

[0062] (2) Taking the RCD file exported from the new monitoring background as the point-to-point signal source, the simulation test system imports the RCD file generated by the new monitoring background, reads the telemetry and telecontrol data in the RCD file, and automatically sends the telemetry and telecontrol signals to the data network gateway in the order of the telemetry and telecontrol point numbers in the RCD file.

[0063] (3) The time stamp sent by the telecontrol / telemetry point is a custom time stamp, and the sent value of the telemetry adopts the method of increasing the offset one by one.

[0064] (4) The data network gateway conducts black box tests with the configuration file before the upgrade and the configuration file after the upgrade respectively. The simulation master station A receives the changed data sent by the data network gateway with the configuration file before the upgrade and generates the "simulation master station record file A", and the simulation master station B simultaneously receives the changed data sent by the data network gateway running with the configuration file after the upgrade and generates the "simulation master station record file B". Finally, the multi-data source offline comparison module automatically compares the consistency of the received information.

[0065] The process of the simulation master station A exporting the "simulation master station record file A": The data network gateway runs with the configuration file before the upgrade, accesses the simulation test system through the 61850 protocol for the lower layer and accesses the simulation master station A through the 104 protocol for the upper layer. The simulation test system triggers in the order of the telemetry and telecontrol point numbers in the RCD file and sends the changed data to the simulation master station A. The simulation master station A uses the "data point change record export function" to automatically record the received telemetry and telecontrol change data, and exports the "simulation master station record file A" after all triggers are completed.

[0066] Process for the simulated master station B to export the record file: The data network gateway runs with the upgraded configuration file, accesses the simulation test system through the IEC 61850 protocol at the lower layer, and accesses the simulated master station B through the IEC 104 protocol at the upper layer. The simulation test system triggers in the order of the telemetry and telecontrol point numbers in the RCD file and sends the changed data to the simulated master station B. The simulated master station B uses the "function for exporting the record of data point changes" to automatically record the received telemetry and telecontrol changed data and exports the "simulated master station record file B" after all triggers are completed.

[0067] (4)Use the multi-data-source offline comparison module to perform consistency verification on the "simulated master station record files" generated by the two simulated master stations.

[0068] Specifically: The multi-data-source offline comparison tool determines the consistency of the telemetry and telecontrol information received by the two simulated master stations by comparing various information in the "simulated master station record file" (such as point numbers, data types, data values, time stamps, etc.). If the consistency verification is correct, it is considered that for the master station side after the upgrade, the forwarded telemetry and telecontrol information of the data network gateway remains unchanged.

[0069] II. Online dynamic verification of telecontrol data based on the RCD file.

[0070] The overall process is as Figure 3 shown, including: (1)The simulation test system parses the old SCD file to obtain the signal data of all station devices and establishes an IEC 61850 connection with the data network gateway before and after the upgrade.

[0071] (2)The simulated master stations (including simulated master station A and simulated master station B) use the RCD file exported from the new monitoring background as the point signal source, import the RCD file generated by the new monitoring background, read the telecontrol data in the RCD file, and automatically send telecontrol messages to the data network gateway according to the telecontrol order.

[0072] (3)The data network gateway runs with the backup configuration file and the upgraded configuration file respectively, and uses the simulated master station to perform black box testing on it.

[0073] Generate the "telecontrol record file A": Before the upgrade, the data network gateway runs with the backup configuration file. After receiving the telecontrol message sent by the simulated master station A, it will send a telecontrol request to the simulation test system. After the simulation test system receives the telecontrol information, it returns the telecontrol result and the telecontrol-related telecontrol position, and saves the telecontrol result in the "telecontrol record file A". After the automatic telecontrol point alignment is completed, the simulation test system exports the "telecontrol record file A".

[0074] Generating "Remote Control Record File B": After the upgrade, the data network shutdown device runs with the upgraded configuration file. After receiving the remote control message sent by the simulated master station B, it will send a remote control request to the simulation test system. After the simulation test system receives the remote control information, it returns the remote control result and the remote signal position associated with the remote control, and saves the remote control result in "Remote Control Record File B". After the automatic remote control point matching is completed, the simulation test system exports "Remote Control Record File B".

[0075] Finally, the multi-data source offline comparison module automatically compares the consistency between "Remote Control Record File A" and "Remote Control Record File B".

[0076] (4) Using the multi-data source offline comparison module to perform consistency verification on the two "remote control record files". The multi-data source offline comparison module determines the consistency of the remote control information received by the simulation test system by comparing various information of the files (including remote control index reference, remote control value, remote control result, failure reason information). If the consistency verification is correct, it is considered that for the master station side after the upgrade, the remote control function of the data network shutdown device remains unchanged.

[0077] (5) Using the multi-data source offline comparison module to compare the RCD file with the remote control record file, and comparing the remote control index reference information to prevent the situation that the simulated master station or the data network shutdown device misses or sends multiple remote control points.

[0078] Based on the above, the technical problem to be solved by the data consistency verification system based on the RCD file provided in this embodiment is that the data consistency verification for the upgrade and transformation of the existing substation network shutdown device adopts the manual point matching method, which has problems such as cumbersome operation, low efficiency, high labor cost, and easy errors, affecting the normal operation of the substation.

[0079] It has the following beneficial effects: (1) Based on the RCD file, the standardized file is conducive to adapting to the RCD files of each manufacturer, so that the automatic point matching work can be carried out for the data network shutdown devices of each manufacturer.

[0080] (2) Based on the RCD file, using the automatic sending function of telemetry data and telecontrol data of the simulation test system, the telemetry data and telecontrol data are sent to the two data network shutdown devices before and after the upgrade. Then, the simulated master station generates the "simulated master station record file", and the multi-data source offline comparison module compares the two "simulated master station record files" to verify the consistency of the telemetry and telecontrol data of the network shutdown device before and after the upgrade, thereby improving the verification efficiency.

[0081] (3) Based on the RCD file, using the automatic remote control function of the simulated master station, remotely control the two data network shutdown devices before and after the upgrade respectively, and then the simulation test system generates a "remote control record file", and the multi-data source offline comparison module compares the two generated "remote control record files" to verify the consistency of the remote control data of the network shutdown device before and after the upgrade, so as to improve the verification efficiency.

[0082] (4) During the remote control verification, the comparison between the "RCD file" and the "remote control record file" is also carried out to avoid possible missing or multiple sending of remote control signals by the network shutdown device and help verify the accuracy of the data.

[0083] The above-described embodiments are only a preferred solution of the present invention, and do not impose any form of limitation on the present invention. There are other variations and modifications without exceeding the technical solutions recorded in the claims.
