Description

TECHNICAL FIELD

[0001] The application relates to a file synchronization sharing method of a relay protection and fault information management system and belongs to the technical field of safe and stable operation of a power grid. BACKGROUND

[0002] A transformer substation plays a role of a power transmission transfer station in a power system, primary equipment in the transformer substation is an important component of power transmission, when the primary equipment generates an exception or a fault, a fault recording device in the transformer substation is triggered, the fault recording device records voltage and current at the moment and generates a fault recording file which is saved in a fault recording file storage server and is called and analyzed by a relay protection and fault information system, currently, the fault recording file is called by using an SMB sharing protocol or an NFS sharing mode.

[0003] Since the NFS sharing protocol uses plaintext to transmit all information on a network and data is not supervised when the data is shared by using the SMB protocol, the two sharing modes have the following problems: the original fault recording file is easily damaged without protection and the fault recording file is easily leaked.

[0004] In addition, timeliness and accuracy of the existing fault recording file synchronization method need to be further improved. SUMMARY

[0005] The application aims to provide a file synchronization sharing method of a relay protection and fault information management system, so as to solve the problems that the existing fault recording file synchronization method easily causes the original fault recording file to be damaged without protection, easily causes the fault recording file to be leaked and has low timeliness and accuracy.

[0006] To achieve the above-mentioned purpose, the scheme of the application includes the following steps.

[0007] S1: a communication server downloads a fault recording file;

[0008] S2: the fault recording file on the communication server is transmitted and copied to a local workstation by using SCP and SFTP;

[0009] S3: the fault recording file copied in the step S2 is transmitted and copied to a local workstation of another workstation by using SCP and SFTP, so that the fault recording file is synchronized and shared.

[0010] The technical scheme of the application uses SCP or SFTP in necessary transmission and copying processes, realizes encrypted transmission and encrypted copying of the fault recording file and protects the fault recording file from being leaked and damaged.

[0011] Further, the S1 includes the following steps.

[0012] 1) the workstation of the main station of the relay protection and fault information system issues a recording wave file download command to the communication server;

[0013] 2) the communication server forwards the recording wave file download command to the substation of the relay protection and fault information system;

[0014] 3) the substation of the relay protection and fault information system issues a recording wave file download command to each protection device;

[0015] 4) each protection device sends the recording wave file generated by itself to the substation;

[0016] 5) the substation sends the recording wave file to the communication server of the main station;

[0017] 6) the communication server saves the recording wave file and sends a recording wave file download success notification to the workstation.

[0018] The above is the whole specific process of downloading the recording wave file by the communication server, and through the specific process, the recording wave file can be downloaded to the communication server, which is helpful to realize the synchronous sharing of the recording wave file.

[0019] Further, the transmission process of the communication server downloading the recording wave file adopts the 103 protocol or the 61850 protocol. The transmission process of the technical scheme given by the application can ensure the smooth data exchange between different devices by adopting the 103 protocol or the 61850 protocol.

[0020] Further, the S2 comprises:

[0021] 1) after the workstation receives the recording wave file download success notification, the IP address and the Chinese encoding format of all workstations and the communication server are obtained;

[0022] 2) it is judged whether the encoding formats of the workstation and the communication server are consistent, if the encoding is consistent, the recording wave file on the communication server is transmitted and copied to the local workstation by using SCP and SFTP; if the encoding is inconsistent, the encoding is converted and special character processing is performed, and then the recording wave file on the communication server is transmitted and copied to the local workstation by using SCP and SFTP.

[0023] Further, the S3 specifically comprises:

[0024] It is judged whether the encoding formats of the workstation in the S2 and other workstations are consistent, if the encoding is consistent, the recording wave file copied in the S2 step is transmitted and copied to the local workstation of other workstations by using SCP and SFTP; if the encoding is inconsistent, the encoding is converted and special character processing is performed, and then the recording wave file copied on the S2 step is copied to the local workstation of other workstations by using SCP and SFTP.

[0025] Furthermore, S3 also includes using Quartz task scheduling method to synchronously share the recording files.

[0026] The above solution uses SCP or SFTP to transfer files, and when there is a new copy of the recording file on one or several workstations, the recording file will also be copied to other workstations, so the recording file can be safely and synchronously shared.

[0027] Furthermore, the Quartz task scheduling method includes the following settings:

[0028] Install the Quartz application on each workstation and communication server;

[0029] Set the job to compare the number of recording files on the communication server and the workstation to see if they are consistent. If they are inconsistent, remotely copy the missing recording files from the communication server to the corresponding workstation via SCP or SFTP.

[0030] Through the Quartz task scheduling method, the number of recording files on each workstation and communication server can be checked regularly. When it is found that the recording files of a workstation are missing, the missing recording files can be remotely copied from the communication server to the corresponding workstation via SCP or SFTP in a timely manner, which can further ensure that the recording files are accurately and timely shared synchronously.
