Description
Technical Field
The invention relates to an online monitoring and analyzing system of a relay protection and safety automatic device, in particular to a method, a device and a main station for correcting fault phase of a relay protection fault information system.
Background
With the continuous development of information technology and the gradual and deep application of a relay protection fault information master station system (called a 'information protection master station' for short), users put higher requirements on the aspects of service function, system safety, stability, access capability and the like of the system. In a modern power system, the electricity consumption of one area depends on a power supply provided by a transformer substation, one of the most important devices in the transformer substation is a relay protection device, and manufacturers of the relay protection devices in the transformer substation are different, when a fault occurs, some protections can accurately send the fault phase difference, some protections can send the correct fault phase difference firstly and then send a reset signal, and the reset signal can form interference, so that the fault phases sent at two ends of the substation are different. For double-end faults of a line, if the faults sent from the two ends of the substation are different, fault analysis of the main station end is affected, and further fault report data are inaccurate.
When the operation and maintenance personnel or experts of the information-guaranteeing main station find that the fault phase in the fault report is wrong, the fault report needs to be manually edited, and the wrong fault phase is modified into the correct fault phase. The fault phase in the fault report is manually modified in a manual mode, so that the efficiency is low, and the displayed data has certain time delay. In addition, when similar faults occur on the same line again, the fault phase in the fault report still needs to be manually modified in a manual mode.
Disclosure of Invention
The invention aims to provide a method for correcting a relay protection fault information system fault phase difference, which aims to solve the problem that fault report data of the conventional relay protection fault information system is inaccurate.
Meanwhile, the invention also aims to provide a device for correcting the relay protection fault information system fault phase and a relay protection fault information system master station, which use the method for correcting the relay protection fault information system fault phase.
In order to solve the problems, the method for automatically correcting the fault phase of the relay protection fault information system adopts the following technical scheme: a method for correcting fault phase information of relay protection fault information system includes comparing fault phase information sent from two sides of fault line, using the inconsistent part of fault phase information sent from two sides as interference information to correct fault phase information sent from one side containing interference information to be consistent with fault phase information of another side when fault phase information sent from two sides is inconsistent.
Has the advantages that: the method of the invention improves the method for generating fault report data of the fault phase of the existing relay protection fault information system, before the fault phase information of the two ends of the fault phase is uploaded to the main station, the inconsistent information of the two ends of the fault phase is preprocessed, the preprocessing takes the inconsistent part of the fault phase information sent on the two sides as the interference information, the fault phase information sent on one side containing the interference information is corrected to be consistent with the fault phase information of the other side, based on the characteristic of the existing relay protection, the preprocessing actually erases the reset signal of the relay protection device, the authenticity of the fault phase obtained by the main station cannot be influenced, and the fault phase information uploaded at the two ends of the fault phase obtained by the main station can be consistent, thereby solving the problem of inaccurate fault report data of the existing relay protection fault information system.
Furthermore, the comparison and correction of the fault phases sent on both sides of the fault line are performed periodically. The comparison and correction of the fault phases sent on the two sides of the fault line are carried out according to the period, so that the comparison and correction are more regular, and the automation is more convenient to realize.
Furthermore, the comparison and correction of the fault phases sent on both sides of the fault line are performed in a fixed period.
Further, the fixed period is 24 hours. The period is consistent with the period of the master station generating the fault report, and can be better matched with the work of the master station.
Further, the comparison of the fault phases sent on both sides of the faulty line is performed before (i.e., including no zero point) 23 o 'clock to 0 o' clock of the next day. If the correction program is executed at 20 o 'clock to 21 o' clock per day, the correction program can be executed before 21 o 'clock, but the fault report after 21 o' clock cannot be executed, so in order to expand the coverage of the correction program as much as possible, the correction program can be set between 23 o 'clock to the next 0 o' clock (not included) per day. Therefore, the fault phase information is corrected in the time period, and the accuracy of the corrected report data is improved.
Further, the correction record is stored while the phase difference information of the failure is corrected. The stored correction records can be checked by experts or maintenance personnel so as to avoid other problems caused by reporting data errors.
The invention relates to a device for correcting a fault phase of a relay protection fault information system, which adopts the following technical scheme: the device for correcting the relay protection fault information system fault phase comprises a memory and a processor, wherein the processor is used for executing program instructions in the memory so as to realize the method for correcting the relay protection fault information system fault phase.
The relay protection fault information system master station adopts the following technical scheme: the relay protection fault information system main station comprises the relay protection fault information system fault phase correcting device.

4. starting a new timing task to poll a fault packet table for thirty minutes to inquire a record of a fault phase to-be-automatically-corrected value being '1';
