Intelligent power grid fault positioning method and device

Abstract

The invention discloses an intelligent power grid fault positioning method and device. The method and the device monitor the operation temperature of distribution lines of the intelligent power grid system in real time, determine the normal operating state or abnormal fault operating state, warn about the area where the fault occurred, automatically estimate the location of the high-risk distribution network rack prone to occur fault and make an early warning mark, transmit the information through a communication function to a power grid base station and push it to the power grid operation andmaintenance personnel, so that faults can be processed more timely, and the influence caused by faults on the operation of the power grid is reduced. Measures can be taken in time for potential safety hazards to reduce the occurrence of operational faults. The distribution lines of each remote area are monitored in real time, so that the fault points can be intelligently judged, positioned in time and alarm can be timely raised when the remote areas occur an emergency situation, such as damage and fault of the distribution lines, so as to improve the operation and maintenance efficiency of the power grid.

Description

technical field [0001] The present disclosure relates to the technical field of smart grids, in particular to a smart grid fault location method and device. Background technique [0002] Smart grid is regarded as the next generation power grid, which uses information to ensure the customized supply and monitoring of electricity. In a smart grid, the amount of electricity generated can be adjusted according to the real-time needs of users. This can not only ensure the satisfaction of user needs, but also avoid the waste of excess power. A notable feature of the smart grid is the large-scale deployment of various sensors and smart meters. Therefore, a large amount of data and information will be generated by measurement, sensing and monitoring. [0003] In order to improve the existing problems in the dispatching link of the smart grid system, it is necessary to improve the dispatching system of the smart grid. By intelligently monitoring the operation of the smart grid, th...

Problems solved by technology

[0003] In order to improve the existing problems in the dispatching link of the smart grid system, it is necessary to improve the dispatching system of the smart grid. By intelligently monitoring the operation of the smart grid, the operation data of each distribution line is comprehensively analyzed to determine the next period of operation of the equipment. As a result, timely measures can be taken to deal with potential safety hazards to reduce the occurrence of operational failures. Power grid operation and maintenance personnel cannot perform real-time care on the distribution lines in each remote area. When the distribution lines in these remote areas are damaged, O&M personnel are often unable to detect emergencies such as faults in time, and even when an accident occurs on a power distribution line, they cannot locate the fault point in time and determine rescue measures. The long fault processing time cannot achieve the effect of improving the operation efficiency of the power grid

Therefore, it is necessary to use the sensor network to monitor, judge and locate the fault location. Since various sensor networks generate a large amount of data in the communication of the smart grid, the operating temperature of the power distribution line is detected to determine the operating state, and the abnormal temperature is displayed. Through the communication function, the It is unreasonable to manually monitor and judge the information transmitted to the power grid base station of the dispatching center. Therefore, it is particularly necessary to realize automatic fault location
