Problems solved by technology

[0002] The focus of smart grid intelligence lies in the power supply stage. Many researchers in this field are concentrating on how to supply power in the power supply stage. Therefore, the research on the power supply stage is becoming more and more mature, but the research on the fault monitoring process has not yet reached the mature stage. The existing fault monitoring process is attached to the existing circuit system, adding some current or voltage detection equipment, and then performing fault location based on the obtained voltage or current data
However, due to cost issues, it is impossible to install current or voltage detection equipment for each branch line of the power grid, and the current or voltage detection equipment is also easily damaged, and the problem of inaccurate fault location is prone to occur

Abstract

The invention discloses an intelligent power grid fault positioning method and device. The method comprises the following steps: obtaining repair request information of a user; processing the repair request information of the user to obtain a regional fault value and a fault threshold value; judging whether the regional fault value is greater than or equal to a fault threshold to obtain a first judgment result; when the first judgment result is yes, obtaining regional image information; the regional image information comprises a plurality of pieces of high-risk point image information; the smart grid power supply area to which the area image information belongs is consistent with the smart grid power supply area to which the user repair request information belongs; performing classification identification processing on the regional image information to obtain risk position information; the risk position information comprises a plurality of pieces of risk point information; the risk position information is used for indicating the positioning of the fault of the smart grid. Therefore, accurate fault positioning of the smart power grid is realized, the fault efficiency is improved, and the maintenance cost of the power grid is reduced.
