Distribution network maintenance method and device based on discrete data

Abstract

The invention discloses a distribution network maintenance method and device based on discrete data, and the method comprises the steps: obtaining a large amount of detection data related to similar equipment when the equipment is determined to have a fault, and enabling the similar equipment to be the same as the fault equipment; calculating a fault correlation value between the mass detection data and the fault equipment; searching a plurality of historical maintenance schemes about the similar equipment based on the fault association value; and screening a target maintenance scheme from the plurality of historical maintenance schemes, and providing maintenance guidance and prompt for maintenance personnel. According to the method, the adaptive historical maintenance scheme can be searched from various discrete maintenance data, and the historical maintenance scheme is utilized to guide and prompt the maintenance personnel, so that the maintenance time can be effectively shortened, and the maintenance efficiency and the success rate can be improved.

Description

technical field [0001] The invention relates to the technical field of maintenance of power grid equipment, in particular to a distribution network maintenance method and device based on discrete data. Background technique [0002] With the gradual increase in power demand, it is an important measure to ensure the safe and stable operation of distribution network equipment. Therefore, it is necessary to check, maintain and repair each distribution network equipment at all times, and in the case of improving the economic benefits of the power grid enterprise itself, it can also ensure the reliability of the power supply of the distribution network to the greatest extent. [0003] In order to improve the maintenance efficiency, the current common maintenance method is to detect the real-time operating status of the distribution network equipment through the monitoring system, determine the fault type based on the operating status of the distribution network equipment, and fina...

Problems solved by technology

[0004] However, the currently commonly used methods have the following technical problems: In order to carry out targeted maintenance and treatment, after the maintenance personnel arrive at the distribution network equipment, they will conduct a second inspection in the field, so as to perform corresponding maintenance according to the inspection results. This operation will increase the maintenance time and reduce the maintenance efficiency; moreover, each maintenance personnel has different maintenance processing capabilities, so it is difficult to ensure that the distribution network equipment can be repaired every time, and it is easy to cause secondary failures of the distribution network equipment, and then As a result, the power supply of the power grid is unstable, and it needs to be repaired again, which increases the maintenance cost
