Problems solved by technology

However, the current maintenance work of power transmission equipment does not judge the actual operation status of the equipment, but conducts regular maintenance on the equipment in full accordance with the requirements of relevant regulations.
When encountering irresistible weather factors such as thunderstorms and high temperatures, maintenance must be stopped in consideration of personal safety, which not only causes the maintenance tasks of power transmission equipment to be unable to be completed on time, but also leads to a huge waste of manpower, financial and material resources, and also makes the health of the equipment unable to be guaranteed. , the reliability of power transmission is threatened

Abstract

The invention relates to the technical field of power transmission and distribution, and discloses a logistic regression-based power grid maintenance index calculation method and system, which are used for realizing calculation of a power grid maintenance index based on meteorological elements and providing a guarantee for reasonable arrangement of power grid maintenance. The method comprises thesteps of obtaining basic information of a to-be-overhauled power transmission line, establishing a basic database, and establishing a weather database of precipitation day by day in an area where theto-be-overhauled power transmission line is located; predicting the daily maximum temperature and relative humidity of the area where the power transmission line to be overhauled is located and the daily precipitation of seven days in the future by adopting a numerical mode; carrying out grid division on the region where the power transmission line to be overhauled is located according to latitudeand longitude, and corresponding to the numerical mode result; defining a high-temperature index, a rainfall index and an icing index, calculating a power grid maintenance probability according to the high-temperature index, the rainfall index and the icing index, determining the power grid maintenance index according to the power grid maintenance probability, and judging whether maintenance is needed according to the power grid maintenance index.

Description

technical field [0001] The invention relates to the technical field of power transmission and distribution, in particular to a method and system for calculating a grid maintenance index based on logistic regression. Background technique [0002] The distribution of transmission lines is directly affected by natural environments such as strong winds, heavy rain, freezing rain and snow, lightning strikes, and heavy fog. At the same time, geological disasters such as landslides and mud-rock flows caused by heavy rainfall also cause harm to the safe and stable operation of the power grid. Therefore, the condition-based maintenance of transmission lines becomes more and more important. However, the current maintenance work of power transmission equipment does not judge the actual operation status of the equipment, but conducts regular maintenance on the equipment in full accordance with the requirements of relevant regulations. In the event of irresistible weather factors such a...
