State grid mechanical external damage prediction method

Abstract

The invention discloses a state grid mechanical external damage prediction method, and relates to the field of machine learning, the method is used for carrying out mechanical external damage risk prediction on a power tower pole, a power transmission line and a power transmission channel of a state grid. The method comprises the following steps: acquiring historical information, forming completehistorical data, resampling the complete historical data, training a Catboost model, acquiring current information, forming complete current data, and performing mechanical external damage risk prediction by using the trained Catboost model. The method provided by the invention can predict the probability and risk level of mechanical external damage risks of the power tower pole, the power transmission line and the power transmission channel, and deploy countermeasures in advance.

Description

【Technical field】 [0001] The invention relates to the field of machine learning, in particular to a method for predicting mechanical failure of the national grid. 【Background technique】 [0002] With the development of the economy, infrastructure construction in various regions is in full swing. During engineering construction, various large-scale construction machinery, such as cranes and excavators, shuttle back and forth on the construction site, which brings considerable risks to nearby power towers and power transmission lines. The risk of damage caused by construction machinery to power towers and power transmission lines is called the risk of mechanical external damage. Due to the safety knowledge and safety awareness of a small number of construction workers, it is difficult to effectively control the safety distance between large-scale construction machinery and high-voltage lines, and accidents such as discharge and line collision are prone to occur, resulting in ...

AI Technical Summary

Problems solved by technology

Due to the safety knowledge and safety awareness of a small number of construction workers, it is difficult to effectively control the safety distance between large-scale construction machinery and high-voltage lines, and accidents such as discharge and line collision are very easy to occur, resulting in large-scale power outages

This not only caused personal injury to the perpetrators, caused losses to the power company, but also affected the power consumption of factories and residents around the construction site.

However, at present, the main countermeasures for the mechanical failure of the power towers and power transmission lines of the State Grid are still in strengthening protection and emergency response after problems occur. Early warning of the possibility of mechanical breakage in the channel
