Correlation analysis of weather factors and outage duration

摘要

The correlation analysis of weather factors and outage duration can provide reference for enterprises to make decisions in advance when weather changes, which guarantees stable operation of power grid system. Therefore, aiming at the correlation between weather factors and outage duration, this paper researches linear correlation and nonlinear correlation between them from Pearson correlation coefficient and distance correlation coefficient. Secondly, the gbdt algorithm model is used to measure the contribution ratio of different weather factors in the prediction model by establishing the prediction model between weather influencing factors and response variables, so as to obtain the correlation between different weather factors and outage duration. Finally, the experiment is carried out on a real data set. According to the analysis of the experimental results, the correlation between weather factors and outage duration is described.
