Multiple Regression Analysis between Weather Factor and Line Outage using Logit Model

로짓(Logit) 모델을 이용한 날씨요소와 송전선로 고장의 다중회귀분석

This paper investigates the effect of weather factors(such as winds, rain, snows, temperature, clouds and humidity) on transmission line outages. The result shows that weather variables have significant effects on the transmission line historical outages and the relationship between them is nonlinear. Multiple regression analysis using Logit model is proved to be appropriate in forecasting line failure rate in KEPCO systems. It could also provide system operators with useful informations about system operation and planing.
