Factors Affecting Air Humidity of Shantou Station

Abstract

The relative high humidity affects the normal running condition of converter station in Shantou. This paper is to identify the factors which result in the high humidity inside station. Based on the SCADA data and the hand copy data provided by China Southern Power Grid, VAR model and VEC model of Multivariate Time Series Analysis method are used to analyze the relationship among humidity inside station, temperature out of station, temperature inside station, DC load and other factors.
