基于灰关联分析微气象因素和导线温度对输电线路导线覆冰的影响
Influences of Meteorological Conditions and Conductor Temperature on Icing oi'Transmission Line Based on Grey Relational Analysis
摘要
Abstract
Icing on transmission line is relevant to weather condition and conductor temperature. At present, thecorrelation analysis of the weather parameters and wire icing is not comprehensive and systematic, and in somestudies the impact of conductor temperature on transmission line has not been considered, therefore the mainfactors influencing wire icing have not yet been determined. This paper collects the monitoring data of icing fromthe 220 kV Tongli power lines and 220 kV Jiyangerhui power lines, analyzes the relation among transmissionline icing, conductor temperature and local meteorological conditions, such as ambient temperature, relativehumidity, wind speed, etc. by making use of grey relational analysis method, and achieves the correlationdegrees between icing and these four factors respectively to determine the key factor influencing wire icing on thetwo transmission lines. Results show that the correlation analysis result of the 220 kV Tongli power lines isconsistent with the one of 220 kV Jiyangerhui power lines, and the correlation degree between transmission lineicing and each influencing factor is similar one another. The importance sequence of the four factors influencingtransmission line icing is ambient windspeed > conductor temperature > ambient temperature > ambient relativehumidity, which indicates that the ambient windspeed is the key factor influencing transmission line icing.关键词
