Title: Study on the icing process of transmission lines and the local meteorological parameters
Abstract: Meteorology is an important factor to the icing of power system. The study on meteorology and icing was delayed for absence of the effective scene icing data. An On-line Monitoring System of Transmission Line Conductor Icing Based on GSM SMS was designed and produced, by which the local meteorology, such as temperature, humidity, wind speed, wind direction, rain and snow, air pressure etc., and the icing status, such as gravity of the iced conductor, the thickness of icing coating, the frequency of gallop etc. can be measured in time. The study on meteorology and icing was made based on the scene icing data. The results show that the formation and dropping of icing of transmission lines was related to the special meteorology, such as the temperature between −10°C and 0°C, the humidity large than 80%, the wind speed less than 10m/s, and the stationary wind direction, that reliability of forecasting icing is very poor according to a single meteorology, and the error is very large. The error is 248% when the temperature is used only to forecasting icing. The accuracy, error, failure of forecasting icing is 67%, 18% and 39% when some meteorology are used together. The accuracy, error, failure of forecasting icing is 86%, 13% and 3% when the fuzzy theory is used.
