Abstract Icing of transmission line and insulator threats the reliability of electric power system. Real-time Surveying of environment parameters is the key for icing mechanism research. Beginning with the two-phrase flow field, this paper analyzed the collision and freezing characteristics of water droplets, based on which, the icing rates of rotating conductors with different diameters were investigated, and the results helped confirming the method in which five rotating conductors can be used as icing objects for predicting environment parameters. With the help of differential evolution algorithm (DE), a predictive model for environment parameters based on modified DE was established, which has a good degree of accuracy lower than 10%. The verification tests were conducted at the Xuefeng Mountain icing base, decentralized rotating conductors were used to capture the icing data of a period of 6.7 h, the devices had a good working condition and the data were inputted into the predictive model. The predicted parameters including the wind speed, environment temperature, middle value diameter of water droplet and liquid water contain of air have errors lower than 7% which confirms the validity of the predictive model.

Key words： Decentralized rotating conductor icing environment parameters predictive model
