Notice of RetractionStudy on the monitoring technology for overhead transmission line icing

A large number of energy will be transmitted from west China to the industrial center of east China with carrying out the power developing strategy including “Delivering Electricity from the West to the East”, “North-south Power Exchange”, “National-wide Interconnection”, and starting the construction of Uhv power transmission lines. High-voltage overhead transmission lines have to go through the complex atmospheric environment such as high altitude, rainy, ice, and pollution. These situations will influence the insulation performance of transmission lines, which leads to the power system collapse caused by high-voltage transmission line fault. The transmission lines icing is one of the main reason of line fault. The icing condition of transmission lines in China is serious, and the probability of ice damage accident is highest in the world which causes the huge economic losses of China. Therefore, researching icing monitoring technology for conductor of transmission line have important practical significance. First, this paper sets up the physical model of icing transmission line. Second, calculates the resistance, inductance and capacitance of the icing line. At last, analysises the influence of the actual parameters changes which caused by the icing transmission lines, finds out the most obvious parameter changes when the transmission line icing and takes this parameter as electric parameter of online monitoring.
