Abstract

Abstract: Because of differences of geographical locations and weather conditions, a series of static and dynamic problems exist in the transmission line system. Determining space curve of overhead transmission line is basic prerequisite for researching dynamic problems of iced transmission line. After review of two existing calculation methods, a new unified method for calculating transmission line space curve is proposed. Taken an existing overhead transmission line as example, the space curves under different ice thicknesses and elevation angles are calculated by both former and proposed methods. Calculation results show that proposed method yields more accurate and practical results.

Key words: overhead transmission line, icing, space curve, catenary curve method, parabolic curve method
