Solution Methods of Overhead Transmission Line Mechanics

Varga L., Ilenin S., Chladný V.

Electrical Power Quality and Utilisation. Journal

2006

Vol. 12, nr 1

17-20

Paper is focused to mechanics calculation of overhead transmission lines. In first part of this paper is presented mathematical model for complex solution of overhead line mechanics in a plan. Non-level overhead line can be considered. The second part of paper deals with a solution method of the mechanics of overhead line conductors in three-dimensional space in non- level span. This method enables to define three-dimensional location, vector of mechanics stress of suspended line in optional point of line under combined load caused by the ice and the wind of optional direction.

This paper deals with problems of reactors utilization on overhead transmission lines in order to balance reactive power. This compensation is necessary in case when power transmission is lower then natural capacity or there are no load condition. Rated power of reactors depends on natural capacity and length of the line.
