Optimal allocation of electrical line supports

Abstract EN

The line supports are intended to suspend conductors and ground wires by means of insulators.

They ensure the necessary clearances between conductors and ground as well as clearances between conductors themselves.

Optimal allocation of line supports on the profile is of great importance for economic design of an overhead transmission lines.

This paper deals with preparation of sag template for optimal allocation of line supports.

The use of a sag template is essential to allocate the position and height of the supports correctly on the profile.

To fulfil this aim, computer algorithm and programme is developed.The main programme STDLS and its subsidiary subroutines are constructed for calculating and drawing the four curves (hot curve, cold curve, ground clearance curve and support foot curve) of the sag template.

The elaborated programmes are written in FORTRAN- 90 and adopted for personal computer
