Abstract

Methods for selecting a conductor configuration of an overhead power transmission line tension section between two dead-end towers when the conductor configuration includes at least two different types of conductors. Geographical profile information and overhead power transmission line preferences are used along with predetermined selection rules when selecting the appropriate conductor configuration. Some examples of overhead power transmission line preferences include electrical characteristics and conductor sag between towers, while examples of selection rules include conductor costs and conductor tension.

identifying at least one desired parameter of an overhead power transmission line tension section to be supported by at least two towers;

receiving geographic profile information that describes a geographic region to which the overhead power transmission line tension section it to be installed;

modeling the overhead power transmission line tension section according to the geographic profile information and the at least one identified desired parameter;

selecting a conductor configuration for the overhead power transmission line tension section based at least part on the overhead power transmission line tension section model and at least one computer-implemented selection rule, wherein the conductor configuration comprises at least a first conductor cable in series with at least a second conductor cable having at least one parameter that is different than at least one parameter of the first conductor cable;

installing the at least first conductor cable and the at least second conductor cable of the selected conductor configuration in series as the overhead power transmission line tension section supported by the at least two towers at an installation location.

2. The method of claim 1 , wherein identifying the at least one desired parameter of the overhead power transmission line tension section comprises receiving an overhead power transmission line input via a user interface of a conductor selection system, and wherein selecting the conductor configuration is automatically performed by the conductor selection system.

3. The method of claim 1 , wherein identifying the at least one desired parameter of the overhead power transmission line tension section is performed manually by a human.

4. The method of claim 1 , wherein the first and second conductors differ in at least one of a weight, a thermal expansion, a diameter, a reinforcing material, a conductive material, an electrical resistance, a tensile strength, an elasticity, or a cost.

5. The method of claim 1 , wherein the at least two towers include at least one tangent tower that supports the overhead power transmission line tension section between two dead-end towers.

6. The method of claim 1 , wherein the at least one desired parameter of the overhead power transmission line tension section comprises at least one of an overhead power transmission line tension section clearance, an overhead power transmission line tension section sag, an overhead power transmission line electrical characteristic, an overhead power transmission line tension section weight, and an overhead power transmission line tension section tension.

7. The method of claim 1 , wherein selecting the conductor configuration further comprises selecting the conductor configuration of the overhead power transmission line tension section based upon at least one of a conductor configuration cost, a conductor configuration electrical characteristic, or a conductor configuration force on at least one tower.

8. The method of claim 1 , further comprising receiving tower input identifying at least one of a tower height or a tower location.

9. A computer-implemented system that selects conductors for an overhead power transmission line, the system comprising:

a processor that identifies at least one desired parameter of an overhead power transmission line tension section to be supported by at least two towers, and receiving geographic profile information that describes a geographic region to which the overhead power transmission line tension section it to be installed, wherein the processor models the overhead power transmission line tension section according to the geographic profile information and the at least one identified desired parameter, and selects a conductor configuration for the overhead power transmission line tension section based at least part upon the overhead power transmission line tension section model and at least one selection rule, wherein the conductor configuration comprises at least a first conductor cable in series with at least a second conductor cable having at least one parameter that is different than at least one parameter of the first conductor.
