Minimization of the cost of an electric transmission line system

This paper presents a method for determining the design parameters for an electric transmission line system. A mathematical model is formulated using regression analysis to relate system costs and requirements to the system design parameters. In general, this mathematical model is both nonlinear and nonconvex. Solutions obtained for a specific problem using a nonlinear programming computer code are presented. Although the results are applicable only to this specific problem, the method of analysis is applicable to the general transmission line design problem.
