The Transmission Line Optimization Programs -- TLOP and TLOPWT are intended to help the transmission line designer to evaluate the many different choices that he must make with regard to structure, conductor and right-of-way. The program combines a number of calculations, normally done separately, into a single program. In order to minimize the data input required, electrical and mechanical conductor data is available simply by entering the conductor's Aluminum Association name. Structures and foundation costs are estimated by means of algebraic equations rather than detailed structural analysis. Within specified constraints on electrical field, magnetic field, radio noise, audible noise, terrain, structure height, structure spacing, ground clearance and MVA load, the designer is free to consider the widest variety of design solutions in minimizing the total cost of the transmission line. The TLOP and TLOPWT programs are fully integrated, sharing the maximum possible amount of input data. Both programs calculate the total present worth of revenue required for the line's direct costs and cost of electrical losses over the life of the line. TLOP allows the user to specify the typical spacing of structures, and allows for rapid evaluation of different conductor types and sizes, and designer constraints. TLOPWT, which includes an optimal structure spotting algorithm developed by Bates Engineering, requires terrain data and detailed structure family data. It gives a more precise estimate of structure cost and spacing and allows for more realistic design as a function of terrain but requires considerably longer time to run and more input data.
