A calculation program for choosing the rational power supply voltage for designing city, rural and industrial networks has been developed. The offered technique of assessment of discounted costs of construction of power supply systems for various voltages substantially reduces the designing expenses and decreases the execution time. On the basis of the investigations carried out by elements of the discounted cost of power supply system is proposed in the form of a continuous function, depending on the transmission power. For right choice of the voltage required calculations on three strains, which increases the cost of the final cost of the project. During the use of the program, only Microsoft Excel user tables are available for the designer, which enable fast correction of electric power costs at various voltage levels, the number of hours of greatest loads, discount norm, types of equipment used for each separate voltage value.
