“…In this formulation, the problems of EHV transmission lines were considered in isolation for the three most common modes: minimum, maximum, and operational modes of power transmission. Analytical expressions for determining the loss of active power in the power line contain components of idling and short-circuit losses [41][42][43][44][45][46][47][48][49][50][51][52][53][54][55][56]. The latter are directly and inversely proportional, respectively, to the square of the voltage on the bus terminals, which determines the possibility of choosing the optimal voltage level.…”

During the design of extra-high-voltage transmission lines, studies of the influence of asymmetry due to the phase difference of the parameters on its processes and the electrical network were performed. To compensate for this source of asymmetry for transmission lines longer than 100 km, a relatively simple technical means was proposed and implemented—phase transposition (change of the mutual location of phase wires in space). However, at the same time transposition causes additional capital costs in construction and reduces reliability during operation, so when designing a specific transmission line, extra-high-voltage is desirable to evaluate the effectiveness of the use of this measure in the real electricity network. Thus, under certain conditions, even for a transmission line 600 km in length, it was possible to perform either an incomplete transposition cycle, or abandon this measure altogether.
