Accuracy of Voltage Unbalance Source Assessment in Three-Phase Three-Wire Electrical Networks

Optimal Determination Method of the Transposition Steps of An Extra-High Voltage Power Transmission Line

“…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.…”
