Transposition of medium and long transmission lines
The transmission lines must be balanced electric circuits, theoretically, it must be an equivalent circuit that takes into account the uniform distribution of the parameters along the line. When it comes to transporting energy over long distances it is necessary to consider the effect of the capacitance, since each phase has a different capacitance causing each line to introduce an imbalance to the electrical system, for this reason, it is necessary to study the transposition of the cables. In the present work, several simulations of transmission lines with and without transposition are made, and the voltage unbalance that occurs as the line is longer has been verified. The simulations have been carried out under conditions of balanced load and fixed voltage in the arrival bar. Using the Sim Power Systems tool from Matlab, it was possible to check the behavior of the parameters of the line, depending on the geometric layout of the structure and its length. By applying this software, the objective is achieved by checking the stress unbalance problems suffered by a transmission line when transposition is not made.
