Abstract

The work presented in this paper is conducted over the Ferranti effect (line capacitive effect). Ferranti effects are well known in the field of power transmission over long distances at relatively low frequencies (Ibrahim 2005). The voltage at the receiving end can become the twice of voltage at sending end (usually in the case of very long transmission lines) (Walling 2002). It is potentially very destructive for network equipments and especially for Insulators of lines and electric cables, so it is very necessary to seek a solution to eliminate this effect in our network. To validate this study, we conducted several tests of MATLAB simulations on the Algerian network _ADRAR (using the MATLAB to give the locus of sending end voltage with line length which shows that receiving end voltage is greater than sending end voltage) and specifically electrical transmission lines (line ADRAR_TIMIMOUNE 192Km and line ADRAR_IN SALAH 409Km) with and without mobile self, knowing that This network is powered by a Gas Turbine plants of Adrar and In Salah, interconnected through a 220Kv network spreading from In Salah to Timimoun via Aoulef and Adrar. Finally, this simulation study refines the voltage setting in the grid. It highlights the advantage of using the mobile self 220Kv for stabilizing the voltage at the end of high voltage lines.
