Abstract:
Transmission lines and network as a veins of electrical power systems andaccording to its importance we should focus about its operation and its problems.
In this research the issue of “Drop Voltage” was studied at long transmission linesin Atbara-Portsudan transmission line ,which has many problems related to loss of voltage .
The problem was solved by using Static Var Compensator (SVC) station which going to be temporary solution for drop voltage and it is not care about future considerations of power demands increasing.
The simulation of the effect of adding (SVC) have been done by using NEPLAN Program, and the results were obtained(voltage regulation) before and after using (SVC).
The results were obtained before and after adding the SVC from the simulation program, theregulation before adding the SVC was 23.5 percentbut after adding the SVC it was reduced to 2.78 percent
