Abstract
This dissertation presents voltage control methods to improve the voltage level of a Power system while minimizing losses. Newton Raphson method is used to calculate active and reactive power and tap changing transformer is used to minimize the reactive losses. Uncontrolled reactive power flow can give rise to excessive reactive power losses and voltage drops. The strategy of this project is to analyze and to get a mathematical model and physical knowledge about load tap changer transformer (LTC) by computer simulation .the model is then used to study the behavior of the Sudanese National Grid (SNG) in its simplified form
