The reactive power supplier supplies reactive power in order to maintain the system voltage, as a result, the system increases the voltage stability and diminishes the power losses.
Recently, the growing construction of the underground transmission cable on the area of the great cities provokes the increasing of the line charging. In the light load case, the line charging provokes a elevation of the bus voltage.
In this paper the effect of the bus voltage to analysed in function of the line charging and the shunt reactor for 154kV substation using EMTP(electromagnetic Transient Pogram).
