Description: This paper investigates the effects of Static Var
Compensator (SVC) on voltage stability of a power system. This
paper will discuss and demonstrate how SVC has successfully
been applied to power system for effectively regulating system
voltage. One of the major reasons for installing a SVC is to
improve dynamic voltage control and thus increase system load
ability. This paper presents modeling and simulation of SVC in
MATLAB/Simulink. In this paper A SVC is used to regulate
voltage in a power system. When system voltage is low the SVC
generates reactive power (SVC capacitive). When system
voltage is high it absorbs reactive power (SVC inductive). The
SVC is rated +100 Mvar capacitive and 50 Mvar inductive. The
SVC more effectively enhance the voltage stability and increase
transmission capacity in a power system.
