The problems associated with the flow of reactive power in transmission and distribution lines are well known. Several methods of var compensation have been applied in solving these problems. One of the modern devices employed in reactive power compensation is the three-phase solid-state var compensator (SSVC). The principal component of this device is a three-phase pulse-width-modulated voltage source inverter. A mathematical model of the inverter is derived and then used to examine the stability of the compensator in response to variations in circuit parameters.
