By providing dynamic reactive power, SVC can be used for the purpose of regulating the system voltage,compensating the voltage at a reasonable level, improving the power flow capacity of the transmission line, enhancing the damping of the low frequency oscillation as well as inhibiting the sub-synchronous oscillation. Furthermore, SVC is also capable of inhibiting the variation of busbar voltage caused by the fluctuating load, which is favorable for the recovery of transient voltage and the improvement of stabilization of the system voltage. For industrial users, it can effectively control...
