Enhancement of Power System Dynamics Using a Phase Imbalanced Series Compensation Scheme

The paper presents a new series capacitive compensation concept, which enhances power system dynamics. The idea behind the concept is a series capacitive compensation which provides balanced compensation at the power frequency while it results in phase imbalance at other frequency of oscillations. The compensation scheme is a combination of a single-phase thyristor controlled series capacitor (TCSC) and fixed series capacitors in series in one phase of the compensated transmission line and fixed capacitors on the other two phases.
