Control system design of UPFC for power system damping enhancement taking into account rating of converter during oscillation
The unified power flow controller (UPFC) has the possibility to damp power system oscillations more effectively than power electronics applied devices such as SVG and TCSC. In this paper, a control system design of a UPFC for power system damping enhancement based on eigenvalue control method was proposed. As a result, it was made clear that the best design method is to determine steady-state value of UPFC control variables and control parameters of UPFC such as gains and time constants simultaneously because controllability of UPFC depends on the steady-state values of UPFC and the power flow condition. A UPFC control system, taking into account the ratings of power converters, is proposed. The effectiveness of the proposed control is verified by the digital time simulation.
