Abstract:

Static synchronous compensator (STATCOM) is a shunt connected FACTS controller which can improve the stability of the system. It provides sufficient damping during disturbance in the power system. This paper deals with an adaptive approach for power oscillation damping controller using STATCOM. It uses space vector pulse width modulation (SVPWM) for generating gate pulses required for the operation of the STATCOM. Output voltage of STATCOM depends on the gate pulses given to it. Among different pulse width modulation techniques, SVPWM technique is implemented as it is easy to achieve digital realization and dc bus utilization. SVPWM is controlled by proportional-integral (PI) controller whose output is given to it. A phase locked loop (PLL) is used to synchronize the grid voltage with ac output current of STATCOM. This method is effective in damping oscillations in the power system. A simulink model for this is created using MATLAB version R2015a. The simulation and experimental results are used to verify the effectivity of the proposed method to provide power oscillation damping.
