VSI BASED D-STATCOM

Distribution side Static Compensator (STATCOM) for VAR and Harmonic Compensation

A VSI based D-STATCOM is used to supply both reactive VAR and Harmonic current to the load, so the source current is sinusoidal and have Unity power factor(UPF).
A vector control method & SPWM scheme is used for closed loop operation and pulse generation,
which have 2 controllers.
1.Voltage controller- used to maintain constant DC link voltage.
2.current controller-
d-axis controller : supplies the harmonic current & draws little active current to meet the switching losses.
q-axis controller : supplies both harmonic & reactive current.
