Abstract

In this paper, a new type of single Phase static compensator (STATCOM) for low rating used in customer side is proposed. This new STATCOM is constructed by cascading a full-bridge (H Bridge) voltage-source inverter (VSI’s) to the point of common coupling (PCC.) A so-called sinusoidal pulse width modulation (SPWM) unipolar voltage switching scheme is applied to control the switching devices of each VSI. A new control strategy is adopted for compensating the harmonics and reactive current required by the load. The proposed STATCOM has the advantage of a fewer number of VSI’s, the VSI’s being identical and extremely fast in response to reactive power change and the control strategy adopted shows a good response.

Keywords

Static compensator, voltage-source inverter, PCC, reactive power, harmonic current.
