| Abstract |
This paper presents a system that provides
photovoltaic generation as well as the functions of a unified power
quality conditioner. The system can be controlled for current
harmonics and reactive power compensation simultaneously by
using a converter operating as active shunt filter. The other
converter is used as active series filter and it compensates voltage
harmonics or voltage sags and swells. Using only an inverter in
photovoltaic energy conversion process, the system presents
increased efficiency when compared to the conventional systems.
The synchronous reference frame method is used to control the
three-phase converters. Simulation results demonstrate the good
performance of the proposed configuration. Experimental results
corresponding to the operation of the series filter as voltage sag
compensator are presented. |
