Abstract :
The power circuit of a general active power line conditioner
(APLC) is based on series and shunt power converters that
share a single dc link. In the present paper, a generic control
concept for these series and shunt converters is proposed. It is
based on the instantaneous real and imaginary power theory. In
fact, the resulting equipment deals with the Custom Power and
FACTS concepts. This equipment incorporates not only the compensation
functions at the fundamental frequency like a Unified
Power Flow Controller (UPFC), but also provides active harmonic
mitigation capabilities. For these reasons, the compensator
proposed here will be called the Universal Active Power Line
Conditioner (UPLC). Simulation and experimental results are
presented to confirm that the new approach has better performance
than those obtained by controllers based on traditional concepts
of active and reactive power.
