Description: This paper presents the Direct Power Control of
Three-Phase Matrix Converters (DPC-MC) operating as Unified
Power Flow Controllers (UPFC). Since matrix converters allow
direct AC/AC power conversion without intermediate energy
storage link, the resulting UPFC has reduced volume and cost,
together with higher reliability. Theoretical principles of DPCMC
method are established based on an UPFC model, together
with a new direct power control approach based on sliding mode
control techniques. As a result, active and reactive power can be
directly controlled by selection of an appropriate switching state
of matrix converter. This new direct power control approach
associated to matrix converters technology guarantees
decoupled active and reactive power control, zero error
tracking, fast response times and timely control actions.
Simulation results show good performance of the proposed
system. Platform: |
