| Abstract |
This paper proposes modified dual vector
current control (DVCC) for the wind turbine application.
As in case of conventional DVCC, it fulfills requirements for
average unity power factor with suppressed oscillations in
active power flow. However, uncontrolled increase in
converter output current under unbalanced grid voltage
conditions is prevented through imposing limit in its
magnitude. Multilevel back-to-back converter is used in
order to achieve full control of the turbine, as well as better
power quality and lower torque and grid current oscillation. |
