| Zusammenfassung: | A system 10 for improving wind turbine generator 24 performance is disclosed. In one aspect a rotary power generation system is provided, including: a rotary power generator 24 for generating variable-frequency alternating currents; a negative sequence current regulator 50 that determines and uses frequency-dependent D-axis and Q-axis negative sequence gains based on an electrical frequency of the rotary power generator 24; and a system 58 for controlling voltage components for balancing the variable-frequency alternating currents generated by the rotary power generator (24) based on the D-axis and Q-axis negative sequence gains. |
