A vector-control scheme for the supply-side PWM converter results in independent control of active and reactive power drawn from the supply, while ensuring sinusoidal supply currents. Vector control of the rotor-connected converter provides for wide speed-range operation; the vector scheme is embedded in control loops which enable optimal speed tracking for maximum energy capture from the wind. An experimental rig, which represents a 7.5 kW variable speed wind-energy generation system is described, and experimental results are given that illustrate the excellent performance characteristics of the system. The paper considers a grid-connected system; a further paper will describe a stand-alone system. %@ 1350-2352 %T Doubly fed induction generator using back-to-back PWM converters and its application to variable-speed wind-energy generation %B IEE Proceedings - Electric Power Applications %D May 1996 %V 143 %N 3 %P 231-241 %I %U https://digital-library.theiet.org/;jsessionid=3ua5hfsom986i.x-iet-live-01content/journals/10.1049/ip-epa_19960288 %G EN
