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.}, title = {Doubly fed induction generator using back-to-back PWM converters and its application to variable-speed wind-energy generation}, journal = {IEE Proceedings - Electric Power Applications}, issue = {3}, volume = {143}, year = {1996}, month = {May}, pages = {231-241(10)}, publisher ={}, copyright = {© IEE}, url = {https://digital-library.theiet.org/;jsessionid=nw5ds3a02pci.x-iet-live-01content/journals/10.1049/ip-epa_19960288} }
