  • sensorless variable Speed controller for existing Fixed Speed wind power generator with unity power factor operation
    IEEE Transactions on Industrial Electronics, 2003
    Co-Authors: G Poddar, Antony Joseph, A K Unnikrishnan
    Abstract:

    A variable-Speed controller, for an existing 225 kW Fixed-Speed wind power generator, is presented in this paper. A sensorless direct torque control algorithm-based controller is proposed for the squirrel-cage induction generator. Generator torque reference is derived based on sensorless maximum power tracking mode algorithm, up to the base Speed of the generator. A three-phase front-end converter is used here to deliver the generated power to the grid with unity-power-factor operation at all wind Speeds. This algorithm is based on direct active and reactive power control. The experimental waveforms from the actual installation site are presented in this paper with a comparison of the existing Fixed-Speed System. An interpretation of the results is also presented here.

  • a control strategy for direct drive permanent magnet wind power generator using back to back pwm converter
    International Conference on Electrical Machines and Systems, 2008
    Co-Authors: Keyuan Huang, Shoudao Huang, Feng She, Baimin Luo, Luoqiang Cai
    Abstract:

    Since variable-Speed generation has a higher energy capturing and converting efficiency than the Fixed-Speed System, new proposals for wind power System utilize variable-Speed generators are introduced, among which permanent-magnet synchronous generator(PMSG) is an attractive choice. This paper describes a sensorless vector control strategy for a direct-driven PMSG, which is connected to the power network through a fully controlled back-to-back PWM converter. The generator side converter is controlled to obtain maximum power from the incident wind and the grid-side inverter is to maintain DC-link voltage constant and regulate the power factor of the windmill. An experimental prototype, which represents a 3.7 kW variable Speed generation System, is carried out to verify the control method, and experimental results are given to illustrate the performance of the System.
