  • Frequency-domain, parameter estimation for a brushless, doubly-fed machine

    Creator:
    Ramchandran, Ashok
    Abstract:
    A Brushless, Doubly Fed Machine (BDFM) attempts to combine the advantages of conventional induction and synchronous types of electrical machines by its unique architecture. The validation of BDFM designs in an actual test environment requires the estimation of the BDFM model parameters from actual experimentation. Accurate values for the parameters...

  • Analysis of brushless doubly-fed, stand-alone generator systems

    Creator:
    Gorti, Bhanuprasad V.
    Abstract:
    This thesis introduces a Brushless Doubly-Fed Machine (BDFM), stand-alone generator system. Development of a BDFM current-forced model, along with the analysis of air gap power distribution between the two stator windings and the rotor circuit, pave the way for the characterization and analysis of stand-alone generator systems. The main disadvantage...

  • A study of the effect of the rotor coil couplings of a synchronous machine on its predicted transient response

    Creator:
    Nehrir, Mohammad Hashem
    Abstract:
    The effect of the mutual inductances between the rotor coils of a synchronous machine on its defined reactances and predicted transients are investigated. Two linearized models of the machine are considered. One uses the Laplace-Transform approach, with minimum number of assumptions on the inter-coil couplings, in developing a model for...
