  • Design procedure for brushless doubly-fed machine used as a limited speed-range pump drive

    Creator:
    Alajmi, Abdulhadi M.
    Abstract:
    The continuing desire of industry to further improve process efficiency, through tighter control and energy conservation, has prompted users to pay closer attention to Adjustable Speed Drives (ASDs). The conventional ASDs consist of induction or synchronous motors controlled by power electronic controllers through the adjustment of supply frequency and line...

  • Analysis and design of the brushless doubly-fed machine

    Creator:
    Rochelle, Patrick R.
    Abstract:
    Use of conventional induction machines (IM) in adjustable speed drives (ASD) has increased in recent years. Electronic power processing has facilitated this increased use. The IM is an inexpensive and robust machine, but when used as part of an ASD, the cost of the system increases due to the inclusion...

  • Development of a variable-speed, doubly-fed wind power generation system

    Creator:
    Brune, Christopher S.
    Abstract:
    Generation of electricity from the wind is becoming increasing popular as an environmentally responsible resource. Current methods for generating electricity from the wind involve the use of fixed-speed generators. However, the use of variable-speed generators increases the amount of energy that can be extracted from the wind. Most variable-speed technologies...
