  • The doubly-excited generator and its utilization in a variable-speed generating system

    Creator:
    Agha-Mirsalim, Mojtaba
    Abstract:
    The doubly-excited machine can be used as a variablespeed generator or as a variable-speed-drive motor. In this thesis the focus is on the aspects associated with generating electric power (real and reactive) from erratic energy resources such as water or wind. In such cases, the power input to the prime...

  • Voltage controller for a variable speed generation system

    Creator:
    Weigand, Claus H.
    Abstract:
    An important task of a Variable Speed Generation (VSG) system is the capability to maintain and control the terminal voltage at some desired value as determined by the reactive power dispatch strategy.The main objective is to design a sub-optimal fixed-parameter controller in the sense that constraints with respect to practical...

  • Supervisory control of a doubly-fed machine

    Creator:
    Werahera, Priya N.
    Abstract:
    An EMCON-D distributed process controller is evaluated for control and monitoring of an experimental doubly-fed machine system. A closed-loop control circuit is implemented to operate the doubly-fed machine with constant rotor current. A standard PID algorithm as well as an algorithm tailored to the doubly-fed machine are evaluated.
