  • Passively controlled variable-speed generator system

    Creator:
    Bathon, Tobias Siegfried
    Abstract:
    This thesis presents both an analysis and simulations of a passively controlled variable-speed generator system, which can be applied for renewable energy sources such as wind turbines. Parallel connected passive/external resistors and inductors are connected to the slip rings of a wound rotor induction machine to provide an acceptable speed...

  • Development and Experimental Hardware Validation of Novel Variable Speed Hydropower Control Schemes for Emerging Applications and Water Resource Paradigms

    Creator:
    Starrett, Michael A.
    Abstract:
    Recent opportunities for new hydropower generation in the United States have often been in non-powered dams and run-of-river type flows occurring in low-impact natural areas and unregulated conduits. At the same time, a changing water resource paradigm is challenging some existing generation in drought stricken areas where supply reservoirs behind...

  • Dynamic control of brushless doubly-fed machines

    Creator:
    Zhou, Dongsheng, 1964-
    Abstract:
    This thesis presents the development of dynamic control strategies for the brushless doubly-fed machine (BDFM). A simple open-loop scalar controller is first investigated and its response is found to be oscillatory. Using the speed feedback signal, an improved closed loop scalar control algorithm is designed. Steady state performance is controlled...

  • A novel control design for a wave energy converter

    Creator:
    Schacher, Alphonse A.
    Abstract:
    Ocean wave energy is rapidly becoming a field of great interest in the world of renewable energy. Significant advancements in design and technology are being made to make wave energy a viable alternative for our growing energy demands. The two major hurdles for ocean wave energy to make a significant...

  • Computerised dynamic control of an ac dynamometer

    Creator:
    Rodrigues, Terence Keith
    Abstract:
    The Motor Systems Resource Facility (MSRF) at Oregon State University presently conducts a variety of steady state tests on Motors and Generators, with ratings of upto 300Hp.(225kW), using a dynamometer. The dynamometer consists of an induction motor fed by a power electronic converter. A control computer uses a serial link,...

  • Digital stabilizer for brushless doubly-fed machine

    Creator:
    Krishnan, Sheela
    Abstract:
    The exceptional feature of the brushless doubly-fed machine is the lack of need for frequent replacement of brushes. The inherent instability of this machine has to be overcome for its application in adjustable speed drives and variable speed generation systems. Specific objectives were: to study the characteristics of the machine...

  • Characterization studies and industrial control development for the brushless doubly-fed machine

    Creator:
    Koch, Brian
    Abstract:
    This thesis presents the development of a supervisory controller for a pre-commercial Brushless Doubly-Fed Machine (BDFM) drive system. In addition, characterizations of new diecast rotors for the BDFM are presented. Using the characterization results from the new rotors, a control scheme was developed to allow a BDFM to be packaged...
