  • Reactive power optimization using adaptive excitation control of synchronous power

    Creator:
    Al Hamrani, Majed M.
    Abstract:
    Synchronous machines provide a practical way to control reactive power consumption of a plant. One of the main advantages of using synchronous motors in a plant is their ability to generate reactive power for plant loads. A new control scheme for synchronous motor excitation systems is developed to automate reactive...

  • Development of biomimetic control strategies for the optimal use of renewable sources and energy storage systems

    Creator:
    Hapke, Hannes Max
    Abstract:
    In the year 2007, the worldwide energy consumption accumulated to a total of 16.5 billion MWh. While the resources of conventional energy production cause environmental damage, renewable energy sources like solar or wind power offer a solution to substitute for coal or nuclear generated power. Countries like Denmark and Spain...

  • Detection of incipient rotor bar faults and air-gap asymmetries in squirrel-cage motors using stator current monitoring

    Creator:
    Al Tuaimi, Hamad A.
    Abstract:
    Preventative motor fault detection is of prime importance for modern plant management. During research into rotor faults, performed at the Motor Systems Resource Facility (MSRF), an optimized rotor fault detection and classification method was proposed. In critical process applications, the suggested method would provide the foundation for continually monitoring a...

  • Hybrid electric vehicle dc-bus converter harmonics

    Creator:
    Mills-Price, Michael A.
    Abstract:
    As more advanced hybrid electric vehicles begin emerging onto the commercial market, design algorithms for their control become increasingly more complicated. One major hurdle for designers is the mitigation and control of the created high frequency harmonics caused from switching the dc voltage into an ac voltage by use of...

  • Advanced propulsion systems for linear motion with high performance requirements

    Creator:
    Zhou, Xiaolin
    Abstract:
    Traditionally linear actuator applications are addressed by the use of hydraulic systems. The high maintenance cost and poor reliability will always be the most critical problem in the real applications. Benefited from both the high mechanical advantage of the roll screw and the simple structure of the switched reluctance motor,...

  • Hybrid electric vehicle active rectifier performance analysis

    Creator:
    Amon, Ean A.
    Abstract:
    In advanced hybrid electric vehicle development, performance and dependability are essential considerations in the design process. High efficiency is crucial in a successful design and fault tolerance is necessary to provide limp-home capability under faulted operating conditions. The reduction of electromagnetic interference is mandatory to reduce interference in communications and...

  • Electromagnetic analysis of energy system devices

    Creator:
    Li, Yan
    Abstract:
    Many new applications of energy system devices have been developed to save energy, improve the controllability and stability of industrial processes, and reduce the weight, volume and cost of consumer devices. Due to the novelty of these devices, traditional empirical methods and lumped-parameter circuit theory methods are not sufficient for...

  • Novel design and implementation of a permanent magnet linear tubular generator for ocean wave energy conversion

    Creator:
    Prudell, Joseph H.
    Abstract:
    The world’s energy consumption is growing at an alarming rate and the need for renewable energy is apparent now more than ever. Estimates have shown that optimization of the extraction of energy from the ocean could significantly aid the world’s quest for sustainable and affordable energy services for all. From...

  • Scaled modeling and simulation of ocean wave linear generator buoy systems

    Creator:
    Gore, Ganesh P.
    Abstract:
    Accurate scaled modeling and simulation are critical to advancing ocean wave linear generator buoys. A 100th scaled model of ocean wave generator buoy systems is analyzed by solving the Navier-Stokes equations. These equations are numerically solved using Computational Fluid Dynamics (CFD) by implementing the front capturing method. In this thesis,...

  • Evaluation of the performance of a taut-moored dual-body direct-drive waveenergy converter through numerical modeling and physical testing

    Creator:
    Elwood, David E.
    Abstract:
    With energy prices rising and increasing concern about the influence of fossil fuels on climate change, wave energy systems are on the verge of commercial implementation. These first generation wave energy converters utilize either pneumatics or hydraulics to convert the mechanical energy of waves into electricity. For the last several...
