  • TIMR : Time Interleaved Multi Rail

    Creator:
    Ruggeri, Thomas L.
    Abstract:
    This work presents a new energy saving technique for modern digital designs. We propose Time Interleaved Multi-Rail (TIMR) - a method for providing two dynamic supply rails to a circuit. This technique uses the first supply rail to mask the transition delay while changing the voltage of the second rail....

  • Theoretical influence of untransposed transmission line construction on system losses and voltage balance

    Creator:
    Chanakorn, Chavalit
    Abstract:
    The purpose of this thesis is to investigate the necessity of transposition in the construction of overhead transmission lines. Line currents, line voltages and line losses of both the transposed and untransposed lines were calculated and compared for two different voltage classes. The conventional method of symmetrical components was used...

  • Transmission line tower location by digital computer methods using a parabolic approximation

    Creator:
    Hotrabhavananda, Kajornsak
    Abstract:
    In this thesis, a digital computer method for locating transmission line towers is presented. The computer program selects the position of both angle and tangent type towers for a given ground profile. This selection will provide a minimum cost per foot of transmission line in terms of the average costs...

  • 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...

  • Determining The Impact of Photovoltaic Generation on Power Systems

    Creator:
    AL-Anazi, Falah
    Abstract:
    The National Conference of State Legislatures NCSL declares that 29 states have been active in adopting and increasing renewable portfolio standards. Present renewable portfolio standards require utilities to increase integration of renewable energy sources such as photovoltaic (PV). The increased penetration of PV systems is expected to destabilize the power...

  • A method of improving power system transient stability using controllable parameters

    Creator:
    Mittelstadt, William Andrew
    Abstract:
    Controllable parameters in a power system include generator terminal voltage, generator input power and network admittances. These parameters can be controlled to damp mechanical rotor oscillation in the generators and thereby improve system transient stability. Explicit equations are derived in this thesis for the control of these parameters to introduce...

  • Micro in-lab grid integration of a wave energy converter

    Creator:
    Okuda, Jeremy S.
    Abstract:
    Ocean wave energy has great potential to develop into a strong and reliable form of renewable energy. As the technology develops, more wave energy converters will be grid interconnected and the variable nature of the ocean will begin to influence the stability of the electrical grid system. There are many...

  • A novel linear generator for wave energy applications

    Creator:
    Ernst, Steven George
    Abstract:
    With the increasing effort to identify alternative methods of energy generation, extraction of ocean energy has gathered a large interest. Research and industry have begun considering wave energy as the next new alternative energy. The unique challenges of ocean energy requires a wave energy converter to be both robust and...

  • Evaluation of dynamically controlled resistive braking for the Pacific Northwest power system

    Creator:
    Raschio, Peter J.
    Abstract:
    Today's power systems are undergoing dynamic changes in their operation. The high cost of capital improvements that include new generation and transmission projects has prompted power system planners to look for other alternatives in dealing with increased loads and overall system growth. A dynamic braking resistor is a device that...
