An evaluation of the cubic autotape under dynamic conditions

Creator:: Plasker, James Robert
Abstract:: Accuracy requirements for positioning a vessel in the near shore area have increased in recent years. To meet these requirements several electronic positioning systems have been developed. One such system is the Cubic Autotape Model DM-40. The Autotape is a circular positioning system which utilizes the phase comparison between transmitted...

Simulation of a high voltage direct current transmission system in an electromagnetic transients program using semiconductor terminals

Creator:: NwaChukwu, David O.
Abstract:: In high voltage direct current(HVDC) systems transmission technology, a.c. power is converted(rectified) to d.c. power by means of a controlled rectifier bridge. This d.c. power is then transmitted through a d.c. link to another converter(inverter) where it is converted back to a.c. power by means of another controlled rectifier bridge....

Improved efficiency in medium-power flyback converters

Creator:: Ruttanapaibooncharoen, Surin
Abstract:: Switch-mode power supplies (SMPS's) not only convert energy, they also consume it. Typical operational efficiencies are approximately 25 to 60% for linear power supplies, and approximately 50-90% for switching power supplies. This means that products whose end-use electronics are dc, such as televisions and DVD players, could consume 50% less...

A Microgrid Design Case Study : Synchrophasor Placement and Development of a Protection Laboratory for the Oregon State University - Corvallis Campus

Creator:: Huo, Chen
Abstract:: In the past two years, Oregon State University (OSU) Corvallis campus suffered several power outages. The estimated cost of one of those outages was close to a million dollars worth of equipment and impact on research projects. Meanwhile, the campus grid operates with severely aging power assets. The reliability of...

Towards reliable and survivable ocean wave energy converters

Creator:: Brown, Adam C.
Abstract:: Ocean wave energy is a new and developing field of renewable energy with great potential. The energy contained in one meter of an average wave off the coast of Newport Oregon could supply dozens of homes with electricity. However, ocean waves are usually quite irregular which leads to large bursts...

A linear test bed for characterizing the performance of ocean wave energy converters

Creator:: Hogan, Peter M.
Abstract:: Determining the performance characteristics of various ocean wave energy converters (OWEC) has proven to be difficult due to problems replicating a baseline motion profile in the ocean or wave tank to compare these devices. The linear test bed seeks to mechanically simulate the relative linear motion between the active components...

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...
