This machine Is the first series arc machine installed
In the city of Portland. It was obtained by
the Electrical Department of O.A.C., with the object
of rewinding it for a high current machine to be used
in the charging of storage batteries.
This research introduces an energy storage system to deliver microgrid frequency response. A doubly-fed induction generator (DFIG) and a squirrel cage induction machine (SCIM) are coupled together as a motor/generator set to deliver an immediate inertial response to a change of frequency, and an inverter and supercapacitors deliver short term...
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...
This thesis introduces a Brushless Doubly-Fed Machine (BDFM), stand-alone
generator system. Development of a BDFM current-forced model, along with the
analysis of air gap power distribution between the two stator windings and the rotor
circuit, pave the way for the characterization and analysis of stand-alone generator
systems.
The main disadvantage...
Electricity is the name given to an invisible agent known to us only by its attendant phenomena and by various manifestations called electrical. These manifestations, at first obscure and even mysterious, are now well understood. Indeed its great importance to mankind can only be realized when we remember that it...
The loads on the electrical systems of automobiles are projected
to increase significantly in the near future. This will result in a
requirement for improved efficiency over the present-day car
alternators. An alternative scheme proposed at Oregon State
University employs a Brushless Doubly-Fed Machine (BDFM) as an
alternator.

Driven by the need for high energy-density power sources, demand has
stimulated the development of small-scale engines. A small-scale engine
with a fuel supply could replace batteries and utilize higher energy-density
liquid hydrocarbon fuels; such an advance could deliver a new age of
portable devices. Currently, operable small-scale engines exist;...
