Examination of Power Systems Solutions Considering High Voltage Direct Current Transmission
(Virginia Tech, 2015-10-05)
Since the end of the Current Wars in the 19th Century, alternating current (AC) has dominated the production, transmission, and use of electrical energy. The chief reason for this dominance was (and continues to be) that ...
Model order reduction of linear dynamic systems with application to power system control
(Virginia Polytechnic Institute and State University, 1974)
Steady-State Analysis in Transmission System Planning per Latest TPL-001-4 NERC Standard
(Virginia Tech, 2016-01-19)
Several cascading outages that have occurred in the past have shown the importance of performing appropriate and coordinated transmission system planning between the different Planning Coordinators and Transmission Planners ...
Application of non-uniform sampling techniques to digital filter synthesis
(Virginia Polytechnic Institute and State University, 1979)
Swept Neutral Pressure Instrument (SNeuPI): Investigating Gravity Waves In The Ionosphere
(Virginia Tech, 2015-09-08)
A swept neutral pressure instrument(SNeuPI) is used to study the effect of gravity waves on the composition of the ionosphere. When mounted on a nanosatellite in the low earth orbit, changes in atmospheric pressure due to ...
Characterization of Optical Coupling and Back-reflection of Few Mode Fibers
(Virginia Tech, 2015-09-01)
The continued growth of the communications industry has caused interest in mode-division multiplexing (MDM) techniques to flourish in recent years. These techniques allow individual waveguide modes to be used as distinct ...
Design of control electronics for the Ram Energy Distribution Detector
(Virginia Tech, 2015-09-03)
The bulk motion of the neutral gas at altitudes between about 200 and 600 km is an important factor in predicting the onset of plasma instabilities that are known to distort and/or disrupt high frequency radio communications. ...
Automotive Lead-Acid Battery State-of-Health Monitoring System
(Virginia Tech, 2014-09-05)
This thesis describes the development of a system to continuously monitor the battery in a car and warn the user of an upcoming battery failure. An automotive battery endures enormous strain when it starts the engine, and ...
Alternate Fault testing on a Bus on a Dynamic Position Vessel
(Virginia Tech, 2015-09-18)
Direct fault testing onboard Dynamic Position Vessels is a requirement to maintain the ships classification and ensure redundancy of the power system onboard to maintain position. The most vulnerable part of the ship when ...
A compact multicolor display for vectorcardiograms
(Virginia Polytechnic Institute and State University, 1976)
