A Study Of The Reduction Of Excessive Energy Generated By Strong Winds On Power Lines Via A Velocity Damping Controller At The Transmission Tower, 2017 Kent State University - Kent Campus
A Study Of The Reduction Of Excessive Energy Generated By Strong Winds On Power Lines Via A Velocity Damping Controller At The Transmission Tower, Donald W. Fincher Jr.
Undergraduate Research Symposium
In this research, we are pursuing the robustness of a self-excited vibrational system with negative damping. In practice, this is manifested as conductor galloping of overhead power lines, which is an oscillation of the lines caused by strong winds. Improved transmission tower designs are needed which are capable of combating excessive stresses exerted on the tower by the galloping power lines. Our model of this self-excited system shows that the oscillations can be controlled by adding a boundary velocity feedback controller at the transmission tower. Using a decomposition method, we show there is a closed form analytical solution which predicts ...

Overcoming The Challenges To Maritime Energy Efficiciency In The Caribbean Region, 2017 Caribbean Maritime Institute
Overcoming The Challenges To Maritime Energy Efficiciency In The Caribbean Region, Deniece Aiken
Maritime energy efficiency in the Caribbean appears to be predicated on two key requirements; regulatory controls over the vessels operating in the region and the availability and use of efficient technology. While many Caribbean territories have ratified MARPOL AnnexVI, implementation of the standards therein, presents challenges that are familiar to maritime administrators of the region. These challenges include insufficient resources and inadequate implementation of relevant standards. These issues have traditionally plagued the region. The paucity of data and monitoring in this part of the world also contributes to ineffective policy interventions. There is also a need to identify the gap ...
The Law Of Conservation Of Energy Towards Defining Maritime Cluster Dynamics, 2017 University of Piraeus
The Law Of Conservation Of Energy Towards Defining Maritime Cluster Dynamics, Peter J. Stavroulakis, Stratos Papadimitriou, Ioannis Koliousis
Industrial clusters have for many decades been considered as the stepping stone for regional and national competitiveness, due to the fact that within these systems of economies, many propitious qualities seem to flourish. Competition and cooperation are witnessed to complement one another, firms can thrive through the marvels of knowledge creation and innovation, and positive externalities are seen to blossom into an interconnected system of collective prosperity. This system bears semblance to many occurrences in nature, and thus can guide the reflection of natural dynamics that may pave an industrial cluster’s threads. Maritime clusters in particular, are distinct vanguards ...
Costs And Benefits Of Lng Economic Development In The Baltic And Arctic Regions, 2017 World Maritime University
Costs And Benefits Of Lng Economic Development In The Baltic And Arctic Regions, Fabio Ballini, Lawrence Kuroshi
Global warming is becoming increasingly evident. However, rising temperatures also offer new economic opportunities, such as new maritime routes in previously ice-locked waters. Valuable minerals in the Arctic region are also becoming more accessible. Maritime stakeholders are therefore seeking to operate in this remote region safely and efficiently. Accommodating these developments from a regulatory standpoint, IMO has amended the International Convention for the Prevention of Pollution from Ships (MARPOL) to include Chapter 9 of Annex I, prohibiting the use of heavy-grade marine fuels as well as heavy-duty oils as cargo carriage in the seas beyond 60th parallel south. In addition ...

Energy Consumption Of Small Scale Fishing Vessel Operations In Indonesia: A Case Study In Palabuhanratu, Indonesia, Vita R. Kurniawati, Richard W. Birmingham, Alan J. Murphy
About 79% of the global fishing fleet is small motorized boats typically operating in coastal areas, supplying local markets, and contributing to human well-being through food supplies and economic development. For example, Indonesian fisheries which predominantly are artisanal fishing, have supported 54% of animal protein intake, accounted for 2% of employment level and increased the fishermen’s prosperity index by 2.44%. However, they cause significant environmental impacts including fish resource depletion and intensive energy use. Balancing the benefits and challenges, sustainably managing these fishing operations is an important yet complex task given the requirements to proportionally account for fish ...

Comparison Of Ac And Dc Led Light Bulb Efficiency For The Dc House Project, Brandon Stafford
This project investigates the efficiency of using LED light bulbs when operated under two different electrical systems: AC and DC systems. The project is in conjunction with the implementation of the DC House system in urban areas. More specifically, this project looks at whether having a hybrid AC and DC system in a typical urban house will increase the efficiency in operating the LED light bulbs, and thus reducing energy consumption and cost. The efficiency of the LED light bulbs are measured by looking at their lumens per watt output. Several light bulbs at four different wattage levels were tested ...
Real-Time Internal Temperature Estimation And Health Monitoring For Igbt Modules, 2017 University of Nebraska - Lincoln
Real-Time Internal Temperature Estimation And Health Monitoring For Igbt Modules, Ze Wang
Theses and Dissertations from Electrical & Computer Engineering
Field experiences have demonstrated that power semiconductor devices, such as insulated-gate bipolar transistors (IGBTs), are among the most fragile components of power electronic converters. Thermomechanical stresses produced by temperature variations during operational and environmental loads are the major causes of IGBT degradation. As the devices are often operated under complex working conditions, temperature variations and the associated damage are difficult to predict during the converter design stage. A promising approach—online health monitoring and prognosis for power semiconductor devices—that can avoid device failure and effectively schedule maintenance has attracted much interest.
This dissertation research focused on real-time accurate internal ...

International Journal of Nuclear Security
Ready access to abundant electricity is a key enabler of modern life. During the past decade the vulnerability of Critical Infrastructure sectors in the U.S. to a variety of natural hazards and man-made threats has become increasingly apparent. The electrical infrastructure (the “Grid”) is the foundation for all other critical civil infrastructures upon which our society depends. Therefore, protection of the Grid is an energy security, homeland security, and national security issue of highest importance. Geomagnetic disturbances (GMD) induced by solar coronal mass ejections (CMEs), electromagnetic pulse (EMP) attacks, and cyber attacks are three events having the potential to ...

Studies Of Uncertainties In Smart Grid: Wind Power Generation And Wide-Area Communication, 2016 University of Tennessee, Knoxville
Studies Of Uncertainties In Smart Grid: Wind Power Generation And Wide-Area Communication, Can Huang
This research work investigates the uncertainties in Smart Grid, with special focus on the uncertain wind power generation in wind energy conversion systems (WECSs) and the uncertain wide-area communication in wide-area measurement systems (WAMSs).
For the uncertain wind power generation in WECSs, a new wind speed modeling method and an improved WECS control method are proposed, respectively. The modeling method considers the spatial and temporal distributions of wind speed disturbances and deploys a box uncertain set in wind speed models, which is more realistic for practicing engineers. The control method takes maximum power point tracking, wind speed forecasting, and wind ...
Design, Control And Protection Of Modular Multilevel Converter (Mmc)-Based Multi-Terminal Hvdc System, 2016 University of Tennessee, Knoxville
Design, Control And Protection Of Modular Multilevel Converter (Mmc)-Based Multi-Terminal Hvdc System, Yalong Li
Even though today’s transmission grids are predominantly based on the high voltage alternating current (HVAC) scheme, interests on high voltage direct current (HVDC) are growing rapidly during the past decade, due to the increased penetration of remote renewable energy. Voltage source converter (VSC) type is preferred over the traditional line-commutated converter (LCC) for this application, due to the advantages like smaller station footprint and no need for strong interfacing ac grid. As the state-of-the-art VSC topology, modular multilevel converter (MMC) is mostly considered. Most renewable energy sources, such as wind and solar, is usually sparsely located. Multi-terminal HVDC (MTDC ...
Photovoltaic Cooking In The Developing World, 2016 California Polytechnic State University, San Luis Obispo
Photovoltaic Cooking In The Developing World, Tyler Watkins, Christopher O'Day, Omar Arriaga
The challenge of clean cooking is faced by hundreds of millions of people worldwide. We present a cooking technology consisting of a solar panel directly connected to an electric heater in a well-insulated chamber. Assuming continued decrease in solar panel prices, we anticipate that in a few decades Solar Electric Cooking technologies will be the most common cooking technology for the poor. Appropriate use of insulation reduces the power demand making low-power Insulated Solar Electric Cooking systems already cost competitive.
