Fred and Harriet Cox Senior Design Competition Projects
Part of every UNLV engineering student’s academic experience, the senior design project stimulates engineering innovation and entrepreneurship. Each student in their senior year chooses, plans, designs, and prototypes a product in this required element of the curriculum. A capstone to the student’s educational career, the senior design project encourages the student to use everything learned in the engineering program to create a practical, real world solution to an engineering challenge. The senior design competition helps focus the senior students in increasing the quality and potential for commercial application for their design projects. Judges from local industry evaluate the projects on …

Evaluation Of Highly Efficient Distribution Transformer Design And Energy Standards Based On Load, James Sanguinetti
UNLV Theses, Dissertations, Professional Papers, and Capstones
Power distribution transformers have been prevalent in commercial building distribution systems since the inception of modern commercial electricity. Yet as more and more manufactures seek to improve transformer efficiencies by making changes to the design of the transformer itself, a fundamental concept may be overlooked - the impact transformer demand sizing has on power losses. When modern transformers are improperly sized for the application they will be installed for they are not being utilized at their optimum design loading range, which may impact operating efficiency.
This thesis will aim to test and evaluate modern day transformer design coupled with currently …

Dynamic Modelling Of Single Phase Grid Connected Photovoltaic System, Gopi Krishna Ari
UNLV Theses, Dissertations, Professional Papers, and Capstones
Grid-connected photovoltaic (PV) power systems have been sustaining an exponential growth rate during the past decade. This steep growth is driven by a growing concern about climate change, the adoption of an aggressive regional renewable portfolio standard, rebates and tax incentives, and reduction in PV system cost. One of the main technical barriers that can ultimately limit further PV penetration is the fast variations in the PV system's output power induced by cloud transients. Such events are known to cause voltage fluctuations which may lead to excessive operations of voltage regulation equipment and light flickering.
Solar irradiance variability, which can …

The Problem
• Photovoltaic output power can be affected by many factors including clouds passing overhead.
• Utilities in generally prefer a guaranteed power delivery level over some specified power delivery period.
• Power delivered during peak demand hours is generally more valued by utilities. For the Desert Southwest this is in the summertime afternoons. For the local area this will be defined as 1-5 pm for the three summer months.
• While battery power can be adapted to this problem, large batteries to be expensive.
