The dependent sources use the regressionequations shown in Figure 4 to relate terminal voltage to the 5th, 7th, and 9th harmonic currents.The constants in the relationship reflect scaling to produce peak current values.

The given wind speed will be the reference speed to themotor system, i.e., the presumed wind speed will be converted to a reference voltage to drive themotor. The presumed wind turbine PMDC generator is connected to the presumed wind turbinemotor, rotating at the same speed and generating corresponding voltage values. The teams weregiven the following concept questions during the actual laboratory and were asked to include thecorresponding answers in their technical laboratory report: Q) Investigate the wind turbine mathematical equations, explain the variables affecting the power & voltage generation, and introduce another parameter to reflect real-life

is a strategicissue of great importance to the nation. With society’s growing need for energy and energy-related workforce, many institutionsare vying to take advantage of these opportunities and challenges. Some academic institutionswith traditional engineering programs (e.g., chemical, civil, mechanical, electrical and nuclearengineering) have created departments and/or programs in energy-related areas to reflect thegrowing need and trend. To move The Pennsylvania State University to the forefront in energy,the Department of Energy and Mineral Engineering proposed a formal undergraduate degreeprogram (Bachelor of Science) in the growing field of energy engineering. The program benefitsstudents of several colleges at The Pennsylvania

1 percent of total energy consumption is solar, compared withroughly 85 percent from oil, natural gas, and coal1.Even though a number of technologies are already available, improving them to a level that leadsto widespread use of solar power requires continued research and engineering efforts. This workfocuses on one of these technologies, namely the photovoltaic (PV) systems.PV systems are comprised of photovoltaic cells. A photovoltaic cell is designed to convertradiant energy in light to electrical energy that can be used to power devices. They are usuallymade of semiconductors, like silicon, and have an anti-reflective coating. In a photovoltaic cell,one side has a positive charge and the other side has a negative charge. When photons

In courses focused on learning the tool, rather then the application, students canbecome muddled in the nuances of the tool rather then its overall usefulness to the discipline.This is the impetus for adding this component to a required class in the sophomore level.Students were informed on the syllabus that certain assignments would be computer intensiveand the point value for these problems would reflect the amount of expected effort. It was also Page 22.1642.2noted on the homework

officially began in Guthrie on Christmas Eve 1890 in the McKennon Opera House whenTerritorial Governor George W. Steele signed legislation providing for the establishment of anagricultural and mechanical college as well as an agricultural experiment station in PayneCounty, Oklahoma Territory, effective December 25, 1890 [5]. At long last, Stillwater wasdesignated as the location for the college by the designated commission. On May 15, 1957,Oklahoma A&M changed its name Oklahoma State University of Agricultural and AppliedSciences to reflect the broadening scope of curriculum offered. However, the name was quicklyshortened to Oklahoma State University for most purposes, and the "Agricultural & AppliedSciences" name was formally dropped in
own pace but not so much deciding in what order to learn. It is very plausible that, while Page 23.602.15the course materials and virtual lab are available at any time, the sequential presentation of someof the scientific content of the modules limit in what order the modules could be completed. Thetasks to complete each module are clearly stated and the perceived interactivity of the course andexperiments reflects that the choices that students make are meaningful and not just not for thesake of making choices.However, in general, the responses amongst the surveyed groups (students, graduate students(TA) and instructors) showed little

Continuous project refinement is needed to ensure thatprojects are well-defined and tractable for students. All projects will require regular feedback andinteraction with facilities staff to ensure both project relevance and implementation of projectresults. Finally, the continued pursuit of institutional-level resources will be needed to providethe

They would much rather befree to skip class when they want to and get the notes off the web or from a friend. With the firstclass I taught using clickers, this was a major issue and was reflected in the end-of-termevaluations. In the conclusions section, I will describe how I tried to deal with that with mysecond class.The final disadvantage, that I have found is that it takes time to develop good questions andmultiple choice responses for use in class. The numeric format of the clickers only allows asingle number to be entered, so numeric problems must be structured to allow the students toenter the numbers in a reasonable format (e.g., rather than
GammaFig. 14: Simulink/SPS model of the CIGRE HVDC Benchmark systemLecture 3Simulation: The HVDC system simulated in this study is modeled based on the CIGRE HVDCBenchmark system. For the simulation, a time-step of 50 µs is customarily chosen, which isslightly less than 1″ for a 50 Hz waveform. To implement the model with Simulink/SPS, a totalof 109 states; 37 inputs; 86 outputs; 31 switches were used. Matlab 7.6.0 (R2008a) was used toconduct the simulation. The normal operation of the HVDC system is affected by faults on theDC line, converters, or the AC system. The impact of a fault is reflected through the action ofconverter controls. In an AC system, relays and circuit breakers are used to detect and removefaults. On the other hand, the faults

Generally the 4 roof corners are sufficient, whilesometimes due to shading, pictures of the pathfinder must be taken in middle sections of the roof.The data found in each of these readings can be used to find a total yearly average for the entireroof area.To use, place the pathfinder as close to the roof surface as possible and level it. The pathfinder’sreflective dome makes it possible to perform assessments on a less than sunny day. In fact, if theSun is too strong use the field notebook to block the Suns reflection in the pathfinder as shown inFigure 9. Figure 10 is an example of how effectively the pathfinder works on a cloudy, evenraining day. If the pathfinder is completely shaded by

severaldays, the power generation curve from the solar panels under smoggy conditions remained“smooth”.Table 7 lists the peak and average power output for each converter type, as well as the total dailyenergy generated under smoggy conditions. From the data, it is evident that the smog diddecrease the power generated from the solar panels but not to the same extent as that of shadingthe panels. This is because even with the smog, diffuse and reflected irradiance were able toreach the solar panels.

to note that the diversity among BPHS studentswas reflected in the EE students. Page 26.1232.10While BPHS students engaged well with the tables staffed by Suffolk EE faculty and students,these exhibits would have benefitted from the types of signs that the industry had to orient the 9students about what they were learning. They also would have benefitted by having seatsarranged around their exhibits and the industrial presenters had. The Suffolk EE studentsinteracted with and engaged the BPHS students at this exhibit quite well, and the Tesla coil had apalpable ‘wow’ factor.There were other
equipment, antennas, etc.).Depending on the location, these objects could be considered to either obstruct the IFOV of thesolar panel and lux, or could potentially reduce the availability of reflected light off of nearbyspecular surfaces to increase available light to the systems. Although this situation wasconsidered, the students could not come up with a way to mitigate this confounding. Therefore,no further attempt to normalize the variable, besides compensate for lux to output, wasincorporated into the study. Finally, while the decreasing temperature throughout the course ofthe study likely had bearing on numerical outcomes, preliminary analysis suggested thatfactoring in the theoretical effect would not have altered the overall consensus of

The students were asked to reflect on their involvement in the project, andthen rate how their participation affected their learning in six areas, as indicated in the following: 1. Ability to work as part of a large interdisciplinary team of technical and non-technical professionals. 2. Ability to write a real request for proposals and evaluate the responses. 3 Ability to consider life cycle issues when specifying components and identifying vendors. 4

In the future, the controller will no oversupply the load, as can be seen from time 0 - 4.5 s, instead this power will be used to charge the battery. The load of the simulation will also be updated to accurately reflect the transition in demand of the variable load, opposed to the current, instantaneous changes in demand. This poses a future challenge of programming a controller to recognize the changing demands from the load and activate the battery to improve system response. ResultsI.
