— Wind turbines are increasingly becoming significant components of power systems. To evaluate competing wind energy conversion technologies, a real-time Wind Turbine Emulator, which emulates the dynamic torque produced by an actual turbine has been developed. This is necessary since the real world performance of a wind turbine, subjected to variable wind(More)
Masking-level differences (MLDs) for the repeated high-pass (2000-Hz) and low-pass (2000-Hz) 100-microseconds pulses were obtained as a function of the number of transient repetitions and the repetition rate. MLDs compared to the NoSo condition were obtained for the NoSpi and NoSd binaural configurations (Sd refers to the conditions in which there was a(More)
—This paper presents the development of a wind tunnel that will be used for wind turbine testing in a controlled environment. The prototype is designed to be able to provide wind speeds of up to 20 m/s (~43mph) depending on the cross sectional area of the tunnel chamber. A 42 inch tube axial fan is driven by a 5hp induction motor using a variable frequency(More)
As more sustainable energy generation is integrated into power grid, the control of power flow in an efficient and effective manner becomes more and more essential. A new innovative device is presented that allows the control of line power flow without the high harmonics and efficiency losses of traditional methods. This paper presents the dynamic response(More)
The Cal Poly Sustainable Power for Electrical Resources (SuPER) project is a solar power DC distribution system designed to autonomously manage and supply the energy needs of a single family off-the-grid home. The following thesis describes the improvement and redesign of a MATLAB Simulink model for the Cal Poly SuPER system. This model includes a(More)
This paper applies the electrogeometric model of lightning exposure to a wind turbine to compute its risk of damage due to a direct lightning strike in an area of known lightning flash density. For a typical 45 m wind turbine, the probability of being struck by a downward negative flash, as predicted by the model, agrees with the observed lightning strike(More)
This paper presents a digitally-controlled paralleled DC-DC converter. The main objective of the digital control is to achieve load sharing while operating at close to peak efficiency over an extremely wide load range. Results from computer simulations using Simulink show the digital control could indeed accomplish the objectives, but the improvements over(More)

This paper presents the design and simulation of Multiple-Input Single-Output (MISO) dc-dc converter. The main purpose of the converter is to allow connection of multiple power sources to a single dc bus system. Design and modeling of the MISO converter will first be discussed. Results of the computer simulation will be presented which demonstrate the(More)
