Control System For A Doubly Fed Induction Generator, Nathan Haines
Control System For A Doubly Fed Induction Generator, Nathan Haines
Honors Theses
Doubly Fed Induction Generators (DFIGs) are typically used in large scale (three to five Megawatt) wind turbines because they can be operated over a wide range of wind speeds, have flexible control systems, power electronics need only pass about 30% of the generator power, and the windmill experiences fewer mechanical stresses. This project is to construct the control system for a DFIG. This control system will be used to test the feasibility of using a DFIG on a small-scale wind turbine. Testing confirms that the DFIG delivers power over a wider range of simulated wind speed than a standard induction …

Maximum Power Point Tracking Device For A Photovoltaic Panel, Betsy Schwartz
Honors Theses
The operating characteristics of a photovoltaic (PV) solar panel are dependent upon the lighting and temperature conditions, as well as the characteristics of the energy storage device and/or loads that it feeds. PV panels normally operate at a fixed voltage and current for a given load and sunlight condition. The operating conditions will not necessarily produce the maximum possible power output of a solar panel for the set conditions. The efficiency of power delivery from a PV panel can be greatly increased by a Maximum Power Point Tracker (MPPT). An algorithm can be designed to shift the operating value to …
