Off Grid Solar Powered Street Light, Justin Fang, Billy Pham

Electrical Engineering

Street lights are fixtures found in every city and serve the important purpose of illuminating the streets and keeping the roads safe for pedestrians and drivers. Current street lights are powered by the grid, power which is paid for by the taxpayers and could have been used to power homes instead. With this project, our goal is to design and implement an electric power system that collects and stores solar energy, and delivers power to an LED smart street light. The resulting system would reduce street light energy costs by 100% since they would not draw any power from the …

Cal Poly Wind Power Research Center Power Regulator, Ricardo Rodriguez, Steven Bounchareune

Electrical Engineering

Through funding from the California Central Coast Research Partnership (C3RP) the

CPWRC, led by Dr. Patrick Lemieux, has erected a horizontal axis wind turbine (HAWT) at the

Cal Poly Escuela Ranch site EL04. With the help of Dr. John Ridgely and Dr. Art MacCarley, the team has implemented a controller that delivers the power being generated by the turbine to a resistor bank which maintains a safe working speed for the turbine. The authors objectives for this project are to (1) become familiar with the operation of the turbine, (2) develop an AC-DC converter that regulates the output of the …
