Abstract
The purpose of this study is to harvest vibration energy of a water turbine in a hydro power plant in a laboratory scale environment. The system used in this paper consist of an accelerometer to measure acceleration of the vibration, a piezoelectric generator to convert vibration energy to electric power, a clamp part to hold the piezoelectric generator, and a capacitor. Vibration analysis was performed to find frequency of the area around the water turbine using Fast Fourier Transform (FFT). The generated electric power was stored in the capacitor. The results of analysis and experiments are presented and discussed.
