Abstract

The Wind Turbines is excited by natural wind in working environment. The piezoelectric generator gets concern in self-driven, self-powered, micro-electromechanical systems for its environmentally friendly feature, and easiness to get miniaturization. Power Quality is one of the necessary conditions for the normal operation of the generator system, while the output voltage and frequency are the main indicators to measure electrical energy. At rated voltage and power, stable frequency is the guarantee for system working accuracy. According to frequency pump principle, it is effective for piezoelectric transducer to increase gathering power through the adjustment of oscillator parameter and amplification of vibration frequency. The designed Airflow-induced Acoustic -vibration Piezoelectric Generator makes the frequency get close to the natural frequency of the piezoelectric transducer. The result shows that: the frequency of the sound pressure is stable, the vibration source frequency is amplified.
