Design and Implementation of a Grid-Connected Wind Energy Converter to Recycle the Wind Energy Provided by Industrial Exhaust Emission

The heat exchange gas for heat, ventilation, and air conditioning (HVAC) and industrial processing are generalized industrial exhaust emission. In order to increase the heat exchange efficiency, condensed gas must quickly take away the heat energy from the condenser. When the exhaust emission is released to the atmosphere, the possessed kinetic energy is usually large enough (above 10m/s) to be recycled in the form of the electrical power. In this project, a small scale Darrieus wind turbine featured with low drag blades will be built at the exhaust outlet. Low drag blades of the wind turbine are beneficial to extract the wind energy from the exhaust emission without affecting the heat exchange efficiency. In addition, due to that the kinetic energy of the exhaust emission is usually stable, a grid-connected wind energy converter with battery-free configuration in the low energy loss and low cost senses will be designed to recycle the exhaust emission. In this project, the grid-connected wind energy converter will be implemented by a voltage-sourced inverter (VSI), the maximum power point tracking (MPPT) technique will be utilized to track the optimal operating points. Furthermore, the power factor correction (PFC) technique will be designed for the VSI such that total harmonic distortion of the voltage can be suppressed below 5%. Since all material in the wind energy recycling system are made in Taiwan, the superiority, such as high efficiency, low cost and energy saving, of the system over the traditional wind turbine in the market will be expected.
