Abstract

The demand for renewable energy has increased in recent years, including the market for micro wind turbines. However, low-cost products lack a proper control system and advanced features. This paper improves on an integrated control system with real-time monitoring and braking capabilities. The prototype uses off-the-shelf components, reducing costs and not needing constant maintenance. The control electronics include a three-phase rectifier and a DC-DC converter to regulate the output voltage. To allow real-time control, a microcontroller measures the voltage, current, and turbine speed. An emergency stop button is also implemented to stop the turbine with an electronic brake. Primary system performance data is displayed in a user interface by a Raspberry Pi and stored for future analysis. Experimental results demonstrate the feasibility of the proposed control system for commercial micro wind turbines of 200 W and 400 W.
