Abstract

Wind turbines can operate at their maximum power coefficient under variable wind conditions if they have variable speed capabilities. A simple control scheme allows induction generators to operate at an optimal speed for a given wind speed. This scheme uses a standard V/Hz converter operated to give the frequency required for the given shaft speed and power requirement. Small signal analysis of this control shows it to be stable and have a bandwidth suitable to track the wind. Simulations and experimental results show the system to work well
