The aim of this research is to evaluate the behavior of small scaled wind turbine system against strong wind input using electromagnetic stall control system. In general, the wind turbine system is generating energy from the revolution of blades. The revolution of blades is depended on the velocity of wind. Therefore, if there is strong wind then the revolution of blade is increased and consequently more energy will be generated. Therefore, generally the wind turbine systems are located in the gale area in order to generate energy efficiency. However, there are some limitations of the revolution of blades or the angular velocity of blades, especially in small-scaled turbine. If the angular velocity exceeds the limit of revolution, then wind turbine system may breakdown. Thus in this paper, in order to avoid the malfunction of small-scaled wind turbine system, electromagnetic stall control (ESC) is suggested. ESC can control the angular velocity without having any connection with shaft. Thus, we would control angular velocity much efficiently than the conventional stall control method such friction stall control. As a consequence, we could verify the reliability of ESC system.
