| ITRI's technology integrates all necessary features to achieve the best possible energy yield out of wind, this especially in the prevalent low and medium wind speed conditions. While operating above up limit speed, our wind turbine has overspeed attitude control actuator to control the rotational speed of the wind turbine within the safety range. Overspeed attitude control actuator reduce the possibility that the blade of the wind turbine and generator are damaged. The permanent magnetism type three-phase generator is connected to our wind turbine and transport electric power to a specific AC/DC/AC inverter delivering best quality power in case of grid connection, which is 110v to 240v of family specification. Better than other competitors, our inverter, through the special design, can accept wide input voltage range from 60 volts to 380 volts, operating from the low wind speed to high wind speed. Last but not least, Intro's WT is designed and realized without compromise, using state of the art components and according to IEC 61400-2 design rules (IEC 61400-1 for class II maximum wind speed). |

ITRI's wind turbine is characterized by a very high efficiency in the lower to medium wind speed range which is prevailing most of the time (>80%). This is achieved by the conjunction of an optimized 3 blades rotor, efficient gear speeding PM generator combined with overspeed attitude control actuator to extend operating range for high speed wind. At high wind speeds, the WT continue to operate at its nominal output, the overspeed being controlled by the overspeed attitude control actuator. These unique features make the ITRI unit the most powerful WT of its class. |

The high availability of ITRI's WT power production makes it a reliable source of cost effective renewable energy throughout the years and weather condition. Its superior low/medium wind performances opens new possibilities for the application of medium size wind power in distributed power production with minimal environmental impact. The various available configurations of the ITRI's WT respond to a very wide range of applications as battery charging, stand-alone AC distribution, island AC grid, public grid intertie, water pumping. It figures as a real alternative or complement to photovoltaic or diesel generation. |

Unlike most of its competitors, ITRI's WT rotation speed is always under control of both electronics and overspeed attitude control actuator. Due to that uncompromising design, maximum rotation speed is limited to 300rpm, involving a maximum tip speed of 79m/s. That’s one of the key to get a quiet running in the entire wind range, low noise, low blade wearing, low mechanical stress. |
