The aeromechanical pitch regulation system The blades are turned around their axles by the stabilizers which are placed behind trailing edges of the blades. This system was proposed by professor G. Sabinin in the fifties. We improved this system by changing the method of stabilizer deflection. Our aeromechanical pitch regulation system ensures reliable and effective Wind turbine operation at the wind speed from 2. 5 to 55 m/s even when wind is gusty. Low rated wind speed Our wind turbines have rated wind speed about 7. 5 – 9 m/s. It is lower than rated wind speed of the most similar wind turbines of the other manufacturers. Technology description

The comparison of VEU-075 with two other windmills. VEU-075 has higher power in the most widespread range of wind speed (from 3 to 7 m/s). So , it produces more energy per month at the same average wind speed. WEU-075 Instantaneous power dependence on the wind speed Power output dependence on the average wind speed (per month) The differences and advantages

The CCU differences and advantages Technologies Strengths 1. multipurpose integrated Our hybrid control and technology Weaknesses converting unit 2. temperature compensation 3. special regime`grid energy saving We need to increase numbers of the additional functions, for example: parallel works with diesel and gas generators; using of several types of storage batteries. Southwest Windpower, USA 1. SRC-based shunt –type controller 2. Compatibily with any inverter 1. Not multipurpose control and converting 2. Not integrated hybrid unit. Green power, Germany 1. multipurpose (water) integrated hybrid control and converting unit 1. Not ‘sinus’ output AC.
