The only hybrid in wind power market

Wind turbine DS3000 is a 3kW nominal power vertical axis small wind turbine that combines in its structure a dual system consisting of Darrieus blades that guarantee high efficiency and Savonius blades, which enable the system to be activated with very low winds. This technology mix makes the Hi-VAWT turbine a highly innovative product: equipped with controllers capable of managing the maximum battery power and direct magnet drive generator.

These turbines are built according to the IEC 61400-2 certification, a very important factor for small power generators. The dimensions of the product perfectly reflect the technology of a vertical axis that is truly capable of generating 3000W of power with wind at 12m / s, and accumulating from 20 to 40 kWh per day with winds between 9 and 12m/s.

Perfect for weak winds and efficient for strong winds

The peculiarities of the DS3000 turbine allow to obtain a possible annual production that abundantly exceeds 6.000kWh with average winds higher than 6m/s.

MECHANICAL FEATURES

Unique Hybrid Technology

The turbine with double rotor that facilitates starting with the wind breeze and increases exponentially with medium strong winds up to 18 m / s. IEC 61400-2 certified in South Korea and Japan, BWEA conformity test completed at TUV NEL laboratories (UK), JWSTA certification in Japan for the sale of energy as well as in the US and UK

  • A: Darrieus blades made of aluminum, with arched wing curve, to better distribute the tension force, to optimize wind capture and increase energy production.

  • B1: upper fixing plate of the Darrieus blades, the blade connection has been designed to eliminate possible breakages with very strong winds and reduce the possibility of damaging the generator in case of blade breakage.

  • B2: Savonius blades, perfect as they are oriented on the four cardinal points to capture the wind from any direction, without the need for rotor orientation.

  • B3: vertical axis of the turbine, made of ASTM A283 grade D steel (better known as SS400) suitable for working with temperatures of -20 ∼ +40°C.

  • B4: upper fixing plate of the Darrieus blades, the blade connection has been designed to eliminate possible breakages with very strong winds and reduce the possibility of damaging the generator in case of blade breakage.

  • B5: permanent magnet generator of direct drive type, bearings with high resistance to high temperatures, a fundamental characteristic for working with constant strong winds, where mechanical stress is very strong.

  • B6: Manual mechanical brake, this protection system acts on rotation and is mainly used for maintenance and machine downtime.

  • B7: overvoltage wire for the manual brake to be welded to the pole with relative “C” support.

  • B8: dumper, a fundamental component to minimize vibrations and therefore the noise of the turbine.

  • B9: R/S/T three-phase generator cables prepared for connection to battery charger controller or network inverter.

  • C1-2-3: various screws for Darrieus blade connections, turbine flange on the pole.

INSTALLATIONS SAMPLES

Mini wind farm

Japan. Installation of 6 3kW turbines for the sale of energy. Advantages of the 18kW wind farm: minimal environmental impact thanks to the 8m poles, the aquifers are not affected thanks to the shallow foundations, in case of machine stoppage the park continues to produce energy.

Parking lot

Taiwan. Installation at a parking lot for the total sale of the energy produced, three 3kW turbines installed on 6m high poles for a total 9kW power. 

TLC Radio Towers

Mongolia. Installation of 1 3kW turbine in combination with photovoltaic and generator set, energy mix to make the telecommunications tower self-sufficient in an area isolated from the electricity grid. The battery storage solution makes the energy produced always available.

1,2MW Wind farm

Taiwan. Installation of 432 3kW turbines for grid connection and green energy production. The project ended in June 2018 thanks to the investment made by the Taiwan Power Company in the wind energy district of Wanggong
