Overview

Permanent direct drive variable pitch
To be the first 100KW wind turbine designed by gear-less, PM direct drive and initiative variable pitch, which make sure initiative variable pitch with strong wind, stability of output rate, of gaining more power in case of low-speed wind, that technology has acquired patents from nationality.
Annual energy power 300,000kWh(7m/s)
On the average annual wind speed as 7m/s, annual energy power is over 300,000kWh.

Intellectual mult-level protection
Intellectual variable pitch, mechanical brake, electromagnetic brake,initiative yaw system. To ensure that wind turbine generator adjust automatically under unusual condition and reliability of the whole system.
Full power inverter isolation
Full power inverter isolation can ensure wind turbine generator in safety operation, lessen interference for grid.
Application field
Mini-type wind power plant, smart power grid, micro-grid system, on-grid distributed generation in client-side.
