Adopting the advanced and prevalent control technology
Low voltage crossing technology
Variable Speed Constant Frequency
Geoho 850kW wind turbine(GHFD56-850/II)is developed in the same technology platform(Variable Speed Constant Frequency)as prevalent megawatt wind turbine. It is in the form of horizontal axis, 3 blades and upwind. The drive system consists of rotor turbine, horizontal axis, gear box and synchronous generator. The wind turbine system adopts Variable Speed Constant Frequency (electrical independently pitch) control system. Power converter adopts full inverter technology, the synchronous generator is brushless and maintenance free. This wind turbine is efficient, credible and with high performance. More than 130 this kind of wind turbine have been installed and operated well for many years.
