ENERCON GmbH products

When it comes to yield, noise emission and stress minimisation, ENERCON’s rotor blade concept sets new standards in the wind energy sector. Because of their modified shape, the blades not only draw energy from the outer edges but also use the inner radius of the swept area, considerably increasing power output. The new rotor blades are also less susceptible to turbulence and provide an even flow along the entire length of the blade profile. In addition to the new design, the blade tips have also been improved to reduce noise emission and increase power output. Turbulence at the blade tips due to overpressure and underpressure is effectively eliminated in the rotor plane. The entire length of the blade is therefore utilised without any loss of energy caused by turbulence. The blades’ high efficiency is reflected in power curves taken on all ENERCON wind turbines where power coefficients (Cp) of more than 0.5 are achieved.

All ENERCON wind energy converters are equipped as standard with an ice detection system, which is based on a specially developed power curve analysis method. During operation the ice detection system compares current operating data such as wind, power and blade angle with the recorded long-term mean values. Ice build-up on the machine changes the aerodynamic properties. The WEC is brought to a halt and the de-icing procedure is initiated.
