New concept from Flender

The Berlin manufacturer of electricity generators, Flender ATB-Loher, part of the Deutsche Babcock Group, says it has developed "an innovative electricity generation concept for the wind turbine industry" together with SEG of Kempen, which specialises in electronic controls. Both companies are substantial, with 3200 and 500 employees respectively. Prototypes of the new generator system are to be put to use in 1.5 MW Tacke Windtechnik machines and 500 kW DeWind turbines installed before the end of 1996. Flender and SEG formed a consortium on April 1 to build the so-called Concycle variable speed generator system, designed for wind turbines with rated capacities of 500-2500 kW. According to Joachim Zwick, wind energy branch manager at Flender ATB-Loher, the Concycle generator "cuts torque and related mechanical forces as well as reducing temperature changes within the generator leading to a longer component lifetime. Clear advantages are also achieved in grid compatibility, for example in setting the power factor, avoiding grid flicker and soft disconnection from the grid." He adds that in a first for the wind industry, use of the Concycle system allows turbines with asynchronous generators to be operated in stand-alone operation, opening up a whole new market for the wind industry.
