Deutsche Windtechnik repairs converter controls

Bremen - Deutsche Windtechnik AG, the market leader among manufacturer-independent service providers, has developed a virtual wind turbine. The system simulates the environment of the wind turbine control and primarily serves to test converter control elements. Thanks to this new development, the company can now repair converter control elements, which is a first among manufacturer-independent service providers.

Deutsche Windtechnik uses the virtual wind turbine to test the functionality of repaired converter controls and the quality of the repair. The system simulates the environmental signals of a real wind turbine at the test facility of Deutsche Windtechnik Steuerung GmbH in Viöl (Schleswig-Holstein, Germany). In addition to the wind conditions, the voltages and power grid currents are also simulated. Moreover, the virtual wind turbine simulates the pitch angle, rotational speed, voltages and currents of the generator.

Lower costs, higher availability
“One of the components that we have to replace most often in our wind turbine is the converter,” explains Karl Keusgen, CEO of Deutsche Windtechnik Steuerung GmbH. “Because our repairs are much quicker and more cost-effective than installing new controls, our new service increases both the economic efficiency and the availability of our wind turbine generators.”

Deutsche Windtechnik AG now offers the new service globally for Vestas type V52, V66 and V80 turbine converters. The service is expected to be rolled out to other turbine types next year. “It is important for us to be able to develop our own solutions alongside repairing electrical components,” adds Keusgen.
