Presentation at CWP 2016

For the first time SET GmbH is presenting its new innovative product the TRD-unit (Torque Ramp Down Unit) at the China Wind Power 2016 (20th of October, Beijing).

Content:china-windpower-2016 The TRD-unit is a wear-free Eddy Current brake (ECB) which reduces the loads of a WEC in case of a LVRT or any other unpredictable failure.  High stress cannot be prevented, so the WEC has to be designed for these cases. This can be seen by the large amount of material used for WECs (e.g. DFIG) already in operation, which led to an increase in overall costs. To minimize these dimensioning loads, the company SET GmbH from Klagenfurt in Austria has developed a robust, very controllable and cost effective system: a wear-free Eddy Current brake (ECB) mounted on the generator’s HSS under the brand name TRD-unit.  The TRD-unit is an effective option for slowing down a WEC within a short time period, before the WEC´s pitching system is able to react.

This leads to the fact, that the structural loads due to LVRT are no longer dimensional loads. Foundation, tower, rotor blades, gears and bearings can be designed under load reduced conditions. It is expected that the saving of materials lies in the lower two-digit percentage range.
