Project: Research project – Suitable wind turbines for the implementation of main bearing units with plain bearings in the 5 MW range

Webseite Chair for Wind Power Drives

The Chair for Wind Power Drives researches the behaviour of drive trains of modern multi-megawatt wind turbines (WT). The research goals are to increase the availability, robustness and energy efficiency of wind turbines and to reduce the levelized cost of electricity. To this end, software development tools and modern system test benches are used in combination.
Current WT exclusively use roller bearings as their main bearings. However, in the event of failure, these cause high repair costs. For this reason, intensive research is being conducted regarding the use of plain bearings as the main bearing of wind turbines. Among other things, these enable the replacement of individual bearing segments, which significantly reduces repair costs in the event of failure.
Therefore, a plain bearing main bearing unit in a relevant size range (5 MW) is to be developed at the CWD.
This work therefore aims to provide an overview of relevant turbines and subsequently evaluate them with regard to their basic suitability for the use of main bearing units with plain bearings.
