| Abstract |
The contribution presents findings about reliability of electrical subassemblies of wind turbines. It shows that failures of the electrical system appear frequently and that the share of these failures is
increasing with ongoing technical development. However, the faults of electrical subassemblies are
wide-spread over numerous subassemblies. By analyzing the electrical system, it can be seen that the
share of electrical subassemblies affected shows a uniform distribution. A closer look at the converter
in particular shows that failures of the converter are one half each due to failures in semiconductor parts. Since detailed documentation of all maintenance measures of a large population of plants and a purposeful structured database are necessary to extract sound conclusions out of the operational experience, an outlook about gathering and evaluating future operational experiences of on- and
offshore wind farms will be given. |
