Certification Investigation of Wind Energy Converters (WEC)

The experience from decades of WEC in operation shows that there are still unsolved reliability issues regarding electrical and mechanical components. Moreover, as the share of wind energy increases constantly, it is critical that the certification to be fulfilled before connection to the grid is clear and feasible. Designing the hardware in the loop test benches of the CWD at RWTH Aachen so that they realize repeatable conditions and are fit for certification is one of the main foci of ACS. More

 

Non-linear Power System Modeling, Simulation and Analysis in the Frequency Domain using Behavioral Modeling Approaches

In modern power systems, more and more non-linear components like power electronics devices are present. The non-linearities lead to voltage and current harmonics. Present frequency domain methods assume linear models, which are no longer valid in the presence of more and more power electronics devices. This project aims at developing a new power system theory based in the frequency domain. The used behavioral models of non-linear components are based on measurements. More
