Acoustic properties main gearbox

Since the productive onshore sites for wind turbines are limited, currently the installation sites grow closer to residential areas. Hence the acoustic emitions of the wind turbines become more and more critical.

Pitch System

Modern variable speed wind turbines have adjustable rotor blades for power control. Today, for safety reasons one pitch drive per blade is required to control them independently, so that even in cases of the loss of one pitch drive, the system can still be braked aerodynamically.

Trailing Edge Flaps

The time-varying wind loads on the rotor of a wind turbine (WT) can cause damages within the drive train. It shall be investigated to what extent active aerodynamic measures, such as flaps on the rotor, can reduce these loads.

Alternative drive train concepts

The fourth work package focuses on the analysis of innovative drive train concepts in order to increase the economic efficiency and the technical availability of wind turbines.

Condition Monitoring System

The goal of this work package is the development of a cross-system condition monitoring system (CMS). With a CMS the operation state of a wind turbine can be determined and supervised.

Certification

One of three research topics is the development of certification procedures for the overall system, which can be performed on the basis of test bench measurements. The aim is to provide an optional replacement of the insitu measurements that are currently destined in the IEC 61 400.

Development of two test rigs

At RWTH Aachen University two new WT system test rigs with different power categories are built up. In the project's first phase an already exisiting universal test bench is configurated for a 1 MW nacelle system test rig.

The second phase covers the entire construction of a 4 MW WT system test rig for the analysis of the dynamic operation behaviour of WT nacelles at the Center for Wind Power Drives at RWTH Aachen University
