Multi-Megawatt Nacelle Laboratory Testing: A Review of Current Capabilities and Future Needs


There is a growing interest around the world in laboratory testing of complete Wind Turbine Systems, with the exception of blades. This is corroborated by recent construction of several testing facilities, as those in NREL and Clemson in US, CENER in Spain, NAREC in UK, LORC in Denmark, and the latest Fraunhofer IWES DyNaLab in Germany, commissioned this summer. Furthermore, the interest in this topic led to the creation last year to the IEA Wind Research Task 35, “full size ground testing for wind turbine and their components”, with the objective of developing guidelines and recommendations for test facilities to simulate in-field loads and test them in a laboratory controlled environment, in order to verify the system design, performance, safety and durability.


This paper, based on the authors’ experience on wind turbine testing and on the design and construction of most of the above-mentioned laboratories and test benches, reviews the laboratory testing possibilities for wind-turbine performance and reliability assessment.

Main body of abstract

The paper analyses the advantages of early testing for designers, manufacturers and project developers.

It will also review and compare, the testing capabilities of the existing laboratories for the different subsystems:

- drivetrain including gearbox and generator
- non-torque load testing capabilities
- power generation including generator and power electronics
- grid simulation capabilities
- control system testing, including HIL (Hardware in the Loop) capabilities.


Finally the paper concludes with a discussion on the needs for standardization as a first step to wind turbine certification , and with an outlook for the next future needs of the market in laboratory testing of full Wind Turbine Systems.

Learning objectives
Understand wind turbine performance assessment through laboratory functional testing, and learn about early reliability assurance through endurance tests.
Identify the existing world multi-megawatt testing laboratories and summarize their capabilities.
Understand the possibilities of business and project risk mitigation through early laboratory testing.
