Marie Skłodowska-Curie Early Stage Researcher – PhD position 
General information about the Lidar Knowledge Europe (LIKE) project
 
LIdar Knowledge Europe (LIKE) fosters training and education of young researchers on emerging laser-based wind measurement technologies and their translation into industrial applications. Doppler Lidars (light detection and ranging) that measure the wind in the atmosphere remotely have reduced in price and increased in reliability over the last decade mainly done by European universities and companies serving the growing wind energy industry. This opens the possibility for new applications in many areas. LIKE improves, tests and refines the technology thus expanding these areas of application. LIKE promotes wind energy applications such as wind resource mapping using scanning lidars and control of single wind turbines or entire wind farms in order to increase energy production and reduce mechanical loads. LIKE maps unusual atmospheric flow patterns over airports in real-time and thus improves the safety of landing aircrafts. LIKE explores wind and turbulence under extreme conditions at the sites of future European bridges paving the road for optimal bridge design. LIKE trains 15 ESRs to an outstanding level at European academic institutions and industrial companies, thus forming strong interdisciplinary relations between industry and technical sciences. These relations are implemented through employment of the ESRs at academia as well as industry, and through inter-sectoral secondments. Finally, translation of technology into specific applications is emphasised through the implementation of an entrepreneurship training course LIKE partners, particularly industry.

The Department of Wind Energy in the Technical University of Denmark (DTU Wind Energy) is seeking a PhD for the Section of Meteorology and Remote Sensing.

 

DTU Wind Energy is a mission driven university department with a vision to be the preferred university partner for the global wind energy sector. The department creates value for society through integration of research with education, innovation and research-based consultancy within key fields central to the development and use of wind energy.

 
Please look at www.vindenergi.dtu.dk for more details on the type of activities we undertake. 
 
Responsibilities and tasks

Doppler lidars are increasingly being used in the wind energy industry to assess wind resources and  measure the turbulent wind flow coming onto the wind turbine rotor. Soon, all wind turbines might be equipped with a Doppler lidar. The aim of the study is to improve the capabilities of lidars and prove the improvements by field experiments.  

 

For the class of Doppler lidars called continuous-wave lidar, which can be made cheap and robust, the problem is that the measurement volume is quite large for long measurement distances. This hinders the lidar in measuring turbulence and it also makes the lidar susceptible to moving object in far from the intended measurement point. Both drawbacks are problematic for wind turbine applications. New optical components make it possible to deploy recently invented low-coherence methods that greatly compactifies the measurement volume. The applicant will understand the technology and possibly develop it further, implement it in existing scanning lidars, and test the capabilities of the technique thoroughly in the field.

 
Expected results

The following are the main expected outputs from this PhD study:

1) Understand and improve techniques to make the measurement volume of continuous-wave Doppler lidars more compact.

2) Implement the system in scanning lidar systems used for wind energy research

3) Document the advantages and disadvantages of the technology by field experiments.
