  • How will the industry react to the standards coming up?
  • What will be the impact on the financial side of things?
  • What additional areas of wind energy in cold climates need attention?

What Is The ideal Ice Sensor For Pre-Construction?

  • The importance of avoiding ice growth on sensors and/or meteorological met masts to avoid measurement errors and data loss
  • Using LIDARs as an ice detector
  • Benefits and limits of heated anemometers on:
    • Icing analysis
    • Measurements
    • Pre-construction assessment
  • Are icing duration and severity the only two criteria that make up an ideal sensor? 

Timo Karlsson, Research Scientist, VTT

11:30

Analysing How Ice Impacts The Measured Wind Speed And Uncertainty Analysis

  • Avoiding measurement errors due to icing on sensors in order to gain an accurate energy yield estimate
  • Increasing data availability to lower uncertainties and implement long term correction
  • Converting measurements into predicted effect on power production
  • Keeping in mind access and mast collapse as additional factors for ice impact on uncertainty analysis

Mark Zagar, Meteorologist, Vestas 

12:00

Estimation Of Icing Losses By Using Site Short Term LIDAR Data

  • Methodology and set up of Lidar measurement devices for icing measurements
  • Analysis of LIDAR data for short term meteorological icing
  • Verification with onsite met mast data and reanalysis data
  • Comparison of site measured icing data with icing maps

HIGH FREQUENCY TALKS 

Getting Accurate Data Out Of Your Wind Farm

The aim of these high frequency talks is to facilitate a discussion on how accurate data can not only help mitigate risks in pre-construction but also have a beneficial impact on operation and maintenance activities being performed on sites affected by cold climate and icing issues and, ultimately, use data to bring down costs and enhance AEP.

Each delegate will be given the chance to express their thoughts, concerns, ideas and solutions anonymously and in written form (5 minutes) through an online platform called Sli.do. The moderator will then read out  the audience’s suggestions on how the industry can progress on these issues. The debate will then be opened up to the rest of the room, making this the perfect occasion to take a real step forward on the use of data.

Please come prepared with lots of thought provocative and insightful questions and comments! 

Moderator: Ville Lehtomäki, Senior Scientist, VTT

Speed Networking

Realising the importance of connecting with your peers, we organised a moderated networking session where delegates are prompted to meet others in brief 3-minute rounds. The moderator will be keeping track of time and announcing participants when to switch partners.

Make sure you bring lots of business cards along with you!
