Traditional doppler radars have hard time separating weather from

non-meteorological phenomenons. Knowing the velocity distribution

surely helps.

doppler radars have unambiguity problem with high wind speeds. Eigenor WnD offers a solution.

Radar revolution

•Eigenor solution upgrades the wind speed metering scale from 8 m/s to to 50 m/s•Range is extended from 200km to 250km on the same equipment

Eigenor technology on radars

1. Weather radar analysis

•According to spesi!cations / needs of radar operator like FMI•Analysis of clutter and and other effects, both local and non-

local•Comparison with other clutter effects on the site•Mitigation / reducing effects•Deliverable: report 30-40 pages

• Estimates of short-term production are vital for pro!t maximisation in large wind farms.

• Bene!ts

• Renewable energy sources become more competitive

• Reduced CO2

• Better prices (extra EUR 1-3 per MWh)

2. Predicting windpower output

3. Increased production

1. Improved directional control

2. Basic pitch controlWind radar can offer very accurate wind speed information in advance.

3. Advanced, individual pitch control

4. Gust prediction, warnings, for mechanical stress analysis

These bene"ts can be achieved with both local and non-local weather radars.

Korea - how it did work for us

• Active local partner with existing contacts• Marketing materials

• Strong localization

• English is not always enough

• Sample images and use cases! Scienti"c background irrelevant

• Proof-of-Concept needed, free of charge• 2 Trade fairs, booth and a seminar arranged by TEKES and

a local partner• Application areas: medical, industrial, wind energy
