New Methods for Accurately Detecting Lightning Strikes to Turbines
Meet your presenters…
#WindWebinar
Agenda
• The Lightning Problem for Wind Turbines and the Financial Impact
• Tools for Identification and Analysis • Leveraging Your Findings with Emerging Technology • Applying the Technology to Your Business
#WindWebinar
What if you could?
• Monitor the storm in real-time in relation to assets ?
• Do a post storm analysis of all lightning and see which turbines were hit?
• Do a next day inspection inexpensively ?
• Repair the minor damage now and save $$$$ ?
#WindWebinar
The Lightning Problem – Financial Impact
• Lightning Damage = Significant Financial Impact
1. Lightning strikes
account for 25% of loss claims
2. Most damage occurs to blades
3. Blade claims average $240K
#WindWebinar
The Lightning Problem
• Lightning Frequency in the United States.
• High Frequency in High Wind Production Areas
#WindWebinar
The Lightning Problem
• In high lightning areas the likelihood for turbines to be struck multiple times increases
• Degradation occurs over time
• Likelihood for damage increases

#WindWebinar
The Lightning Problem… What the Future will Bring?
• Turbine Height Trend • 110-140 meter Turbines
are coming • What does that mean for
the lightning problem? • What does that mean for
wind production?
#WindWebinar
The Lightning Problem… What the Future will Bring?
The Lightning Problem
• Wind production today • Strong focus in the central
United States
#WindWebinar
The Lightning Problem… What the Future will Bring?
The Lightning Problem
• How improvements in technology change the future of wind production
#WindWebinar
The Lightning Problem… What the Future will Bring?
The Lightning Problem
• Greatest areas of growth occur in geographic areas with greatest concentration of lightning!
• Now factor in even taller turbines = increased strikes and damage
• Climate change = more lightning?
#WindWebinar
How it works
• Detects the electromagnetic frequencies emitted by lightning
• Each sensor has a GPS timer and magnetic direction finder
• Data is sent to a central processor and displayed within 15 seconds of occurrence
#WindWebinar
Accuracy & Coverage
• Precision (< 150 m location accuracy and > 90% detection efficiency) data is available in 50+ countries
• Vaisala GLD360 now provides (< 2 km location accuracy and > 70% detection efficiency) data across the entire world
#WindWebinar
Tools for Identification and Analysis
• Ability to view event in
real-time • Observe the event in
relation to your assets
#WindWebinar
Tools for Identification and Analysis • Ability to perform a post
event analysis • Time is a short commodity • Methods must be fast • Must be simple
#WindWebinar
Tools for Identification and Analysis
• Example of methods available today
1. Selection of asset type
#WindWebinar
Tools for Identification and Analysis
• Example of methods available today
2. Select asset or wind farm
#WindWebinar
Tools for Identification and Analysis
• Example of methods available today
3. Select the date and time
#WindWebinar
Tools for Identification and Analysis
• Example of methods available today
4. Select a window of time to analyze
#WindWebinar
Tools for Identification and Analysis
• Example of methods available today
4. Hit “Go” and within seconds you have your analysis!
#WindWebinar
Interpreting the Results • Did my turbine get hit? • How strong was the
strike? • What is polarity?
#WindWebinar
Interpreting the Results • Taking analysis a step
further.
1. Lightning Ellipse data 2. How is this useful?
#WindWebinar
Interpreting the Results • Daily reports can be
generated • Keep an accounting of a
turbine struck repeatedly • Valuable for collaborative
decisions
#WindWebinar
Leveraging your Findings with Emerging Technology
• The inspection world will change!
• The Drones are coming!
#WindWebinar
Leveraging your Findings with Emerging Technology
• Drones will make inspections faster, easier and cheaper.
• Drones will increase safety of inspections!
#WindWebinar
Leveraging your Findings with Emerging Technology
• 3rd party providers 1. growing list
• Do it yourself • Inspections can be “on
demand”
#WindWebinar
Applying the Technology to Your Business
• Analysis of Lightning Data Matters!
1. Find 25-30% more
damaged blades 2. Early ID = lower repair
costs 3. Minimize turbine
downtime due to focused inspections
#WindWebinar
Applying the Technology to Your Business
• Proven Solutions Exist Today!
1. Simple, Fast and Easy
Methods for Post Storm Analysis
2. Accurate Data to Make Decisions
3. Invest Now, Save Later
#WindWebinar
What can you conclude?
• Lightning is a serious problem
• Technological advances will actually increase the problem
• Accurate blade inspections will become more important
• Technology is available today to mitigate the impact of Lightning
