Agenda item 1
Real examples of impact of windturbines on radar operations
Daan Rabijns, Belgocontrol
2 Sustainable Energy – Sustainable ATC Surveillance Workshop Eurocontrol, Brussels, April 2010
4 cases
1. measurable effects of a single turbine at 60 km from the radar
2. severe operational impact: Büchel (GE)
3. severe operational impact: Villancien (Fr)
4. example with tolerable operational impact
3 Sustainable Energy – Sustainable ATC Surveillance Workshop Eurocontrol, Brussels, April 2010
case 1: a single turbine (142m) at 60 km
4 Sustainable Energy – Sustainable ATC Surveillance Workshop Eurocontrol, Brussels, April 2010
case 1: measured impact
primary only
mode S only
combined
5 Sustainable Energy – Sustainable ATC Surveillance Workshop Eurocontrol, Brussels, April 2010
Case 2: unacceptable impact
No track initiation within the cells
Only update of existing tracks

8 Sustainable Energy – Sustainable ATC Surveillance Workshop Eurocontrol, Brussels, April 2010
Case 3: turbines 34 km from the radar
4/6 turbines
142m

9 Sustainable Energy – Sustainable ATC Surveillance Workshop Eurocontrol, Brussels, April 2010
Case 3: turbines 34 km from the radar
10 Sustainable Energy – Sustainable ATC Surveillance Workshop Eurocontrol, Brussels, April 2010
Case 4: tolerable operational impact
11 Sustainable Energy – Sustainable ATC Surveillance Workshop Eurocontrol, Brussels, April 2010
Case 4: tolerable operational impact

12 Sustainable Energy – Sustainable ATC Surveillance Workshop Eurocontrol, Brussels, April 2010
Case 4: tolerable operational impact
13 Sustainable Energy – Sustainable ATC Surveillance Workshop Eurocontrol, Brussels, April 2010
Conclusions
case 1: Impact on PSR can extend to end of radar range
case 2 and 3: Impact not tolerable
case 4: Tolerable impact on ATCO screen
examples can not be generalized
