EWT DW-52 500kW: Is the capacity factor for real?
EWT DW-52 500kW: Is the capacity factor for real?
(OP)
Hi,
I have being doing a little research on medium wind turbines for a masters thesis. Mainly around the 500kW mark. I have come across a wind turbine produced by EWT in the Netherlands. It is a DW-52. When I look at the power curve data I see that at 9m/s wind speed at the hub it produces roughly 440kW equating to a capacity factor of 88%. Now this seams to be very high when you compare it to a TurboWinds T500-48 or a wind Flow 500. Granted the EWT uses direct drive technology.
Has anyone had any experience with these turbines? Any real world data on these machines? I've looked but it's slim pickings out there...
