Wind Farm Simulation Produces Almost Zero Output was created by Aliiii
Hello,I'm currently working on a wind farm simulation in SAM using the Wind Power module with real location data from NSRDB (converted to
format)
Problem:
Even though the resource file is valid and accepted by SAM, the simulation result shows an Annual AC energy of only ~1 MWh, and a capacity factor of 0.0%, which is not realistic for a 301.3 MW wind farm using Siemens SWT-2.3MW-101m turbines. Here’s what I’ve checked :
Code:
.srw

- The
file which is valid and accepted by SAMCode:.srw
- The turbine selection is correct from the SAM library.
- The layout contains 131 turbines properly located and imported via CSV
Attachements: -
file structureCode:.srw
- Wind turbine selection and specs (Siemens SWT-2.3MW-101m)
- Turbine layout imported (131 turbines)
- Simulation output showing 0% capacity factor and monthly AC output chart
- Sample hourly data showing non-zero wind speeds but no generation
Can someone help me understand where i went wrong or why SAM fails to generate close to realistic power output from this setup?

Hi Aliii,
The atmospheric pressure data in your file appears to be in the wrong units: The values are on the order of 1000, but I would expect them to be on the order of 1.
Please try replacing the pressure data with values divided by 1000.
Best regards,
Paul.
