Error running wind data file

Good day

I am trying to run a wind data file. The simulation starts running, but half way through it gives this error:

compute fail(windpower): invalid stof argument
Simulation windpower failed :compute fail(windpower): invalid stof argument

Any assistance would be greatly appreciated.

Kind regards
Daniel

Hi Daniel,

This error is caused by a missing temperature value in Line 5287 of the file you sent me by email.

I used a text editor to delete the trailing comma(s) at the end of each data rows, and then tried running a Wind simulation in SAM and got a more helpful error message "error reading wind resource file for interpolation at time step 5284: line contains 3 columns, should contain 4." (Because of the two header rows, Time Step 5284 is equivalent to Line 5287, where time steps start at zero and lines start at one.)



Best regards,
Paul.

Hi I am also having issues regarding that error of:
"compute fail(windpower): invalid stof argument
Simulation windpower failed :compute fail(windpower): invalid stof argument"

I have gone through my file to double check any numbers are incorrect or not in the right format but cant see any, I dont know if this is to do with my headings of the csv. 

I am new to SAM ao any help would be greatly appreciated

Cheers

Hello,

There are gaps in your data. For example, wind speed and wind direction data is missing from Row 3950 of the CSV file. Be sure to fill all data gaps before using the weather file in SAM.

Hello,

I am having similar error in simulating a wind farm.

compute fail(windpower): invalid stof argument
Simulation windpower failed :compute fail(windpower): invalid stof argument

I have attached the wind resource file. I have check and there are no gaps in the wind resource file

SAM does not give an error with other wind resource files.

Hello,

There are some "#DIV/0!" values that are causing SAM's wind resource file reader to fail, for example, in Row 7602.

Best regards,
Paul.
