LK and SAM automation

Hello
I am using the LK to simulate a SPT with different attenuation levels. I succeeded to get The Field Optical Efficiency [eta_field] as an hourly output after calling 365 attenuation values for each one of the 4 polynomial coefficients in the atmospheric attenuation section.

The problem is when I try the same for other outputs such as (The Receiver Incident Thermal Power [q_dot_rec_inc], The Field Incident Thermal Power [q_sf_inc] or The PC electrical power output, gross [P_cycle]) I have nothing. Simulations keep giving ''Null'' ..

I attached the LK script in a notepad file, as well as 4 CSV files that the script reads. The SAM file containing the SPT configuration and the weather file. 

I really appreciate your help.

Thanks in adavnce.

Mohammed

Hi Mohammed,

This seems to work in SAM 2020.11.29. I tested with the attached modified version of your script.

Dear Mr. Gilman,

I cannot thank you enough for your unlimited support!

It indeed worked and I got the results I need. However I am going to ask for a last favor. The results are written in the CSV file in rows, each 8760 output is split into two rows. Do you propose any possible method in order to output the latter in single columns? 

I am simulating 365 times (that's 365 x 8760 for the outputs). It would be way much easier for me to manage the CSV file if each 8760 outputs were written in a single column. 

Thanks a lot.

Regards,

Hi Mohammed,

My modified script writes a table to CSV using the csvwrite() function. You can have more control over how the data is written to the file by using a different approach. Please see Section 9 of the LK Scripting Reference, which you can find by going to SAM's Help system and clicking "Scripting Reference" at the top of the Help window.

Best regards,
Paul.
