Weather file input into SAM

Hi Paul,

I have a weather file with measurements (Year,Month,Day,Hour,Beam,Tdry,RH,Pres,Wspd) that works in the parabolic trough model (with a lot of warnings) but not in the empirical trough model, which is the one that I need, since it stops at error.

I don't know where the problem lies, but could it be related with the column variables I'm using? SAM calculates Tdew through Tdry and RH but maybe I have misplaced them! Could you please help me with this? I've attached here the .csv file!

Thank you very much for the attention!

Best regards,

Scheffler dish

Can we model a scheffler dish using SAM? if yes how?
thanks in advance.

Power Block 500 MW to 1000 MW and above equipment

Dear SAM Users;

I have been researching on very large CSP power plants (1000 MW and above) for a long while.

Please find some of my research studies related to it on my researcher's profiles.

How does the approach temperature of cooling water affect the power cycle efficiency of CSP plant?

Hello. I've been try to understand how the approach temperature of cooling water affects the power cycle conversion efficiency of a hypothetical wet-cooled parabolic-trough CSP plant located in Mojave, Californa. The attached figure shows the yearly average efficiency as a function of the approach temperature. My question is why T_approach = 10C has the highest efficiency instead of T_approach = 5C. Thank you.

how do import data from excel to SAM? i tried converting the excel sheet to csv but i keep getting errors, only then i realized the headings are not the same with the inbuilt csvs that are in the source folder.

and if there is anyone out here who is good, kindly email me @:
attached is my data for one month and the rest are similar for 2017 & 2016

thank you

KW scale PT

I was wondering if I can simulate Kw scale parabolic trough in SAM. and if yes, how?

Thank you,

configuration of storage tank and backup fossil fuel for heat process parabolic

I am currently trying to perform simulations of parabolic channel concentrators for industrial heat. However, I have some doubts about the operation of the software:

1.- Is it possible to limit the number of hours of operation avoiding that the storage system discharges all the energy immediately and keep it for very cloudy days?

2.- Is it possible to simulate using a support heating system in series and not in parallel?

I appreciate your response in advance. Greetings.

Parabolic Trough Tilt

Hi there, I live in a northern latitude in Canada. When I run the Parabolic Trough model and include some tilt I see less heat output from the field, providing I enter positive values - ie closer to vertical. But when I tilt the trough downward with negative values, like -10 deg the trough output goes up quite a bit. Am I getting valid results? Thanks Allan
