Re: [TRNSYS-users] Raw weather data

[Dimas Firmanda Al Riza <dimasfirmanda@gmail.com>]

Dear All,

Thankyou for your suggestion Matt and Matthias,
thats very helpful, now I've got another problem,
It is said in the TRNSYS manual that "Type 109 needs two components of solar radiation (e.g. beam and diffuse horizontal) in order to calculate the radiation on a tilted surface."
But I only have one solar radiation component (Direct Beam Horizontal) 
What should I do?

Thanks a lot for your help

Dear Dimas Firmanda Al Riza! 

 

You can also save the file as a *.txt from excel and now you can process the weatherdate directly with TYPE109-User.

The order of the single weather values (temperature, radiation) is described in the haeder of Your weather *.txt.

The rules of the haeder are described in the TRNSYS-manual 5.14.2.5 .

Consider Your file must not have emtpy cells, fill them with "0" (befor exporting to excel), the decimal-seperator must be "." and not "," (likely already Your system-standard).

 

As fas as I know the results of the TYPA109-radiation-processor are said to be better than TAPY16 (this I don't know for sure).

 

Regards,

    Matthias Kersken

Betreff: [TRNSYS-users] Raw weather data

Dear All,

I have raw weather data (in Excel, Temperature, Relative Humidity, Wind Direction, Wind Speed, Solar Radiation),
I want to use it in TRNSYS simulation (standalone PV system), how can I convert that file to standard TMY file that readable by TRNSYS 16?
anybody can help me?
Thanks a lot in advance.
