Sebastian.stan Posted December 14, 2015 Share Posted December 14, 2015 Hi, I'm trying to use the Measured data analysis tool for comparing the actual production of a PV system to the expected one from the simulation. The comparison is based on five days worth of data (collected by the SCADA system) where the irradiance is at minimum 500 W/m2 for 3 hours. In order to import this data in PVsyst I use the "Import ASCII Hourly file" tool and my file includes the date, hour, measured irradiance on plane and ambient temperature for those 5 days. If I try to import this file I get the error message "This part is suited for comparing measured output data recorded on an existing PV system to simulated results".Fair enough, I add the measured energy injected into grid (E_grid) data to the file and it is imported correctly into PVsyst. Then I move on to the "measured data analysis tool", I use an as-built simulation variant and the measured data I just imported to get a simulation. Now, my understanding is that this simulation will show me the expected energy injected into grid (E_grid) using the meteo data I just imported. But does it do any actual comparison with the measured energy injected into grid I have added to the file?If not, what was the purpose of including the energy injected into grid in the file at the beginning? Please let me know if my understanding is correct and I am using the tools as they are designed? Best Regards,Sebastian Link to comment Share on other sites More sharing options...
