Fotonapetostne naprave - 10. del: Metode merjenja linearnosti
Ta del IEC 60904 opisuje postopke, uporabljene za določanje stopnje linearnosti vsakega parametra fotonapetostne naprave v zvezi s preskusnim parametrom. Predvsem je namenjen uporabi v laboratorijih za umerjanje, uporabljajo ga proizvajalci modulov in načrtovalci sistemov. Ocenjevanje fotonapetostnega modula (PV) in delovanja sistema ter prevod delovanja iz enega sklopa temperature in obsevanja v drugega, se pogosto zanaša na uporabo linearnih enačb (glej IEC 60891 in IEC 61829). Ta standard predpisuje linearne zahteve in preskusne metode za zagotavljanje, da bodo te linearne enačbe podale zadovoljive rezultate. Posredno te zahteve narekujejo temperaturni razpon in spremenljivke obsevanja, pri katerih se lahko enačbe uporabljajo. Metode merjenja, opisane v tem standardu, veljajo za vse naprave PV in so namenjene izvajanju na vzorcu ali na primerljivi napravi identične tehnologije. Izvedene morajo biti pred vsemi meritvami in postopki korekcije, ki zahtevajo linearno napravo. Metodologija, uporabljena v tem standardu, je podobna tisti, določeni v IEC 60891, pri kateri je linearna funkcija (ravna črta) priključena sklopu podatkovnih točk, ki uporabljajo rutinska izračunavanja z najmanjšimi kvadrati. Variacija podatkov iz te funkcije je prav tako izračunana, definicija linearnosti pa je izražena kot dopustni odstotek variacije.

Foreword
The text of document 82/582/FDIS, future edition 2 of IEC 60904-10, prepared by IEC TC 82, Solar
photovoltaic energy systems, was submitted to the IEC-CENELEC parallel vote and was approved by
CENELEC as EN 60904-10 on 2010-03-01.
This European Standard supersedes EN 60904-10:1998.
The main technical changes with regard to the EN 60904-10:1998 are as follows:
– Added clause for two-lamp method for Isc linearity.
– Changed standard deviation as a metric for linearity to percent deviation from linearity. This was done
because a non-linear device can have a low standard deviation and percent deviation is the
quantitative number that matters for the parameter of interest.
– Removed clause on spectral responsivity nonlinearity because it is not used by any PV
testing / calibration group. For testing real PV devices it is difficult to make this error significant in the
spectral mismatch correction factor while still passing Isc linearity. Measuring the responsivity over the
entire response range means that the device will probably fail the temperature linearity near the band
edge.
– Added a clause to allow short circuit linearity with temperature or total irradiance to be determined
from absolute spectral responsivity measurements. This data is routinely reported in PTB primary
reference cell calibration certificates.
– Added report clause in compliance with ISO/IEC 17025 requirements.
– Often the temperature coefficient of short circuit current is very small so measurement errors can
result in percent deviations outside the accepted range. Therefore, the following text was added to
7.3c): “If the temperature coefficient of short circuit current is less than 0,1 %/K, then the device can
be considered linear with respect to this parameter.”
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN and CENELEC shall not be held responsible for identifying any or all such patent
rights.
