(Main)Overall efficiency of grid connected photovoltaic inverters
Overall efficiency of grid connected photovoltaic inverters
This European Standard provides a procedure for the measurement of the efficiency of the maximum power point tracking (MPPT) of inverters, which are used in grid-connected photovoltaic systems. In that case the inverter energizes a low voltage grid with rated AC voltage and rated frequency. Both the static and dynamic MPPT efficiency is considered. Based on the static MPPT efficiency and conversion efficiency the overall inverter efficiency is calculated. The dynamic MPPT efficiency is indicated separately.
Gesamtwirkungsgrad von Photovoltaik-Wechselrichtern
Efficacité globale des onduleurs photovoltaïques raccordés au réseau
La présente Norme Européenne fournit une procédure de mesure de l’efficacité de la conversion optimale d’énergie (MPPT – Maximum Power Point Tracking en anglais) des onduleurs, qui sont utilisés dans des systèmes photovoltaïques raccordés au réseau. Dans ce cas, l'onduleur alimente un réseau basse tension avec une tension alternative assignée et une fréquence assignée. L'efficacité de la MPPT tant statique que dynamique est prise en considération. L'efficacité globale de l'onduleur est calculée en fonction de l'efficacité de la MPPT statique et de l'efficacité de la conversion. L'efficacité de la MPPT dynamique est indiquée séparément.
Celovita učinkovitost fotonapetostnih razsmernikov
Ta evropski standard zagotavlja postopek za merjenje učinkovitosti sledenja maksimalni moči (MPPT) razsmernikov, ki se uporabljajo v omrežju povezanih fotonapetostnih sistemov. V tem primeru razsmernik napaja nizkonapetostno omrežje z nazivno izmenično napetostjo in nazivno frekvenco. Upoštevani sta statična in dinamična učinkovitost MPPT. Na osnovi statične učinkovitosti MPPT in učinkovitosti pretvorbe se izračuna celovita učinkovitost razsmernika. Dinamična učinkovitost MPPT je prikazana ločeno.
