Photovoltaic system power conversion equipment - Design qualification and type approval
This International Standard lays down IEC requirements for the design qualification of power conversion equipment (PCE) suitable for long-term operation in terrestrial photovoltaic (PV) systems. 1.1 Equipment included in this scope This document covers the following items in its scope: electronic power conversion equipment intended for use in terrestrial PV applications. The term PCE refers to equipment and components for electronic power conversion of electric power into another kind of electric power with respect to voltage, current, and frequency. This standard is suitable for PCE for use in both indoor and outdoor climates as defined in IEC 60721-3-3 and IEC 60721-3-4. Such equipment may include, but is not limited to, grid-tied and off-grid DC-to-AC PCEs, DC-to-DC converters, battery charger converters, and battery charge controllers. This standard covers PCE that is connected to PV arrays that do not nominally exceed a maximum circuit voltage of 1500 V DC. The equipment may also be connected to systems not exceeding 1000 V AC at the AC mains circuits, non-main AC load circuits, and to other DC source or load circuits such as batteries. If particular ancillary parts whereby manufacturers and models are specified in the manual for use with the PCE, then those parts shall be tested with the PCE. 1.2 Equipment for which other requirements may apply This standard has not been written to address characteristics of power sources other than PV systems, such as wind turbines, fuel cells, rotating machine sources, etc. This standard has not been written with the intent of addressing the characteristics of power electronic conversion equipment fully integrated into photovoltaic modules. Separate standards exist or are in development for those types of devices. It is, however, applicable to devices where the manufacturer explicitly specifies the capability of full detachment from and subsequent reattachment to the PV module or if the input and output terminals can be accessed and a specification sheet for the PCE is available. Devices meeting these requirements may be tested as individual samples independent from the PV module. This standard does not apply to power conversion equipment with integrated (built-in) electrochemical energy storage (e.g. lead acid or lithium-ion). It is, however, applicable to equipment where the manufacturer specifies and permits complete removal of the electrochemical energy storage from the PCE so that stand-alone assessment of the PCE with the storage removed becomes possible. 1.3 Object The object of the test sequences contained herein is to establish a basic level of durability and to show, as far as it is possible within reasonable constraints of cost and time, that the PCE is capable of maintaining this performance after prolonged exposure to the simulated environmental stresses described herein that are based on the intended use conditions specified by the manufacturer. Optional tests contained herein may be selected depending on the intended installation, market, or special environmental conditions that the PCE is anticipated to experience. The categorization imposes differentiated test sequences and test severity levels reflecting the different requirements of mechanical and electrical 56 components in different environments. PCE are grouped into categories based on size and installation environment. The actual life expectancy of components so qualified will depend on their design, their environment, and the conditions under which they are operated. Estimation of a lifetime and wear out is not generally covered by this standard.

Le présent document convient pour l’utilisation des PCE dans les conditions climatiques intérieures et extérieures définies dans l’IEC 60721-3-3 et l’IEC 60721-3-4. Un tel matériel peut comprendre, mais sans s’y limiter, les PCE de courant continu à alternatif sur réseau et hors réseau, les convertisseurs continu-continu, les convertisseurs de chargeur de batterie et les contrôleurs de charge de batterie. Le présent document couvre les PCE connectés à des générateurs PV dont la tension nominale ne dépasse pas une tension de circuit maximale de 1 500 V en courant continu. Cette deuxième édition annule et remplace la première édition parue en 2005. Cette édition inclut les modifications techniques majeures suivantes par rapport à l’édition précédente: a. modification du titre; b. cette édition met l’accent sur la qualification de la conception de l’électronique de conversion de puissance (PCE), et élimine les articles et paragraphes associés aux essais de qualification d’autres composants d’équilibrage de système; c. bien que de nombreux titres d’articles et de paragraphes aient été conservés, des modifications significatives ont été apportées; d. la première édition établit les exigences relatives à la qualification de la conception des autres composants d’équilibrage utilisés dans les systèmes photovoltaïques (PV) terrestres, alors que cette édition se limite au matériel de conversion de puissance; e. modification des protocoles d’essai.
Pretvorniki energije za fotonapetostne sisteme - Ocena zasnove in odobritev tipa
Ta mednarodni standard določa zahteve IEC za oceno zasnove pretvornikov energije (PCE), primernih za dolgotrajno uporabo v prizemnih fotonapetostnih (PV) sistemih.
1.1 Oprema, ki spada na to področje uporabe
Področje uporabe tega dokumenta zajema naslednje elemente: elektronski pretvorniki energije, namenjeni za uporabo v prizemnih fotonapetostnih napravah. Izraz »pretvorniki energije« se navezuje na opremo in sestavne dele za elektronsko močnostno pretvorbo električne energije v drugo vrsto električne energije glede na napetost, tok in frekvenco. Ta standard je primeren za pretvornike energije, ki se uporabljajo v notranjem in zunanjem okolju, kot je opredeljeno v standardih IEC 60721-3-3 in IEC 60721-3-4. Taka oprema lahko med drugim vključuje pretvornike energije za pretvorbo enosmernega toka v izmenični tok, ki se uporabljajo znotraj in zunaj omrežja, pretvornike enosmernega toka v enosmerni tok, pretvornike za napajalnike baterij in naprave za nadzor napolnjenosti baterij.
Ta standard zajema pretvornike energije, priključene na fotonapetostne sisteme, katerih nominalna vrednost ne presega največje napetosti tokokroga 1500 V DC. Oprema se lahko priključi tudi na sisteme, ki ne presegajo 1000 V AC v omrežnem tokokrogu z izmeničnim tokom, neomrežne obremenitvene tokokroge z izmeničnim tokom in druge tokokroge z virom enosmernega toka oz. obremenitvene tokokroge (npr. baterije). Če so za uporabo s pretvorniki energije v priročniku navedeni določeni pomožni deli (vključno s proizvajalci in modeli), je treba te dele preskusiti s pretvorniki energije.
1.2 Oprema, za katero morda veljajo druge zahteve
Ta standard ni namenjen obravnavi značilnosti virov napajanja, ki niso fotonapetostni sistemi (npr. vetrne turbine, gorivne celice, viri rotacijskih strojev itd.).
Ta standard ni namenjen obravnavi značilnosti elektronskih pretvornikov energije, ki so v celoti vgrajeni v fotonapetostne module. Za te vrste naprav obstajajo oziroma so v pripravi ločeni standardi. Vendar pa se uporablja za naprave, pri katerih proizvajalec izrecno navede, da jih je mogoče v celoti odklopiti s fotonapetostnega modula in jih nato znova priklopiti, ali če je mogoče dostopati do vhodnih in izhodnih terminalov in je na voljo specifikacija za pretvornik energije. Naprave, ki izpolnjujejo te zahteve, se lahko preskusi kot posamezne vzorce, neodvisne od fotonapetostnega modula.
Ta standard se ne uporablja za pretvornike energije z integriranim (vgrajenim) elektrokemičnim shranjevanjem energije (npr. svinčeno-kislinske ali litij-ionske baterije). Vendar pa se uporablja za pretvornike, pri katerih proizvajalec navede in dovoljuje popolno odstranitev elektrokemičnega shranjevanja energije iz pretvornika energije, tako da je mogoče izvesti samostojno oceno pretvornika.
1.3 Namen
Namen zaporedij preskusov iz tega dokumenta je vzpostaviti osnovno raven trajnosti in prikazati (kot je mogoče v razumnih stroškovnih in časovnih omejitvah), da lahko pretvornik energije ohrani to zmogljivost po dolgotrajnejši izpostavljenosti simuliranim okoljskim obremenitvam, opisanim v tem dokumentu, ki temeljijo na pogojih predvidene uporabe, ki jih določi proizvajalec. Neobvezni preskusi iz tega dokumenta se lahko izberejo glede na predvideno namestitev, tržišče ali posebne okoljske pogoje, ki naj bi jim bil pretvornik energije izpostavljen. Kategorizacija zahteva raznolika zaporedja preskusov in stopnje zahtevnosti preskusa,
ki odražajo različne zahteve mehanskih in električnih sestavnih delov v različnih okoljih.
Pretvorniki energije so razvrščeni v kategorije glede na velikost in okolje namestitve.
Dejanska pričakovana življenjska doba tako kvalificiranih sestavnih delov je odvisna od njihove zasnove, okolja uporabe in pogojev delovanja. Ocena življenjske dobe in obrabe na splošno ni zajeta v tem standardu.
