Uninterruptible power systems (UPS) - Part 3: Method of specifying the performance and test requirements

IEC 62040-3:2011 applies to movable, stationary and fixed electronic uninterruptible power systems (UPS) that deliver single or three phase fixed frequency a.c. output voltage not exceeding 1 000 V a.c. and that incorporate an energy storage system, generally connected through a d.c. link. This standard is intended to specify performance and test requirements of a complete UPS and not of individual UPS functional units. The individual UPS functional units are dealt with in IEC publications referred to in the bibliography that apply so far that they are not in contradiction with this standard. The primary function of the UPS covered by this standard is to ensure continuity of an a.c. power source. The UPS may also serve to improve the quality of the power source by keeping it within specified characteristics. UPS have been developed over a wide range of power, from less than hundred watts to several megawatts, to meet requirements for availability and quality of power to a variety of loads. Refer to Annexes A and B for information on typical UPS configurations and topologies. This standard also covers UPS test and performance when power switches form integral part of a UPS and are associated with its output. Included are interrupters, bypass switches, isolating switches, and tie switches. These switches interact with other functional units of the UPS to maintain continuity of load power. This standard does not cover: - conventional a.c. input and output distribution boards or d.c. boards and their associated switches (e.g. switches for batteries, rectifier output or inverter input); - stand-alone static transfer systems covered by IEC 62310-3; - systems wherein the output voltage is derived from a rotating machine. NOTE 1 This standard recognises that power availability to information technology (IT) equipment represents a major UPS application. The UPS output characteristics specified in this standard are therefore also aimed at ensuring compatibility with the requirements of IT equipment. This, subject any limitation stated in the manufacturer's declaration, includes requirements for steady state and transient voltage variation as well as for the supply of both linear and non-linear load characteristics of IT equipment. NOTE 2 Test loads specified in this standard simulate both linear and non-linear load characteristics. Their use is prescribed with the objective of verifying design and performance, as declared by the manufacturer, and also of minimising any complexity and energy consumption during the tests. NOTE 3 This standard is aimed at 50 Hz and 60 Hz applications but does not exclude other frequency applications within the domain of IEC 60196. This is subject to an agreement between manufacturer and purchase in respect to any particular requirements arising. NOTE 4 Single phase and three-phase voltage UPS covered by this standard include without limitation UPS supplying single-phase, two-wire; single-phase, three-wire; two-phase, three-wire, three-phase, three-wire and three-phase, four-wire loads. This second edition cancels and replaces first edition published in 1999 and constitutes a technical revision. The significant technical changes are: - reference test load - definition and application revised (3.3.5 and 6.1.1.3); - test schedule - presented as a single table grouped by revised type and routine tests (see 6.1.6, Table 3); - dynamic output voltage performance characteristics - guidance to measure - addition (Annex H); - UPS efficiency - requirements and methods of measure - addition (Annexes I and J); - functional availa

Alimentations sans interruption (ASI) - Partie 3: Méthode de spécification des performances et exigences d'essais

La CEI 62040-3:2011 s'applique aux systèmes d'alimentation sans interruption (ASI) électroniques mobiles, immobiles et fixes, qui délivrent une tension de sortie alternative à fréquence fixe mono- ou triphasée ne dépassant pas 1 000 V en courant alternatif et qui possèdent un moyen d'accumulation d'énergie généralement connecté via une liaison à courant continu. La présente norme vise à spécifier les performances et les exigences d'essai d'une ASI complète et non des unités fonctionnelles d'ASI individuelles. Les unités fonctionnelles d'ASI individuelles sont traitées dans des publications CEI auxquelles il est fait référence dans la bibliographie, lesquelles s'appliquent dans la mesure où elles ne sont pas en contradiction avec la présente norme. La fonction essentielle de l'alimentation sans interruption (ASI) couverte par la présente norme est d'assurer la permanence d'une source d'alimentation alternative. L'alimentation sans interruption peut aussi servir à améliorer la qualité de la source d'alimentation en la maintenant dans les limites des caractéristiques spécifiées. Toutes sortes d'alimentations sans interruption ont été développées pour satisfaire aux exigences par rapport à la permanence et à la qualité de l'alimentation de différents types de charges dans une large gamme de puissance de moins de cent watts à plusieurs mégawatts. Se reporter aux Annexes A et B pour avoir des informations sur les configurations et topologies types des ASI. Cette norme concerne également les essais et performances d'ASI quand des interrupteurs de puissance font partie intégrante d'une ASI et sont associés à sa sortie. Elle inclut les interrupteurs, les interrupteurs de bypass, les interrupteurs d'isolement et les interrupteurs de liaison. Ces interrupteurs réagissent avec d'autres unités fonctionnelles de l'ASI pour maintenir la continuité de l'alimentation de la charge. La présente norme ne couvre pas: - les tableaux de distribution conventionnels à entrée et sortie alternatives ou les tableaux en continu et leurs interrupteurs associés (par exemple les interrupteurs pour batteries, pour la sortie du redresseur ou pour l'entrée de l'onduleur); - les systèmes de transfert statique autonomes couverts par la CEI 62310-3; - les systèmes dont la tension de sortie est dérivée d'une machine tournante. NOTE 1 Cette norme reconnaît que la disponibilité de l'alimentation pour les matériels de traitement de l'information (IT) représente une application majeure des ASI. Les caractéristiques de sortie de l'ASI spécifiées dans la présente norme ont donc également pour but de garantir la compatibilité avec les exigences des matériels d'IT. Celle-ci, soumise à toute limitation indiquée dans la déclaration du fabricant, comporte des exigences relatives aux variations de tension en régime établi et transitoire ainsi qu'à l'alimentation des caractéristiques de charge à la fois linéaires et non linéaires des matériels d'IT. NOTE 2 Les charges d'essai spécifiées dans la présente norme simulent les caractéristiques de charge à la fois linéaires et non linéaires. Leur usage est prescrit avec pour objectif de vérifier la conception et la performance déclarées par le fabricant, ainsi que de limiter toute complexité et consommation d'énergie pendant les essais. NOTE 3 La présente norme vise les applications à 50 Hz et à 60 Hz mais n'exclut pas les applications à d'autres fréquences dans le domaine de la CEI 60196. Cela est soumis à un accord entre le fabricant et l'achete

Sistemi z neprekinjenim napajanjem - 3. del: Metoda za določanje lastnosti in preskusnih zahtev

Ta mednarodni standard velja za premične, mirujoče ali pritrjene elektronske sisteme z neprekinjenim napajanjem (UPS), ki dovajajo eno- ali trifazno izhodno napetost izmeničnega toka fiksne frekvence, ki ne presega 1000 V izmeničnega toka, in vsebujejo sistem za hranjenje energije, običajno povezan skozi člen z enosmernim tokom. Ta standard se uporablja za določanje delovnih in preskusnih zahtev celotnega UPS in ne posameznih delujočih enot UPS. Posamezne funkcijske enote UPS obravnavajo objave IEC, navedene v bibliografiji, in veljajo, dokler ne nasprotujejo temu standardu. Glavna funkcija UPS, zajetih v tem standardu, je zagotoviti neprekinjenost vira energije izmeničnega toka. UPS se lahko uporablja tudi za izboljšanje kakovosti vira energije, tako da ga vzdržuje v okviru nekaterih lastnosti. UPS so bili razviti v širokem razponu moči, od manj kot 100 vatov do več megavatov, da izpolnjujejo zahteve za razpoložljivost in kakovost energije pri različnih obremenitvah. V dodatku A in B si preberite informacije o tipičnih konfiguracijah in topologijah UPS. Ta standard prav tako zajema preskus in delovanje UPS, kadar stikala tvorijo sestavni del UPS in so povezana z njegovim izhodom. Vključeni so prekinjevalniki, premostitvena stikala, ločilniki in zvezna stikala. Ta stikala medsebojno sodelujejo z drugimi delujočimi enotami UPS in vzdržujejo neprekinjenost napajanja.
