Short-circuit currents in three-phase a.c. systems - Part 0: Calculation of currents

IEC 60909-0:2016 is applicable to the calculation of short-circuit currents in low-voltage three-phase AC systems, and in high-voltage three-phase AC systems, operating at a nominal frequency of 50 Hz or 60 Hz. It establishes a general, practicable and concise procedure leading to results which are generally of acceptable accuracy and deals with the calculation of short-circuit currents in the case of balanced or unbalanced short circuits. This second edition cancels and replaces the first edition published in 2001. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - contribution of windpower station units to the short-circuit current; - contribution of power station units with ful size converters to the short-circuit current; - new document structure.

Courants de court-circuit dans les réseaux triphasés à courant alternatif - Partie 0: Calcul des courants

L'IEC 60909-0:2016 est applicable au calcul des courants de court-circuit dans les réseaux triphasés basse tension à courant alternatif, et dans les réseaux triphasés haute tension à courant alternatif, fonctionnant à une fréquence nominale de 50 Hz ou de 60 Hz. Elle établit une procédure générale, réalisable et concise conduisant à des résultats qui sont en général d'une précision acceptable. Et traite du calcul des courants de court-circuit dans le cas de courts-circuits symétriques et dissymétriques. Cette deuxième édition annule et remplace la première édition parue en 2001. Cette édition constitue une révision technique. Elle inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: - contribution des groupes de production éoliens au courant de court-circuit; - contribution des groupes de production avec convertisseurs grande capacité au courant de court-circuit; - nouvelle structure du document.

Kratkostični toki v izmeničnih trifaznih sistemih - 0. del: Računanje tokov

Standard IEC 60909-0:2016 se uporablja za izračun kratkostičnih tokov v nizkonapetostnih izmeničnih trifaznih sistemih in visokonapetostnih izmeničnih trifaznih sistemih, ki delujejo pri nominalni frekvenci 50 Hz ali 60 Hz. Uveljavlja splošen, izvedljiv in strnjen postopek z rezultati, ki so običajno sprejemljive natančnosti, ter obravnava izračun kratkostičnih tokov v primeru uravnovešenih in neuravnovešenih kratkih stikov. Druga izdaja razveljavlja in nadomešča prvo izdajo, objavljeno leta 2001. Ta izdaja je tehnično popravljena izdaja. Ta izdaja vključuje naslednje znatne tehnične spremembe glede na prejšnjo izdajo:
– prispevek enot vetrnih elektrarn h kratkostičnemu toku;
– prispevek enot elektrarn s pretvorniki polne velikosti h kratkostičnemu toku;
– nova struktura dokumentov.
