Anotation

Describes method for calculating short-circuit currents in d.c. auxilliary systems in power plants and substations, which can be equipped with the following equipment, acting as short-circuit current sources: - rectifiers in three-phase a.c. bridge connection for 50 Hz; - stationary lead-acid batteries; - smoothing capacitors; - d.c. motors with independent excitation Provides a generally applicable method of calculation which produces results of sufficient accuracy on the conservative side. The contents of the corrigenda of February 1999 and March 2000 have been included in this copy. Decrit une methode de calcul des courants de court-circuit des reseaux auxiliaires en courant continu dans des centrales et des postes, qui peuvent etre equipes des elements suivants, agissant comme sources de courants de court-circuit: - redresseurs dans les ponts triphases en courant alternatif pour 50 Hz; - batteries stationnaires au plomb; - condensateurs de lissage; - moteurs a courant continu avec excitation independante. Fournit une methode generale de calcul donnant des resultats suffisamment precis et par exces. Le contenu des corrigenda de fevrier 1999 et mars 2000 a ete pris en consideration dans cet exemplaire.
