Annotation of standard text IEC/TS 62578-ed.2.0 :

IEC TS 62578:2015 describes the operation conditions and typical characteristics of active infeed converters (AIC) of all technologies and topologies which can be connected between the electrical power supply network (lines) a.c. side and a constant current or voltage type d.c. side and which can convert electrical power (active and reactive) in both directions (generative or regenerative). The following is excluded from the scope: - Requirements for the design, development or further functionality of active infeed applications. - Probability of interactions or influences of the AIC with other equipment caused by parasitic elements in an installation or caused by poor electronic design as well as their mitigations. - "Overhead line" power supply networks because of lack of information (measurements) of their three phase impedances. This edition includes the following significant technical changes with respect to the previous edition: a) IEC TS 62578, in its revised version includes observed values out of practical applications for emission values below 150 kHz. b) Therefore the document has been extended compared to the first edition, several detailed analysis results are given in the extended Annexes. c) Design recommendations have been derived from the international working group by an assessment of the power supply impedances between 2 kHz and 9 kHz, a comprehensive analysis of the withstand capability of power capacitors against harmonic currents injected by AIC, immunity tests of equipment and considerations about shifted resonances in the power supply network with increased population of undamped filter capacitors. LIEC TS 62578:2015 decrit les conditions de fonctionnement et les caracteristiques typiques des convertisseurs a alimentation active (AIC), quelles que soient leurs technologies et topologies, qui peuvent etre connectes entre le reseau (les phases) dalimentation electrique cote alternatif et un type de courant ou de tension constant(e) cote continu, et qui peuvent convertir la puissance electrique (active et reactive) dans les deux directions (generatrice ou regeneratrice). Les aspects suivants sont exclus du domaine dapplication: - Les exigences de conception, de developpement ou autres fonctionnalites des applications a alimentation active. - La probabilite dinteractions ou dinfluences de lAIC avec dautres equipements generees par des elements parasites dans une installation ou par une conception electronique peu avancee, ainsi que leurs limitations. - Les reseaux dalimentation par "ligne aerienne", en raison du manque dinformations (mesures) relatives a leurs impedances triphasees. Cette edition inclut les modifications techniques majeures suivantes par rapport a ledition precedente: a) LIEC TS 62578, dans sa version revisee, inclut les valeurs observees hors des applications pratiques pour les valeurs demission inferieures a 150 kHz. b) Par consequent, le document a ete developpe compare a la premiere edition, plusieurs resultats danalyse detaillee etant donnes dans les Annexes etendues. c) Les recommandations de conception ont ete etablies par le groupe de travail international suite a une evaluation des impedances dalimentation comprises entre 2 kHz et 9 kHz, a une analyse approfondie de la capacite de tenue des condensateurs de puissance par rapport aux courants harmoniques injectes par lAIC, a des essais dimmunite de lequipement et a des considerations relatives aux resonances decalees dans le reseau dalimentation avec laugmentation de la population des condensateurs de filtrage sans amortissement.
