Annotation of standard text IEC 62751-2-ed.1.0 :
IEC 62751-2:2014 gives the detailed method to be adopted for calculating the power losses in the valves for an HVDC system based on the "modular multi-level converter", where each valve in the converter consists of a number of self-contained, two-terminal controllable voltage sources connected in series. It is applicable both for the cases where each modular cell uses only a single turn-off semiconductor device in each switch position, and the case where each switch position consists of a number of turn-off semiconductor devices in series (topology also referred to as "cascaded two-level converter"). The main formulae are given for the two-level "half-bridge" configuration but guidance is also given as to how to extend the results to certain other types of MMC building block configuration. LIEC 62571-2:2014 donne la methode detaillee a adopter pour calculer les pertes de puissance dans les valves dun systeme CCHT dote dun "convertisseur multiniveaux modulaire" dont chaque valve est composee dun certain nombre de sources de tension independantes commandables a deux bornes connectees en serie. Elle sapplique lorsque chaque cellule modulaire nutilise quun seul dispositif a semi-conducteur blocable dans chaque position de commutation, et lorsque chaque position de commutation est composee dun certain nombre de dispositifs a semi-conducteur blocables en serie (cette topologie etant egalement appelee "convertisseur a deux niveaux monte en cascade"). Les principales formules sont donnees pour la configuration "en demi-pont" a deux niveaux. Des lignes directrices sont egalement donnees pour indiquer letendue des resultats de certains autres types de configurations de bloc module MMC.
