Adjustable speed electrical power drive systems - Part 9-2: Ecodesign for power drive systems, motor starters, power electronics & their driven applications - Energy efficiency indicators for power drive systems and motor starters (IEC 61800-9-2:2017)

IEC 61800-9-2:2017 specifies energy efficiency indicators of power electronics (complete drive modules, CDM), power drive systems (PDS) and motor starters, all used for motor driven equipment. It specifies the methodology for the determination of losses of the complete drive module (CDM), the power drive system (PDS) and the motor system.
It defines IE and IES-classes, their limit values and provides test procedures for the classification of the overall losses of the motor system.
Furthermore, this document proposes a methodology for the implementation of the best energy efficiency solution of drive systems.
This depends on the architecture of the motor driven system, on the speed/load profile and on the operating points over time of the driven equipment.

L'IEC 61800-9-2:2017 spécifie les indicateurs d'efficacité énergétique pour l'électronique de puissance (modules d'entraînement complets, CDM), les entraînements électriques de puissance (PDS) et les démarreurs de moteurs, utilisés avec les équipements entraînés par moteur.
Elle spécifie la méthodologie de détermination des pertes du module d'entraînement complet (CDM), de l'entraînement électrique de puissance (PDS) et du système moteur.
Elle définit les classes IE et IES et établit leurs valeurs limites, ainsi que les procédures d'essai pour le classement des pertes globales du système moteur.
Le présent document propose également une méthodologie pour la mise en œuvre de la meilleure solution écoénergétique des entraînements électriques. Cela dépend de l'architecture du système entraîné par moteur, du profil vitesse/charge et des points de fonctionnement dans le temps de l’équipement entraîné.

Standard IEC 61800-9-2:2017 določa kazalnike energetske učinkovitosti močnostne elektronike (celoviti pogonski moduli, CDM), pogonskih sistemov (PDS) in motornih zaganjalnikov, ki se uporabljajo za opremo na motorni pogon. Določa metodologijo za določanje izgub celovitega pogonskega modula (CDM), pogonskega sistema (PDS) in motornega sistema.
Opredeljuje razrede IE in IES in njihove mejne vrednosti ter navaja preskusne postopke za klasifikacijo skupne izgube motornih sistemov.
Poleg tega ta dokument predlaga metodologijo za uvedbo najboljše rešitve za energijsko učinkovitost pogonskih sistemov.
To je odvisno od arhitekture sistema na motorni pogon, hitrostnega/nalagalnega profila in delovnih točk pogonske opreme.
