This Task Force paper presents several important aspects on modelling single-phase power electronic converters (PECs) for power system distortion studies in the 2-150 kHz frequency range (also referred to as supraharmonics). The paper summarizes the state of the art and provides a systematic framework for the development of models of the unintentional emissions produced by modern PECs in this frequency range. Starting from a review of the basic concepts of the phenomena, model requirements, functionality and validation procedures are defined. The main modelling approaches proposed for power system distortion studies in the 2-150 kHz frequency range are discussed and compared. A detailed numerical case study of a fixed switching frequency converter is included to illustrate and compare the application and performance of different models.

Abstract
This Task Force paper presents several important aspects on modelling single-phase power electronic converters (PECs) for power system distortion studies in the 2-150 kHz frequency range (also referred to as supraharmonics). The paper summarizes the state of the art and provides a systematic framework for the development of models of the unintentional emissions produced by modern PECs in this frequency range. Starting from a review of the basic concepts of the phenomena, model requirements, functionality and validation procedures are defined. The main modelling approaches proposed for power system distortion studies in the 2-150 kHz frequency range are discussed and compared. A detailed numerical case study of a fixed switching frequency converter is included to illustrate and compare the application and performance of different models.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
