Item Flexible prototype of modular multilevel converters for experimental verification of DC transmission and multiterminal systems(Institute of Electrical and Electronics Engineers Inc., 2017-12-05) Konstantinou, Georgios; Ceballos, Salvador; Gabiola, Igor; Pou, Josep; Karanayil, Baburaj; Agelidis, Vassilios G.; POWER ELECTRONICS AND SYSTEM EQUIPMENTTesting and verification of high-level and low-level control, modulation, fault handling and converter co-ordination for modular multilevel converters (MMCs) requires development of experimental prototype converters. In this paper, we provide a a complete overview of the MMC-based experimental prototype at UNSW Sydney (The University of New South Wales) including the structure of the sub-modules, communication, control and protection functions as well as the possible configurations of the system. The prototype, rated at a dc voltage of up to 800 V and power of 20 kVA and can be used to study the operation of a single converter, back-to-back and point-to-point connections as well as multi-terminal systems.
