   Comparison between the ETT and LTT Technologies for Electronic OLTC Transformer Applications
By Juergen SCHIELE, Jens PRZYBILLA, Manex BARRENETXEA INARRA, Ramon LOPEZ-ERAUSKIN [View]
[Download]

Abstract: This paper introduces a novel electronic tap changer application for renewables with light-triggered thyristors for medium-voltage transformers. The on-chip functionality and therobustness of the thyristor support the applications requirements and lower the effort forcontrol and power electronics significantly.

   Multi-time Scale Fault Characteristics of HVDC-Connected Offshore Wind Farm and the Coordination with Different Protection Schemes: A Review
By Guoqing GAO, Frede BLAABJERG, Yanbo WANG [View]
[Download]

Abstract: The high-voltage dc (HVDC)-connected offshore wind farm is a power electronic converter dominated power system. Yet, the highly controlled fault characteristics of converters could affect the efficacy of different protection schemes. This paper first gives an overview of the multi-time scale fault characteristics of converters and the related different protection schemes. Then, the coordinated fast-time scale fault control of converters with the corresponding protection relays is summarized. Lastly, the protection schemes in slow-time scale are investigated, then the modified settings and criteria for these protection schemes are proposed considering the converter fault dynamics.

   System Modelling and Reliability Study of the Tri-Port SST Featuring Energy Storage and Distributed Redundancy for Data Centers
By Daniel SIEMASZKO, Marko MOGOROVIC [View]
[Download]

Abstract: DC powered Data Centers may profit from the proposed Tri-Port SST with UPS for linking MVDC distribution and LVDC bus to IT loads. The solution shows benefits in terms of reliability and efficiency and reduces the number of conversion stages. This work gives demonstrative figures and system level modelling details.
