Converter-based DC Distribution System Protection

2018 IEEE Industry Applications Society Annual Meeting (IAS), 2018
Dc distribution systems are being widely adopted in many industrial, commercial and military energy systems such as commercial buildings, data centers, off-shore wind farms, and shipboard power systems. A dc distribution system can improve energy efficiency and reduce the size or weight of power systems.

Protection for distributed generations in the DC micro-grid

2011 2nd IEEE PES International Conference and Exhibition on Innovative Smart Grid Technologies, 2011
In this paper, an analysis results for the protection of a DC micro-grid is described. The 400V DC micro-grid consists of a wind power system (Permanent Magnet Synchronous Generator, PMSG), a photo-voltaic system, a fuel cell system and energy storages. Abnormal operating conditions during various faults are studied. According to a series of studies, a

Structuring, Controlling and Protecting the DC Grid

2020 International Symposium on Electronics and Telecommunications (ISETC), 2020
The structure of a DC grid enables control and protection in a different way, as usually employed in AC grids. Power electronic converters combine the control and protection. The structure of the DC grid is also determined by the type of power electronic converters being centralized or decentralized.

Implementation of control and protection logics for a bidirectional DC/DC converter

2010 IEEE International Symposium on Industrial Electronics, 2010
In this paper, a control strategy for a bidirectional DC/DC power converter is discussed, and the logics to guarantee the operation correctness in various operative modes and for safety requirements are considered. In Buck (or step- down) mode, a voltage PI regulator is proposed, whereas in Boost (or step-up) mode an inner current control loop is ...

Protection of DC and hybrid AC-DC microgrids with ring configuration

2017 7th International Conference on Power Systems (ICPS), 2017
This paper presents protection techniques for DC and hybrid AC-DC microgrids. The DC microgrid protection is proposed based on difference of transient energy at both ends of the line to be protected using voltage and current measurements. Method can identify the fault is either internal or external.

DC overcurrent protection-Where we stand

Conference Record of the 1992 IEEE Industry Applications Society Annual Meeting, 1993
The procedures used to determine the DC ratings for fuses and the issues pertinent to ensuring a proper DC fuse application are discussed. For a better understanding of how fuses are rated for DC, Underwriters Laboratories UL Standard 198L is examined.

Topologically Protected DC–DC Converters.pdf

This research paper explores the design and analysis of topologically protected DC–DC converters, integrating concepts from topological physics to enhance power conversion performance. Conventional power converters often suffer from noise susceptibility, component variations, and limited stability under transient conditions. By leveraging a topological
