Thematic Series on Fault analysis and relay protection for grids powered through converters
Guest Editor-in-Chief: Guobin Song, Qinghua Wu
The main material of power equipment has been transitioning from ferromagnetic materials to power semiconductors over the last few decades. By now, a lot of power semiconductor-based equipment have been widely applied in the generation, transmission, distribution and consumption of the electricity. Such wide applications of the power semiconductor-based equipment are motivated by their superior performance in terms of, e.g., safety, quality and cost, which are desired by the power plant owners, transmission owners, utilities and customers.
Converters, in power equipment, are serving as sources supplying powers to the connected grids. The converter-interfaced generations are and will be more and more popular in the modern power systems, e.g. renewable integration systems excited by inverters, DC transmission lines/grids excited by rectifiers and DC receiving end system excited by inverters. A deep understanding of these converters’ responses to different faults will play an important role in the reliable fault detection such that the safe operation of the grid can be ensured.
This special issue aims to publish original research papers and reviews on the technologies, algorithms, strategies, platform and case studies related to relay protections of grids powered through converters.
Topics of interest include but are not limited to:
1. Simplified modeling of power systems with large scale converters
2. Analysis and characterization of converter-powered systems under fault conditions
3. Adaptability analysis of existing protection principles in converter-powered systems
4. New protection principles and schemes for systems powered through converters
5. Reclosing / restarting of AC / DC converter-based power grids
6. Integration of control and protection
All papers and supplementary information (if any) should be submitted online and prepared according to PCMP guidelines. Authors should indicate that the paper is submitted for the thematic series in their cover letter and is not published or being considered to be published elsewhere. All submission will be subject to peer review before possible acceptance for publication in PCMP which is free of charge and highly accessed by readers from all over the world.
