A novel substation area backup protection for smart substation

2013 IEEE PES Asia-Pacific Power and Energy Engineering Conference (APPEEC), 2013
This paper proposes a new scheme of substation area backup protection system based on substation area range of information. A configuration scheme of relay protection in smart substation was proposed firstly, the structure of substation area backup protection (SABP) was introduced, the information matrix of SABP which can reflect the substation ...

An optimized design of substation-area protection in smart substation

2017 IEEE 3rd Information Technology and Mechatronics Engineering Conference (ITOEC), 2017
This paper proposes a substation-area protection in smart substation to overcome the defects in conventional protection system. The protection can provide local backup protection for the whole substation with current differential principle. The current sampled values are obtained by process level Ethernet inside smart substation, also by wide-area ...

Substation earthing: special considerations for GIS substations

IEE Seminar on Substation Earthing - Shedding Light on the Black Art, 2000
The use of compressed SF/sub 6/ as an insulating medium has led to the development of compact gas-insulated substation (GIS) technology. GIS, having many advantages over conventional air-insulated substations (AIS), have been receiving wide application. However, this alternate technology has inevitably lead to a different set of problems to resolve. In

Study on the Substation Area Backup Protection in Smart Substation

2012 Asia-Pacific Power and Energy Engineering Conference, 2012
Since the interactivity, integrality and instantaneity of the data communication in smart substation have been improved to a higher degree, it can contribute to the construction and realization of substation area backup protection (SABP). In this paper, the structure and characteristics of smart substation were introduced firstly, and the application ...
