AS compared to transmission lines, it is more important that overhead ground wires or vertical masts over substations be correctly located so as to provide shielding of the structure against direct strokes of lightning. In a previously published paper1 the authors discussed the shielding characteristics required for transmission lines.

IEEE Transactions on Power Delivery, 1989
Conversion of lines and substations to higher voltage has emerged in the industry as a viable alternative in meeting load growth or transmission requirements. This somewhat unconventional approach offers several advantages. Beyond the practical aspects such as use of available right-of-way and substation site, the economic advantages may be of ...

A Platform for Smart Substations
Future Generation Communication and Networking (FGCN 2007), 2007For more efficient and economical management of substations, the concept of a smart substation has been introduced using intelligent and ubiquitous IT techniques. Also, many site studies for smart substations have been performed. In this paper, we propose ubiquitous IT prototype hardware, functions and communication interfaces on an embedded platform ...

Development of a Substation-Area Backup Protective Relay for Smart Substation
IEEE Transactions on Smart Grid, 2017A substation-area protective relay is proposed to overcome the inherent defects of the traditional backup protection system. The relay performs local backup protective functions for the whole substation and its connected transmission lines. The setting coordination of backup protections will be simplified by this relay with a shorter fixed time-delay ...

A novel substation area backup protection for smart substation
2013 IEEE PES Asia-Pacific Power and Energy Engineering Conference (APPEEC), 2013This 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), 2017This 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-to-Substation Applications
2016Power system faults disrupt normal electrical power flow by diverting current through a short-circuited connection and collapsing power system voltage. Prompt and reliable clearing of power system faults therefore is of great importance in the design and operation of the power system.
