Shielding of substations

Electrical Engineering, 1942
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.

Substation voltage upgrading

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), 2007
For 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, 2017
A 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 ...

Substation-to-Substation Applications

2016
Power 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.
