Adaptive current differential protection schemes for transmission-line protection

IEEE PES General Meeting, 2009
Throughout the history of power system protection, researchers have strived to increase sensitivity and speed of apparatus protection systems without compromising security. With the significant technological advances in wide-area measurement systems, for transmission system protection, current differential protection scheme outscores alternatives like ...

Harmonic-current-restrained relays for differential protection

Electrical Engineering, 1938
DIFFERENTIAL relaying is the commonly accepted means of protecting large power transformers, a-c generators, and station bus systems against internal faults.1 The methods and circuits employed in various instances, while differing in detail, are all fundamentally the same in basic principle.

An Integrated Current Differential Protection Scheme

2006 International Conference on Power System Technology, 2006
This paper presents a new integrated protection scheme for transmission lines. The concept of the integrated protection is firstly introduced, in which a centralized protection system provides the protection of multiple power plant or a substation. A combined integrated protection relay for the protection of double circuit lines is then introduced ...

Modern line current differential protection solutions

2010 63rd Annual Conference for Protective Relay Engineers, 2010
Line current differential protection creates challenges for relay design and application. From a design perspective, the distributed nature of the line current differential system imposes limits on the amount of data that can be exchanged between the system terminals and calls for data alignment schemes to enable the differential protection principle ...

Backup considerations for line current differential protection

2012 65th Annual Conference for Protective Relay Engineers, 2012
Line current differential (87L) protection relies on communications for the exchange of current values and, if applied over asymmetrical channels, on external time sources for current alignment. Proper engineering of 87L schemes calls for a backup strategy that considers the loss of communications and/or the loss of external time sources.
