Distance Protection by Digital Technique

IFAC Proceedings Volumes, 1977
Abstract This paper presents a method of distance protection by digital technique. The characteristic of mho and reactance relay is realized by the performance equation. Some performance equations are derived by different methods. One is derived from a torque equation, and other is from the vector relation, Their superiority or inferiority is ...

Error insensitive distance protection

European Transactions on Electrical Power, 1992
AbstractThis paper shows that no algorithm exists so far with an optimal behaviour to all non‐ideal input signals. Furthermore, it is not possible to combine an algorithm solving differential equations and a filtering algorithm to achieve an error insensitive behaviour. However, the combination of different algorithms results in an improved behaviour.

Distance protection of teed circuits

Proceedings of the Institution of Electrical Engineers, 1967
Multiended network interconnections, such as teed circuits, invariably pose special difficulties in their protection, and the methods of relaying that have been widely applied to plain feeders are often of limited applicability to circuits having more than two ends within the protected zone.

Feeder protection: distance systems

1995
The principle of impedance measurement and the engineering of basic impedance measuring elements into schemes of distance protection whether they be switched, nonswitched, carrier-aided etc., has always formed a very important part of power system feeder protection.
