Distance Protection Scheme for a Digital Substation

2020 IEEE International Conference on Automation, Quality and Testing, Robotics (AQTR), 2020
The protection system in a digital substation is of high importance in the context of larger and larger interconnected power systems. The IEC61850 standard enables easier operation of protection and control in substations. A special case of the distance protection scheme for a 220kV overhead line- autotransformer block in the Romanian Power System is ...

Fundamentals of Distance Protection

2008 61st Annual Conference for Protective Relay Engineers, 2008
In this paper we have reviewed some basic principles of distance protection. This includes fundamentals of measuring distance to fault based on electrical signals from one end of the circuit; the principles of amplitude and phase comparators to implement a distance relay; and various technologies used to build distance relays.

Transients in distance protection

Proceedings of the Institution of Electrical Engineers, 1963
The demand for high-speed operation in distance protection involves design consideration under three main headings, namely: the transient primary current and voltage at the relaying point; the modification of these signals due to secondary circuits; and the effect of the modified secondary signals on two input comparators currently or prospectively ...
