Enhancing the performance of distance protection relays using interactive control system

Abstract

Recently improvement of automation systems for electrical power system network became essential for increasing the realiability of power transmission during any disturbance. In a substations the setting of Distance Relays (DRs) are set manually which depends on human experience which may be led to undesirable operation. Any power transmission system may subjected to shortens and loss of adjusting its protection setting, DRs in protection systems are responsible for protected a High voltage transmission lines from short circuit, power swing, and load encroachment, A proposes automation system architecture is introduced to cover the setting and coordination of protection scheme based on DIgSILENT power factory, SIMATIC manger, and WinCC programs.

Experimental platform tests for setting performances of distance protection installed in Biskra-Batna of the Algerian transmission line

“…The performance of the proposed numerical algorithm is validated on tested on simulated transmission line of Merowe-Atbara 500 KV, 50 Hz, and 236.7 KM using data generated by PSCAD/EMTDC. To increase the relaibility of transmission power system, authors in [10], proposed an interactive control strategy to improve the setting and coordination of distance relays. In [11], nonlinear multivariable optimization techniques have been used to improve the performance of distance relays in coordination with directional overcurrent.…”
