Distance protection relay performance enhancement through integrated control system

Abstract EN

Enhancement the performance of electrical power system network became essential for
increasing the realiability of power transmission during any disturbance and variations.

One
of these variations is series compensation in heavily loaded transmission lines which affects
directly the Distance Relay (DR) settings.

This paper provides control system architecture to
cover the setting and coordination of protection scheme based on DIgSILENT power factory
program with practical representation of interactive control system by using SIMATIC
manger, and WinCC programs.

Applied scheme makes protection system more reliable with
optimal tripping time.
