“…These schemes have limitation to detect unsymmetrical fault existing during power swing. In [10], a fault detecting methodology by implementing superimposed component of current is put forward. But the defined technique fails when a three-phase fault happens along with a slow power swing.…”

Digital distance relaying is implemented in extra high voltage (EHV) transmission network for speedy and reliable fault detection. But it should not activate in case of slow transients known as power swings. However, for occurrence of any type of fault during power swing, the relay should sense the faulty condition and send trip command to concerned circuit breaker. The detection of fault in a transmission line network with TCSC during the power swing condition has become further complex due to transients generated by series capacitor and the metal–oxide varistor (MOV) protecting it. This paper firstly presents effect of TCSC on distance relay operation for varied TCSC degree of compensation and firing angle values. Further, a discrete wavelet transform-based fast acting fault and swing classification algorithm is proposed which can sense all types of faults during slow as well as fast power swing in first decomposition level and within 0.001 sec. The proposed utilizes optimized threshold values both for swing and fault sensing by using Honey Bee Optimization Algorithm (HBOA). The proposed novel algorithm is coded in MATLAB software and the test system comprising of 400kV, 50Hz parallel transmission line network along with TCSC is built using MATLAB Simulink environment with sim power systems toolbox. It is tested for high/low resistance faults, symmetrical/asymmetrical faults and close-in/far end faults by changing TCSC compensation level and firing angle value. The simulation results prove the accuracy of proposed methodology for swing and fault classification.

“…There are articles focus on the problem of the over reach in series compensated transmission lines use [16]. A new digital distance relaying algorithm for firstzone protection for series compensated double-circuit transmission lines and a new method uses data from one end of the protected double-circuit lines to calculate the fault distance are illustrated in [17].…”

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.
