Abstract:
This paper presents the impact of three series Flexible AC Transmission System (FACTS) devices, namely the Thyristor Controlled Series Capacitor (TCSC), GTO Controlled Series Capacitor (GCSC) and Thyristor Controlled Series Reactor (TCSR), on the short circuit calculations of a 400 kV electrical transmission line in case of a phase to earth fault in the presence of a fault resistance (RF). The case study is a 400 kV single transmission line in the northern Algerian transmission network which is compensated by each of the three mentioned FACTS devices, consequently. Each compensator is connected at the midpoint of the line to control the reactive power and reactance of the line. The obtained simulations results investigate the impact of the fault resistance, which varies between 0 to 50 Ω, on the parameters of short circuit calculations, without compensation and with each FACTS device. The obtained simulation results match the presented theoretical analysis.
