Abstract: This paper focuses on innovative dynamic performance of power electronics based on generalised unified power flow controller (PFC). The GUPFC is a voltage source converter (VSC) based flexible AC transmission system (FACTS) controller used to provide series and shunt compensation among the multi transmission line systems of a substation. GUPFC improves the performance of power quality issues, active and reactive power oscillations in multiple transmission lines. This paper proposes a complete replica comprising of 48-pulse gate turn-off (GTO) thyristor based VSC which examines the dynamic operation of control scheme for shunt and two series VSC for voltage stabilisation and active and reactive power compensation by using POD controller among the transmission lines of the grid network. It is able to control injected voltage, at the same time as keeping injected voltage in quadrature with current within the power system is completely modelled in MATLAB/SIMULINK.
Keywords: 48-pulse; generalised unified power flow controller; GUPFC; power oscillation damping; POD; power quality.
