10.22099/ijste.2006.866

Abstract

This paper analyzes the harmonic performance of thyristor controlled series capacitors (TCSCs) in power systems and proposes an effective method for their control and limitation in the compensated line. This is performed by proper selection of TCSC elements (capacitance and inductance) and by introducing a new method for adjusting its firing angle such that high line loadability as well as low harmonics generation is achieved. Finally, a TCSC is designed, modeled, simulated and analyzed. The main contribution is the consideration of power quality phenomena, as well as loadability in the TCSC control scheme.
