TCSC, harmonics, firing angle and Loading.


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