Analysis and Control of Voltage Harmonics Generated by Thyristor Controlled Series Compensator

This paper analyzes the harmonic performance of thyristor controlled series compensators (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 method for adjusting its firing angle such that high line loadability as well as low harmonic generation is achieved. Finally, a TCSC is designed, modeled, simulated and analyzed. The main contribution is consideration of power quality phenomena as well as loadability in the TCSC control scheme.
