HARMONICS AND VOLTAGE STABILITY ANALYSIS IN POWER SYSTEMS USING FACTS BY THYRISTOR-CONTROLLED REACTOR

Abstract

In this study, non-sinusoidal quantities and voltage stability, both known as power quality criteria, are examined together in detail. The widespread use of power electronics elements causes the existence of significant non-sinusoidal quantities in the system. These non-sinusoidal quantities can create serious harmonic distortions in transmission and distribution systems. In this dissertation, harmonic generation of a static VAR compensator with Thyristor-Controlled Reactor and effects of the harmonics on steady-state voltage stability are examined for various operational conditions.
