Abstract

This paper presents a method to improve the dynamic performance of Thyristor-Controlled Series Capacitor (TCSC) regarding transient stability using remote measurement signals. The remote signals are selected based on their effectiveness for damping the first swings. Phasor Measurement Units are used to measure real-time remote signals and transfer those to the TCSC stability control loop. Transient stability studies are performed for the Vietnamese system, and the benefits of applying TCSCs for the stability enhancement are demonstrated. The case studies show the enhancement of the transient stability comparing control using remote control signals in stead of local signals.
