Abstract :
The paper investigates the impact of using Static Synchronous Series Compensator (SSSC) in phase imbalanced operation modes on damping subsynchronous resonance in series capacitive compensated transmission grid. Phase imbalance has the potential of reducing the energy exchange between the electrical and mechanical sides of the turbine-generator and, therefore, damps subsynchronous oscillations. The validity and effectiveness of different proposed phase imbalanced modes have been demonstrated on the IEEE first benchmark model by means of time domain simulation analysis using the EMTP-RV program.
