Abstract

This paper investigates the extent of the effectiveness of the phase-wise compensation scheme to mitigate subsynchronous resonance in a large network. The compensation scheme was proposed in 1990 to lessen the risk of subsynchronous resonance (SSR). This paper presents the studies performed on a 16 machines, 68 bus network to evaluate the effectiveness of the scheme on dynamic instability and transient torque amplification problem due to subsynchronous resonance. SSR analysis is performed using both frequency scanning technique and electromagnetic transient simulations.
