The fixed series capacitor is inserted into a transmission line to increase the maximum transmittable power. Nevertheless, one of the reasons impeding the use of series capacitive compensation widely with wind farms is the potential threat of sub-synchronous resonance (SSR), especially at high compensation levels. This phenomenon has an adverse impact on system stability.
