In this paper a novel discrete control strategy to mitigate subsynchronous resonance (SSR) oscillations is proposed for thyristor controlled series compensators (TCSC) having a discrete type of control over compensation level, since it behaves like a conventional series compensation under normal conditions. The control strategy is based on the phase unbalance concept and is simple and easy to implement in hardware.
