This work analyzes post-fault commutation failures and their effects in a thyristor based line commutated HVDC link. Simulation results of the example case available in PSCAD® reveal these failures. Two schemes have been suggested to mitigate these effects. Simulations of the suggested schemes show that these can swiftly and effectively control fault currents as well as post fault commutation failures.
