Abstract :
A new fault current limiter with thyristor-controlled impedance (FCL-TCI) is proposed. The FCL-TCI helps in improving the steady-state stability limit, while providing an effective reduction of short circuit current during the fault. Analytical, experimental and computer simulation studies on a working model are conducted. The effects on improvement of stability limits and reduction of the short-circuit current are shown using the experimental model. The economical benefits of the FCL-TCI are due to the extension of the useful life of the existing circuit breakers and power transformers, and to the improvement in the performance of the transmission line.<>
