摘要

The paper presents a new active diode bridge fault current limiter (FCL) topology, and compares it to the classic diode bridge, Series Dynamic Breaking Resistor (SDBR), and active diode bridge FCL circuits. The comparison is done using a benchmark system that includes a 9 MW wind turbine with a doubly fed induction generator (DFIG), two 50 MW synchronous generators, and three step-up transformers. The results show that all three FCLs improve transient stability by limiting the currents peak, terminal voltage drop, active and reactive powers, and torque transients.
