Abstract:
A new kind of bridge type fault current limiter(FCL)which is used in power system has been presented. Detailed analysis has also been made including circuit’s principle,structure and working mode. The relationship of current in the branch of FCL and three types of working mode,that is,conduction without resistance,open circuit,and conduction with resistance,when the FCL in working condition are provided. In the mode of conduction with resistance,shunting effect has been considered which can reduce the fault current flow through the limiting inductance. Considering when IGBT switching works with different duty ratio,the output voltage,current and their harmonic component will also be changed. At end of this paper,part of the simulation and calculate result is given.
