| Abstract: | Short circuit is a serious fault in power network. Some novel circuit topologies of current limiter using power electronic technology have been developed, which can limit the fault current to any desired level without much penalty. The operating principle and control strategies of such current limiters are discussed in detail. Simulation and experimental results are given to verify the performance of the current limiter, which can meet the requirements set for locations of bus tie, feeder, as well as the main transformer in the distribution network. |
