# 基于网络分区的大电网故障限流器的优化布点方法Optimal Distribution of Fault Current Limiter in Power Grids Based on Network Partition

Abstract: The short-circuit current can be quickly limited by the fault current limiter (FCL) to ensure the system safe and stable. A new method for fault current limiter distribution optimization is pre-sented. Large-scale power grids are first equivalently treated to each partition and through short-circuit calculation, the distribution coefficients of short-circuit current of each branch are got. According to the value of distribution coefficients of short-circuit current, the location of the FCL can be selected. Then the optimum positions are determined combined with the economy of FCL. Finally, the validity of the method is proved through the simulation of a real regional power grid, optimal distribution of FCL is achieved and the excessive short-circuit current is limited.
