The unified power flow controller with fault current limiting（UPFC-FCL）can effectively protect series converter from being damaged by short circuit current.In view of the inadequacy of existing power control strategies for UPFC-FCL，a power system model with UPFC-FCL is developed，and a power control strategy based on line current control is proposed.The start-stop process of UPFC-FCL is analyzed，then a complete start-stop control scheme is proposed.In the start process，the charging rate of DC capacitor is limited by current-limiting resistance，which prevents overvoltage or overcurrent of the equipment.In the stop process，the design requirements of discharge resistance can be reduced as the energy of DC capacitance is partly released through the shunt converter.PSCAD/EMTDC simulation results demonstrate that the UPFC-FCL power control strategy based on line current control has good dynamic and steady performance，and the start-stop control scheme is rational and effective.
