主　　题：Fault current limiting multi-terminal high volt-age direct current(MTDC)grid power balance DC power flow controller 

摘      要：In order to overcome the problems of power flow control and fault current limiting in multi-terminal high voltage direct current(MTDC)grids,this paper proposes a modular multi-terminal DC power flow controller(MM-DCPFC)with fault current limiting *** topology structure,operation principle,and equivalent circuit of MM-DCPFC are introduced,and such a structure has the advantages of modularity and *** power balance mechanism is studied and a hierarchical power balance control strategy is *** results show that MM-DCPFC can achieve internal power exchange,which avoids the use of external power *** fault characteristics of MM-DCPFC are analyzed,fault current limiting and self-protection methods are proposed,and the factors affecting the current limiting capability are *** simulation models are established in PLECS,and the simulation results verify the effectiveness of MM-DCPFC in power flow control,fault current limiting,and *** addition,a prototype is developed to validate the function and control method of MM-DCPFC.
