Abstract:
Aiming at the problem of micro-grid faults,this paper by analyzing the operating characteristics of the inverter controlled by PQ and VF develops an equivalent mathematical model based on the inverter control strategy,and gives the boundary condition of fault state. The work characteristics of the micro-grid island operation is considered by using the node voltage and node current before and after fault state,derived the equation of voltage and current at PCC(point of common coupling),and a more precise analysis method is established when the system is in three phase short circuit fault. At last,by using the PSCAD,a simulation system of isolated island operation of low voltage of 220 V is built,and the validity of the proposed method is tested.
