| Abstract: | According to the type of the DG,the working situations of the reclosing are studied.The actual parameters of DG's rated capacity and transient reactance are adopted.According to the location and capacity of the DG, the possibility of auto-reclosing is analyzed,and the parallel feed inverter used in this system and its control method is presented.The system model and calculation results are given in MATLAB.It shows that the auto-reclosing technique is feasible in the distributed generation system and for some DGs connected to the net by inverters,the current instantaneous feedback control can realize the switching condition. |
