This article analyses the impact of DG on the distribution grid arc.As arc resistance is a non-linear function of the fault current,it further presents a new iterative algorithm and uses this algorithm and IEEE34 power distribution network to calculate fault current and arc resistance of the distribution system with DG.It analyses the factors affecting the fault characteristics of the distribution network with DG,and gives suggestions on how to raise the safety of the distribution network.
