Abstract Considering the influence of new energy Distributed Generators (DG) interconnection on the intelligent power distribution network,an extendable universal model of the distribution network with DG is constructed.Based on the equivalent conversion of model structure,the influence factors of direction finding misjudgment by power quality monitor is analyzed.Two influence law of direction finding for power quality (PQ) disturbance are proposed innovatively with DG interconnection,for the type of voltage sag or voltage temporary rise.Then,a new direction finding algorithm of PQ disturbance is presented,based on correction by influence law.Multiple Distributed Generators are connected to the IEEE 13 and the IEEE 34 model.The Matlab simulation shows that,the proposed new algorithm can enhance the accuracy of direction finding for PQ disturbance,and this concise algorithm has the advantages of strong ability to resist noise.

Key words： Distributed generation power quality disturbance source direction finding distribution network
