概要	This paper describes a new fault diagnosis method for distribution networks load node with photovoltaics (PV) generator embedded based on an equivalent-input-disturbance (EID) approach. For this method, the faults occurred to node are regarded as disturbances of system, which can be obtained by EID approach. Through analysis of the EID, we can diagnose the fault occurs or not, even identify the type of faults further. Firstly, a dynamic model of load node equivalent circuit for fault diagnosis is built. Next, an EID estimation for the model is designed. Lastly, by analysis of simulation results, the effectiveness of the method is demonstrated.
