The distributed power generation power output in the micro-grid(MG)is uncertain.In case of fault occurring,the parameters are variable.In order to enable students to intuitively understand the evolution law of MG characteristic parameters under different fault conditions,this paper designs a simulation experiment of MG in the condition of multi-fault.Firstly,the control strategy of MG is selected.In the MG fault,on/off grid conditions are analyzed.Secondly,the simulation,experimental verification scheme and process of MG are designed under the condition of normal working,single-phase short circuit,three-phase short circuit and power failure.The evolution characteristics of experimental simulation data under different working conditions are analyzed in detail.Finally,students can better understand the characteristics changing of MG in the process of failure through the combination of virtual simulation and actual verification,and their hands-on practice ability is improved.
