Research On Simulation Platform Of Electrical Cyber-physical System Based On IEC61850

Based on the IEC 61850 power system automation standard,also based on primary and secondary equipment models and raw data of a 220 k V smart substation,this paper uses PSCAD/EMTDC to establish various intelligent electronic devices in the process layer,bay layer,and station control layer of the smart substation in order.Based on this model,according to this model,OPNET uses the process layer,node layer,and network layer to establish the communication system model corresponding to the physical system layer by layer,and specifies the data and information processing methods and communication protocols.This paper proposes a simultaneous synchronization method for physical information fusion systems.It uses the high-level architecture of OPNET in the external interfaces of HLA-PM and PSCAD to establish synchronous simulation interaction classes and the two systems correspond one by one,setting up a specific synchronization process.Synchronize the software of two different simulation timings in sequence so that the data and information generated by PSCAD can be transmitted to the process layer of the corresponding module of OPNET through a specific package.The resulting control information is returned from OPNET to PSCAD via RTI again.And execute the corresponding command.The physical information system of a 220 k V substation is simulated.The results show that the established CPS model can meet the requirements of the IEC 61850 communication system and the protection control of the physical system.This simulation platform can be used as a simultaneous simulation tool for the power CPS system.And on the basis of modifying the corresponding model,it can meet the simulation needs of other models.
