The data in the shared memory is a structure, including a data update flag, a fault status flag, and a fault sequence number. The new recording file is a copy of the template file and is renamed.

9. The multi-IED simulation method based on SCD file according to any one of claims 1 to 8, characterized in that: The interface of the IED simulation component is hidden by default when it is started. The device simulation console controls the display and hiding of the IED simulation component interface through shared memory. The data of the shared memory is a structure, including a data update flag and a window display flag.

10. The multi-IED simulation system based on SCD file is characterized by: include: The IED parameter acquisition module loads the SCD file through the device simulation console, demultiplexes the SCD file into multiple CID files, obtains the IED parameters therein and displays them in a list on its main interface; IED startup module, through the device simulation console, selects to start all or part of the IEDs according to the IED parameters. Each IED corresponds to an IED simulation component with remote signaling function, remote measurement function, setting function, parameter function and electricity function; IED simulation module, the IED simulation component parses the startup parameters generated by the simulation console and then starts the IED simulation process; In the simulation result generation module, the device simulation console interacts with the IED simulation component through shared memory to complete the automatic change of telesignal status, automatic change of telemetered value and automatic generation of recorded waveform.
