The invention provides an intelligent substation intelligent terminal analog device and a using method thereof. The analog device comprises a human-computer interaction module, a data processing module, a sending and storing RAM, an MII sending module, a receiving and storing RAM, an MII receiving storage module and a multi-path light Ethernet physical circuit module. The using method comprises the following steps of (1) extracting position virtual terminals and information of switching equipment, (2) setting numbers and position initial values of the switching equipment, (3) displaying a wiring diagram in a graphic mode or displaying the switching equipment in a list, (4) setting mapping of a circuit breaker tripping virtual terminal, a circuit breaker switching signal virtual terminal, a switching equipment remote control signal virtual terminal and a switching equipment operation locking signal virtual terminal, (5) sending a GOOSSE report and (6) turning off the substation intelligent terminal analog device. The device is simple in debugging and high in efficiency, a large number of intelligent terminals are not needed, investment is saved, the service life of the switching equipment is prolonged, and the workload and labor intensity for turning on and off on-site switching equipment are greatly lowered.
