Redundancy design method for intelligent primary equipment IED devices

The invention discloses a redundancy design method for intelligent primary equipment IED devices, which belongs to the technical field of power. A backstage system in a substation, a first LED device,a second LED device, a signal merging device and the primary equipment are built, simultaneous running and mutual standby of two sets of devices are realized, and the technical problem of redundancycontrol of the primary equipment body control cabinet is solved. Through simultaneous running of two sets of mutual-redundancy LED devices, information sharing and mutual standby, contents such as therelated data of the intelligent primary equipment, the running state and the control information are shared with the two sets of LED devices, information of the two sets of LED devices is ensured tobe consistent, the two sets of equipment can simultaneously perform data interaction with two sets of backstage systems, the running reliability of the equipment is improved, the fault rate is greatlyreduced, the economic loss i
