An artificial intelligence-based parameter setting value automatic calculation protection relays

摘要

The present invention relates to a protective relay device for automatically calculating correction values based on artificial intelligence. The device comprises: an input conversion unit which receives input information from a current transformer and a potential transformer and converts the information into data for a plurality of protective relays; an input unit which receives filters, encodes and temporarily stores the converted data for the plurality of protective relays; a data processing unit which analyzes a power system accident of a device by referring to the temporarily-stored data as fault accident case waveform data with respect to the device in which the power system accident occurred among the plurality of devices; a setting unit which includes a protective relay automatic calculation program, receives data on a collected protected device, performs automatic setting to a setting parameter value, and determines in real time whether or not the setting parameter value that is automatically set is appropriate during a power equipment operation; an output interface outputting a cutoff signal by configuring a protective element operation output with logic or receiving contact points from the outside; and a communication unit which transmits the automatically-set setting parameter value while communicating with the plurality of protective relays.
