Zusammenfassung:A method of pre-warning and identifying a fault of relay protection of an intelligent substation is provided, which is specifically carried out according to following steps. Step 1: performing fault diagnosis on hardware input signals of relay protection equipment; step 2: performing software fault diagnosis on a relay protection device; step 3: developing a MATLAB-based anti-false pre-warning platform for the relay protection of the intelligent substation by combining step 1 and step 2; and step 4: based on the MATLAB-based anti-false pre-warning platform for the relay protection of the intelligent substation, according to fault recording sampling information of the substation, accurately identifying a fault area, pre-judging a possible action situation of protection, and giving pre-warning information.
