The invention relates to an integrated relay protection system of a distribution network station. The integrated relay protection system comprises the distribution network station with dual powers, and also comprises an integrated station protection device, wherein a first inlet wire current transformer, a second inlet wire current transformer, a sectionalized busbar current transformer, all first busbar outgoing wire current transformers and all second busbar outgoing wire current transformers are all connected with the input end of the integrated station protection device, and the output end of the integrated station protection device is connected with a first inlet wire switch, a second inlet wire switch, all first busbar outgoing wire switches and all second busbar outgoing wire switches. The integrated relay protection system of the distribution network station is compact in structure, can effectively save floor area, also can rapidly remove faults, prevents the expansion of accidents, improves protection sensitivity, and is safe and reliable.
