The invention discloses an intelligent transformer substation relay protection inspection system. The system comprises a server connected to an intelligent transformer substation station control layer network. The server is used for executing a method comprising the following steps of reading and analyzing a SCD file and acquiring an IP address list of a full station spacing layer device; starting an IEC61850MMS client and successively establishing MMS communication with the spacing layer device in the full station according to the IP address list; traversing and taking a fixed value of the device in the station, remote metering and a log and carrying out determination, wherein the step includes taking a protection fixed value information list and a soft pressure plate remote communication information list and comparing to the information list input by a user; and outputting an inspection result, wherein the step includes whether an output relay protection fixed value and pressure plate information are normal. In the invention, relay protection fixed value checking is realized; checking efficiency of a relay protection equipment fixed value is increased; a problem of low efficiency is solved and inspection quality is greatly increased.
