Intelligent substation protection debugging method

The invention provides an intelligent substation protection debugging method, which comprises the following steps of: S1, constructing an integrated digital relay protection test system, and accessing an optical fiber of a device to be debugged into a test interface of the integrated digital relay protection test system; s2, importing the SCD file of the intelligent substation where the device to be debugged is located into a control module of the integrated digital relay protection test system, and analyzing the SCD file; s3, configuring data interaction between the optical ports according to the SCD file; s4, simulating fault parameters when the device to be debugged fails, and outputting the fault parameters to the device to be debugged by the integrated digital relay protection test system for debugging test; s5, the integrated digital relay protection test system records the result of the device to be debugged in the debugging test; and S6, repeating the steps S1 to S5 until all the to-be-debugged device
