The invention provides a multi-stage current protection performance test method and system for optimizing a test scene. A test management host generates a topological graph model of a power distribution network to be tested; setting a fault test scene based on different test fault types and other fault scene factors in the topological graph model of the power distribution network to be tested, and forming a fault scene original sample set; optimizing and establishing a typical fault scene sample set by adopting an orthogonal test method; the test management host creates a fault scene database based on the typical fault scene sample set; constructing a protection performance test system by using an RT-LAB platform and combining with a protection device to be tested; and the protection performance testing system completes performance testing of the to-be-tested protection device in sequence based on the fault scene database. According to the method, the problem of power failure of the to-be-tested power distrib
