With the development of new technologies, materials, process of secondary system in substation, test technologies of secondary system are continuous upgraded. In order to guarantee the security and stability operation of digital substation, field test content of secondary system of substation and key technologies of secondary system and its test methods under different network modes of process layer are studied combing with the overall technology development history of substation secondary system and the analysis of new technology and new characteristics of digital substation secondary system. Study achievements were applied in the field acceptance project of 220 kV Feicui digital substation in Wuzhou power grid, and achieved predicted effect. Finally, the system level test platform is discussed, which provides reference for the development of test platform of secondary system of digital substation with more perfect test functions and higher test efficiency.
