【 摘 要 】

This article has completely analyzed and introduced the intelligent substation secondary system. Firstly, the structure of the "three-tier and two-network" of the secondary system of the smart substation is introduced, and the concepts of "three-tier" and "two-network" are described in detail. Secondly, according to the three classifications of "station control layer", "space layer" and "process layer", the configuration and related requirements of the secondary equipment of the smart substation under different voltage levels are introduced in detail. Finally, the network structure of the secondary system of the smart substation is introduced, and the IEC 61850 system and the smart substation network structure are described in detail.
