The research and design of feeder protection device of traction substation

摘要

In feeder line protection system, Considering the powerful Ethernet communication of the embedded ARM processor and the efficient and high-speed digital signal processing of the DSP processor, The multi-CPU structure with ARM and DSP is adopted. Dual-port RAM is used for data exchange between ARM and DSP. Then the system will be more applicable in electrified railway traction substation.
