Research and Design of Portable Fault Recorder Based on FPGA

Facing the lack of traditional fault recorder technology and according to data collection requirements of the fault analysis of power system, this article established a new type of portable recorder that was designed surrounding FPGA. The fault recorder abandoned the “multi-layer structure” and used single FPGA chip and embedded CPU core to complete the master function. This designed fault recorder can run independently from the computer and had the features of small size, light weight, higher degree of integration and so on.
