A Novel Design of Traveling Wave Protection Device in EHV Transmission Lines Based-On ARM and FPGA

Abstract:

As it is difficult to realize the traveling wave protection principle based on wavelet analysis in microcomputer protection device, a new microcomputer protection architecture based on FPGA+ARM is put forward in this paper This architecture make full use of ARM to complete relay protection principle, communication and the realization of the man-machine interface for the powerful transaction processing ability, and make use of FPGA to complete complex real-time wavelet analysis by a logic circuit for the characteristics of FPGA in high speed real-time parallel computation. It proves in experiment that this scheme is a good solution for the realization of travelling wave protection.
