Realization of the teleprotection equipment interface for working with PLC equipment using FPGA logic

This paper describes the realization of the interface in the teleprotection equipment for work with PLC equipment, and so to transmit teleprotection commands over power lines. The properties of the teleprotection equipment are shortly described, and after the realization of the line unit using FPGA technology (XILINX XC3S700AN) is described in details. Fourth part describes the simulation model realized in MATLAB-Simulink program.
