IEEE C37.94 multiplexer for Smart Grid IEC-61850 teleprotection system

Client

A European company specializing in manufacturing equipment for protecting power systems.


Challenge

To design IEEE C37.94 multiplexer. 


Solution

We developed a mechanical design, PCB, and FPGA design for the IEEE C37.94 interface converter. The device serves as a part of the Smart Grid IEC-61850 teleprotection system.

Features:

  • Xilinx Spartan FPGA
  • SGMII interface to host processor
  • 2 x optical Ethernet 100BaseFX4
  • 2 x optical ports IEEE C37.94

FPGA firmware blocks:

  • RMII MAC, HDLC, IEEE C37.94
  • Bit and frame synchronization recovery
  • MDIO and SGMII/GMII control
