Altera Corp. offers an FPGA-based High-availability Seamless Redundancy (HSR) and Parallel Redundancy Protocol (PRP) reference design that simplifies development and implementation of highly reliable mission-critical communications systems in smart grid substations.

Developed jointly with Flexibilis Oy, the IEC 62439-3-compliant reference design includes Flexibilis Redundant Switch (FRS) IP implemented on an Altera low-power, low-cost Cyclone-class FPGA or Cyclone V SoC.

"A key trend today in developing a smarter power grid is bidirectional communication and real-time control of the equipment in the grid's transmission and distribution substations," said Jason Chiang, senior strategic marketing manager in Altera's Industrial Business Unit. "Our FPGA-based HSR/PRP reference design enables equipment manufactures to build flexibility, performance, reliability and product longevity into their systems while lowering system costs and future proofing designs."

The Flexibilis HSR/PRP IP included in the reference design is a triple-speed 10/100/1000Mbit/s Ethernet Layer 2 switch that is scalable from 3 to 8 ports and is compliant with the IEC 62439-3 standard. The IP is optimised for use on an Altera low-power, low-cost Cyclone IV FPGA, Cyclone V FPGA or Cyclone V SoC, which feature an integrated dual-core ARM Cortex-A9 processor sub-system. Cyclone V SoCs enable customers to reduce component costs by implementing their HSR/PRP switch along with the associated software stacks running on the ARM processor sub-system in the FPGA. For timing synchronisation, the HSR/PRP solution supports IEEE 1588 Precision Time Protocol (PTP) Version 2.

Altera and Flexibilis make it easy to implement an FPGA-based HSR/PRP Ethernet switch. Combining Altera FPGAs with the FRS IP provides an easy and cost-effective way to implement highly reliable mission-critical communications systems in smart grid substations by offering no license negotiation, no up-front licensing costs and no per-unit royalty reporting.
