Altera Corp. has expanded its field-programmable gate array (FPGA)-based solutions targeting smart energy systems by announcing a High-availability Seamless Redundancy (HSR) and Parallel Redundancy Protocol (PRP) reference design targeting smart grid substation automation equipment.

Developed jointly with Flexibilis Oy, a provider of networking equipment and technologies for wireless and wired applications, the IEC 62439-3-compliant reference design includes Flexibilis Redundant Switch intellectual property implemented on an Altera low-power Cyclone-class FPGA or Cyclone V system-on-chip. According to Altera, the reference design simplifies development and implementation of mission-critical communications systems in smart grid substations.

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