Innovation in Substation Ethernet Networks How to Achieve Flexibility by Combining New Protocols and New Hardware Concepts
Advantages of Digital Substation & Smart Grid Improved measuring accuracy & performance Increased safety & lower environmental impact Improved cost of ownership by elimination of copper wires Smart Grid Improved reliability & efficiency Enabling of renewables & cleantech apps Increased consumer engagement
The Drivers – Digital Substation and Smart Distribution Grid Communication Requirements & Goals Fully digital high voltage substations and smart distribution grid require robust, reliable, secure and flexible communications infrastructure. Smart Grid implies replacement of analogue signals, large amount of copper wires and legacy systems by transition to digital data transmission over standard Ethernet and IP communications. The long term goal is to reduce costs while increasing efficiency by migrating all operational services and mission-critical applications to use a unified all-IP communications network.
The Challenge - Need for Flexibility in Substation Ethernet Networks Move the Utility communications network to make digital substations and smart distribution grid real, without: Making current operating capital investments obsolete A massive investment in new technology, procedures and training Expanding physical facilities.
The Challenge - Evolution Path From the Legacy Environment to the Future The Solution Introduce new technology that provides utilities with a simple, cost-effective evolutionary path. This technology should allow customers to handle higher data rates, adopt new standards and meet new regulatory requirements; Gracefully, in a deliberate, controlled manner Without massive “forklift upgrades” Without battles for rate increases Solution must be flexible, future-proof, robust, with a low-cost of ownership, high-density and handle gigabit speed.
