Summary description
Main benefits
The customer is an electricity distribution system operator that deploys a new smart-grid
network, including smart-meters and distributed grid automation.
Emerging electricity smart grid solutions optimize the electricity network by adding
distributed mini-generators, enhancing the distributed automation of the grid and
dynamically adjusting the power consumption of the consumers. The resulting smart grid
introduces additional elements into the distributed medium/low voltage transformation
sites such as smart meter concentrators, grid automation monitoring and control devices.
As a result, they evolve into intelligent secondary sub-stations with online communication
with the control center.
The RADiFlow 3080 industrial Ethernet switch available from RAD Data Communications is
deployed at every secondary sub-station to connect local devices to the aggregation
network via an external PLC and/or WiMAX modems with RSTP topology for redundancy. In
addition, the switch provides a for the IEC 104 protocol to secure
the distributed automation arriving to the controllers at each site.
Optimized networking solution for secondary sub-stations using the compact yet highly
integrated functions in the ruggedized switch include Ethernet switching and IP routing,
encrypted IPSec tunnels, a variety of interfaces, including Ethernet, copper and fiber, and
an integrated cellular modem.
Advanced security solution protecting distributed automation devices from malicious
access by attackers who already have gained access to the internal network. This is
achieved using the service-aware firewall integrated into the switch, which continuously
analyzes the grid automation communication protocols that reach every secondary sub-
station over Ethernet/MPLS.

Such intelligent functionality requires online communications, which presents several
challenges for the electricity distribution system operator
Fitness for harsh environmental conditions
Support for various wireline and wireless backbone connections
Securing sensitive information when using a public network
Securing the critical distributed automation application
Connecting legacy equipment to the IP-based network
The RADiflow 3080 is uniquely optimized to meet all of these requirements by providing:
A ruggedized system compliant to IEC 61850-3/IEEE 1613 requirements
Copper and fiber Ethernet ports and integrated 2G/3G cellular modem
GRE over IPSec tunnels for use over the public backbone
Application security using a distributed service-aware firewall for the specific industrial
automation protocols used in the smart-grid network (i.e. IEC 104)
Application convergence, using Ethernet and serial user ports, with an application gateway
for serial-based devices to the Ethernet network (i.e. IEC 101 to IEC 104 gateway)
