Cisco unveiled the GridBlocks Architecture, a blueprint for
integrating digital communications and the electric grid, including
support for legacy utility communications networks. Cisco also rolled
out field area network (FAN) equipment and transmission and substation
switches and routers. The company is offering services to help utilities
plan, design and optimize their new grid infrastructures.
Cisco’s GridBlocks Architecture is designed to give utility operators
a holistic view of their grid communications infrastructure while also
enabling them to focus on particular elements of the network that may
have unique requirements. It’s intended to be adaptable to these
requirements, such as support for legacy infrastructure or regional
compliance regulations.
The FAN combines smart grid metering, distribution, data collection
and utility software from Itron with Cisco’s IPv6-based routers and
switches. Cisco and Itron announced an alliance around IPv6-based smart grid infrastructure back in 2010.
The FAN includes a new ruggedized IPv6 router line from Cisco: the
1000 series Connected Grid Router. The router comes in models for
outdoor pole-top mount – the CGR 1240 -- and indoor DIN-rail mount with
the CGR 1120. Each supports 2G/3G, WiMAX and RF wireless mesh
connectivity.
The FAN also includes new endpoints, device management and network
management systems such as the Cisco Connected Grid Network Management
System, which is designed to provide end-to-end monitoring and control
for up to 10 million endpoints.
For transmission and substations, Cisco unveiled modules for its 2000
Series Connected Grid Routers that support wireless 4G/LTE, ISDN WAN
and DSL networks. Cisco also enhanced security on the 2000 series with
intrusion prevention / intrusion detection, and support for SCADA
signatures. In addition, the Cisco 2000 supports source-specific
multicast for transfer and sharing of data across utility boundaries.
For implementation, Cisco developed the Connected Grid Visualization
and Design tool to allow engineers to visualize in a single interface
the energy delivery network CIM diagrams, the IEC 61850 protection
schema for intelligent electronic devices, and the communications
network. This helps engineers to design, model, and simulate all three
networks, and standardize designs across hundreds or thousands of
substations.
