Applications Overview

The Cisco 1120 Connected Grid Router is a ruggedized communication platform, designed for use inside substations or utility cabinets. This platform is built to meet the communication infrastructure needs of electric, gas, and water utilities.

The router provides an end-to-end communication network that enables increased power grid efficiency and reliability, reduced energy consumption, and reduced greenhouse gas emissions. The router also enables distributed intelligence for converged smart grid applications, including:

■Advanced Metering Infrastructure (AMI)

■Distribution Automation (DA)

■Integration of Distributed Energy Resources (DER)

■Remote workforce automation

The router provides reliable and secure real-time communication between network systems and the many devices that exist on the distribution grid, including meters, sensors, protection relays, Intelligent Electronic Devices (IEDs), plug-in electric vehicle (PEV) charging stations, and distributed solar farms. Network data is forwarded and processed over secure communication links between devices within the distribution grid for local decision processing.

Additionally, this data is sent to Supervisory Control and Data Acquisition (SCADA) systems and other management systems. The router supports physical connection to legacy distribution automation (DA) devices (over the serial port); the data from these devices can also be sent to central SCADA systems using protocol translation over the IP network.
