One of these days the smart meter hoopla will die down and utilities will start layering distribution automation on top of their metering infrastructure. When they do they’ll discover that S&C Electric’s pioneering approach to distributed intelligence makes a great complement to centralized C&C. At least that’s Jesse Berst’s take on it. Click inside and see if you agree. |

After three years investigating distribution automation, National Grid embarked on a pilot in mid-2007. In January 2009, the first DA was activated. As this presentation details, the pilot used 900 Mhz spread spectrum radio for peer-to-peer communications between line devices and for its back haul to the nearest substation with existing SCADA communications. |

Buckeye Power, Inc. is the wholesale power supplier for the 25 electric distribution cooperatives operating in Ohio. The 25 cooperatives combined serve more than 380,000 homes and businesses in 77 of Ohio's 88 counties. To enhance system reliability, Buckeye Power wanted a system that could report outages from the more than 330 delivery points on their system. In addition, operations wanted power quality information from the delivery points as well. By combining outage data with power quality information, Buckeye could achieve better real-time monitoring of the delivery points on their system. |

As strategic elements that contribute to the vision of the Smart Grid drive requirements for increased visibility into the status of the power delivery infrastructure and operational awareness for the optimization of the delivery and use of energy, utilities are beginning to contrast the cost of a standalone distribution automation (DA) infrastructure with that of an AMI solution coupled with a DA deployment that leverages the synergies of a common communication platform. This white paper details how the ANSI C12.22 protocol is integral to creating that common communication platform. |
