Ensuring future reliability of the North-American power grid

Leveraging Smarter Distribution Grids

Building intelligent energy grids wont cost nearly as much if we leverage our networks. Look at what happening now in Australia, this is a good model to follow..

For over a hundred years power providers have essentially relied on their customers to notify them of power outages. Without any automated-detection system in place, power companies don’t know the power is out until a customer notifies them. This will change with the deployment new wireless sensors from a company based in Australia.

Telepathx Ltd, a wireless sensor developer based in Victoria, Australia, recently announced that the release of their new product will make this inherent dependency on energy customers a notion of the past. Telepathx Ltd is among the leading industry developers of advanced metering infrastructure (AMI) in Australia.

The long-awaited release of Telepathx’ Pinpoint intelligent cutout sensor uses the company’s enhancements to radio frequency identification (RFID) technology to provide utility companies with the instant communications they need to pinpoint electrical outages. With Pinpoint sensors in place on a smart power grid, should a failure occur the power utility is notified within seconds of the precise location of the power failure including the specific device and cabling that have failed.

Power failure reporting at this level of precision has never before been attainable, but now with AMI technology taking shape throughout Australia, these sensors can be used that will minimize power outages to an absolute minimum.

According to April Sommers, an energy analyst, “Statistically 84% of all power outages or blackouts in urban and outer urban settings are caused by falling tree limbs or animals that come in contact with the overhead power lines, this intelligent cutout fuse technology can’t stop that from happening, but what it will do is provide an instantaneous notification to energy providers reducing the report and response times of faults from hours to mere seconds, something entire communities will benefit from.”

Previously, a power company could remain unaware of a power outage for minutes or even ours until telephoned customer complaints give a general idea where the issue is happening. Pinpoint sensors will greatly enhance a utility’s ability to respond to problems and enhance their ability to efficiently dispatch work crews to fix the problem.

Smart power grids will effectively manage themselves and notify the proper authorities when necessary. Sommers adds, “reducing customer minutes off supply or CMOS is what these guys [Pinpoint sensors] do best, forget about managing apparatus with streams of data or waiting for calls to come in; this reactive technology teaches the network to manage itself and alert authorities when something’s amiss.”

Telepathx general manager Mike Walsh confirms that “In addition to bringing intelligence to energy networks the multi purpose machine to machine (M2M) wireless sensor networks being developed by the company would for starters monitor fire ignitions, auto collisions, floods, mudslides, asset tracking and consumer/industrial alarm systems, reading water, gas and electric meters or AMR/AMI services would follow.”

It’s very clear that the ongoing effort to develop smart meter technology has very far reaching effects in efficiency, monetary savings, and enhanced public safety. Smart meters will reduce carbon emissions to the atmosphere, but will have many other consequential benefits once the items become commonplace.

James Eades, CEO of Telepathx, adds, “This communications aggregation platform was designed and developed to consolidate the fragmented communications services that exist in our urban areas, and will benefit entire communities not just the energy sector; essential service providers such as police, emergency services, transportation networks operators, utilities even sewerage plants and M2M operators would benefit from leveraging services off the platform.”

Commenting on the Pinpoint sensors, Eades said “We have developed what many are calling the optimal model for building out the intelligent distribution grid; for the simple reason that our platform goes well beyond managing energy assets to generate revenues the day it’s installed not decades. Currently we are also exploring opportunities with several smart meter manufacturers on the issue of converging and leveraging of each others platform, a move that will make meters more intelligent than ever imagined.”

Pinpoint sensors integrated into smart meters and home appliances have the potential to create home area networks (HANs) capable of remote control of appliances in the home by either the individual consumer or the power company. RFID technology operates over radio frequencies, eliminating the need to install computer equipment that other wireless technologies require.
