SCADA stands for Supervisor Control And Data Acquisition. It is a production automation and control system based on PCs.
It is widely used in many fields :
e.g. power generation, water system, oil industy, chemistry, automobile industry.
Different fields need different functions, but they all have bellow features :

Graphical interface

Process simulation

Real time and historic trend logging

Alam system

Data acquisition and recording

CAMBRIDGE, Mass.–U.S. energy objectives are closely intertwined with–and in many cases, rely upon–the country’s broadband infrastructure, government officials and smart-grid company executives say.
The Federal Communications Commission on Monday held a “field hearing” at the Massachusetts Institute of Technology on the role of communications in energy and environment. It was an information-gathering session designed to help set a national broadband strategy.

Nowadays we have several issues to face that are causing concern to humanity in general and the western world specifically. I don’t think I need to repeat them here but basically they are environmental as well as geopolitical in nature. Hence, the old coal or oil burning power plant needs to be phased out and we must become much more efficient at generating and delivering electricity to end users or the costs become extraordinary over time.
Everywhere I look these days I see Smart Grid this and Smart Grid that and Smart Grid everything else. Hmmm … must be… Continue reading

In countries such as the U.S., the ‘Smart Grid’ is seen as the newest solution to stop global warming, which optimizes the delivery of electricity through IT. Function-rich electric meters are needed at individual homes for the smart grid to be implemented. HD-PLC has drawn attention as one of the solutions to make the meters more function-rich.
The smart grid is a next generation electricity network that automatically adjusts the flow of electricity between suppliers and consumers by using IT. It aims to become an electricity network where homes, businesses and power utility companies cooperate together in using electricity… Continue reading

Julian Murdoch From Hard Assets Investor Writes: President Obama made the overhaul of the nation’s electrical infrastructure a vocal part of his 2008 campaign. In an interview with MSNBC’s Rachel Maddow just days before the election, he outlined his promise of involvement:
“One of, I think, the most important infrastructure projects that we need is a whole new electricity grid. Because if we’re going to be serious about renewable energy, I want to be able to get wind power from North Dakota to population centers, like Chicago. And we’re going to have to have a smart grid. If we… Continue reading

As the movement to make electrical grids “smarter” grows around the globe, defining just what a smart grid is — for both consumers and power producers — takes on critical importance. Today, GE is hosting a symposium at its Global Research Center in Niskayuna, New York to spotlight smart technologies that are being fielded now — and how the grid will look in the near future with the next generation of GE innovations. As part of the symposium, GE unveiled what it’s calling the “Net Zero Energy Home” concept — as well as new consumer polling data and smart grid… Continue reading

Zensys’s Z-Wave has been trying to get adopted as a smart grid technology, but it’s been slow going. Maybe Sigma Designs can help.

Sigma Designs has bought Zensys for an undisclosed amount. Zensys has been trying to gain traction in the smart grid market but hasn’t experienced a tremendous amount of success.
Zensys is the primary driver behind Z-Wave, a wireless, energy-efficient protocol that allows lights, appliances, security cameras, thermostats and other devices to talk to each other. Z-Wave is a single chip solution and is cheaper than competing technologies like ZigBee and WiFi, say advocates.
Although Z-Wave… Continue reading

In a much-discussed op-ed column in Monday’s New York Times, Nobel laureate and former Vice President Al Gore declared his support for a crash program to modernize the nation’s electrical system:
We should begin the planning and construction of a unified national smart grid for the transport of renewable electricity from the rural places where it is mostly generated to the cities where it is mostly used. New high-voltage, low-loss underground lines can be designed with “smart” features that provide consumers with sophisticated information and easy-to-use tools for conserving electricity, eliminating inefficiency and reducing their energy bills. The cost of this… Continue reading
