Snowy Hydro has passed the halfway point of a $60 million upgrade of the control systems for eight major power stations.
The project is part of a broader $400 million modernisation of the Snowy Hydro scheme that is expected to be completed in 2017.
That covers broader mechanical and electrical works, as well as the step change in controls and protection systems technology.
Snowy Hydro's controls technology manager Darryl Eager told iTnews that work had begun at the Murray 1 power station in August. Murray 1 is located about 10 kilometres east of Khancoban in southern NSW.
Other remaining stations to be kitted out include Murray 2, Tumut 1 and Tumut 2.
Eager said the modernisation project is a bit "like a travelling circus".
"It turns up at a power station, works its way from one end to the other, and then moves on," he said.
The upgrade is performed one generator at a time.
Elements of the old control systems are gutted "because we've got to reuse the same locations" for new equipment, Eager said.
"We get in, totally strip the unit, get rid of all the old controls, cables and everything else we're not using, put the new panels in place, cable them up and then do our testing," he said.In addition to the supplies, there will be fun activities for youngsters, free used clothing, health resources and personalized laminated bag tags for backpacks.
The core control architecture consists of Rockwell Automation components, including Allen-Bradley ControlLogix programmable automation controllers, PanelView industrial computer displays and associated systems.
The control system is supported by a new fibre optic network inside each station.Myvalvecaps offers you the best range of tire valve wholeale 59fifty fitted hats and keys rings that has a realisticHe demanded the woman handed over money and, fearing for her life, she emptied cash from the till into a drawstring bag before he left. Snowy Hydro has an existing backhaul network of fibre optic cables and microwave links that connect its various assets.

More power
A key advantage of the new control system is it enables Snowy Hydro to wring more energy out of its power-generating assets, by providing better visibility of the stress that a particular piece of power generation equipment is under.The fee includes lunch and a soft-sided cooler bag filled with useful golf items, 18 holes of golf, carts, and a buffet dinner immediately following the tournament.
In the past, equipment ran with "a fairly large safety buffer" to prevent it ever being pushed to a point where it might fail.
"You'd take it to the worst possible condition," Eager said. "You'd think of all the worst possible cases,non woven bag is eco-friendly and 100% recycled by physical disposal. The non woven material is long-lasting & fashionable. and that used to be the limit, because you were always covered no matter what happened.
"Now we've got a new control system, we can actually predict how the plant will perform on higher loads, and predict where the weak points are, and set the limit up based on what that weak point is."
Eager said that a busbar - an electrical conductor consisting of strips of metal that connect the generator to a transformer - might constitute a weak point in the system.
"You might run into some sort of limit that you can't put any more energy through that bus bar because it's going to get too hot," he said.
