Trevallyn Power Station
Oct. 8th, 2008 02:04 pmOne hydro-power station.
Trevallyn Power Station was built 1955, and replaced Duck Reach. There's background information (and maps) on the Hydro's web site. It's managed by Hydro Tasmania A few years back, the state-owned HEC was broken up into 3 companies: the Hydro, who generate the power; Transend, who transmit it, and Aurora, who deal with the consumer side.

Trevallyn Lake & is on the South Esk river, just up from the gorge. I have some idea of going up to the dam one day to take photos, but the bus doesn't run particularly close.
The water comes down a combination of tunnel & pipe to the power station, where it's divided into four streams.
At which point, we reach the limit of my knowledge on hydro power generation :) This picture on the Hydro site helps though.

First, the 1950s style control room. Mostly replaced now by a couple of PCs.
The next stop is right down on the turbine floor

There are four of these, but only #4 and #3 were operating.

This is the part up against the wall. The intake valve?

And the middle part.

This is turbine #1

The black column on #3 is turning, which is why it's shiny.

And the same with #4

There is one of these on the near side of each turbine thingy. I don't know what they do though.

Next, the alternator floor.

Exciting, isn't it?

(Insert your own bad joke here.) The guide, and I forget his name, says these are just here for display now. They've been replaced by electric (electronic?) tools.

It's not how many volts you have, it's what you do with them. The guide tells us people die every year from putting their tongue on a 9V battery.

Rotors?
Up to the top floor, which I think are the generators.


Am I the only one that thinks they look like alien spacecraft? The two at this end are the olders ones (above turbines #1 and #2).

"Units #1 and #2 reporting. The humans still seem oblivious to our true purpose."

Which appears to stealing all the water!

Inside an alien.

Important orange things.

Inside one of the cupboard things.
