SA weather: No link between blackout and renewable energy, experts say

Right - so these experts gave us the blackout by their PC renewable energy demands - but it's not their fault - just ask them!!!
 
The people of SA have been conned and badly let down by their government over many years - but if you keep electing them I guess you shouldn't expect any change for the better.
 
Never mind, the rest of the country will coninuer to subsidise them.

Can't see the connection? This comment in the article says it all.

 

"If you've got a wind farm or a coal-fired power station at the end of a transmission line, and that system either is taken out by a storm or is forced to shut down to protect itself from a storm, it doesn't matter what the energy source is."

 

Are we suggesting that nuclear or coal power is more reliable during extreme weather?

 

"The federal minister conceded South Australia’s use of renewable energy was not at fault in the blackout" > http://www.news.com.au/technology/enviro...78a3b3625a

 

 

P.S. Nice shot!

It's not something I'll ever understand.

 

Was made aware on another forum about facebook trolls targeting Sam Frost for years for no reason.

 

Saddened me to find out from an insider that a lot of the trolls were previously respected radio personalities (like Sam)

Don't be so obtuse!

 

The experts gave a system to SA that is not secure!!

 

That is a fact given the recent damage.

 

Hello?

 

Not everyone swallows the apologetics that the experts give - what else would they say?

 

A whole state loses power?

 

Not even a cyclone blacks out all of the NT, Qld or WA.

Better spell that out to Josh Frydenberg then... 'coz he's the one disagreeing with you

 

Feel free to umm... "blow us all over" with how you plan to get power from a grid via broken transmission lines

[Aloysius]

And exactly who provided single transmission lines?

 

Experts per chance? :blink:

[POWERZONE]

What single transmission lines? There are TWO lines. The Murray Link and the Heywood Interconnector.


Experts? Well given the hazardous nature, complex training and qualifications required to install and maintain HV lines I'd say the transmission lines were provided by "experts".


It's not quite the same as erecting a clothesline :LMAO:

When you have a little time try researching transmission line security and redundant systems - it will become clear .

 

As for erection of towers: I don't question the construction ability of the erectors - what is at question is the design of the transmission lines overall.

 

You know, the bigpicture, the plan, not the execution of the plan.

[POWERZONE]

Redundancy is used for isolated faults and system protection, not widespread destruction of transmission lines.

Have a read up about "Cascading failure" for more info

This is what really happened...

Storms[edit]

On the day of the failure, South Australia experienced a violent storm reported as being a once-in-50-year event.[2] There was gale force and storm force wind across wide areas of the state. It included at least two tornadoes in the vicinity of Blyth.[3] The state was hit by at least 80,000 lightning strikes.[4] The wind damaged a total of 23 pylons on electricity transmission lines, including damage on three of the four interconnectors connecting the Adelaide area to the north and west of the state.

Power grid[edit]

The South Australian power grid is operated by ElectraNet and connected to the National Electricity Market via two interconnectors to Victoria. These are the Heywood interconnector (recently upgraded to 650MW at 275kV)[5] in the southeast of the state and the Murraylink (220MW at 150kV) HVDC further north, connecting Berri to Red Cliffs in Victoria.[6] The Heywood interconnector had been down for upgrade earlier in the year, and was initially blamed for the widespread outage.

Blackout[edit]

The weather had resulted in localised power outages throughout the day, but at around 3:50 p.m. local time, almost the entire state power grid cut out. Early indications were that as the transmission lines in the Mid North failed due to damaged pylons, the automatic safety features in the network isolated the generators to protect both the generation facilities and the end consumers' equipment. Over a short period, this resulted in most of the state's distribution network being powered down as the transmission network acted to protect it.

Restoration[edit]

As so much of the network had been shut down, the authorities needed to act carefully to bring it back online and provide a stable network. This was initiated in the first few hours following the start of the outage, initially using the Victorian interconnectors to establish a stable frequency on the network, and gradually add South Australia's power generators to the network and restore power to areas as soon as possible. The initial focus was to restore power to the Adelaide metropolitan area, and suburbs started to regain power within about three hours, and much of the city power was restored by 10 p.m. By the following morning, power had been restored to most of the areas of Adelaide and the areas south and east of it that did not have storm damage to the distribution network. The substantial damage to the transmission network north of Adelaide meant that large areas of the Mid North and Eyre Peninsula did not have power restored within 24 hours, and further damaging weather indicated that it could be at least the end of the weekend before some of those areas were restored.[7]

Due to the extensive nature of the damage temporary transmission towers were sent by Western Power these towers can reach a height of 58 metres and take only one day to erect, it is expected that the towers will remain in use for 6 to 12 months while the permanent repairs are made.[8]

None of this happened as a result of the use of renewable energy. There is no connection and to allege as such is simply a political witch hunt.

You are talking about generation of energy - I'm talking about transmission of energy.

Redundancy in transmission means alternatives.

Lack of alternatives = state wide blackouts.

"Experts" determine the type, quality and number of transmission components.

Their results demonstrated recently are clearly less than acceptable.

Apparently the generation aspect did not fail - transmission failed.

Exactly what I've been saying Aloy > http://www.melbournechat.org/index.php?showtopic=6941&p=44900 :)

"If you've got a wind farm or a coal-fired power station at the end of a transmission line, and that system either is taken out by a storm or is forced to shut down to protect itself from a storm, it doesn't matter what the energy source is."


You are agreeing with the eye catching headline: "No link between blackout and renewable energy"


Electricity bills have a future!

Those poor folks in Brisbane, they sure do cop a heap of storms.

We had no power interruptions - but then we probably have better transmission tower design

Everyday Sexism report: Are girls and young women treated equally in Australia? Most say no
http://www.abc.net.au/news/2016-10-11/ar...ia/7918700

 

Without getting into the argument in the least that's not the point.

 

The question I have is this:

 

The headline talks about a "Sexism report"

 

The body of the article talks only about an opinion poll.

 

So is it a report or the results of a poll?
