NE Grid Collapses

[INDIC]

Now I understood why Chinese-Dragon is embarrassed with laman, kkacer.

Ontopic:- Electricity fully restored in North-East.

 

[Bhairava]

Hope the problem doesn't spread to south.

Dont worry our grid is separate and not connected to rest of India, afaik...

Guys I have a question - If India is suffering from electricity shortage then why India wants to export electricity to Pakistan?Doesn't make any sense.

Arey baba, this is not loadshedding - this is grid failure, reasons for which were given in earlier posts.

you know all you had to do was click on the link i provided and read it first instead of embarrassing your self and the clowns who thanked your for it here is what your minister had to say.

Looks like I can learn a few things from you on the art of clowning.You read the news on this incident but somehow your conclusion was way off the mark.My comment was on the conclusion drawn by yourself on this incident of "Grid Collapse"

oh i see Indians are trying to compete with us

I haven't heard on this forum that the Pakistani grid collapsed and you guys are out in the dark.

sound more like Load shedding to me (load shedding and why is it carried out?)

You can make it sound whatever you want.
States have to come up with a 1 week schedule how much power is required by them and the load centre allots the power quota according to the power requirements put forth by the state keeping in mind the constraints.But if you start over drawing because the State Electricity Board failed to calculate the demand then the load balancing system is disturbed,as the infrastructure has limits on it and the state is penalised for overdrawing.
If the load centre has a deficit in Availability and demand then it ask the Electricity Boards to go for Load Shedding.

I suppose you guys have frequent Grid collapses

This sounds more like a brain fart.

Power failure: How a grid works, and when it doesn’t​

What is an electrical grid?

A grid is an interconnected network of transmission lines and substations hooked on to generating stations on the one hand and load centres on the other. The generating stations, put together, supply the electricity demand through the transmission lines; the load centres or distribution companies then draw the power from the lines and wheel it to consumers. The basic premise for the stability of the grid is that load and generation must be balanced at all times to prevent a failure. The flow of electricity through the lines should ideally not exceed the rated capacity, otherwise the lines could trip due to an overload. For grid operators, one of the prerequisites is to ensure that there is adequate redundancy in the system so that the possible tripping of one line does not lead to a cascading event that can potentially impact operations of the grid as a whole.

What are a grid’s components?

A grid consists of three main components: power stations that produce electricity from fossil fuels (coal, gas) or non-combustible fuels (hydro, nuclear, wind, solar); transmission lines that carry electricity from power plants to demand centers; transformers that reduce the voltage so that distribution lines carry power for final delivery.

What happens in an ideal situation?

All generating stations are expected to inject power as per schedules declared by them to the grid operator while all load centres or distribution utilities are expected to draw power as per the drawal schedule given by them to load despatch centres.

How does one know if a grid is stable?

This is done by monitoring the grid frequency, an index that shows whether power is being supplied and drawn as per schedule. The optimal frequency in India is pegged at 50 hertz, or cycles per second. The permissible frequency band for grid operations in India is 49.5Hz to 50.2Hz, as per the Indian Electricity Grid Code. The larger the grid size, the more stable it is deemed to be. At the same time, if a grid disturbance does happen, its scale could be larger for a larger grid.

What is the disincentive against overdrawing?

There cannot be physical control over excess drawal, only a financial penalty. In India, the grid frequency-linked penal measure is called the Unscheduled Interchange or UI rate. If the grid frequency drops, the UI rate shoots up, acting as a disincentive for discoms to overdraw when the frequency dips.

Does the penalty serve its purpose?

Northern states are repeat violators of the grid frequency norms, especially Uttar Pradesh, Haryana, Punjab, Jammu and Kashmir. The ‘UI’ penalty has failed to deter some of these states, which overdraw and then default on the ‘UI’ payment itself with the grid operators. UP, for instance, is known to routinely run up ‘UI’ bills of several hundred crores and delay the payments. The state has also taken advantage of a High Court order under which it does not pay the full UI penal rate.

When does a grid collapse?

There can be two main reasons. One is equipment failure due to reasons such as fog and pollution, as had happened when the northern grid collapsed in 2002. The other, and more common, reason is when one or more constituents violate the grid code and overdraw in a big way from the grid, causing it to fail due to the imbalance in the power injection and drawal patterns, as seems to be the case in Monday’s northern grid collapse.

What is the network in India like?

At present the northern, western, eastern and northeastern regions are integrally connected through AC (alternating current) transmission links to form what is called the ‘NEW’ grid. There is a free flow of power between these four regions. The southern region is hooked up with the rest of the country through HVDC (high voltage direct current) transmission links, which have constraints on wheeling capacity, thereby limiting the free flow of power from and to the southern region. India’s current cumulative installed capacity is 205 gigawatts (1GW is 1,000MW).

Are grid failures an Indian phenomenon?

Not really. While India has seen two major grid failures in the last 10 years, there have been several instances of grid collapses in other parts of the world. These include the Brazil-Paraguay blackout of 2009 that affected 87 million people, the Northeast blackout of 2003 in North America that affected some 55 million residents, the 2003 Italy blackout that hit another 55 million people, and the 2005 Java-Bali blackout, by which close to 100 million people were affected in Indonesia.

Problem with electricity India has is transmission and storage, not generation.

For example, At times its more economical to export electricity, generated in Northern India to Pakistan than transmit to some place in Southern India

Maybe some members can add more information.

 

[Kesang]

I think that Today is most hottest day of year 2012 and we didn't received power for even 1 hour in daylight.

But now everything is fine because power came back

Guys I have a question - If India is suffering from electricity shortage then why India wants to export electricity to Pakistan?Doesn't make any sense.

It is not about electricity shortage. Grid failure is a complete technical term. The problem arose when some of our states drew power beyond the limit pulling the grid frequency below the limit. Minimum and maximum allowable frequency is 47.5 and 52.5Hz. When one region draws excessive power due to protection of the entire grid, the particular faulty region gets isolated to save the other healthy regions. This one possibly happened here too with a massive coverage of area.
We are used to total power failure, which can be caused by many possibilities, mostly due to transients caused by lightning,but those are limited to a small network unlike these two instances. you can see what happened today to calcutta Electric Supply Corporation (Power generation and distribution company in kolkata). They have their own generating station and own transmission network too. At 13:02PM to be exact, when the failure occurred its protection system sensed the low frequency and isolated itself from the entire grid; thats why kolkata did not face too much trouble today.
lastly, hats of to our engineers, who restored the power within 2.5 hours.

I'm not sure. But if I remember correctly, given the large size of the country, transmission costs will make it unviable to move it from one grid to another. But given the proximity of pak, India could sell electricity while incurring relatively lower transmission cost, make a quick buck or two and from a diplomatic standpoint, make pakistan look dependent and weak.

Feel free to correct me if i'm wrong.

Live: Northern, Eastern grids restored partially - India News - IBNLive
New Delhi: Updates: Union Power Minister Sushil Kumar Shinde has put the blame of the grid failure on the states that have been over drawing power. He said, "We had warned several states about overdrawing of power. So we had to face second grid failure in less than 24 hours."
He also warned the states against overdrawing electricity above their limits, saying, "If states overdraw from their regular quota, they will be penalised."
Talking about the power restoration, Shinde said that while 44 per cent had been restored in north, in east it was 35 per cent. The situation is best in North East with 100 per cent power restoration.
In the national capital, Shinde said, that essential services were now back on track.

[sarthak]

India is a third world country. With a lot of hype around how we can compare to China but with 1/10th of China's potential. I know all of us have national pride but its time to ask ourselves just what this country is giving us. If it cant even guarantee us a basic quality of life then why should we continue our pride. And has the current government done anything to improve the situation. Shinde should be fired, he keeps giving false assurances which shows how much he knows. Someone who worked at the Grid sai d this time it could take weeks to resolve.

LOL , here comes a self appeasing chinese. Did you mom tell you you have ten times our potential? Fact is you people have a GDP per capita less than many african nations. If not for your massive population , your country is just crap. And anyway , China is still considered a third world country. Most of your population , especially in villages lives in squalor and extreme poverty
