Trinidad Blackout (16 Feb 2022)

[bluefete]

marvy report say wires from one circuit bust and fall on a next set of wires causing a short out
how they preventing this in future

People really believe this? Really?

Carry on then.

Only stupid LFD RFD like Colos,wing and mero

[bamfo_dennis]

so wha but d explosion dat was confirm by ppl who was in d place?
me eh read nuthin bout explosion in d papers yet.

Eh?

[st7]

current gone in chaguanas area.

not sure if another blackout again lol

Well that rain that fell may have contributed.

On Tuesday February 22nd 2022, the Acting Prime Minister Colm Imbert in fulfillment of the Government’s commitment which was given in the Parliament on Friday February 18th, 2022, issued letters of appointment to members of the Committee appointed to investigate the cause of, and national response to, the island wide power outage which took place on Wednesday February 16th, 2022.

^^

Anybody have a copy of the report ..

Another waste of $$$$

[pugboy]

committe is level 1

so when is the commission of enquiry into this?

[De Dragon]

This report will end up like Niquan etc, tucked away safely in JUHN Scarfy cacahole

[daring dragoon]

anyone getting dips in the current? lights flickering, etc. general low voltage situation.

Where?

[daring dragoon]

north trinidad.

[eitech]

So it was a tree after all..and some other systems failed as a consequence of said tree

[st7]

anyone getting dips in the current? lights flickering, etc. general low voltage situation.

i been noticing spikes the last few weeks (chaguanas area).

[Kenjo]

Hmm I’ll look at my surge protector voltages

[mamoo_pagal]

anyone getting dips in the current? lights flickering, etc. general low voltage situation.

i been noticing spikes the last few weeks (chaguanas area).

Yea, I had to call them this week. Voltage spiking to 312V, not a one off event

You should call Fires Services and tell them wet man to be on stand by Mamoo

THE REPORT ON TO NATIONWIDE BLACKOUT BLAMES A FALLEN TREE AS THE CULPRIT.

THE REPORT WAS COMMISSIONED BY THE GOVERNMENT AND INVOLVED A 3-MAN INVESTIGATIVE TEAM.
THE MEMBERS OF THE TEAMS:

1. CHAIRMAN—PROFESSOR CHANDRABHAN SHARMA (RETIRED PROFESSOR OF ELECTRICAL AND COMPUTER ENGINEERING

2. MEMBER-- MR. KEITH SIRJU (FORMER T&TEC CHAIRMAN)

3. ACTING SUPERINTENDENT OF POLICE ALLISTER GUEVARRO

IN THE 70-PAGE REPORT, THE CAUSE OF THE WEDNESDAY 16THG FEBRUARY, 2022, NATIONWIDE BLACKOUT, LISTED A ROTTING PALMISTE TREE THAT FELL ON A T&TEC POLE AT GRANTS TRACE EXTENSION ROAD, ROUSILLAC. ACCORDING TO THE REPORT, THE TREE FELL BECAUSE OF HIGH WINDS IN THE AREA.

THE REPORT LISTED THE INCIDENT AS AN ACCIDENT ADDING THAT THERE WAS NO EVIDENCE TO SUGGEST THAT THERE WERE CRIMINAL ACTS OF SABOTAGE SURROUNDING THE INCIDENT

ALSO SAID THAT T&TEC WAS THE ONLY STATE AGENCY THAT PROVIDED UPDATES TO MEMBERS OF THE PUBLIC WHO WOULD HAVE BEEN GRAVELY AFFECTED BY SUCH AN INCIDENT.

ACCORDING TO THE REPORT, THERE WAS A LOW PROBABILITY OF A REOCCURRENCE BUT THERE ARE SEVERAL FACTORS THAT CAN CAUSE ANOTHER NATIONWIDE BLACKOUT.

IT ADDED THAT NONE OF THE STATE ENTITIES WERE PREPARED FOR OR ANTICIPATED THAT A NATIONWIDE COULD HAVE BEEN A NATIONAL DISASTER.

[agent007]

We need to come together as a nation and protect all surrounding trees and ttec poles in Rousillac cause another affected pole due to rotting tree can send us back into the stone age for another 12hrs.

[timelapse]

Next new reveal:
The Paria divers deaths were as a result of this same tree.Story has it that the tree is a descendant of the tree that Gang gang Sara flew off in Tobago when she cursed the place.

[bluefete]

One tree caused a nationwide blackout. One tree.

[Duane 3NE 2NR]

A tree!
This really is not a real place

[Chimera]

Mc palmiste tree.

They need to chop down and burn all palmiste trees. Burn down all areas that have palmiste in the name and kill everyone who lives there to be safe

[wingnut]

Wow imagine that a whole country grind to a halt cus of one tree, no redundancy built into such a critical infrastructure. Management needs to be held accountable

[agent007]

Alluh really expect the government to come and tell the nation the truth and advertise a major national security weakness?

If hackers wanted to truly disrupt trini businesses, all they need to do is cut a tree down rousillac and there you go but you see hackers smarter than that. They know a tree can't do that.

[maj. tom]

A tree!
This really is not a real place

But it makes sense though because the lines that it took down were carrying huge loads on a 12kV and then a 220kV, which was immediately redistributed which caused all the breakers to trip. This is not so amazing and unbelievable.
If you look here https://en.wikipedia.org/wiki/Northeast_blackout_of_2003#Sequence_of_events you will see that several events in the sequence of failure were caused by sagging lines and trees.

1. The Palmiste tree eventually fell off the 12 KV line causing the line to sag, oscillate and upswing, and to come into contact with the 220KV line circuit, which transmits most of the power from the TGU generating facility to T&TEC. The 12 KV line crosses orthogonally under the 220 KV transmission by a distance of over four (4) metres, which is more than two times the minimum stipulated by international standards.

2. The fault occasioned by the two lines accidentally coming into contact with each other caused the protection relays on the two circuits on the 220 KV transmission line to trip sequentially and become de-energised thereby isolating the TGU plant from the grid.

3. The de-energizing of the 220 KV transmission line, created a large imbalance between available running generation supply (537 MW) and load (68.75 MW) resulting in a very rapid increase in generation speeds at the TGU plant, as the essentially unloaded turbines accelerated. The turbines immediately tripped on over speed protection, disconnecting all generators at TGU thereby resulting in a 47% loss of generating capacity.

4. The sudden loss of 47% of generating capacity on the grid was too fast for the system’s circuit breakers to shed load to match the available generation. In the circumstances, the other IPPs experienced underspeed and under-frequency conditions which exceeded their stability limits leading to a cascading outage and the collapse of the entire electricity grid, first at the Point Lisas plants and then at Penal.
https://trinidadexpress.com/newsextra/c ... 73038.html

The conclusion and recommendations of the report should be that the Grid has to be upgraded to a "smart" system where the computers can react faster and redistribute load using intelligent programming with redundancies so that a nation-wide failure wouldn't occur again, and try to limit it to 1 or 2 sectors.

[De Dragon]

LFD RFD PNM supporters taking this without question.

So the load sharing on our power generation network is so unpredictable in 2022 that we have to worry that a tree will knock us off. Oh well at least we are not Texas!!!
