Oscillation, to be precise, is an accident in which the power grid is the most severe. To put it simply, almost all parameters of the normal operation of the power grid are stable, so that each unit of each power plant can stabilize electricity and power supply at the same revolution. Just like a scale, or a swing, it must be exactly the same up and down, left and right, at the same pace, and it is safe to maintain a relatively balanced power grid. And now, for some reason, this balance is rudely broken, the scales are starting to skew, and the swings are starting to get out of control.

Figuratively speaking, the normal power grid is like the tide of the sea, the voltage is stable, the frequency fluctuates slightly, the tide rises and falls, and the gentle and elegant, and when there is a strict zhòng accident in the network, suddenly a large-capacity power plant is out of control, just like in an instant, the entire Pacific Ocean is suddenly drained, and the sea water of the remaining three oceans will roar with a monstrous momentum, and the resulting tsunami can not be calmed down for a long time, although this is impossible to happen in reality, but in the power grid, such a thing will happen, and the oscillation caused by the power tsunami also has terrible destructive power。

What is the end result?

In the modern power grid, every power plant in the access network is like a domino, in the face of sudden oscillation, its own motor will also oscillate and fluctuate, facing the danger of shutdown, the chain effect is generated in this way, the oscillation trips more and more power plants, and the trip leads to the increase of the power supply gap, resulting in more violent oscillation, a series of dominoes face collapse, power supply losses are rising, the scope of power outages is rapidly increasing, and eventually it may be so large that the dispatch can not control the program.

And at the time of the collapse of this domino one after another. If there is a card in the middle that holds up and does not fall, then the encouragement to this grid is huge. If the dam can be stabilized, it will not only stabilize the oscillation, but also buy more time for the dispatcher to adjust the power grid to save the balance and the swing.

Zhang Yifu didn't dare to think about it anymore. Whether it's a balance collapsing or a swing derailing, it's the entire regional power grid. All of them are unbearable for the current Jibei Power Plant. Just after the safety production meeting, just emphasized the safety of the second week, the entire North China Power Grid is on the cusp.

Is this someone else's problem? Yes. Isn't that irrelevant? No.

The Jibei Power Plant is at a critical moment in applying for the standard, if it is implicated by other power plants. The shutdown is ultimately part of the accident and will slow down the time for compliance applications, and if there is an accident in the North China Power Grid, all power plants in the network may be affected to meet the standards.

One blow, then decline, three and exhaustion, everyone is fighting for honor, this kind of big accident, a basin of cold water poured down. All the hard work was in vain.

Going deeper, isn't it just for fame and merit that Huang Hongbin and Huang Hongbin are working so hard to reduce coal consumption? Who has the heart to praise you? No matter how many merits you have, one accident is enough to completely wipe them out, and this is the cruel fact that the power system and the power people have to face.

As the seconds passed, more and more people realized the severity of the situation.

"Root...... Gengen is ...... according to the scheduling procedure It is necessary to report to the dispatch ...... as soon as possible" The shift leader on duty picked up the telephone receiver in a trembling voice and pressed the four-digit extension number tremblingly.

Three seconds later. He looked at Zhang Yifu completely confused: "Hit ...... It doesn't work. ”

At this time, it must be impossible to get through. There must be other power plants that are not right now.

It is estimated that the dispatcher himself has not had time to figure out what is going on, even if he does, in the face of this kind of oscillation, he must first pull the power rationing and load reduction, and then according to the situation, a household power plant will notify how to control it, and the daylily is cold.

Zhang Yifu tried his best to calm down, and after clearing his thoughts as quickly as possible, he said to the squad leader on duty, "Untie the two units, quickly." ”

"What? " The class leader was shocked.

Zhang Yifu's first decision is very simple, that is, to directly detrain, that is, to shut down.

Judging from the number of meters in the Jibei Power Plant, his side is undoubtedly on the side with more power, that is, the side where the balance is pressed down, and the side where the swing is pushed up.

To balance the scales, let the swing not swing, only to survive with a broken arm.

Directly shut down the crew, reduce the power, and calm the oscillation, which is the most direct and effective method.

But at the same time, the responsibility is enormous.

"Unlisted...... This must be ordered by scheduling. The squad leader wiped his sweat and said.

"It's been 2o seconds since the accident happened! If you don't solve it, it's too late!" Zhang Yifu looked at the dial and said, "I'm responsible for a qiē thing, you boldly operate." ”

"No...... This is definitely not good......" The squad leader gritted his teeth and said, "Team Leader Zhang, the accident has nothing to do with us, you are so self-assertive, you will not be used to talk about things, and you must not be dissolved." ”

"It's too late!" Zhang Yifu saw the appearance of the squad leader, obviously did not dare to do such a decisive thing, he had to retreat to the second, "In this way, immediately reduce the active output of all units, increase the reactive output of the unit, and raise the bus voltage, fast!"

"Drop the power, raise the voltage?" the shift leader was shocked, and beads of sweat the size of beans oozed out, "This ...... This also has to wait for the dispatch to order the ......"

"It's too late, hurry up!" Zhang Yifu scolded loudly.

"At least...... At least we have to give the order of the factory director, we don't have this authority," the shift leader muttered in a trembling voice: "Scheduling procedures...... Safety Specification ......"

"Damn, shrug something, I'm responsible!" Zhang Yifu shouted, "Even if it's scheduling, it has to be handled like this, this is an effective way to calm the oscillation!"

"No...... It can't be like this. The shift leader still shook his head firmly, "This is not in accordance with the regulations, you have to ask for dispatch." ”

The shift leader picked up the phone in a panic and dialed the dispatch extension again, and there was no doubt that the line was still busy.

Zhang Yifu clenched his fists fiercely, do you want to operate it yourself?

Not good. He is not qualified to operate, this is the dead law of the power system, non-licensed duty officer, no one can operate the control platform, Niu Dameng is not good, the minister is not good, and he Zhang Yifu is not good.

"Don't wait for the dispatch! This measure is not so responsible, do as I say, I will be responsible!" Zhang Yifu could only continue to urge the shift leader, "This operation is completely in line with the regulations!"

After Zhang Yifu scolded, he recalled that under special circumstances, at the critical moment of the power grid, the regulations on reporting after adjusting the output may have been introduced in a few years. The rules, the rules, are all refined from the lessons of blood. (To be continued)
