Oscillation is, to be precise, the out-of-step oscillation of the power grid, which is the most serious accident in the power grid. Simply put, all parameters of the power grid are almost stable, so that each unit of each power plant can generate and supply power at the same speed. Just like a balance, or a swing, it must be completely consistent up and down, left and right, with the same pace, and maintain a relatively balanced power grid. Now, for some reason, this balance is roughly broken, the balance begins to deflect, and the swing begins to lose control.

To put it more vividly, a normal power grid is like the tide of the sea, with stable voltage, small fluctuations in frequency, ebb and flow, gentle and elegant. When a serious accident occurs in the network, when a large-capacity power plant suddenly loses control, it is like in an instant, the entire Pacific Ocean is suddenly drained, and the sea water of the other three oceans must roar with a surging momentum. The tsunami generated cannot be calmed for a long time. Although this is impossible in reality, such things will happen in the power grid. The oscillations caused by the power tsunami are also terrible destructive.

What is the final result?

In modern power grids, every power plant in the access network is like dominoes. Faced with sudden oscillations, its generator will also fluctuate and fluctuate accordingly, and face the risk of shutdown. This is how the chain effect occurs. Oscillation causes more and more power plants to trip, and trip causes the power supply gap to increase, causing more violent oscillations. A series of dominoes face collapse, power supply losses are rising, and the power outage range is rapidly increasing, and it may eventually be so large that even dispatchers cannot control it.

And when the dominoes collapse one after another, if there is a card in the middle that holds it and does not fall, the incentive for the power grid is huge. It is like erecting a tall and strong embankment before the tsunami, forcing the tide with one's own strength to fight against the tide. If the dam can be stabilized, it will not only oscillate stably, but also give the dispatcher more time to adjust the power grid to save the balance and swing.

Zhang Yifu dared not think further. Whether it was the collapse of the balance or the derailment of the swing, it was the entire regional power grid. It was something that the current Jibei Power Plant could not bear. Just finished the safety production meeting and just emphasized the safety issues in the second week, the entire North China Power Grid was at the forefront.

Is this someone else’s problem? Yes. Does it have nothing to do with yourself? No.

The Jibei Power Plant is at a critical moment of applying for compliance. If it is implicated by other power plants, the shutdown will eventually be part of the accident and will slow down the application time for compliance. Furthermore, if an accident occurs in the North China Power Grid, all power plants in the network may be affected.

With one move, one falls again and another, and three out. Everyone is in the mood to fight for honor. This kind of accident happened, and a basin of cold water was poured down. All efforts became a bubble.

To go further, now I and Huang Hongbin are working so hard to reduce coal consumption, isn’t it just for fame and merit? If this accident is a big deal, who will still praise you? No matter how many achievements you have, an accident will be enough to completely erase it. This is the cruel fact that the power system and the power people have to face.

After a few seconds, more and more people realized the seriousness of the situation.

"Gen...Gengen according to the dispatching procedures...we must report the dispatch as soon as possible..." The shift leader on duty picked up the phone receiver in a trembling voice and pressed the four-digit extension number tremblingly.

Three seconds later, he looked at Zhang Yifu in complete confusion: "I can't hit it..."

At this time, it will definitely not be able to be completed. Some other power plants must have found something wrong.

I guess the dispatcher has no time to figure out what's going on. Even if he figures out, in the face of this kind of oscillation, he must first pull the switch to limit the power and reduce the load, and then according to the situation, one home appliance factory notifies him to come over to control it, and the daylily is cold.

Zhang Yifu tried his best to calm himself down, and after he clarified his thoughts as quickly as possible, he rushed to the duty commander and said, "Distribute two units, hurry up."

"What? Disassembly?" The squad leader was shocked.

Zhang Yifu's first decision was very simple, that is, to de-order directly, that is, shut down.

Judging from the instrument data of the Jibei Power Plant, I am undoubtedly on the side with more power, that is, the side where the balance is pressed down and the side where the swing is flying.

To restore the balance to balance, and to prevent the swing from flying, you can only survive by breaking your arms.

Directly shutting down the unit, reducing power, and calming the oscillation is the most direct and effective method.

But at the same time, this responsibility is also huge.

"Remove the line... This must be dispatched and ordered." The squad leader said, wiping his sweat.

"The accident has happened for 20 seconds! It would be too late if I don't get out of the line!" Zhang Yifu looked at the dial and said, "I'm responsible for everything, you can do it boldly."

"No...this is absolutely not possible..." The squad leader gritted his teeth and said, "Team Leader Zhang, the accident had nothing to do with us. If you act so self-righteously, you might be used to make a case for it, and you will definitely not be dismissed."

"It's too late!" Seeing the squad leader's appearance, Zhang Yifu obviously did not dare to do such a decisive thing, so he had to settle for the second best, "In this way, immediately reduce the effective output of all units, increase the reactive output of the unit, and raise the bus voltage, quickly!"

"Reduce power and raise voltage?" The squad leader on duty was shocked, and beads of sweat were soaked out, "This... this has to be ordered by the dispatcher..."

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

"But at least... at least the factory director has to order. We don't have this power," the shift monitor muttered in a trembling voice: "Dispatch procedures...safety regulations..."

"Damn it, what's the matter? I'm responsible!" Zhang Yifu shouted, "Even if you dispatch a message, you have to deal with it. This is an effective way to calm the oscillation!"

"No...can't do this." The shift leader on duty still shook his head firmly, "This does not comply with the regulations, so I need to ask for instructions on dispatching."

The shift leader on duty picked up the phone in panic and dialed the dispatching extension again, without a doubt, still busy.

Zhang Yifu clenched his fist hard, would he do it with his own hands?

No. He is not qualified to operate. This is the dead law of the power system. He is not a certified duty officer. No one can operate the console. Niu Dameng cannot come, nor can the minister come, nor can he Zhang Yifu.

"Don't wait for the dispatch! This measure is not so responsible. Do what I said. I will be responsible for everything!" Zhang Yifu had no choice but to continue urging the on-duty squad leader, "This operation is completely in line with the regulations!"
