The monitor of the electrical duty room this time was Ye Qingqing, who participated in the national competition, who was in the hall and in the kitchen, and with a nervous and excited mood, she called the dispatch room of the North China Electric Power Management Bureau.

"I am the dispatcher of North China xxx. Jibei Power Plant. According to the dispatch plan, you will operate Line 3 of your factory at exactly 10 o'clock, switch from busbar 1 to busbar 2. Please be prepared for operation."

As the power amplifier was turned on, the young dispatcher on the opposite side heard a chanting voice. Ye Qingqing immediately said in standard Mandarin: "I am Ye Qingqing, the duty officer of Jibei Power Plant. It is planned that our factory will switch Line 3 from busbar 1 to busbar 2 at 10 o'clock, and we are ready for operation." According to the rules, the duty officer needs to repeat the dispatching instructions in Mandarin.

"Okay, please wait for the operation instructions."

When you hang up the phone, you have to go out of your pants and fart when you have agreed to take off your pants and fart them. Therefore, even if it is a simple command, you have to answer the phone several times and follow the most standard and boring process.

This process was very disgusting. Other leaders were too lazy to watch it carefully and just chatted. However, Ye Qingqing's performance could not stop. Zhang Yifu was on the side and did not dare to devote himself to chatting. As the saying goes, those who drowned are all watery. You must keep a good eye on it and move forward carefully in the gutter!

A few minutes later, the phone rang again, and the North China dispatcher issued an order to connect Line 3 to busbar 2. After a simple operation, Line 3 connected to busbar 2. In other words, Line 3 was connected to two busbars at the same time, and his son finally took the hands of his father and mother at the same time.

I took off my pants and started farting.

Ye Qingqing called the dispatcher immediately: "I am Ye Qingqing, the duty officer of Jibei Power Plant. North China dispatcher. Jibei Power Plant has completed the operation of Line 3 connecting busbar 2. Now Line 3 connects busbar 1 and busbar 2 at the same time."

"Okay, I am the North China dispatcher xxx. Please wait for the dispatch confirmation and wait for the dispatch instructions."

After the conversation, the phone was hung up, Ye Qingqing was a little confused. Our power plant was doing a show here in a regular manner. How did your dispatch room perform even better than us? You always ordered the disconnection between Line 3 and Bus 1? Can't you just let the child loosen his mother's hand? You still had to hang up the phone and confirm and order again. Is this fart too much?

Looking back, the leaders were still chatting and laughing. Ye Qingqing had to wait like this.

Although there was basically no pressure, the waiting process was still very painful. Ye Qingqing did not dare to continue the subsequent movements without dispatch, so she had to keep sitting upright and smiling.

But she smiled and suddenly couldn't laugh.

Electrical duty room. One of the most intuitively observed parameters is the power, or load, the power sent by each line, or called load. The power emitted by all units in the factory is collected on the bus line. Then it is sent out through several lines on the bus line. Some lines are merged into the regional power grid to supply the load of the province. Some lines are connected to the hub substation and sent to other provinces and cities, especially to provide power for Jijing. Under normal circumstances, there is no fault or planned operation of the line, and the power transmitted by these lines should be a normal and stable parameter, unless the power grid oscillation occurs like the last time when the incident occurred in Fengzhou, and there will be severe fluctuations.

And this time, an even more exaggerated phenomenon occurred.

Ye Qingqing was a little surprised. She clearly saw that the power of one of the factory lines dropped to zero.

In an instant, she forgot to breathe, and just rubbed her eyes with her breath, and then looked closely. There was no fluctuation in the pointer on the power dial, it was zero.

In other words, a certain qualifier is in a state of disconnection.

Ye Qingqing turned his head to the right line switch state as soon as possible - it was right in the closing position.

Is there something wrong with the transmission line? Or is there something wrong with the monitoring in the duty room?

Ye Qingqing was no longer as surprised at this time, and her entire soul seemed to be drained instantly. The matter of meeting the standards passed five levels and six generals, but now she was trembling for the last time. No matter what, she couldn't have any accidents in her hands. She subconsciously turned her head and looked at it with her eyes. The leaders' focus was not here, and she had not found any abnormalities on the dial.

Without any extra thought, she moved the chair and completely blocked her body in front of the dial.

At this time, the on-duty officer sitting next to him also noticed the abnormal movement and stared at him and said in a silence: "Squad leader... this?"

"Shh..." Ye Qingqing glared at her eyes and immediately made a gesture to stop, "You sit here and I will deal with it."

"..." The on-duty officer swallowed and spitted, and finally realized that his soul was half scared away.

This line leads to the Hebei substation and it stopped for no reason...

It is not impossible to stop. If it is line maintenance or something, the dispatching can be stopped after the dispatching is arranged. The opposite side can operate first, but the dispatching has not given any notification or arrangements at present. Moreover, the Jibei substation was just inspected before the New Year, so it is impossible to be so frequent.

Could it be that something is wrong with my factory? The wire is broken? The switch is wrong?

OMG……

When will it not work for 365 days a year? Why is it now!!

According to regulations, if you find this situation, you must report to the dispatch as soon as possible and then check the equipment. However, if you follow the regulations, this simple practical assessment will become complicated... In case something really happens in the factory...

No one dares to be this sinner.

Like Ye Qingqing, the young duty officer also subconsciously turned back to the leaders.

This look was not good, and it happened to meet Qin Yong.

"Oh? How is it?" Qin Yong raised his eyebrows and asked, "Has the dispatcher ordered?"

After being asked by the chief director, the young duty officer immediately panicked and could not say a word.

Even Ye Qingqing calmed down and turned around and said, "I'm still waiting for further instructions from the dispatch."

"Take it over." Qin Yong didn't notice anything unusual, and waved his arm, "This is an assessment of you, not a scheduling test. Be realistic and strive for efficiency."

After saying that, he turned to Zhao Wenyuan: "Director Zhao, we have also seen the rigorous dispatch of North China. Isn't it a violation of regulations to urge like this?"

"Not counted." Zhao Wenyuan nodded and smiled, and said to Ye Qingqing, "Contact and contact. Director Qin has spoken. If there is no problem, please disconnect the line from the busbar i."

"Okay." Ye Qingqing responded with breath, and then ordered the on-duty officer next to her to sit in her seat to contact the dispatcher. She stood up and winked at Zhang Yifu.

Zhang Yifu kept staring there. Although he didn't see the change in the dashboard, judging from Ye Qingqing's eyes, something might have happened.

He didn't dare to think too much, so he quickly stopped talking and moved to the corner of the duty room.

Ye Qingqing also withstood the pressure and pretended to come over as if nothing had happened.

Her face was pale at this time.

"Yifu... No. 5 has stopped qualifying..."

"No. 5?" Zhang Yifu swallowed and spitted, his brain was also blank. "Line 2911? Going to the Jibei substation?"

Ye Qingqing Zheng nodded in a key position: "I didn't dare to say it...what should we do it?"

Zhang Yifu gasped, and he was afraid of anything he was afraid of. How could such a trouble pop up at the last moment of meeting the standards? You should know that power plants that have had accidents within a year cannot apply for compliance. Even if a power plants meet the standards have an accident of a certain degree, they will face the punishment of delisting, just like Fengzhou.

Of course, Fengzhou has no right to choose, it’s just that unreasonable. Something happens is something that happens, and it is a big thing that the entire network sees.

However, in the current northern Hebei, Zhang Yifu is facing a terrible multiple-choice question.

If this matter is reported now, it may not be a matter of the factory and has nothing to do with the actual assessment, but it is also possible that there is a problem in the factory, an accident, a line is damaged, and a switch is faulty. If it is normal, you may think of a way to communicate well with the bureau and make big things small. But now the leaders in the bureau are all there, and once this matter is reported, it will not be regarded as a small matter.

Even though the leaders are very tolerant, when encountering such a thing during practical operation, as long as the matter is related to the power plant, I am afraid it will be over.

So what if you don’t report it? The bureau’s dispatcher may be able to discover it yourself soon.

The line is disconnected, and there is one less power supply line at the Jibei substation.

The function of a substation is similar to that of an ultra-large transformer. It is to change the voltage. Ultra-high voltage is required to transmit power for a long distance, high voltage is required to supply power within the grid, and the voltage requirements for local power supply are lower. Substations are to change the power obtained from the power grid and power plants into these power sources of different orders of magnitude.

As a substation in northern Hebei, it has three functions.

One is a checkpoint and a hub for the northern power grid of Hebei Province.

The second is to allocate local loads to provide power for production and life.

Third, it is also the most important political sense. The power from the power grid in northern Hebei is boosted and transmitted to Jijing through ultra-high voltage transmission lines to supply the capital's power demand.

Ensuring power supply to the capital is almost always the top priority of the North China Power Grid and North China Bureau’s work tasks.

As a direct connection with the Jibei Power Plant, Jibei substation undoubtedly played an important role in this task.

Now this line is broken...

Although there are other lines and other sources of electricity in and out of the Jibei substation, if you don’t have such a big speed, you may have entered a precarious state. The transmission load of each line of the substation is limited. The line in Jibei is gone, but the power supply and demand still exist, and the grid frequency is still the same. For other lines, there is a very likely overload condition. There may be no obvious signs in a short period of time, but once the overload time is long, the line will be damaged. The lines that were originally hanging in the air will hang down like ramen noodles...

This kind of grounding failure and line tripping and circuit breaking accidents caused by this "ramen noodles" are common in the industry.
