The squad leader of the electrical duty room this time was Ye Qingqing, who participated in the national competition, and she was nervous and excited to connect the phone of the dispatching room of the North China Electric Power Authority.

"I'm North China dispatcher xxx. Jibei Power Plant, according to the scheduling plan, will operate the No. 3 line of your plant at ten o'clock, switch from bus 1 to bus 2, please be ready for operation. ”

Gong let go, and the voice of the dispatcher young man on the opposite side came from the recitation. Ye Qingqing immediately said in standard Mandarin: "I am Ye Qingqing, the attendant of the Jibei Power Plant. At ten o'clock, our factory will switch the No. 3 line from bus 1 to bus 2 and is ready for operation. According to the regulations, the attendant needs to recite the dispatch instructions in Mandarin.

"Okay, please wait for the instructions. ”

When the phone is hung up, it is said that if you take off your pants and fart, you must take three steps - take off your pants, fart, and put on your pants, so even if it is a simple command, you have to hang up the phone several times and go through the most standard and boring process.

This process is very disgusting, the other leaders are too lazy to watch carefully, they only care about chatting, but Ye Qingqing's performance can't stop, Zhang Yifu doesn't dare to devote himself to chatting on the side, as the saying goes, those who drown know water, they must keep an eye on it, and move forward carefully in the gutter!

A few minutes later, the phone rang again, and the North China dispatcher gave the order for Line 3 to connect to Bus 2, only to see that after a simple operation by Ye Qingqing, Line 3 was connected to Bus 2. That is to say, the No. 3 line took two bus wires at the same time, and the son finally took the hands of his father and mother at the same time.

I took off my pants and started farting.

Ye Qingqing dialed the dispatch phone as soon as possible: "I am Ye Qingqing, the duty officer of Jibei Power Plant. North China Dispatch. Jibei Power Plant has completed the operation of connecting bus 2 with line 3, and now line 3 is connected to bus 1 and bus 2 at the same time.

"Okay, I'm North China dispatcher xxx. Wait for the scheduling confirmation and wait for the scheduling command. ”

After that, the phone hung up, Ye Qingqing didn't understand a little, our power plant is putting on a show here, how can you play better than us in the dispatch room? Can't you just order to disconnect Line 3 from Bus 1? Can't you just let the child let go of his mother's hand? I have to hang up the phone, confirm and give an order again, this fart is too pretentious, right?

Looking back, the leaders are still talking and laughing. Ye Qingqing had no choice but to wait.

It's basically not stressful though. However, this waiting process was still very tiring, and Ye Qingqing did not dare to continue the actions without the dispatch order, so he had to sit upright and smile.

But she smiled and laughed, and suddenly she couldn't laugh anymore.

Electrical duty room. One of the most intuitive parameters to observe is the amount of power delivered by each line. Or it's called a load. The power output of all units in the plant is pooled into the bus. Several lines on the guò bus are then sent out, and some lines are connected to the regional power grid to supply the province's loads. Some lines are connected to hub substations and sent to other provinces and cities, especially to provide electricity to Jijing. Under normal circumstances, there are no faults and planned outages of line operation, and the transmission power of these lines should be a normal and stable parameter, unless there is a grid oscillation like the last Toyoshu accident, there will be violent fluctuations.

And this time, an even more exaggerated phenomenon appeared.

Ye Qingqing was a little stunned, she clearly saw that the power of one of the factory lines had dropped to zero.

In an instant, she forgot to breathe, only held her breath and rubbed her eyes, and then looked at it again, and the hands on the power dial did not fluctuate at all, it was zero.

In other words, an outgoing line is in a broken state.

Ye Qingqing turned his head to the appropriate line switch state for the first time - it was in the closing position.

Is there a problem with the power lines? Or is there simply a problem with the monitoring in the duty room?

At this time, Ye Qingqing was no longer so surprised, and the whole person's soul seemed to be drained in an instant. After passing five levels and cutting six generals to meet the standard, now it is the last trembling, and no accident can be made in his own hands no matter what. She subconsciously turned her head sideways to probe with her peripheral vision, and the leaders' focus was not here, and there was no abnormality in the dial.

Without any extra thought, she moved her chair so that her body was completely in front of the dial.

At this time, the attendant sitting next to him also showed this abnormal movement, and said dumbly with his eyes: "Squad leader...... This?"

"Shhhhh......h ”

The "......" attendant swallowed and spitted, and finally reacted at this time, and the soul was half scared away.

This line is leading to the substation in northern Hebei, and it stopped inexplicably......

Stop is not can not stop, if it is a line maintenance or something, the scheduling is arranged, you can stop, the opposite side can be operated first, but at the moment the scheduling did not give any notice or arrangement, and the Hebei substation has just been overhauled a few years ago, it is impossible to be so frequent.

Isn't there a problem with your own factory?

Oh my God......

365 days a year when is it not possible, why is it now!!

According to the regulations, this situation should be reported to the dispatch as soon as possible, and then the equipment should be checked, but if you follow the regulations, this simple practical assessment can become complicated...... What if something really happens in the factory......

No one dares to be this sinner.

Like Ye Qingqing, the young attendant also subconsciously looked back at the leaders.

This hope is not good, it just happened to collide with Qin Yong.

"Oh, what's going on?" Qin Yong raised his eyebrows and asked, "Did the dispatch order come from there?"

When asked by the chief of the department, the young attendant immediately panicked and couldn't say a word.

Rao is Ye Qingqing took a deep breath and turned around and said, "Still waiting for further instructions from the dispatcher." ”

"Take the initiative. Qin Yong didn't show anything unusual, and waved his big arm and said, "This is an assessment of you, not a test of scheduling, seek truth from facts, and strive for efficiency." ”

After that, he turned his head to look at Zhao Wenyuan: "Director Zhao, we have also seen the rigor of North China scheduling, is it not a violation to urge like this?"

"No, it doesn't count. Zhao Wenyuan nodded and smiled, and also said to Ye Qingqing, "Let's get in touch, Director Qin has spoken, and if there is no problem, quickly disconnect the line from bus I." ”

"Okay. Ye Qingqing held her breath and responded, and then ordered the attendant next to her to sit in her place to contact the dispatcher, and she herself got up and glanced at Zhang Yifu.

Zhang Yifu kept staring over there, although he didn't see the change in the dashboard, but judging from Ye Qingqing's eyes, he was afraid that something was wrong.

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

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

At this time, her face was already pale.

"Shaw...... The fifth line stopped ......"

"No. 5?" Zhang Yifu swallowed and spit, and his brain was also blank, "Line 2911 is going to the northern Hebei substation?"

Ye Qingqing nodded solemnly: "I didn't dare to say it...... We...... How to deal with it?"

Zhang Yifu gasped, afraid of something, why did he get into such trouble at the last moment of reaching the standard. You must know that a power plant that has had an accident within a year cannot apply for compliance with the standard, and even if it is a standard power plant, if there is a certain accident, it will also face the punishment of delisting, just like Fengzhou.

Of course, Fengzhou has no right to choose, it is so unreasonable, something happens is an accident, and it is a major event that the whole network has seen.

However, the current northern Hebei and the current Zhang Yifu are facing a terrible choice question.

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

Even if the leaders are very tolerant, if this kind of thing happens in practice, as long as the matter is related to the power plant, I am afraid that it will be over.

So what if you don't report it? The bureau dispatch may soon be able to show itself.

The line is disconnected, and the power supply line of the Hebei substation is missing.

The role of the substation is similar to that of a large transformer, the role is to change the voltage, long-distance power transmission requires high-voltage electricity, the power supply in the network needs to use high-voltage electricity, and the voltage requirements for local power supply are lower. The substation is to change the electricity obtained from the power grid and power plant into these different orders of magnitude of power energy.

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

The first is a checkpoint and a hub of the power grid in the northern part of Hebei Province.

The second is to allocate local loads for production and living power supply.

Third, and the most important in the political sense, the power of the power grid in the northern Hebei region will be boosted and transmitted to Jijing through the guò high-voltage transmission line to supply the power demand of the capital.

Ensuring all power supply is almost always the top priority of the North China Power Grid and the North China Bureau.

As a direct connection to the North Hebei Power Plant, the North Hebei Substation undoubtedly plays a pivotal role in this task.

Now the line is broken......

Although there are other lines in and out of the Jibei substation, and there are other sources of electric energy, it has entered a precarious state without the Jibei power plant. The load of each line of the substation is limited, the line in northern Hebei is gone, but the power supply and demand are still there, the frequency of the power grid is still like that, for other lines, it is likely that there will be a load situation, maybe there is no obvious sign in a short time, but once the load time is long, the line will be damaged, and the line that was originally suspended in the air will hang down like a noodle......

Ground faults caused by this kind of "ramen" and line tripping and circuit breaking accidents are not uncommon in the industry.

Zhang Yifu didn't dare to think about it anymore. (To be continued!)
