"Okay." The duty officer was afraid that Zhang Yifu would not allow him to report because he was afraid that the boss would not let him report. He finally reassured him and quickly picked up the phone.

"Let's go to the scene to see it." Zhang Yifu immediately patted Chang Jiang, "Others checked problems in workstations and power supplies, and investigated them one by one."

After everyone received the order, Chang Jiang followed Zhang Yifu to the near the boost station.

The boost station is a huge playground, with many tall equipment neatly coded on it, all of which are high-power transformers, large-capacity switches, and overhead buses, which are used to adjust the output of the generator, transmit appropriate parameters to the busbar, and incorporate them into the power grid.

A long time ago, the incident in Fengzhou was the explosion of the switch at the boost station, which caused a short-term oscillation of the North China Power Grid. At that time, Zhang Yifu also participated in the accident investigation. The internal impact of the accident was great. Miao Delin fell directly and Fengzhou was delisted. A series of safety measures were introduced to stabilize the power grid and improve the standards for retention. The only thing to be thankful was that only one switch was blown up at that time, and two other switches were affected, and there were no personal casualties or major property losses.

Zhang Yifu stood at the entrance of the boost station, remembering the explosion of Fengzhou equipment and the broken porcelain pieces all over the ground, and hesitated for a moment.

"What's wrong with Mr. Zhang?"

“Our installation is…”

"In the electrical room over there." Chang Jiang pointed to the small room on the edge of the substation.

"Let's go." Zhang Yifu felt relieved. He really didn't want to get close to switches, transformers, etc. now.

The electrical room is the most intuitive and closest to the e1 base equipment. It is filled with various cabinets. Not only the microcomputers of the automation system, but also the microcomputer protection, security control devices, etc. are all here. Chang Jiang skillfully found the local workstation, and after a series of operations, he looked puzzled: "No problem... Everything is normal. It seems that there is no problem here..."

Zhang Yifu also looked at the most direct data parameters above. It was indeed no problem and very stable.

Chang Jiang couldn't turn around and picked up the walkie-talkie and called the comrade in the duty room: "We have no problem here, everything is normal, are you recovering there?"

The person there quickly replied: "There is no recovery at all. The data is still abnormal."

“That means…”

Chang Jiang and Zhang Yifu said at the same time: "Communication line."

The boost station equipment is fine, and the underlying workstation system is not disturbed. Only the data on the boost station on the duty room workstation is problematic. In this way, it seems that there is only a problem with the communication line between the boost station and the central system.

Zhang Yifu snatched the intercom and said, "Have the power plant leader arrived?"

"Mr. Jia is here in person."

"Okay, you can apply. The data collection at the boost station is interrupted for half a minute and switch to the backup communication line."

"Okay, wait a moment... Mr. Jia agreed."

"When I go back and I start the process."

The two rushed back to the duty room again, and Jia Luansong was already waiting here. He was a little nervous, but he didn't show it yet.

"Is there any problem at the scene?" Jia Luansong asked, grabbing Zhang Yifu.

"No problem, the boost station equipment and electrical room are fine."

"That's good." Jia Luansong breathed a sigh of relief, and it would be fine if there were no problems with the first and second equipment. For power workers, transformers, switches, busbars, reactors, etc. are generally called primary equipment, and protection, automation, security control devices, etc. are called secondary equipment.

Jia Luansong thought for a while and asked again: "Will switching to that part of the communication line affect production and equipment?"

"No." Zhang Yifu explained, "We have buried separate backup communication channels in many places and walked into other channels. However, the specifications are not that high and are purely backup. For this reason, there are a lot of disputes when planning wiring."

"Just make sure there is no security problem." Jia Luansong asked again.

"Absolutely not." Chang Jiang replied, "It will interrupt data collection for about 3 milliseconds."

"Let's start."

Not far away, an engineer began to operate the underlying system skillfully and manually change the communication line of the boost station separately at the automation engineering station. Chang Jiang also stood behind to monitor to avoid misoperation.

Jia Luansong asked, "Since it is a backup line, why is there no automatic switching?"

"The conditions have not been met yet." Chang Jiang explained, "It is necessary to judge that the signal is missing before it can automatically switch. Now it is just a mess of data."

"Um."

After just a few words, the switch was completed, and the few people returned to the workstation.

After seeing the data as calm as the lake, several people breathed a sigh of relief at the same time.

"It's indeed a communication problem." Jia Luansong smiled at Zhang Yifu, "I just said that there will be no problem with e1. When debugging, the most stable thing is e1. Will the problem lie on the bus."

Although the e1 system has returned to normal, the problem is still unclear. The hidden danger of unknown causes is a taboo in production safety.

"Call Siemens' people first." Zhang Yifu rushed to Changjiang.

Chang Jiang was about to turn his head, but the engineer at Siemens was already panting. He was a young Chinese.

Zhang Yifu turned his head and looked too young and a little distrustful.

The young man quickly said in broken Mandarin: "I am Chinese and born in Germany."

"It's nothing else, it's just that you're too young." Zhang Yifu smiled awkwardly.

"Let's talk about the problem first." The young man didn't care and came to the workstation.

A few people got together and after a simple exchange, the Siemens engineer kept shaking his head: "Impossible, absolutely impossible. These communication cables are provided by us. There is no problem. How long will it take for our cables to ensure that there will be no problems for 30 years. I will check the network equipment first, but I am sure there will be no problems."

The young man was full of confidence, but he was still pulled by the Changdian people to check.

"It may be a problem in the cable trench?" Zhang Yifu didn't think Siemens would lose the chain, so he asked instead.

"If there is a problem in the cable trench, the data will be lost directly. Why is this so strange? The problem must be on the network equipment." Chang Jiang obviously believes that the problem is still in Siemens, the cable trench installation and laying is completed, and the power plant has also been accepted. e1 is his child, and Beimo is Jia Luansong's child. These two are good children, and they must be.

"Check it out." Zhang Yifu threw a questioning expression at Jia Luansong.

"It's very troublesome to check the cable trench." Jia Luansong said, "because not only your communication cables, but also the power cables and control cables of the power plant are there."

The cables are divided into strong electric and weak electric power, the socket cable is strong electric power, and the telephone cable is weak electric power, which is convenient for inspection, and you need to be careful when strong electric power.

The same is true for power plants. Communication lines are not dangerous to people, while power lines that use power plants are terrible. After all, the operation of the power plants is to be maintained. Usually, the cable trench cover will be opened and the cable trench cover will be turned around during the annual inspection.

At this time, it is very troublesome to open the cover plate during the production stage to inspect the cables.

"Check it out." Zhang Yifu said again.

"Now?" Jia Luansong was still unwilling, but he could not directly deny it when facing Zhang Yifu.

"Now." Zhang Yifu said seriously, "I have seen many problems, but the problem just now, if the microcomputer, communication, and network equipment are normal, I can't explain... I can't think of something wrong, I have to go to the scene."

"It's not that you want to go, there are special workers." Jia Luansong finally couldn't refuse and ordered the duty officer, "Notify the maintenance personnel to make safety preparations and go to the main cable trench of the booster station to check. Mr. Zhang and I will also go there and wait until we order to open the cover."

The duty officer responded, and Zhang Yifu and others rushed to the boost station.

They arrived first, and before the maintenance worker arrived, Jia Luansong said to the two of them: "This matter has no consequences and no impact. I will tell the person on duty that I will not record it."

Both Zhang Yifu and Chang Jiang showed embarrassing expressions. Jia Luansong helped and helped e1 hide a small problem. But Chang Jiang was very frustrated. He was sure that this was not a problem with e1, but Siemens was unreliable, and there was something wrong with Siemens.

Anyway, fortunately it didn't have much impact.

Soon, two maintenance personnel arrived at the scene and put on protective clothing in front of the cover, and opened the cover with the equipment.

As soon as the cover was opened, a strong smell of burnt came up, causing several people to cough.

"Is this normal?" Jia Luansongchong asked the maintenance staff.

"It's a bit heavy..." Everyone was also a little panicked.

"Can you still get down?" Jia Luansong asked again.

"Yes, it's not as dangerous as it is."

"Wear a mask."

"Um."

The three of them who had already become down-to-earth, became nervous again.

"Will there be any local insulation damage or partial short circuit..." Zhang Yifu leaned over and smelled it again. Although he didn't see the smoke, the smell seemed to be burnt with rubber, thick.

Jia Luansong didn't answer, and Khan had already dripped.

This time, he was really scared.

After waiting, Siemens engineers also came over.

"There is no problem with communication, no problem with the interface, no problem with the entire data, but there is a problem with the data!" Siemens engineer pulled Chang Jiang and said, "There is a problem with the power coming from the data cable and it is unstable. Is there some leakage? "

This idea coincides with Zhang Yifu.

Jia Luansong still didn't say anything, but stared at the cover even more nervously.

Another minute later, two maintenance workers came up one after another, took off their masks as soon as possible, and kept coughing.

"There's something wrong with the power cable......"

"I didn't see the fire, but the smoke was very thick and I couldn't stay for too long..."

Jia Luansong trembled for a moment when he heard this, and then looked at Zhang Yifu blankly.

Zhang Yifu also gasped and an old saying flashed through his mind.

A thousand-mile dike was destroyed in an ant hole!

Chang Jiang and Siemens engineers were even more confused.

The two maintenance workers were also confused.

"Mr. Jia, we..." The maintenance worker looked at Jia Luansong.

"I... think about it again..." Jia Luansong gritted his teeth, his heart suffocated.

It seems that it has not reached the level of a fire, but the insulation that encloses the wire has already had problems, and the insulation may have been damaged.
Chapter completed!
