"Okay. The attendant was afraid that Zhang Yifu would not let the report be forced by the strong pressure, and the boss spoke, and finally reassured him and quickly picked up the phone.

"Let's go and see. Zhang Yifu immediately patted Chang Jiang, "Others are troubleshooting problems in workstations and power supplies, and they are investigating item by item." ”

After everyone received the order, Chang Jiang followed Zhang Yifu to the vicinity of the booster station.

The booster station is a huge playground, on which many tall equipment are neatly stacked, all of which are high-power transformers, large-capacity switches, and overhead buses, which are used to adjust the output of generators, transmit appropriate electrical energy to the bus, and integrate them into the power grid.

A long time ago, the incident in Fengzhou was the explosion of the booster station switch, which triggered a short-term oscillation of the North China power grid. At that time, Zhang Yifu also participated in the investigation of the accident, the accident had a great internal impact, Miao Delin fell directly, Fengzhou reached the standard and delisted, not to mention, and then introduced a series of safety measures to stabilize the power grid, improve the standard of relay protection, the only thing to be thankful for is that only one switch was blown up at that time, and two other switches were affected, and there were no casualties and major property losses.

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

"What's wrong, Mr. Zhang?"

"Our installation is in ......"

"There's in the electrical room over there. Chang Jiang pointed to the small room on the edge of the substation.

"Let's go. Zhang Yifu is reassured, he really doesn't want to approach switches, transformers or anything now.

The electrical room is the most intuitive and closest to the E1 ground floor equipment, which is filled with various cabinets, not only the microcomputer of the automation system, but also the microcomputer protection, security control devices, etc. Chang Jiang skillfully found the local workstation, and after a series of operations, his face was puzzled: "No problem...... Everything works fine. It seems to be okay here......"

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

Chang Jiang couldn't turn around, so he picked up the walkie-talkie and called the comrades on duty again: "We have no problem here, everything is normal, have you recovered there?"

The man over there quickly replied: "Not at all." The data is still not normal. ”

"That means ......"

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

There is no problem with the equipment of the booster station, and the underlying workstation system is not disturbed, only the data of the booster station of the duty room workstation has a problem, so it seems that there is only a problem with the communication line from the booster station to the central system.

Zhang Yifu grabbed the walkie-talkie and said, "Has the leader of the power plant arrived?"

"Mr. Jia came in person. ”

"Okay, you apply, the booster station here to collect data is interrupted for half a minute, switch to the backup communication line. ”

"Okay, wait a minute............ Mr. Jia agreed. ”

"Wait until I go back with Chang Jiang to start the process. ”

The two hurried back to the duty room, where Jia Luansong was already waiting. There was some nervousness, but not enough to show it.

"Is there a problem on the scene?" Jia Luansong asked, grabbing Zhang Yifu.

"No problem, the booster station equipment and the electrical room are all right. ”

"That's good. Jia Luan breathed a sigh of relief, as long as there were no problems with the primary and secondary equipment. For power workers, transformers, switches, busbars, reactors, etc. are generally referred to as primary equipment, and protection, automation, and security control devices are referred to as secondary equipment.

Jia Luansong thought for a while and asked, "Won't switching that part of the communication line affect production and equipment?"

"No, it won't. "We are in a lot of places. A separate backup communication channel was buried, and a separate channel was taken. It's just that the specifications are not so high, and they are purely spare. For this reason, there is no shortage of rift when planning the wiring. ”

"It's good to be sure there are no security issues. Jia Luansong asked again.

"Absolutely not. "It interrupts data acquisition for about 3 milliseconds." ”

"Let's get started. ”

Not far away, at the automation engineering station, an engineer began to skillfully operate the underlying system, manually and individually changing the communication lines of the booster station. Chang Jiang also stood behind to monitor to avoid misoperation.

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

"It's not up to date yet. Chang Jiang explained, "It will automatically switch when the signal is missing, and now it's just data disorder." ”

"Hmm. ”

That's just two sentences. After the switch, several people returned to the workstation.

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

"Sure enough, it was a communication problem. Jia Luansong smiled at Zhang Yifu, "I'll just say, E1 will not be a problem, when debugging, the most stable is E1, will the problem be on the bus." ”

Although the E1 system has returned to normal, the problem is still unclear, and the hidden danger of unknown reasons is a taboo in safety production.

"Call the people from Siemens first. Zhang Yifu rushed to Changjiang Road.

Chang Jiang was just about to turn his head when the Siemens engineer was already out of breath, a young Chinese.

Zhang Yifu turned his head away, looking too young and a little distrustful.

The young man hurriedly said in broken Mandarin: "I am of Chinese descent and was born in Germany. ”

"Nothing else, just that you're too young. Zhang Yifu smiled awkwardly.

"Let's start with the problem. The young man didn't care, and came to the workstation.

Several people got together, and after a brief exchange, Siemens engineers shook their heads vigorously: "Impossible, absolutely impossible, these communication cables are provided by us, there is no problem, how long is it, our cables can guarantee no problems for 30 years." I'll go check the network equipment first, but I'm sure there won't be a problem either. ”

The young man was full of confidence, but he was still pulled by Hengdian's people to check.

"Could it be a problem in the cable trench?" Zhang Yifu didn't think Siemens would drop the chain, and asked instead.

"If there is a problem in the cable trench, then the data will be directly lost, how can this be so strange? The problem must be on the network equipment. Changjiang apparently believes that the problem is still with Siemens, the installation and laying of the cable trench has been completed, and the power plant has been accepted. E1 is his child, and Beimo is Jia Luansong's child, both of them are good children, they must be.

"Check it out. Zhang Yifu threw an inquiring expression at Jia Luansong.

"Checking the cable trench, it's a hassle. Jia Luansong pondered, "Because not only your communication cables, but also the power cables and control cables of the power plant are also there. ”

The cable is divided into strong and weak current, the socket line is strong current, the telephone line is weak current, weak current is easy to check, and strong current needs to be careful.

The same is true for power plants, communication lines are not dangerous to people, and the power lines that go to the plant are terrible things, after all, to maintain the operation of the power plant, usually after the annual inspection will open the cable trench cover plate and turn around.

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

"Check it out. Zhang Yifu said again.

"Now?" Jia Luansong was still unwilling, but in the face of Zhang Yifu, he couldn't directly refuse.

"Now. Zhang Yifu said, "I have seen many problems, but I can't explain the problem just now, if the microcomputer, communication, and network equipment are normal...... I can't figure out what went wrong and I have to go to the scene. ”

"It's not you who want to go, there are specialized workers. Jia Luansong finally couldn't refuse, and ordered the attendant, "Notify the maintenance personnel, make safety preparations, and go to the main cable trench of the booster station to check, and I will also go over with Mr. Zhang, and wait for us to order to open the cover again." ”

The attendant responded, and Zhang Yifu and others also hurried to the booster station.

They arrived first, but the people who overhauled them hadn't come yet, so Jia Luansong said to the two: "This incident has no consequences, and it has no impact, I will tell the people on duty, don't record it." ”

Zhang Yifu and Chang Jiang both showed embarrassed expressions, and Jia Luansong did a favor and helped E1 hide a small problem. But Chang Jiang was very aggrieved, he was sure that this was not E1's problem, it was that Siemens was unreliable, and there was a problem with Siemens.

All in all, fortunately, it didn't make a big difference.

Not long after, two maintenance personnel arrived at the scene, put on protective clothing in front of the cover, and opened the cover with equipment.

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

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

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

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

"Yes, not dangerously. ”

"Put on your face covering. ”

"Hmm. ”

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

"Will there be any local insulation damage, local short circuit......" Zhang Yifu leaned over and sniffed again, although he didn't see the smoke, but the smell was like the rubber was burned, thick.

Jia Luansong didn't answer, and the khan was already dripping.

This time, he was really scared.

While waiting, Siemens engineers also came to me.

"There is no problem with communication, there is no problem with the interface, no problem at all, but there is a problem with the data!" Siemens engineer pulled Chang Jiang and said, "There is a problem with the electricity coming from the data cable, it is unstable, is there a leakage somewhere?"

This idea coincides with Zhang Yifu.

Jia Luansong still didn't speak, but stared at the cover mouth more nervously.

Another minute later, two maintenance workers came up one after another, took off their masks for the first time, and coughed vigorously.

"Power Cable...... Something went wrong......"

"I didn't see the fire, but the smoke was so thick that I couldn't stay long......"

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

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

The embankment of a thousand miles was destroyed in an anthill!

Chang Jiang and Siemens engineers were even more at a loss.

The two maintenance workers were equally at a loss.

"Mr. Jia, let's ......" The maintenance worker looked at Jia Luansong.

"I'll ...... again Think about it......" Jia Luansong gritted his teeth, his heart was numb.

Now it seems that it has not yet reached the level of fire, but the insulation that wraps the wires has gone wrong, and the insulation may have been broken.

"Is it possible to dig deeper and fix it? Jia Luansong was nervous and asked a very unprofessional sentence. (To be continued.) )
