The three of them, together with the old secretary, came to the eighth floor dispatch center of the building. The various indicator lights of the grid wiring diagram on the simulated screen flashed continuously, and the alarms were concentrated in the western Shanxi area.

The young dispatchers were in a state of turmoil and kept answering calls. The dispatching director also knew that the news had just arrived. Lin Lin was at the center, his black hair was thick, his big hair was combed, and his delicate glasses were worn. This was a rare leader in the department except Qin Yong, but he was sharper than Qin Yong and less kind and soft.

Zhang Yifu paid more attention to him. After all, this place was where Xia Xue had worked. He was also Xia Xue's first leader and had always taken good care of Xia Xue. It was rare that Xia Xue would be generous in leaving people when she wanted to go to Sanxi.

Lin Lizheng saw that the minister and his party came, and hesitated for a while. If he hadn't allowed irrelevant personnel to enter the dispatch room in the past, but now he had no time to say more, so he began to introduce the situation directly: "Minister, 10 minutes ago, the phase A failure of the 500 kV Hugang line in the Jinxi Power Grid was tripped, and the overlap was not successful. Just now, the three phases of the 500 kV small kiln line have been tripped directly but not overlapped. As of now, more than a dozen 220-500 kV lines in the Jinxi Power Grid have tripped, and several of them are power plants, and all three power plants have been shut down. Is it ice flash or something yet, and the North China dispatcher is waiting for us to make a decision."

Although the situation was a bit chaotic, Lin Lizheng's speech was stable and his mind was clear. Huang Zhenghui was a little more open-minded: "What do you think is the right way to deal with it?"

"We have to unravel the line. The 500 kV Hugang Line and Xiaoyao Line are both the main network connection lines between the Jinxi power grid and North China. With the previous tripping lines, there are only two 220 kV lines left between the western power grid and North China, and there is a high possibility of oscillation." Lin Lizheng immediately replied, "The freezing of three feet is not a day's cold, and it is now considered an ice disaster. First, unravel the line to ensure the safety and stability of the large power grid, and then recover after the problem is checked."

"But..." Bagan scratched his head, "Share is in the west of Jin..."

Lin Lizheng said it was relaxed. It was disgusting to Bagan. Last year, it was a mess because of the accident in Fengzhou. It was completely out of order. This time, it was another major accident! This year, it was a waste of time!

"Time is limited." Lin Lizheng said simply, "Everyone has no objection, so he ordered the order to be unsubscribed."

Huang Zhenghui looked at Zhang Yifu: "Do you have any objections?"

Zhang Yifu shook his head: "Baoda Power Grid, Baojing Power."

Huang Zhenghui nodded and handed Lin Lizheng a positive look.

Bagan naturally had no temper, so he could only scold Lao Tiankong to cheat him.

In the following minutes, Lin Lizheng began to constantly guide the dispatcher to order.

Before the de-listing, the Jinxi Power Grid was a part of the North China Power Grid. Everyone is a whole. De-listing means cutting off this connection. The western Jinxi Power Grid will explode as much as possible, and do not interfere with North China.

Of course, the so-called decoupling is not just about pulling a gate. Take the current accident as an example, the balance of the Jinxi power grid was broken, and it was difficult to maintain 50hz, which has been maintained. Just like water flowing to a low point, the electricity will spontaneously re-seek balance. Because the loss of several main power plants, the frequency may be reduced by at least 1hz as the load changes. Don't be smaller than 1hz. This is a very dangerous change. The entire power system is designed to operate according to 50hz. The 1hz change has a devastating risk for many equipment.

Therefore, in order to pull the frequency back to 50hz, a series of "low-frequency load reduction actions" are needed to cut off part of the load to ensure the balance between power generation and electricity use. Only balance can bring the frequency back to 50hz. The intermediate principle can be expressed by a complex set of formulas, but there is actually a particularly rough explanation to do it.

A bowl of water should be flat.

Now the left side is tilted and it is about to overflow. You have to adjust the angle and pull it back.

Lin Lizheng is undoubtedly a master of adjustment. A series of clear instructions have given young dispatchers a clear mind. After the de-scheduling of the Jinxi Power Grid, the low-frequency load reduction cuts down some less important loads, which immediately made the results. The Jinxi Power Grid quickly stabilized at the standard frequency.

For the first time, everyone thinks that the number 50 is so beautiful.

However, this beauty may be only temporary. The Jinxi Power Grid is still in danger, like walking on thin ice, not right, like carrying heavy ice. If the line continues to trip, either the power generation is cut off or the power is cut off, then 50hz will still not be able to be kept.

"It's cut 120m and it's temporarily stable." Lin Li reported back after confirming the data, "Now we have to race against time to check the problems and restore power supply as soon as possible."

"I'll urge you now." Bagan wiped her sweat and went to the dispatching desk to pick up a phone and wanted to use it.

"Don't use this." Lin Lizheng said immediately, "This is for dispatching purposes, use the one on the left."

"Okay, okay..." Bagan went over in a mess.

The accident was temporarily controlled, and Huang Zhenghui asked: "Why is it so serious? Are there no preventive measures?"

"Minister Huang, we have attached great importance to it. We reminded the North China Bureau and the West Jin Dynasty five days ago. They also expressed that they would take some measures. However, the West Jin Dynasty rarely encounters this situation and has no experience. They hope to mobilize comrades from the south to assist and guide. They were still holding a meeting to discuss this matter."

"Okay!" Huang Zhenghui snorted in a deep voice, "No hurry, I still need someone, and I still have a meeting?"

"What you criticize is." Lin Lizheng took the blame generously, "We also lack safety awareness and should not be so delayed."

"It's not your responsibility." Huang Zhenghui waved his hand, really not letting Lin Lizhi take the blame.

Zhang Yifu asked from the side: "How long has it lasted?"

"I didn't understand it very specifically. If I remember correctly, it's been about three weeks since the first snow." Lin Lizheng nodded, "We reminded us in writing in the second week. They also took some measures, but the rain and snow lasted too long, and the Northern Power Grid lacked experience in this area, so it has not been fully implemented."

Zhang Yifu felt cold in his heart.

It's been three weeks of sleet.

This should be once a century in western Jinxi.

Things like icing usually happen in the south, and it is rare in western Shanxi, so there is no time to prepare.

Blooming is the thing that electric power people hate the most, especially the safety and maintenance of the pipes, which is so hated to the core. To put it bluntly, Blooming means that the transmission lines and poles are wrapped in ice, which will cause wires to dance, broken lines, tilts, collapses, and insulator flashover.
