2008 is an intimate and charming combination of numbers, which is deeply imprinted in people's hearts together with the exquisitely shaped Chinese knot. However, just as people enter the New Year and experience the colorful dreams that 2008 is about to bring, the first thing that falls on people's vision is the rain and snow flying in the south.

Lu Zhengdong looked at the white expanse, thinking about the disaster report of the southern provinces and cities, in January, the first snow of 2008 fell in the provincial capital of Beihu, at that time it brought people not panic, on the contrary, it was a rare beauty. Many newcomers took advantage of this rare snow scene to take pictures. No one could have imagined that the snow would be so unsatisfactory in the days to come.

At the same time, water pipes often freeze and burst in some old residential buildings in Shajin, the capital of Zhanggan province, and most of the affected residents do not feel particularly surprised except that their lives are somewhat inconvenient, because such incidents often occur in the harsh winters of previous years. Only a few people noticed that it seemed that the ice under the water pipes was bigger than in previous years. Although something unusual was felt, it was not expected that this would be a precursor to a catastrophe.

At this time, the cold and warm airflows from the northwest, northeast and southwest are approaching most of the southern part of China and the eastern part of the northwest region. In 2008, the first snow fell in most parts of the southern part of the country, which also opened the prelude to a rare low-temperature rain, snow and ice disaster.

The footsteps of the blizzard and the footsteps of hundreds of millions of Chinese returning home for the holiday met unexpectedly. But at that time, the end of the year was approaching, and people felt everywhere not the disaster but the desire to go home. No one could have imagined that it would eventually affect more than 100 million people in 20 provinces (autonomous regions and municipalities) across the country.

Before the first snow had completely melted, a second blizzard struck again. The second cold air pushes from west to east. This is very unusual compared to previous years.

Entering the end of January. A third blizzard followed. The third snowfall was the turning point of this low-temperature rain and snow disaster. For Beihu and Nanju. The severe weather that began in mid-January lasted for a period of time once in a century, with the most severe low-temperature rain and snow weather in five or nine years at Beihu Lake, the continuous freezing rain days in Qianyang breaking through the historical record, and the continuous snowfall in Zhanggan for 24 days, which was the longest since the founding of New China.

Whether it is the Central Meteorological Observatory or the local meteorological stations of various provinces and cities, at first I felt that this was a very ordinary time, and it should be said that it was very in line with the characteristics of the seasonal changes of the weather. Because every winter our country will be affected by cold wave weather, generally cold air activity for five to a week. The temperature rises after the cold air passes, and the snow melts after the snow falls. Such a cycle of intermittent cold air activity process, but this kind of weather is the old meteorology who has participated in the work for decades admit frankly, I have not seen Beihu, Qianyang Province, most of Nanhu, most of Zhanggan, and even to the northwest of Guangdong There is a wide range of freezing rain weather, which is very rare. In the historical records of previous years, and the process I have experienced, there have been three consecutive widespread rain and snow in a month or even 20 days, which is very rare.

And this sudden rain, snow and ice disaster. The time of the rampant time is the eve of the Spring Festival, which is the annual great migration of the whole people, and at the same time, it swept the area in the south, which is accustomed to the warm winter sun.

If such weather occurs in the north. Even minus 40 degrees Celsius is fine, the main reason is that the northern climate is dry and there is no strict icing. However, in the south, due to the rarity of such weather, according to the design standard of the southern transmission line, the icing is the design standard of 10~15 mm, and the design is once in 15 to 30 years. This weather is once in 50 years, the ice cover reaches 30 to 60 millimeters, far exceeding the design standard, and the air humidity in the south is high, there is a large amount of water vapor after encountering low temperatures and freezes, so that the conductors freeze, the iron tower collapses, and the low temperature causes the temperature to be too low to freeze for a long time, so that the disaster continues.

Due to the continuous low temperature, rain and snow weather, the country's newest and most advanced transmission line, which is also the main artery of west-to-east power transmission, and the four line towers were crushed by rain and snow.

In Qianyang Province, there was a freezing disaster with the lowest temperature and the longest duration and the widest range of impact since the meteorological record, more than 2,000 lines were damaged, and the power grid of Qianyang Province was forced to start the emergency plan and stop selling electricity to the outside world, and the province entered a red warning state of large-scale power outage.

And because most of the transmission lines are in mountainous and hilly areas, and the ground is icy and it is difficult to transport maintenance equipment and materials to the site, no one knows when the power will be restored.

And in terms of railways. Since the founding of the People's Republic of China, the unprecedented railway congestion caused by disasters has begun, and more than 100 passenger trains have been delayed on the Beijing-Guangdong line alone, and about 40,000 passengers have been stranded in Beihu.

And in terms of railways. Since the founding of the People's Republic of China, the unprecedented railway congestion caused by disasters has begun, and more than 100 passenger trains have been delayed on the Beijing-Guangdong line alone, and about 40,000 passengers have been stranded in Beihu.

Huacheng, located at the southernmost end of the Beijing-Guangdong Railway, the vast majority of passengers waiting to get on the train are not yet aware of the qiē that has happened on the way home. It wasn't until the next day, in the midst of the growing crowds, that people waiting to go home realized that the railway was broken, but people continued to pour into the station. Dozens of millions of people are waiting to leave for the Chinese New Year......

The snowfall has closed some highways one after another, and many provinces and cities have closed their entire highways.

Even if Beihu took measures at the earliest, it was resolutely not to close the road, and resolutely took diversion measures, but even so, due to the ice and snow disaster, the Chengpu Expressway was only blocked in Beihu at this time, and the traffic dragon was still stretched for dozens of kilometers, with hundreds of thousands of people stranded.

The treacherous climate and environment in the ice and snow have nearly collapsed tens of millions of private car owners and people who are preparing to drive home for the Spring Festival: high-speed car accidents, traffic jams, and vehicle damage...... Many problems are destroying the fragile nerves of car owners, and I am afraid that this situation will have to be celebrated on the road for the New Year, and such anxiety is still spreading......

And this qiē is closely related to Jiao Yun.

Jiaoyun, located in Beihu Province, has been a key point connecting the north and the south since ancient times. The two major arteries connecting the north and south of the country pass through it. At this time, Jiaoyun not only became an isolated island, but also an extremely important geographical location, as well as the most severely affected by the disaster, whether the two major transportation arteries could be opened in Jiaoyun became the most critical link, which directly affected the fate of most of China and millions of people.

So at this time, Jiaoyun became the focus of the whole country......

It is precisely because of this that even if Lu Zhengdong made a decision and deployment, and the whole province made a general mobilization, he did not dare to take it lightly in the slightest......

"Secretary, Secretary General Qiu of the State Council has an emergency call!"

Sitting in the car like a snail, Chen Jiqiao gave the phone to Lu Zhengdong.

"Secretary-General. I am Lu Zhengdong, we have made the latest diversion plan, we must ensure that before the arrival of a new round of disaster weather, the Chengpu Expressway and the restoration of the power of the railway, open up the channel to connect Jiaoyun, please rest assured, we will do our best in the whole province of Beihu! Well? Not asking about this? Is it a matter of electricity supply? The eastern power grid of Qianyang Province cannot be integrated into the main network of Qianyang? Well, okay, okay, I'll get to know the situation right away, and I'll report back as soon as I get the results......"

"There is a situation to inform you that the third heavy snow raid brought a fatal raid to the Qianyang power grid, the eastern power grid of Qianyang completely collapsed, and a power tower collapsed, and below it is the transmission catenary of the Beijing-Guangdong electrified railway. The 100,000-volt high-voltage line is set on the 25,000-volt railway transmission line, and the railway power supply is interrupted instantly, if a part of the power cannot be supplied from the outside for black start, not only the power of the eastern part of Qianyang is not connected to the grid, but the power system of the Beijing-Guangdong Railway cannot be restored in a short time. ”

Lu Zhengdong didn't understand such a professional term, not only that, but also the other people who accompanied him, so Lu Zhengdong immediately asked the chief engineer of the power system who accompanied him.

"The so-called black start refers to the start of the unit with self-starting ability through guò after the whole system is shut down due to failure, and drives the unit without self-starting ability, gradually expands the recovery range of the power system, and finally realizes the recovery of the entire power system."

"Do you think it's technically possible?"

Lu Zhengdong can't make a judgment on this kind of very professional matter, and he can only listen to the opinions of experts in this field.

"It's technically possible."

Chief Engineer He hesitated for a moment and then said:

"But the risk of doing so is very high, and if it fails, there will be a risk that our Beihu power grid system will be damaged, especially since our Beihu power grid is also in the most difficult and dangerous time, and the risk is particularly huge."

Hearing Chief Engineer He's words, the van suddenly fell into silence, everyone knows that once such a start fails, it not only means that Beihu not only has failed to rescue and restore the power system in the previous stage, but also will make matters worse, and the power grid of Beihu Lake itself is full of holes to further deteriorate, and on the other hand, it is the need of the overall situation, if the power in the east of Qianyang cannot be restored to a certain extent, the power recovery in the east of Qianyang will not be able to be realized in the near future. If the main artery of the Beijing-Guangdong railway wants to be restored, it will be even more difficult, and then it will affect most of the provinces and cities affected by the disaster, Lu Zhengdong is very clear, but where there is a trace of other options, the central government and the general manager will not let Beihu, which is in urgent need of rescue, to supply power to Qianyang, which is also a last resort in desperation, on the one hand, Beihu has to meet the realistic needs, on the other hand, the overall needs, it is really a dilemma.

The whole country is a game of chess, the small family obeys everyone, and the local obeys the overall situation, everyone knows this truth, but it is one thing to be clear, if you really have to sacrifice your own part to ensure the overall situation, this is not an easy thing, and for Lu Zhengdong, it is even more tormenting, because he is the number one, and this determination must be made by him.
