The rise of great powers: starting from military industry

The junction of Yun County and Jingdong County in western Yun Province.

At this time, a grand ceremony was being held, but the first unit of the Manwan Hydropower Station was connected to the grid to generate electricity.

Manwan Hydropower Station is located in the middle reaches of the Canglan River, 1km downstream of the Manwan River mouth at the junction of Yun County and Jingdong County in the west of Yunnan Province. It is 140 kilometers away from Lincang and 200 kilometers away from DL City. This hydropower station is a comprehensive hydropower station with the goals of power generation, irrigation, water diversion and flood control. It uses a concrete gravity dam with a height of 132 meters and a total storage capacity of 920 million cubic meters. The first phase of the project has an installed capacity of 1.25 million kilowatts and a guaranteed output of 384,200 kilowatts. , with an annual power generation of 6.3 billion kilowatt hours. After the Xiaowan Hydropower Station is built upstream, the second phase of the power station will have an installed capacity of 250,000 kilowatts, with a total installed capacity of 1.5 million kilowatts, a guaranteed output of 796,000 kilowatts, and an annual power generation of 7.88 billion kilowatts. .hour.

Now the first unit is connected to the grid for power generation. Two years later, all five units will be put into operation, and the first phase of the project will be completed. By 1987, both phases of the project were completed.

China's development has exceeded everyone's expectations. This year, water and electricity shortages have begun to occur in Sichuan, Sichuan, mountain cities, Guangdong and Zhejiang provinces. Rural areas have begun to experience frequent water and power outages every day to ensure the development of cities.

Panshan Group, Yunnan Province, Guizhou Province, Guizhou Province, and Sichuan and Sichuan joined forces to form the Southwest Power Grid, which is responsible for the power supply and distribution of the entire southwest. At the same time, it develops hydropower resources in the southwest and is responsible for supplying power to Guangdong Province.

The Manwan Hydropower Station is one of the important hydropower stations.

The entire dam site is located in the lower section of an 'S'-shaped sharp bend. The river valley is narrow, with a bottom width of only more than 60 meters. At an elevation of 1,000 meters, it is about 420 meters wide. The mountain on the left bank is thin, facing the river on three sides, and is a uniform slope of about 40°. The right bank has strong mountains and a terrain slope of 20°~35°.

The dam site controls a watershed area of ​​114,500 square kilometers, with a multi-year average flow rate of 1,230 cubic meters/second. The normal water storage level is 994 meters, the dead water level is 982 meters, and the extraordinary flood level is 997.5 meters. The total storage capacity is 920 million cubic meters, and the regulated storage capacity is 258 million cubic meters. rice.

The first phase of the Manwan Hydropower Station is connected to the grid for power generation, which is of great importance to the Southwest Power Grid.

Panshan Group holds 45% of the shares in the Southwest Power Grid formed by the organization, and the other four provinces and the Ministry of Electric Power hold a combined 55%.

In Yun Province, in addition to Manwan Hydropower Station, there are also Dachaoshan Hydropower Station and Lubuge Hydropower Station, which will soon have their first unit connected to the grid for power generation.

Dachaoshan Hydropower Station is not far from Manwan Hydropower Station. It is located in the middle reaches of the Canglan River and 1.5 kilometers downstream of the entrance of the Naguo River tributary. It is the next cascade power station of Manwan Hydropower Station. It is 70 kilometers away from Manwan Hydropower Station and 70 kilometers away from Kunming City. 270 kilometers away, this hydropower station has the sole development goal of power generation. It is a roller compacted concrete overflow gravity dam with a maximum dam height of 115 meters, a total storage capacity of 940 million cubic meters, an installed capacity of 1.35 million kilowatts, and an annual power generation of 5.931 billion kilowatt hours.

Lubuge Hydropower Station is located in Luoping County, Yunnan Province and Xingyi City, Guizhou Province. The main dam of the power station is a rockfill dam, with a maximum dam height of 103.8 meters. It is a diversion-type hydropower station. Its main task is to generate electricity. The installed capacity is 6 million kilowatts, ensuring output. 850,000 kilowatts, the annual power generation can reach 3 billion kilowatt hours.

In addition, there are 22 hydropower stations under construction or planning in Yunnan Province alone.

The entire southwest is rich in water resources, which can be developed and constructed.

In addition to generating electricity, irrigation, water diversion, and flood control, benefiting the southwest region, a large amount of electricity will be transported to Guangdong Province. Liu Tao gave this plan the name "West to East Power Transmission."

No matter how the southwest region develops, the ceiling will always be visible.

But the southwest is not without its advantages. One is that this is the hinterland of China, and military industry and other related national defense security projects are most reliable in the southwest. Furthermore, my country's hydropower resources rank first in the world, and the hydropower generation potential in the western region is huge.

Among them, the southwest has the richest water resources, accounting for 70% of the country's water resources, but there is very little development.

The launch of the ‘West-East Power Transmission’ strategic project not only effectively utilizes these water resources, but also provides opportunities for the development of the western region.

The "West-East Power Transmission" has two lines. The southern line transmits power from Yunnan, Guizhou, Guangxi and other places to South China, and the middle line transmits power from Sichuan, Sichuan and other places to central and east China.

Once the entire "West-East Power Transmission" is completed, the annual power generation of these hydropower stations will reach 1.344 trillion kilowatt hours, which is a very impressive figure. Even if 1 kilowatt hour of electricity sells for 0.25 yuan, then the annual revenue will be 336 billion yuan. receive.

Of course, the total investment is also huge. It is estimated that 450 billion yuan will be invested, and it will take a total of 40 years to build all the hydropower stations.

450 billion yuan is just a current estimate. It will definitely be higher in the future. Maybe the entire plan will cost trillions of yuan when it is completed.

This is only the construction investment of the project, plus land acquisition, demolition and resettlement, this number may double or even quadruple.

Thanks to the large investment made by Panshan Machinery Factory, Yun Province has the best situation in the entire southwest region. So far, there has been no power shortage or water shortage.

Watching the first unit officially connected to the grid to generate electricity, Liu Tao was very excited.

Who would have thought that in just a few years, Yun Province's annual power generation would increase several times, and that Yun Province's power generation would continue to maintain rapid growth in the next few years.

And these are all the butterfly effects caused by him.

Liu Tao has a clear positioning for Panshan Group, based in the southwest, focusing on the whole country, and moving towards the world!

The entire system of Panshan Group is also a large power consumer.

After all, industrial development itself cannot do without electricity.

This is still now. When there are more and more mobile phones, more and more electrical appliances, more and more shopping malls, and more and more factories, the electricity required will explode.

In 1979, the national power generation was 282 billion kWh, which basically met the national electricity needs. But by 2019, the national electricity consumption had reached 7.3 trillion kWh, and it was still not enough. There were still places with power shortages, which means that the power generation increased by 26 times and it was not enough.

It is conceivable how rapidly China's electricity demand has increased.

Liu Tao promoted the "West-to-East Power Transmission" project because he knew how terrifying the growth of China's electricity consumption was, and no matter how much power was generated, it would not be enough in the future.

For this reason, Liu Tao not only developed high-probability hydropower unit technology, but also developed ultra-high voltage transmission technology.

And in addition to hydropower, thermal power stations will naturally be built to use thermal power.

Even when conditions in Laos, Cambodia and Myanmar are suitable, he will promote the construction of hydropower stations and thermal power stations in these places.

After all, power resources are extremely important resources and an important control tool.

Moreover, the excess electricity can also be transmitted to China for the development of China.

After participating in the grid-connected power generation of the first unit of the Manwan Hydropower Station, Liu Tao left Yunnan Province and went to Yangcheng Shipyard.

At this time, Yangcheng Shipyard was in full swing, building the second Type 022 missile boat, Type 022A torpedo boat, minesweeper, Type 054 frigate and the first Type 039 submarine.

The current Yangcheng Shipyard, whether in terms of plant scale or number of employees, can already rank among the top three in the country.

In a few years, when all the docks are built and the personnel are complete, the entire Yangcheng Shipyard will become the largest shipyard in China.

Just now, the scene of the entire Yangcheng Shipyard is impressive, with thousands of people working hard, the sound of machines and people, all filled with the power of industry.
