On the other side.

The boss of Dongtang Power Grid, who was originally scheduled to come for inspection on January 3, changed the time to January 10 due to emergencies.

Thunder Group had no objection, because their president Fang Shengjie was at Mi Li's house at this time.

Huang Haojie can only personally entertain the boss of Dongtang Power Grid.

Huang Haojie led the boss of Dongtang Power Grid Du Lidao to the stone bay of Lucheng, Shanmei. Here is the first wind power station just built by Haifeng Wind Power Company.

Fifty huge vertical wind turbines are operating rapidly at this time.

These large wind turbines with power generation power up to 1,500 kilowatt-hours can generate 50,000 to 60,000 kilowatt-hours in one hour.

Du Lidao looked at the wind turbine running at high speed and asked the wind power expert who was following him:

"Mr. Zhang, how efficient are these wind powers?"

Perhaps because of his frequent outdoor work, Zhang Gong's skin was rough and dark. He said very excitedly and excitedly:

"Mr. Du, it's really amazing. I just calculated that their fan's comprehensive efficiency has reached 48-50, which is a miracle."

After listening to Zhang Gong's explanation, Du Lidao, as the boss of Dongtang Power Grid, was still clear about these power generation channels.

He knows that the most powerful vertical wind turbine on the market has a comprehensive efficiency of around 20, while the horizontal wind turbine is theoretically around 50, and in fact around 30.

However, considering the cost of horizontal wind turbines, the vertical wind turbine won another game. The kilowatt kilowatt cost of horizontal wind turbine door is about 3,000 to 4,000 Chinese Yuan; the vertical wind turbine costs about 2,000 Chinese Yuan per kilowatt.

After a while of thinking, Du Lidao asked Huang Haojie on the side:

"Mr. Huang, what is your fan cost or selling price?"

Perhaps considering that the cost is not appropriate, Du Lidao changed to the price to ask.

"Each kilowatt is 5,000 Huayuan, a large fan with a power of 1,500 kilowatt-hours is priced at 7.5 million Huayuan. A fan can generate about 10 million kilowatt-hours of electricity a year, and you can make a return within about three years." Fang Ping, who was standing by, quickly replied.

After listening to Fang Ping's explanation, Zhang Gong from Dongtang Power Grid asked back:

"Three years to make a profit? Is it in a rich area?"

Fang Ping quickly shook his head and explained:

"No, it's in a rich area. If it's in a rich area, it may take less than three years. If it's in a usable area, it's about four or five years! This data is calculated based on Shanmei Stone Bay. After all, the wind energy here is probably between rich and available."

"If you say so, your starting wind speed should be very low." Experts are experts, so Zhang Gong immediately asked the key points.

Fang Ping nodded: "That's right, our Haifeng Type 2 wind turbine has a starting wind speed of 1.2 meters per second."

Du Lidao, who was standing by, calculated that if a wind turbine with a power of 1,500 kilowatt-hours can really be able to achieve 10 million kilowatt-hours of wind power a year, there is really a lot of potential.

"Mr. Huang! Can you check your generator system?"

Huang Haojie nodded: "Yes!"

"Mr. Zhang, take a few people to see!"

Hearing Du Liguo's words, Zhang Gong was immediately excited. After all, for a wind power expert, he could personally contact this cross-age product, just like a foodie encountered a rare food.

He hurriedly took a large number of instruments and four or five national power grid staff toward the nearest wind turbine.

In order to avoid them not understanding the wind turbine, Zhang Haifeng and other engineers from Haifeng Wind Power also followed.

Zhang Gongzai carefully tested various data of the wind turbine, the surface area, volume and weight of the on-site wind speed blades, the output power of the generator, etc.

After more than an hour of testing, we finally got a data similar to Haifeng Wind Power.

After handing the report to Du Lidao, he kept muttering words like "It turned out to be true, I really can't believe it". Obviously, he was shocked by the performance of the Haifeng Type 2 wind turbine.

Du Lidao looked at the report in his hand and couldn't help but squint. A 1,500 kilowatt-hour fan had a total cost of 7.5 million huayuan. With the supporting facilities, the total cost is about 9 million huayuan. Based on the current wind power on-grid price of 0.3 huayuan per kilowatt-hour, it can really make a return in about three years.

But he is more interested in the Thor modified battery.

"Mr. Huang, your wind power technology is beyond doubt."

After saying that, Du Lidao gave a thumbs up and continued:

"Mr. Huang, let's go and see your power storage station!"

"No problem! Please come with me!"

Huang Haojie led Du Lidao and his group into the power storage station of the No. 1 Power Station in Shishi Bay.

Rows of twenty-meter-high reinforced concrete bungalows appeared in front of everyone.

"Mr. Du, this is the power storage area of ​​the No. 1 Power Station. Each power storage bin has a Thor modified battery of 1,000 tons, and there are a total of 30 power storage bins. Of course, due to the production of Thor modified battery, we only have three power storage bins for the time being."

Huang Haojie introduced while walking.

"How much electricity can a power storage tank or a Thor modified battery of 1,000 tons?" Du Lidao asked hurriedly.

"A power storage warehousing can store 240,000 kilowatt-hours of electricity. Of course, the power storage warehousing is just for the convenience of dispatching. Only a part of the power generation of the power station is stored here."

Du Lidao nodded. Of course he knew that the function of the power storage station was not to store electricity, but to regulate the time and space unevenness of the electrical energy.

Last year (2016), Dongtang's annual power generation was 6.14 trillion kWh, with an average daily power generation of 17 billion kWh.

You only need to build a power storage station with a power storage capacity of about 5 billion kilowatt-hours.

In this way, during the power consumption trough period, excess electricity can be stored in the power storage station. When the power consumption peak period, power can be drawn out from the power storage station.

Does this seem like a waste of time?

In fact, doing so can save a lot of electricity and reduce the capacity of very large power generation.

Dongtang generates 17 billion kilowatt-hours of power per day, which means that it requires up to 800 million kilowatts of power installed capacity.

In fact, the national installed power generation capacity of Dongtang in 2016 was 1.5 billion kilowatts.

Why this situation occurs mainly because there are more than 300 million kilowatts of wind power and photovoltaic power. These unstable power supplies must be equipped with thermal power stations with similar capacity to adjust.

Otherwise, judging from the power generation situation of wind power and photoelectricity, sometimes non-existent, sometimes large and sometimes small, one-third of the country's electricity consumption will be seriously affected.

It is precisely the instability of these wind power and photovoltaics that have led to the utilization rate of only about half of the country's utilization capacity despite a total installed capacity of 1.5 billion kilowatts.

If power storage stations are promoted, the domestic installed power generation capacity can be reduced to about 1 billion kilowatts, which can meet the normal needs of the country.

After more than three hours of visit.

Du Lidao, who was still unsatisfied, began to calculate that if he wanted to build a 5 billion kilowatt-hour power storage station, at least 20 million tons of Thor modified batteries were needed.

The price of Thor's modified battery is 50,000 Huayuan per ton, which means that it requires a total of about 1 trillion Huayuan. With other supporting facilities, the total cost is no less than 1.5 trillion Huayuan.

Of course, Huang Haojie has promised that if they place a large order, the price can be given to them 40,000 Huayuan per ton in one year, and the price can be reduced to 30,000 per ton in three years.

Of course, such a huge order cannot be decided by Du Lidao alone, and Dongtang Power Grid is not a private enterprise.
Chapter completed!
