According to the practical experience of Yili Group, it is necessary to achieve integrated desertification control of "roads, electricity, water, telecommunications and green". That is, where the road is repaired, electricity will be connected, water will be connected, communication will be connected, and greening will radiate to wherever it is.

Mr. Qian Xuesen also put forward a "sand industry theory" that the sand industry should make full use of the favorable conditions such as sunshine and temperature difference in the desert and Gobi, popularize the use of water-saving production technology, and engage in knowledge-intensive modern agriculture.

Knowing the controversy within the expert group, Qi Zheng intended to add more bargaining chips for the large-scale development of the desert.

Whether it is the construction of reservoirs or the development of deserts, it requires a lot of manpower, material and financial resources, and among them, electricity is the most indispensable.

Electricity, either brought in from outside or produced itself from renewable sources.

Qi Zheng chose the latter, but instead of following Mr. Qian's theory, he chose to develop solar energy, but first chose to develop wind energy.

Soon, a group of wind resource engineers came to the desert to carry out wind measurement data analysis, wind farm site selection and capacity assessment.

Academician Yuan also soon found out, and he came over to ask Qi Zheng: "Are you planning to develop wind energy in the desert?"

Qi Zheng simply nodded: "That's right." Whether it is the Tengger Desert or the Badain Jaran Desert, the average annual wind speed is about 4 m/s, and the number of windy days is 30-50 days per year, which is one of the rich areas of wind energy resources in the desert, which provides a premise for the use of wind energy. ”

Academician Yuan nodded at first, but then reminded: "Wind power is not as beautiful as imagined, and investment needs to be cautious!"

Qi Zheng knows this better than anyone else.

If you pay attention to new energy, later generations can often hear a saying "wind curtailment", which is the difficulty of wind power development.

Mongolia Province is the region with the most abundant wind energy resources in China, accounting for more than 30% of the total wind energy resources in the country, with unique wind energy resources, good construction conditions and relatively low development costs.

However, the economy of Mongolia Province is underdeveloped, and the local incremental electricity consumption is limited, and more can only be delivered.

The problem arises, the random and uncontrollable operation of wind power and the strict requirements of the grid are inherently contradictory.

Wind power, this uncle, come when he says, go when he says, sometimes he is short-tempered, sometimes he is gentle as water...... The intermittent and unstable nature of wind power leads to wind power integration into the grid, which can impact the grid and worsen power quality.

The most important factor restricting the development of wind power is the problem of grid access, and an important reason restricting wind power grid is the large fluctuation of wind power.

The construction of wind farms in the northwest is booming, but the end result is that so many windmills stand on the Gobi Desert to bask in the sun, and even if some windmills are spinning, most of them are also idling there. What is the use of the electricity that cannot be transmitted or saved?

Of course, the construction of the wind farm in Jiagu first hopes to ensure that the electricity is used at home, and the problem of electricity grid can be ignored for the time being.

But even if it is home electricity, stability is also very important, when the wind is strong, the fan can rotate at full speed, and the power supply can be guaranteed, but when the wind is small, or there is no wind, it will be troublesome!

And how to ensure the stability of wind farm power generation as much as possible, in addition to relying on God, it also depends on site selection.

Engineer Luo is the leader of the wind resource survey and wind farm design team hired by Jiagu. Whether it is from the popularity of Jiagu or from the development plan of the desert, one conclusion can be drawn that this is a local tyrant who is not easy to mess with.

In the face of this kind of local tyrant, it is best to be honest.

Therefore, Engineer Luo first said ugly words: "Mr. Qi, you should know that the wind has always been in a state of change in nature, and its characteristics are not the same in different years, and the wind energy in a region is also very different from that in a windy year. Therefore, it is difficult to say that the trend characteristics of assessing the wind resource potential of a place without long-term statistics as a reference are completely correct. We can only provide the design of the wind farm according to the existing wind measurement data!"

Qi Zheng nodded in understanding, wind resources are the same as weather forecasts, and there will always be internal contradictions among the people who want 100% accurate forecasts and "concubines can't do it". Even with long-term statistics as a reference, there are many difficulties in the industry.

Engineer Luo saw Qi Zheng's understanding, and only then did he show a smile.

Probably seeing that Qi Zheng was not difficult to get along with, while waiting for the preliminary data, he took the initiative to popularize some common sense of wind power to Qi Zheng: "The international average wind speed is 6, 7, and 8m/s, which are average, better, and best wind farms. Among the thousands of stations in China, there are only a few dozen with an average annual wind speed of more than 6m/s, and there are few left except for the high mountain station, and the problem of site selection is still very prominent. To be honest, this is the first time I have come into contact with desert wind farms, and I hope to find a better site for wind farms. ”

"The quality of wind resources directly affects the amount of wind power generated, which in turn affects the cost of power generation. You know, wind energy is to the 3rd power of wind speed. That is, the difference in wind speed is 1 times, and the difference in wind energy is 8 times. Therefore, it is crucial to choose a good wind farm wind speed. ”

"Since the stability of wind speed needs to be taken into account in the utilization of wind energy, it is necessary not to have excessive diurnal and seasonal variations in wind speed when selecting a site. In addition, for wind turbines, in addition to better wind resource conditions, it is always hoped that there will be a relatively stable wind direction......"

Engineer Luo finally said: "Judging from the case analysis of a large number of wind farms in operation, it is basically impossible to have a perfect wind farm, and most wind farms always have some units that are inefficient assets or operate in sub-healthy conditions......

Before he could finish speaking, his subordinates sent him a stack of materials.

He was a little surprised: "There is a goal so soon?"

When I opened the information, I said, "Uh...... Huh?"

Qi Zheng asked, "What's wrong?"

Engineer Luo said with a somewhat complicated face: "Uh...... I think I've found a wind farm with good wind resources?"

"That's really good! You guys can be efficient!"

Isn't it good? The current data is simply perfect!Engineer Luo roared in his heart.

The average wind speed of 8 m/s is the standard for the best wind farms, the seasonal variation of wind speed is difficult to say, but the diurnal variation is very small, and the wind direction is extremely stable...... Special meow, could it be more perfect?

Although he was slapped in the face, his joy was even more obvious, after all, it was impossible to meet the best wind farm. Of course, more data is needed to determine the specifics of wind resources, but at least there is a target, isn't it?

At this time, Qi Zheng asked: "By the way, where is that wind farm?"

Engineer Luo did not doubt him, and pointed in the direction of the foothills: "It's in the foothills over there." ”

Qi Zheng slightly hooked the corners of his mouth.

"Tiangang Wuji Array triggered, the main gold and water systems, range: 250 kilometers around. Effect: Extreme pressure, wind. It can control the air pressure, and the wind and water rise. ”

There is no "perfect" wind farm, only "man-made" wind farm.

In order to fight against the spirit array of wind and sand, Qi Zheng changed his thinking and was used to "control the wind".

In this way, not only can a stable wind field be formed in a certain area, but even better, the spirit array is more labor-saving energy will not disappear out of thin air, rather than fighting against the wind and sand, it is better to fine-tune it into a stable wind, which will not form a large wind and sand, and can stably develop new energy.

With a stable wind farm, wind power is definitely the cleanest energy source, and the pollution generated in the process of manufacturing windmills is also minimal, and compared to solar power generation, a large number of highly toxic substances will be produced in the process of solar panel production.

The "windmills" stand like a forest, and the blades rotate slowly, but they are actually very beautiful, isn't it?

The clever use of the natural resource endowment of the desert and the full realization of ecological development not only add bargaining chips to the desert development of Jiagu, but also Qi Zheng hopes to set a tone for the utilization of natural resources in the desert: economical utilization!

If the management is not in place, the awareness of water conservation is not strengthened, and no matter how much water resources he tries to transfer back to China, it will not be wasteful.
