Riding the wind of rebirth

Chapter 1871 New Design

Like many companies today, the Blue Sky Sunshine Group's large conference room is arranged as an "achievement showroom", filled with various trophies, awards, photos of leaders' inspections and the like, with a strong "state-owned enterprise reform" style.

In fact, the shareholding structure of this company is quite complex, with the province deeply involved. It is also a model enterprise that the Shudu leaders are very proud of for "successfully reforming and gaining new vitality."

Deng Guangrong first introduced the glorious history and difficult restructuring of the enterprise, and then described how everyone worked hard and created brilliance in the wave of reform and opening up. In the meantime, he also expressed his deep gratitude to the strategic partners for their great help.

After the formal remarks were made, Chief Engineer Lu Hui introduced the wind-solar complementary power generation project. In fact, this project already existed in Blue Sky Sunshine's existing projects, but they were all small projects below 1kw. This 10kw+5kw networking project is the first time for Blue Sky Sunshine.

Although it is still a small-scale operation, this action also has several innovations. The first is to combine independent kW-class wind turbines into a power generation grid to construct a 10kW-class wind turbine cluster power station.

This point should not be underestimated, because small units have many advantages such as easy transportation, maintenance, replacement, and easy adjustment of network scale. The only inconvenience is the addition of networking control modules and land occupation.

However, wind power itself is basically installed in sparsely populated areas, so the latter inconvenience can almost be ignored.

In this way, the power generation level of the power station can be increased to a higher level without redesigning the unit, so it has application advantages.

The only difficulty lies in the design of intelligent monitoring equipment. The system must monitor the operation of each unit and adjust the wind power in order to obtain stable output. Compared with previous household equipment, this forms a generation difference between diesel generators and small power stations.

However, Blue Sky Sunshine Group does have this monitoring device. The solar power station installed in Zhouzhi is equipped with one to monitor the health status of solar panels and batteries.

Lu Hui is very familiar with the various systems of his group. He can talk about various professional terms and technical parameters at will. However, he also mentioned the technical difficulties in converting this set of monitoring equipment from solar energy to wind energy.

Zhou Zhi could fully understand this point. The changes in sunlight are very slow. In a place like Liangshan Prefecture where the sunshine time exceeds 300 days, it can even be said to be relatively stable. This kind of slowly changing monitoring and control puts very little pressure on the system and can even be predicted.

But it is completely different for wind power equipment. It is almost impossible to expect stable wind power during most of the day in a year.

Therefore, the system's sensitivity to such changes will increase dramatically.

This is thanks to the rapid development of information systems. With the industrial control chip integrating the Clover Minicos core instruction set, the system's ability to handle complex situations has also been greatly improved. Now it has fully supported the idea of ​​a networked monitoring system for wind turbines to turn from a blueprint into reality.

This demand actually did not come from the Clover Group, but more from Nordic customers. However, one cannot take on a job without the right tools, so one must first find a project in China to verify the application of the system.

Therefore, the cost of this project is not of great concern to the Blue Sky Sunshine Group. What they need is local support and customers who have a high tolerance for this system.

From the pleasant experience of cooperation with Clover, everyone thinks Zhouzhi is a very cute little white mouse. However, this time, the little white mouse has brought new content to everyone as usual. This system is no longer just a wind-solar complementary power generation project, but also has the part of pumped storage, and at the same time, it also has to combine agricultural water resources issues. It seems... it has become more grand.

"Green Energy Ecological Integrated System, I wonder if you can accept this name." Zhou Zhi said: "Liangshan Prefecture has a three-month dry season, a three-month rainy season, and a half-year windy season. We don't want this power station to just solve one problem, but rather it can solve a series of problems."

"I believe your foreign customers will also be interested in such a system." Zhou Zhi added: "For example, the Netherlands also has similar problems to ours, but it is not about water storage, but drainage. Their low-lying areas are flooded, just like our Lianhe Township, where one is dying of drought and the other is dying of floods, but the pain is the same."

This sentence made everyone laugh.

It was quite easy to discuss the plan. A similar plan had been tried by Blue Sky Sunshine in the pastoral area, namely the wind power adaptive pumping station. According to the characteristics of Lianhe Township, Lu Hui quickly gave a more reasonable plan, which was to design several graded pumping stations between the power station on the top of the mountain and the foot of the mountain.

This can greatly reduce the difficulty of pumping water to the reservoir on the top of the mountain. At the same time, each level of the pumping station can also realize some daily functions of water storage and irrigation.

With the water storage function of these pumping stations, there are basically no serious problems during the three-month dry season in Lianhe Township.

As for the windy season, there is no need to consider it, as wind power alone can meet the water pumping needs.

Of course, there are still many details that need to be introduced and discussed. For example, Lu Hui mentioned a very tricky problem - the wind problem.

It's not that the wind is too weak, but that the wind is too strong.

The problem of low wind speed is actually easy to solve, that is to increase the area where the wind acts. This can be solved by increasing the length of the wind blades, increasing the surface area, adding planetary gear sets, increasing the motor shaft speed, and many other methods.

On the contrary, it is troublesome if the wind is too strong. If the wind is too strong and the speed exceeds the limit, it will damage the fan blades and burn the motor.

The monitoring system played a role again. Lu Hui once again introduced the latest research achievement of the group, which is to design the wind blades to be non-fixed.

When the system detects that the current wind force is too strong, it will control the fan blades to adjust a certain angle, reducing the force area of ​​the pushing angle to achieve the purpose of reducing the rotation speed.

When the wind force decreases, the fan blades will be adjusted back to the appropriate force angle, the force area will increase, and the force size will remain unchanged, so that a more stable work output can be achieved.

This function would have been impossible to achieve with traditional analog circuits in the past. Now with the industrial control chip, Lu Hui and his technical team have added a large number of digital functions, improving the product performance by one and a half generations.

"In the past, we could only increase the number of machines from 100 to 1,000, and from 1,000 to 10,000," Lu Hui said confidently. "After the breakthrough in networking capability, we can increase the number of machines from 1,000 to 10,000, and from 10,000 to 100,000!"
