　　Dear leaders, experts, ladies and gentlemen:

　　good afternoon everyone. I am Shen Qingsheng, Chief Operating Officer of Beijing Honghui International Energy. The name of my report today is "The "Sprinter" of Flywheel Energy Storage in Grid-side Energy Storage Competition". Sprinting means fast, and an important member of the sports meeting must be fast. What is the biggest news for us in the past few days? There are two big things. The first thing is that the Sino-US trade war is heating up, and the Americans are starting to get serious with us. The second thing is that they are sanctioning Huawei and refusing to sell us. High-tech chips and some products or instruments, these two things show that we must innovate independently and hold things with independent intellectual property rights in our hands. What President Xi said is that "the rice bowl is firmly in the hands of the Chinese people themselves" "The flywheel energy storage technology must be in the hands of our own people, the Chinese people. This photo is one of the things we talked about. I am here to ask three questions to discuss with you today and report on some of the work done by Honghui Company.

　　What can we decide about the future of turning? We have mastered a little bit of flywheel energy storage technology, which can turn the world and spin the future. This is what our boss mentioned and I agree very much. They are all experts in the energy storage industry. I don’t even talk about the principles. In the flywheel energy storage industry, what does Honghui Company do? Honghui Company is an enterprise dedicated to the design, production and research and development of flywheels. We It's the one who makes flywheels. The second one is our team that is responsible for the original marketization of military-civilian integration technology. The third one is to invest some capital. In 2017, we started to introduce Tsinghua Tongfang Collaborative Innovation Researcher and China Development Bank to create an important national weapon. Flywheel. Our current operating situation is that Honghui is in Shunyi. Everyone stops when flying. Jiangyin is our Honghui Company went back and forth over large-scale production bases. We started with small ones and then wanted to make big ones. After many choices, we only made three in the end.

　　The first one is in the field of uninterruptible power supply. Based on the market, we have made three. We have made a 250kw/3kwh energy storage flywheel. The second one is for the energy recovery market. We have made a 300kW flywheel. , energy-type, high-power, energy-storage type, we have made a 200kw/50kwh flywheel. I just saw the large flywheel introduced by Mr. Yes, Mr. Xuan said it very well. As an enterprise, as an innovative company, what we do, we probably cover the following areas, we have a place in uninterruptible power supply and we have completed projects. This is the only 10KV flywheel array flywheel energy storage APS we have made in the United States or in the world. It is made according to the power quality requirements required by our Semiconductor Industry Association, so it is a major innovation in our country and very important. Fortunately, today we are in our cooperative unit. We jointly applied for nomination in the application award and won the award. We did this. In fact, we started from flywheel in laboratory to prototype to mass production. After all, one day, I will be able to stand here. I thought about something yesterday, and finally one day, the dream will come into reality. Today, several of my friends from more than ten years ago are here. We first started making this flywheel ten years ago. In the market, today we finally made our own Chinese flywheel. Honghui people have worked hard for 20 years to be here today. "Twenty years of sharpening a sword" is independent and controllable, in all walks of life, The cooperating units have paid a huge price and hard work, so that our next generation can look at the world. We are still doing this so that our next generation can look at the world. You are all working hard. The completion of this flywheel is a testament to Hong Kong. Hui large-scale manufacturing begins with our commercialization and verification of full service capabilities.

　　This photo is a real-life photo of our Chengdu project. Our flywheel UPS and generator set control system debugging capabilities are fully verified. This means that we already have such capabilities from design, execution, management and control to delivery. We can now say that we can look at the market and the world in terms of commercialization. In addition to the flywheel we just made and the UPS we just mentioned, we have actually made integrated solutions that are modular and adaptable to various scenarios. I was fortunate enough to chat with experts from the Academy of Sciences, and our system is used in a broad direction. This is a photo we went viral on WeChat Moments a few days ago. It’s called Bumblebee. It was actually the first day that the Chinese’s own flywheel was used on a power supply car. We put the box just now on the chassis to make a power supply car. This is what we made a thing. Thanks to Mr. Dai for this, he was the first person to eat crabs. We made the flywheel used on the oil drilling platform. We hope that Mr. Dai will carry it forward from the first day. This is our application on the PetroChina drilling platform. This is our system. play a role. Smooth power during storage and release. This is listed as a major project of PetroChina and Beijing Honghui International Energy as a major project in China's petroleum equipment industry. This can solve several problems. The first problem can be solved in the petroleum industry. In the past, We have to buy a Caterpillar generator from the United States. Now we can save at least one, and then the other one can be used. Suddenly we can overtake in corners, use the flywheel, and the expensive diesel generator solves the load problem. With the addition of the flywheel, we can Meet the characteristics of imported products. So in this case, it saves our country a lot of foreign exchange and the demand for imported imports. This is where it works very well. So this is a photo from the scene.

　　The first thing I just mentioned is that we made a UPS, and the second thing was energy recovery. The drilling platform is called energy recovery, large-scale energy storage. Large-scale energy storage is one thing that exactly fits today’s theme. This is what we We are currently cooperating with several units on the designed large-scale energy storage station plan to make the dream a reality and implement it. On the far left is the flywheel array, which has a 35 kV power supply. We drove 800 kilometers a day to inspect it. Several of our colleagues worked very hard, but we just wanted to put this matter into practice. Honghui Company’s largest Execution ability is the ability to put things into practice. I often say outside that Honghui Company does not have so much high technology. It just does rough work and implements one thing. When it is done, it is Honghui Energy.

　　I don’t need to talk about the application of large-scale energy storage. Many experts have talked about this matter. I am not here in vain. I will give you some useful information. There will be one later.

　　Flywheel energy storage is actually a lot of grid-connected frequency modulation and peak shaving. It is used in new energy, smoothing, and auxiliary frequency modulation. Many experts downstairs who want to know more about it have explained it very thoroughly. It can be used in thermal power frequency modulation and peak shaving auxiliary energy markets. It can accurately track and flywheel energy storage can do it, and it can be charged and discharged many times, unimaginable times. This is the characteristic of flywheel energy storage.

　　Now let me tell you one thing. As long as Honghui Company completes the energy storage, all these electronic functions will be taken care of. After the flywheel slows down, it can realize frequency conversion and voltage conversion. Our power grid has a fixed frequency of 50Hz. This matter It's very easy. So we have something unique in terms of control. The flywheel smart grid is at the system level. We think it is a combined technology. Everyone has products. The flywheel is integrated into the system as an original part. This is a bonus from me. place. Many of you here know a lot about batteries and have made a lot of batteries, but we have never heard data on the market about the integration of batteries and flywheels. Take a picture of this picture and forward it to your circle of friends. The majority of scientific and technological workers , have a good understanding of the voltage isolation technology, the battery and the flywheel. The voltage of the flywheel can be controlled very high, and the battery is fixed. In this way, I have an isolation interval, and I can accurately control when to discharge the battery. When the flywheel is discharged, when they are discharged together, in this way, a fusion of the battery and the flywheel can be achieved. What is fusion? It is hybrid energy storage. One is reflected in the rapidity of sprinters, and the reactivity can reflect the endurance of long-distance runners. In this case, these fast frequency modulation and peak modulation, quick response things, and high-frequency things are used in flywheels. , using batteries at low frequencies, thus achieving true grid-level balancing and finally realizing cost. We make real solutions available. I think this is the next step for our scientific and technological workers to work together.

　　What you can see in the picture on the right is that I drew a red color, drew a battery, and marked the battery. There has been a lot of research on flywheels, but not much research on flywheels and batteries. I hope everyone can study it together. What I said is true or false depends on the data. I want to talk about the picture on the left. I want to focus on this picture. The yellow part is the DC bus voltage. When I see the data in this picture, when I have a request When the external voltage drops, or when I need to discharge, the DC bus voltage actually drops suddenly when the battery is discharging. When it drops, in order to support the DC bus voltage, the battery quickly discharges electricity to support the DC Bus voltage, batteries often cannot handle this demand. If the quality is not good, problems may occur in an instant, such as fires and various other problems. In fact, they are often related to sudden power. But sometimes people dare to say it and sometimes they don’t. Said, but I think as science and technology workers, we have to seek truth from facts.

　　The second one is that if I put the flywheel and battery together, what will happen to the voltage isolation? That is, when you suddenly lose power or suddenly discharge to replenish energy, I can quickly adjust the current of the blue flywheel and support it quickly. Then the battery needs to be very small, so it is said to be very shallow. This kind of high frequency does not require batteries to do things. If they are combined together, I think the maximum utility and effect can be achieved. This is what I think we should develop next. This matter is very easy to verify. There is a flywheel on the A29 downstairs. Those who make batteries can contact us, and those who make power electronics can contact us. Move two flywheels back for experiments. If you don't get the data, come to me.

　　So what is the future of turning? There are many new technologies and new business formats that we don’t know what they are. What can we grasp? At present, at Honghui Company, we are making a flywheel. We can grasp this flywheel. We can do it well. This is what we can grasp. That thing that spins the world and spins the future is Honghui. What’s the saying? “If the mountains are not high, there will be immortals, and if the water is not deep, there will be dragons.” There are four dragons on our logo of Honghui Company. Honghui It means that the water surface is very large. When a dragon enters the sea, he hopes to achieve great things, so thank you all.
