The advantages of wind turbines are obvious unless you are not on the air traffic commander. This is because on the air traffic management radar screen, the running wind turbines and the flying aircraft look very similar, which may lead to aviation accidents because the traffic administrator may overlook the aircraft on the main display, and this will also Exposed the weakness of the national air defense system. Dorothy Robin, the US Department of Defense’s assistant director of the environment, once stated that the dangers of wind turbines cannot be sustained for national security and military training in certain regions. Recently, a startup company called Aveillant brought a new solution to this problem. The 3D holographic radar can accurately distinguish between aircraft and various types of wind turbines.
All-image Radar Solving Wind Turbine Interference Problems
The development of 3D all-in-one radar has received support from airport operators, wind farm developers, the UK Department of Energy and Climate Change and the Department of Defense. Traditional radars scan narrow beams of light only within the air traffic commander's field of vision, marking each object and recording its position. Unlike conventional radars, the all-image radar is a 3D radar that can realize continuous tracking. It does not require scanning to perform full-range monitoring, coherence tracking, and behavior analysis. Since an all-image radar can continuously track a range, it can distinguish moving objects from static objects.
It is reported that there are other uses for full-image radar. Cambridge Consulting is currently testing the technology's ability to track high-speed launch cannons. In addition, the technology can also be used to remove mines. Cambridge Consulting has been studying wind turbines' interference with radar since 2007 and launched a small-scale test in the UK that year. Recently, the company is providing system design for wind turbines located near Glasgow Airport in Scotland. Currently, Aveillant has three funders, namely Cambridge Consulting, DFJ Esprit and Aviation Investment Funds. Cambridge Consulting is an engineering and product development company with leading Bluetooth development technology and has established more than 20 companies in 50 years of creation. Due to the importance of this technology and the impact of wind turbines on the radar, currently 66% of wind farms in the UK are in a stagnant state. This part of the idle installed capacity reaches 6.5 GW, which is equivalent to 600,000 private cars, 2 Billion refrigerators and 60 million light bulbs provide energy. The company plans to attract millions of investments in the next nine months to accelerate the commercialization of all-image radar in multiple countries.
New technology is favored
Aveillant does not present the cost of the full-image radar, nor did it disclose the target consumer market for the product. However, Aveillant stated that the United States and the United Kingdom have shown strong interest in this. Currently, Aveillant is negotiating with some airport and wind turbine developers from the United Kingdom and the United States. Aveillant founder Oswald said: "Aveillant has ushered in its first customer and is expected to unravel the wind power development difficulties to help the UK achieve its low-carbon goals."
Oswald said: “The wind power industry needs an all-image radar, and this demand is very urgent. The invention of an all-image radar can solve a major constraining problem for wind energy development.†It is reported that the global installed capacity of new wind turbines is expected to have an installed capacity More than 20 million kilowatts, governments and countries are making great efforts to develop sustainable renewable energy. The United Kingdom plans to increase wind power capacity to 30 million to 40 million kilowatts by 2020. In the future, Aveillant will mainly provide equipment and services for products to better solve the conflict between wind generators and radars. This technology will meet both civil and military requirements. In addition, this will create more green jobs. At present, Aveillant is improving on the basis of existing technologies. In the future, new solutions will be able to identify small aircrafts in a large range of large-scale wind turbines, and its accuracy will be further improved.
Orland Duncan, managing partner of DFJ Esprit, stated: “The demand for renewable energy is a global issue. Many countries in the world have set targets for renewable energy development. Aveillant has provided us with this investment opportunity. It can solve the problems of wind turbine development through 3D radar, and at the same time create more possibilities for the development of wind power." Simon Chrisding, president of Aviation Investment Fund, said: "The new technology will lift the impact of wind turbines on radar, we We are pleased with the progress of this technology. In addition, Aveillant's solution does not cause any loss to the existing system. We look forward to the final promotion of this technology."
There have been similar technologies earlier
In fact, people have long been concerned about the interference of wind turbines with radar signals. In 2009, QinetiQ and Danish wind turbine manufacturer Vestas spent 5 years working together to develop a "stealth turbine." The surface of the turbine is coated with a coating capable of absorbing radar. The birth of this product has revived many wind farms that have been shelved due to radar interference problems. At the time, Mark Roberts, director of energy and environmental strategy at Quinnet, said: "The 'hidden turbine' may be helpful, but it cannot completely solve the problem of interference."
Mark Roberts mentioned that it is impossible to completely solve this problem immediately by using only one method, because each wind farm has unique features such as the number of turbines, geographical location, distance from the radar, etc. Wait. Although it cannot be said that the “hidden turbine†is a panacea, it at least indicates that researchers have taken a big step towards solving the problem. He said: “The biggest disturbance to radars on wind turbines is the blades, because they will keep turning, so we put a thick layer on top of it. From an effect point of view, it will no longer have a negative impact on the aircraft. Become 'invisible'.
