For birds, offshore wind power and land-based wind power are newly emerging dangerous electric fans on the earth. Therefore, while developing renewable energy sources, they should also be aware of the experience of land-based or migratory organisms. Therefore, Oregon State University (OSU) Develop a smart system that hopes to analyze and reduce the impact of wind turbines on birds.
According to UN News 2014, wind and solar energy have less impact on birds than coal-fired power generation. In the United States, between 140,000 and 328,000 birds die each year due to wind energy, and coal-fired power generation causes about 7.9 million bird deaths. However, this is only a comparative problem, and 300,000 are also many, and this issue cannot be easily overlooked, especially when it is protected. Rare white-headed sea eagles and golden eagles.
To this end, the OSU research team developed a sensor integration system that can detect the effects of wind turbines on birds and make statistics more complete. Roberto Albertani, assistant professor of mechanical engineering at OSU, said that in the past, manual inspections and long-term monitoring were used to assess bird mortality and impact events, but man-made unavoidable mistakes were made. In remote areas and offshore wind power, manual inspection was not only costly, but also Local humans are also hard to reach.
The system consists of a vibration sensor on the blade, an acoustic sensor and an optical camera on the pile, which can accurately determine the impact on birds and even distinguish different species of birds. When the shock sensor senses a critical hit, the camera can be inspected and recorded as an “auto accident” between the Hawks and other creatures and fans.
For the test study, the researchers used a tennis-sized “air-gun” (compressed-air) to simulate a bird impact at the National Renewable Energy Research Laboratory (NREL) Wind Science Center. The vibration sensor performs well and does not have to be Sensors are installed on the blades. Albertani pointed out that the middle blade and blade leading edge are easier to be sensed by sensors.
The team also hopes that new technologies will be available in the future to shock the oncoming birds and allow the birds to co-exist peacefully with the wind turbines. At present, the US Department of Energy Efficiency and Renewable Energy (EERE) is also supporting this research. If the eagle is flying toward the fan, the smart networked camera will instantly trigger the kinetic deterrent: constantly moving colorful humanoids. In order to maximize the eagle’s sense of disgust toward humans.
At present, these concepts are still in the preliminary stage, but they still have great potential for development. After all, everyone hopes that renewable energy can coexist with the environment. This is also the core value that people have to start developing green energy.
