For birds, offshore wind power and land-based wind power are new dangerous electric fans on the earth. Therefore, while developing renewable energy sources, we should also consider the feelings of local or migratory organisms. Therefore, Oregon State University (OSU) ) Develop an intelligent system that hopes to analyze and reduce the impact of wind turbines on birds.
According to the UN News 2014 report, compared to coal-fired power generation, wind and solar energy have less impact on birds. Between 140,000 and 328,000 birds die each year from wind energy in the United States, and coal-fired power generation causes about 7.9 million bird deaths. However, this is only a comparative problem. It is also a lot of 300,000 people. It cannot be neglected easily, especially the protected and rare white-headed sea eagles and golden eagles.
OSU research team developed a sensor integration system to detect the effect of wind turbines on birds and make statistics more perfect. Roberto Albertani, assistant professor of mechanical engineering at OSU, said that in the past, artificial inspections and long-term monitoring were used to assess bird mortality. In the event of an impact, but it is unavoidable that there will be mistakes in manpower, and for remote and offshore wind power, manual detection is not only costly, but also difficult to reach in some places.
The system consists of a vibration sensor on the blade, an acoustic sensor and an optical camera on the pile. It can accurately determine the impact on birds and can even distinguish different species of birds. When the vibration sensor detects During a heavy blow, you can check the camera and record whether the Hawk or other creature and the wind turbine had a 'car accident'.
In order to test the research, the researchers used the launch of a tennis-sized “air cannon” (compressed-air) to simulate a bird impact at the National Research Center for Renewable Energy (NREL) Wind Science and Technology. The vibration sensor performs well, not at every Sensors are installed on each blade. Albertani pointed out that the middle blade and the leading edge of the blade are easier to be sensed by sensors.
The team also hopes to use new technologies in the future to shake the oncoming birds and allow the birds to co-exist peacefully with wind turbines. The U.S. Department of Energy Efficiency and Renewable Energy (EERE) is also supporting this research if the eagle is moving towards the wind turbines. Flying, the Smart Connected Camera instantly triggers the kinetic deterrent: constantly moving colorful humanoids to maximize the eagle’s sense of disgust towards 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.
