Abstract
Wind-power generation is one of the fundamental sources of renewable energy. However, due to the increasing size of wind turbines, they cause unwanted interference with radar systems for civic protection, especially for on-shore locations. This paper presents parameter studies performed on different wind-turbine models, with a focus on differences of the aerodynamical shape of the rotor blades. Numerical simulation is employed to estimate the influence of different wind-turbine design parameters, with the aim of deriving strategies to minimize wind-turbine influence on radar systems for civic protection. Due to the complex nature of the aerodynamic shape of the blade, a general model cannot be derived from the studies. However, further steps to eventually achieve this goal are outlined.
Highlights
For more than 20 years, wind power use is expanding in Germany and other countries in order to increase the regenerative and, sustainable production of electricity
In addition to large off-shore locations, further allotments of on-shore locations as well as “repowering” activities will be necessary in order to fulfil the goals of reducing the carbon footprint as prescribed by the German Climate Protection Plan [2]
An additional field of conflict is the fact that radar systems and wind turbines have overlapping requirements for their location: places that are good for radar installations usually are well-suited for wind turbines [3,4]
Summary
For more than 20 years, wind power use is expanding in Germany and other countries in order to increase the regenerative and, sustainable production of electricity. An additional field of conflict is the fact that radar systems and wind turbines have overlapping requirements for their location: places that are good for radar installations usually are well-suited for wind turbines [3,4]. This is true for radars for aviation safety, where air traffic surveillance radar is negatively influenced by wind-turbine clutter [5,6]
