| Abstract: | The East and Southeast Asia region has shown a great push towards wind energy in the past decade and has become the largest market for wind turbines. That part of the world is unfortunately subject to multiple typhoons each year, a natural disaster that can destroy entire communities. The extreme wind speeds that occur in these storms can easily damage or dismantle wind turbines. This represents a huge risk that has to be taken into account when designing a turbine that would be located there. 2B-Energy is a company based in Hengelo which designed and implemented a downwind two-bladed wind turbine, the 2B6 turbine, installed in Eemshaven (The Netherlands). As the Asian market shows much potential, having a strong load management strategy to preserve the turbine is crucial when installed in an area prone to tropical cyclones. The strategy investigated concerns the position of the rotor during extreme wind speeds, which can be left idling or parked. To assess the optimal configuration, aeroelastic simulations were ran to determine which option could potentially have the lower loading on the different wind turbine components. For these simulations, different wind fields were generated in order to simulate a typhoon. Some of the parameters implemented in the wind field were based on experimental data of typhoon Yagi from 2024. The simulation results pointed out different behavioral differences between the idling and parked rotor. The parked configuration lead to a large yaw misalignment while the idling configuration caused larger loads. A static rotor position seems to avoid the most extreme loading on the turbine’s components. To implement this particular strategy, different design consideration such as the use of an active yaw mechanism need to be further investigated as simply locking the rotor, when having a damped passive yaw system, might not be beneficial. |
