Study On The Deformation Mechanism And Control Of Wind Turbine Over Mining Subsidence Area

Mining subsidence inevitably harms the wind turbine on the mining area, whichdirectly threats the wind turbine safety operation. The safety of the wind turbine towerand foundation is a king link to guarantee the wind energy. It has important practicalsignificance and significance of scientific research to in-depth study the influence lawof wind turbine on the mining subsidence.This paper combines the structural characteristics of wind turbine and the generallaw of mining ground surface deformation, analyzes the mining deformation influenceof wind turbine. Utilization of theory and ANSYS numerical simulation study theanti-surface deformation of the wind turbine tower, and gets the extreme tilt of thewind turbine tower. Establish the finite element model of the wind turbine foundation,and study the anti-surface deformation of it, and obtains the extreme of the surfacedeformation and curvature of the foundation. According to the mining under the windturbine, proposed corresponding mining and ground corrective measures. Combinedwith Zheligentu wind farm in Mongolia Baoligen Coal Mine, design the miningprograms.
