Simulation-Based Design of Wind Turbine
FEA & CFD Based Simulation Design Analysis Virtual prototyping MultiObjective Optimization
In order to test Wind turbine capabilities and assess the risks of failure, numerical modeling is essential for manufacturers. Physical tests are expensive and only possible in limited circumstances due to the size of wind turbines and the lack of control of the wind conditions. Enteknograte offers virtual prototyping with FEA and CFD service helping wind energy companies address these challenges and understand the intricacies of design and the interactions of the sub-systems during the different environmental conditions as well as the physics of the materials to manufacture components in a cost efficient way.
Mechanical Components reliability
Enteknograte’s FEA and CFD based design and optimization solutions enable the dynamic simulations of the mechanical system (gearbox, transmission) accounting for the flexibility of the supporting structure. This enables to predict the lifetime and the risk of failure for what represents the first cause of loss of Wind turbine.
Wind Turbine Noise
Radiated noise is a major concern when planning wind turbines, including noise produced by the blades and the noise radiated from the nacelle. Enteknograte proposed solution with using ESI VA ONE and MSC Actran, includes a wide range of modeling options, such as CFD with moving components, SEA (Statistical Energy Analysis), FE (Finite Element), BEM (Boundary Element Method) and hybrid FE/SEA (Finite Element/Statistical Energy Analysis), to determine near and far field radiation from panels and openings.
Manufacturing of Wind Turbine Blades
With the continuously growing dimensions of Wind turbine, the manufacturing of very large blades has become a serious challenge for the industry. The traditional physical trial-and-error process is becoming financially inefficient. Enteknograte ’s FEA and CFD based Virtual Manufacturing solution with combination of advanced numerical tools offers an effective alternate approach to the optimization of the manufacturing of very large blades.
Power fluctuation is one of main is one of the main issues in connecting wind farms to the power network. While an increasing number of utilities are requesting from the manufacturers to provide clues about the level of fluctuations, these can usually only be provided after testing full-scale prototypes in real wind conditions. Enteknograte use numerical models to simulate natural wind model that matches the statistics of wind profiles and wind gusts that can be applied to realistic models of the Wind turbine to predict the power fluctuations before the first prototype is manufactured.
