ANSYS
SYSTEM LEVEL APPROACH Today’s increased complexities require a system-level approach in designing wind turbines and evaluating performance based on real-world conditions.
Advances in engineering simulation software increasingly make this possible. Modern simulation software is designed with capabilities that enable modelling entire wind turbine systems.
Its value is further enhanced through advanced solver functionality including turbulence transition models, advanced contact models, multiphysics capabilities, composites tools, high-performance computing and the flexibility to connect to third-party software for wind turbine blade manufacturing or aero-elasticity calculations.
SYSTEM-LEVEL ANALYSIS Engineers can perform electromechanical system-level analysis, electromagnetic analysis on electric machines and drives, wind power analysis, and stress and modal analysis.
By leveraging high-level integration and advanced capabilities engineers over time are extending their once-simplified simulations to include additional details in overall wind turbine design — enabling small efficiency gains, important in an industry in which a minute efficiency/ performance gain can translate into much larger electricity production, reduced downtime and greater project profitability.
RELIABILITY AND OPERATION Such details can also improve reliability and enable better wind energy project operation. Already, there are many exciting examples of the expanding use of engineering simulation throughout the wind energy supply chain.
FUTURE NEEDS With increased demand for wind energy, engineers will face additional complexities, such as even-larger turbine blades that will be installed farther offshore and in harsher environments. Wind farm site selection must continue to reduce risk and overcome proximity and environmental concerns. New powertrains, lighter towers, multi-access turbines, floating platforms and quieter machines will be developed.
The industry will innovate to meet the challenges of increased safety and reliability, improved remote monitoring, reduced system maintenance and regulatory concerns.
ANSYS, as an example, is keeping pace by providing high-fidelity integrated, advanced capabilities that meet single- physics needs as well as system-level and multidisciplinary requirements of the wind energy industry.
