ANSYS
TENERGISING HE WIND INDUSTRY
Increased complexities require a system-level approach in designing and evaluating wind turbines.
Wind energy projects around the globe — from small installations to very large wind farms — have a common goal: to reduce unit energy cost while improving reliability.
From a business perspective, technology contributes to viability by influencing efficient wind turbine design, manufacture, deployment and operation. Whether the application is an onshore, offshore or far-shore installation, advancements in science and engineering will contribute to the industry’s success, especially through capabilities related to aerodynamic design, material science, structural design, electronic mechanical control, site selection and farm layout.
INCREASING COMPLEXITY AND ENORMITY Wind turbines and wind energy projects are becoming increasingly more complex, so they must operate dependably at levels unimaginable a few years ago.
Installations of very large wind turbines in offshore and floating configurations are a major technological achievement. Energy companies hope to design, install, and efficiently and reliably operate superstructures whose wind blade spans are over 50 metres and subject to wave and wind loading at different angles of attack.
SIMULATION SOFTWARE Historically, wind energy companies have used engineering simulation software as a point solution, used only to simulate a specific design aspect or analyse a component. Successful applications such as ANSYS solutions range across the wind energy industry, including:
• Aerodynamic design: thrust coefficient, blade structural integrity, ultimate loads and fatigue, noise predication, wind gust fluid–structure interaction, bird strike, icing, boundary layer transition, near-wake and far-field studies
• Structural design: tower and rotor structural integrity/safety, power conversion efficiency, installation cost and maintenance, offshore transport and installation
• Component design: blades, gearboxes and bearings, generators, nacelles, rotors, drivers, motors, electronics cooling
• Site selection and farm layout: maximum project potential, power output (both peak and average), wind loads, fatigue
• Turbine placement: variable terrain, roughness, forestry, multiple wake effects, buildings and setbacks
• Electromechanical system: electrical machines, variable-speed control systems, transformers, power electronics, power distribution, sensor and actuator design
• Blade manufacturing
