Wind technology

01 / Wind technology

Variable rotor speed. Synchronous generation.

Some synchronous drivetrain architectures allow rotor speed to vary while the generator maintains a speed linked to grid frequency. Published designs use combinations of mechanical gearing, hydraulic systems and control equipment to achieve this.

Turbine platform considerations

Rotor geometry, machine rating and drivetrain architecture must be assessed together. Rotor selection depends on the wind conditions, loads and operating requirements of the site.

• Rotor geometry and site conditions
• Machine rating and drivetrain loads
• Operating and control requirements

Managing loads through the drivetrain

Torque limitation is central to the architecture. The gearbox and hydraulic system manage the relationship between rotor input and generator loading. The low-variable-speed extension broadens the operating range, with particular relevance to lower-wind applications.

Scaling wind technology

Moving from a prototype or mid-size platform to a larger turbine requires design work, validation and a site-specific connection assessment. Published development proposals should be read alongside the available operational evidence.
