Defining the Generator Model

A wind turbine electric generator is driven by the drive shaft and turns a set of copper windings through a magnetic field generating electricity and applying a counter air-gap torque to the drive shaft. Bladed supports the option of a variable speed generator. This type of generator is generally used in more modern wind turbine concepts to enable constant tip speed tracking for optimal rotor performance during the torque control power production mode of operation.

Generator Models

The generator characteristics must be provided if either the dynamic drivetrain or direct drive transmission options are selected. A single type of generator model is available:

• A variable speed generator model for variable speed turbines.

The user can also define electrical losses to represent the efficiency of electrical power conversion within the generator.
