GL Garrad Hassan also offers some neat tutorial videos on their . In addition to providing step-by-step instructions on how to use the Bladed software, these videos also explore some of the theory behind wind turbine operations and control.
The complete list of Bladed tutorial videos is as follows:
The first three videos introduces the layout of the Bladed user interface along with how to perform calculations and display outputs.
The fourth video, "Basic Turbine Control', provides a clear overview of the principles of VSPR (variable speed pitch regulated) control strategies. The video also includes a clear derivation of the Optimal Mode Gain value, a critical parameter for variable speed control operation.
