Wind turbine diagrams

Two main diagrams “wind turbine block diagram” and “wind turbine process flow diagram” have been used here to illustrate the operation principles of a wind turbine. The block diagram in a quite basic manner shows the major parts of a wind turbine and their interaction to extract the power from the wind.

In a more comprehensive manner the process flow diagram presents different systems including all the equipment and sensory devices in a wind turbine. How different items of equipment are related to each other and which kind of instruments are needed to control and monitor the wind turbine are included in this diagram.

It is suggested that these diagrams be used to link the primary components to, for example, VR representations for training. Each item could have a detailed description provided.
