9. Methodology

This section introduces the model of the wind turbine while analyzing all three blocks. The equations used in the design model for each block are derived and analyzed as well. The wind energy conversion system modeling is reduced into three subsystems which are the aerodynamics block, mechanical block, and the electrical block as shown in the block diagram in Figure 3.

The aerodynamics block is responsible for the extraction of power from the wind in the form of kinetic energy necessary to propel the blades. The mechanical block then converts this kinetic energy into mechanical energy used to drive the generator which in turn is turned into electrical energy by the electrical block.

The modeled wind turbine system is designed and simulated with the MATLAB SIMULINK software. The simulation model diagram showing all three subsystems is shown in Figure 4.
