asynchronous squirrel-cage induction generator directly connected to the grid via a transformer. Since the squirrel-cage induction generator always draws reactive power from the grid, this configuration uses a capacitor bank for reactive power compensation. Type B: Limited variable speed wind turbine. This one uses a wound rotor generator with variable generator rotor resistance and pitch control, which allows for a speed range of up to 10% above the synchronous speed. Type C: Variable speed wind turbine with a doubly fed induction generator (DFIG) and pitch control. This concept allows a wider range of dynamic speed control compared to Type B, depending on the size of the frequency converter. Type D: Variable speed and

Each part was created using different combinations of carbon fiber, resin and methodsof resin injection. The end result attained is the level of quality desired (Figure 3). The studentsuse RP machines as a tool to front-load the design and engineering process, leaving more timefor manufacturing considerations.

After the material cools and the field is removed, theWeiss domains roughly remain in alignment. As a result, the material now has its own polaritywhich can be degraded by exceeding the mechanical, thermal, and electrical limits of thematerial. Subsequently, there is a growth in the direction parallel to the polarization and acontraction in the direction
