WebThe closed-loop DFIG system is faster than wind turbine control systems such as pitch control. Therefore, a low fidelity lumped DFIG generator system is practical for improving simulation speed and providing flexibility. The lumped generator system integrates with the wind turbine system to simulate different aspects of the control algorithm.
