Modeling and MPPT control of squirrel-cage induction generator wind power generation system via VisSim

Based on the mathematical model of the SCIG wind power generation system, a model of the system for maximum energy capture was established using MPPT in VisSim. In the double loop of control system, a PI speed controller is adopted in the speed loop, and a vector controller is used in the current loop. The validity is testified by the simulation results, and other control strategies can be applied to the system to testify their rationality, and the VisSim supplies a new method for the simulation of SCIG wind power generation system.
