ABSTRACT

The use of induction generators in wind power application has become increasingly common, particularly in recent decades. A prime mover drives the rotor at a higher speed than synchronous speed in generator operation. On the basis of reactive power we can divided induction generator in two categories: first one is the standalone generator and second one is grid-connected induction generator. In the case of a grid-connected generator, magnetizing current is drawn from the grid, whereas in the case of a standalone induction generator, the magnetizing flux is produced by a capacitor bank connected to a machine. The base of induction generator is faraday's law of electromagnetic induction. If there is current flowing through the stator coil, then the stator will generate flux; as a result, the rotor will induce current. A gridconnected induction generator is the subject of this study, where frequency and voltage are determined by the grid. DFIG (dual-fed induction generator) wind turbines are one type of IG. They benefit from the capability to provide energy at a consistent voltage and frequency. In MATLAB-SIMULINK, we look at modern control approaches such as vector control and MFC (magnitude and frequency control) and model the performance of several systems.
