Induction Generator - Grid and Stand-alone Connections

Grid and Stand-alone Connections

In induction generators, the magnetizing flux is established by a capacitor bank connected to the machine in case of stand alone system and in case of grid connection it draws magnetizing current from the grid.

For a grid connected system, frequency and voltage at the machine will be dictated by the electric grid, since it is very small compared to the whole system.

For stand-alone systems, frequency and voltage are complex function of machine parameters, capacitance used for excitation, and load value and type.
