<p class="p__0">Ideally, induction generators work best in the stable area in between the no-load condition and maximum torque area. More Discussion Posted Here [modify] The optimal power that can be produced by an induction motor ran as a generator is restricted by the ranked present of the generator's windings. Grid and stand-alone connections [modify] Typical connections when utilized as a standalone generator In induction generators, the reactive power required to establish the air gap magnetic flux is supplied by a capacitor bank connected to the device in case of stand-alone system and in case of grid connection it draws reactive power from the grid to maintain its air gap flux.</p>

<p class="p__1">For stand-alone systems, frequency and voltage are complex function of machine specifications, capacitance used for excitation, and load value and type. Induction generators are frequently used in wind turbines and some micro hydro installations due to their ability to produce useful power at varying rotor speeds. Induction generators are mechanically and electrically simpler than other generator types.</p>

<p class="p__2">Limitations [modify] An induction generator linked to a capacitor system can produce sufficient reactive power to operate on its own. When the load existing surpasses the capability of the generator to provide both magnetization reactive power and load power the generator will immediately cease to produce power. The load should be eliminated and the induction generator rebooted with either a DC source, or if present, residual magnetism in the core.</p>

<p class="p__3">Unlike synchronous motors, induction generators are load-dependent and can not be utilized alone for grid frequency control. Example application [edit] As an example, think about using a 10 hp, 1760 r/min, 440 V, three-phase induction motor as an asynchronous generator. The full-load current of the motor is 10 A and the full-load power factor is 0.</p>
