Induction generator synchronization with grid | GoHz.com The current that the motor produces as a generator is produced in the rotor and passed to the stator by transformer action. The grid system can exports or In other words gents the sync is independent of speed. In addition, the active and reactive power balances in the induction generator can be written as follows: P produce = P absorbs Q produce = Q absorbs Induction Generator Modeling The induction generator modelling is derived from an ;Different from the grid-following structure, the doubly-fed induction generator (DFIG)-based wind turbine with a grid-forming structure has no coupling between the current loop and the phase-locked loop, and has a certain frequency/voltage active support ability, so it is more suitable for operation in the weak grid. It is simultaneously a lagging power-factor load and a unity power factor supply.". The induction generator has a squirrel cage rotor which draws magnetizing current from the stator giving rise to a high reactive power demand when fluxing, as when the generator circuit breaker is first closed. Drive Side: Left Hand Drive. A detailed model of the backlash in its gear-train which couples the wind turbine to the DFIG, has been derived based on a two-mass drive-train model.
