Review on Permanent Magnet Synchronous Generators Connected to the Grid: A Comparison of DC and AC Setups

Kartik Ingole

Abstract


An active rectifier stage (ac/dc stage) control strategy is presented in this study for a micro wind application using a permanent magnet synchronous generator that is part of a grid-connected low-power system (PMSG). In specifically, an adaptive low-pass filter paired with a feed-forward compensator was used to construct a new approach for the prediction of the PMSG rotor angle that relies on flux estimators. As a result of having the flux estimator's data preloaded, the PMSG was able to start up extremely quickly and reliably. The goal of the grid-facing side of wind turbines is to optimise electricity distribution to the grid from wind energy production. Underestimating the potential of a fully-controlled wind turbine with an induction generator and a back-to-back converter. In addition to supporting reactive power adjustment and functioning despite grid interruptions, this setup also allows for complete command of the electrical torque and speed. The suggested solutions have been shown to be successful in simulations and experiments, with maximum power transmitted to load and minimal overall grid current harmonic distortion.
