This article proposes a modeling approach and an optimization strategy to exploit third-harmonic current injection for the torque enhancement in multiphase isotropic permanent magnet synchronous machines with nonsinusoidal back electromotive forces. The is based on proper vector space decomposition associated rotational transformation, aimed properly select set of stator vectors be controlled. ...

As the inverter-based generation replaces conventional synchronous generators, it may also need to fill in missing ancillary service support. One of these services is dynamic reactive power provision and voltage control. This paper analyzes optimal strategy active fault-current support leading fast recovery system. For purpose analysis, new ramping current controller able emulate different beha...
