This paper presents a predictive current control strategy for Active Front End (AFE) rectifier supplying active and reactive power to the electric system during unsymmetrical voltage fault conditions without the use of a Phase Locked Loop (PLL) or Frequency Locked Loop (FLL). For a given active and reactive power and supply voltage, the strategy generates the required reference currents. A predictive...
Today, it is common the use of a static power converters to adapt the available energy from a clean source to feed an electrical load. Wind energy conversion systems have become one of the principal areas of research on renewable energies. This research has permitted the development of different topologies and control strategies of power converters to be used on wind energy extraction. This paper...
A sliding mode control scheme is presented in alphabeta frame for grid-side PWM rectifiers in wind power generation systems. The positive and negative sequence voltages are needed to design the controller, nevertheless, the positive and negative sequence currents are not needed. This scheme is compared with the dual current control scheme in the rotating frame d-q. The simulation results show that...
