Abstract:
This paper proposes a small stand-alone wind energy conversion system (WECS) with a reduced number of sensors. Many different wind energy conversion systems have been proposed in the literature. However most of them need many current and voltage sensors in order to setup the control system: In the conventional WECSs, there are many sensors used; six sensors for the input currents and voltages and two sensors for the MPPT and one sensor for the inverter stage. The main contribution of this paper is proposing a new WECS with only 66% from the total number of sensors required in the conventional system. The proposed full system includes a wind turbine connected to a permanent magnet syn-chronous generator (PMSG), full controlled rectifier with maximum power point tracking (MPPT) and hysteresis cur-rent control, DC-link represented by DC/DC bi-directional converter with a battery, and a hybrid pulse width modulated (HPWM) H-bridge inverter connected to the AC load. The proposed system has been investigated by simulation and experimental results. The controller different stages have been configured on a floating point DSP (TMS320F28335). The simulation of the complete system has been implemented in PSIM program.
