Finite-State Predictive Current Control of a Standalone DFIG-Based Wind Power Generation Systems: Simulation and Experimental Analysis

This paper presents an improved stator voltage magnitude and frequency control for standalone doubly fed induction generators (DFIGs) based wind power generation systems (WPGSs). The proposed technique uses a simple finite-state predictive current (FS-PCC). In this method, the switching vector IGBT is selected to minimize error between reference value predicted of rotor current. Moreover, discrete-time models (DFIG) are needed predict future all possible vectors generated by rotor-side converter (RSC). Since classic methods in literature use inner loops on pulse width modulation (PWM), method does not require complex stages omits loops, which reduces requirements. main objective DFIG system keep has constant amplitude equal value, regardless changes speed or load. strategy was implemented through 3 kW prototype platform-based dSPACE 1104 card. simulation experimental results show that FS-PCC offers excellent tracking with less total harmonic distortion (THD) voltages currents.
