“…The corrector must first, control the mechanical speed to its reference speed, and secondly, generate an electromagnetic torque considered as being the image of the reference current of the DC motor. DC motor current control provides the control signals, which are generated by the dSPACE DS1104 interface device directing the semiconductor switches of the arms constituting the DC/DC converter which feeds the DC motor [18][19][20][21][22]. In this case, an optimal torque is generated and applied to the mechanical shaft [18,19].…”

In this paper, an experimental study of a Wind Energy Conversion System (WECS) is performed. A test bench with a power of 1.5 kW is setup. The system consists of a Doubly-Fed Induction Generator (DFIG) and a wind emulator based on a DC motor associated with a Maximum Power Point Tracking (MPPT) control. The proposed emulator is driven by a four quadrants DC/DC converter to produce a real wind turbine behavior. The aim of this work is to improve the DIFG performances by using the fuzzy logic-based intelligent controller. This control technic is designed to monitor the stator reactive and active powers. This can be achieved by the DFIG rotor side converter (RSC) using the field-oriented control. The experimental setup uses a dSPACE DS1104 device, MATLAB/Simulink software and a ControlDesk interface. The paper shows that, the desired amount of active and reactive powers has been independently controlled and the implementation is successfully verified the effectiveness of the proposed control scheme achieved using the FLC strategy.

“…Most studies use AC/AC converter only in the rotor side to control the generated powers, making the electronic power converters and power loss less than those of conventional full-size stator converters. The DFIG is able to operate under different modes (sub, super and synchronous modes), it offers also: decoupling control of active and reactive powers, operating in wide range of speed and ability to deliver a large amount of energy [2][3].…”

The main objective of this paper is the performances analysis of an Enhanced Direct Power Control (EDPC), applied to Doubly Fed Induction Generator (DFIG) driven by variable speed Wind Turbine (WT). This control strategy uses hysteresis regulators and switching table for active and reactive powers control. These latter are estimated using rotor currents and grid voltages instead of a traditional measurement of stator currents. In addition, the EDPC switching table is based on the position of the rotor flux instead of the stator flux in order to have better regulation accuracy because the rotor voltage vector directly influences the rotor flux and has a proportional relationship with the active and reactive powers. All the operating modes (sub-synchronous, super-synchronous, synchronous and over-speed) of the variable speed WT-DFIG system and the possibility of local reactive power compensation are reported and discussed in this paper. Depending on the operating zone of the WT, Maximum Power Point Tracking (MPPT) technique and pitch angle control are considered to optimize the wind energy efficiency. The validation of the proposed EDPC strategy has been performed through simulation tests under MATALB/Simulink, the obtained results show robustness and good performances with low THD of the generated currents.

“…Owing to the diminution of fuel fossil reserves and increased concern about CO2 emissions, which can cause a critical climate change, the wind energy systems (WESs) have become attractive and developed rapidly over the last few decades as a clean renewable energy source (Barra et al, 2016 ; Kumar, 2016 ; Soued et al, 2017 ). Despite the impacts of Covid-19, the most exclusively published statistics energy has appeared that the total additions of wind energy capacity in 2020 are expected to reach 65 GW, which increased by 8% compared with 2019 (Jaladi et al, 2020 ; Sadorsky, 2021 ; Slimane et al, 2020 ).…”

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