This paper presents fuzzy logic control of Doubly Fed Induction Generator (DFIG) wind turbine in a sample power system. DFIG consists of a common induction generator with slip ring and a partial scale power electronic converter. Fuzzy logic controller is applied to rotor side converter for active power control and voltage regulation of wind turbine. Wind turbine and its control unit are describ...

In this work, we are interested in improving the performance of a doubly-fed induction generator (DFIG)-based wind system, by applying sliding mode control strategy. The objective is regulation active and reactive power, also voltage frequency signal injected into distribution network. model proposed for based on technique with estimators. was validated simulation MATLAB/Simulink.

This paper presents a novel current control methodology for grid connected doubly-fed induction generator (DFIG) based wind energy conversion systems. Controller is based on a proportional controller with additional first order low pass filter disturbance observer which estimates the parameter dependent nonlinear feed-forward terms. The results in simulations and experimental test bed obviously...

Variable speed generator systems (VSGs) are at work in the now 600 GW installed wind power plants (parks). Also, they used as vehicular and on ground stand-alone generators. VSGs imply full kVA rating PWM converters permanent magnet (PM) or electrically excited synchronous cage rotor inductance But, to reduce cost absence of PMs a reasonable initial (weight) efficiency, fractional converter dou...

<p>The work presents the dual-rotor wind energy conversion system (DRWECS) with a direct driven doubly-fed induction generator (DFIG). The consists of turbine (DRWT) DFIG, grid side converter (GSC), and machine (MSC). To command MSC, power (DPC) based on genetic algorithm (GA) classical pulse width modulation (PWM) has been applied. achieve maximum from DRWT, powe point tracking (MPPT) te...

With the gradual increase of wind power penetration in system, impact farm on system stability is becoming more significant. This study designs stabilizer (PSS) based model reference adaptive control (MRAC) method and virtual impedance (VI) strategy. Then, active difference doubly fed induction generator (DFIG) selected as input signal MRAC-PSS-VI. The small-signal with DFIG enhanced by install...

For grid-connected DFIG-based wind turbine, Fault Ride Through (FRT) or Low Voltage (LVRT) capability is vital problem that need to be improved. This paper proposes an Active Disturbance Rejection Control (ADRC) strategy applied Doubly Fed Induction Generator (DFIG) based Wind turbine (WT), which integrates a Dynamic Restorer (DVR).

The paper presents a super-twisting sliding mode (STSM) regulator with neural networks (NN) of direct power command (DPC) for controlling the active/reactive power of a doubly-fed induction generator (DFIG) using a two-level space vector pulse width modulation (2L-SVPWM). Traditional DPC strategy with proportional-integral (PI) controllers (DPC-PI) has significantly more active/reactive power r...

Variations in generator parameters that occur during the operation of a doubly-fed induction wind turbine (DFIG) constitute significant factor degradation control performance. To address problem difficulty identifying multiple simultaneously DFIG, parameter identification method depending on adaptive grey wolf algorithm with an information-sharing search strategy (ISIAGWO) is proposed to solve ...

Doubly-fed induction generator is widely used in wind turbine conversion systems. Several research works are being made to efficiently approve existing condition monitoring and fault detection techniques for these systems. The condition monitoring of these systems becomes more and more important, the main obstacle in this task is the lack of an accurate analytical model to describe a faulty DFI...
