Simulation Studies of Control Systems for Doubly Fed Induction Generator Supplied by the Current Source Converter

In this paper, double PWM converter AC excitation system of the variable speed constant frequency doubly fed induction generator (DFIG) for wind power generation is taken as the research object. At present, most vector control systems of rotor-side PWM converter adopt feedforward compensation to realize the purpose of power decoupling control. The decoupling effect is greatly affected by the power changes. A power decoupling control strategy based on auto-disturbance rejection control (ADRC) is proposed. The decoupling control between active power and reactive power is realized by observing the coupling term and the total disturbance of the d-axis and q-axis components of the stator current and the stator voltage with the extended state observer and compensating. Simulation analysis and experimental test show that, on the basis of vector transformation, the rotor-side PWM converter power decoupling control based on ADRC has a small overshoot and fast dynamic response when tracking the change of wind turbine input power, which can achieve the decoupling control between active power and reactive power well. The system has strong robustness and adaptability.

Aims: This paper presents the control of the output torque of SCIG using indirect vector control (IVC) technique. Study Design: IVC is very popular in industrial applications, which doesn’t rely on the measurement of the airgap flux because the devices that used to measure the air-gap flux is inaccurate in low speed. The IVC technique has been presented to control the torque of the generator and maintain the flux unchanged. Methodology: The performance of the proposed system is tested using MATLAB/SIMULINK. Results and Conclusion: Simulation results are introduced showing improvement control system performance.

“…Various control techniques for induction generators have been proposed in [5]. The most common methods are based on DC-link voltage control [6], space vector control in [7], and direct torque control (DTC) [8]. Most of the presented techniques for power control of induction generators are based on pulse-width modulation (PWM) and use proportionalintegral (PI) regulators.…”

A synergetic sliding mode (SSM) approach is designed to address the drawbacks of the direct field-oriented control (DFOC) of the induction generators (IGs) integrated into variable speed dual-rotor wind power (DRWP) systems with the maximum power point tracking (MPPT) technique. Using SSM controllers in the DFOC strategy, the active power, electromagnetic torque, and reactive power ripples are reduced compared to traditional DFOC using proportional-integral (PI) controllers. This proposed strategy, associated with SSM controllers, produces efficient state estimation. The effectiveness of the designed DFOC strategy has been evaluated on variable speed DRWP systems with the MPPT technique.
