This paper proposes a competent and effective scheme to enhance the ride-through capability of DFIGbased wind turbines under unbalanced voltage dip conditions. The proposed method is realized through joint use of the rotor-side converter control and a three-phase stator damping resistor (SDR) placed in series with the stator windings. By means of an asymmetrical SDR idea, during the unbalanced ...

In this paper we propose the study of a centrifugal pump control system driven by a three-phase induction motor, which is supplied by a PhotoVoltaic PV generator. The system includes solar panel, a DC / DC converter equipped with its MPPT control, a voltage inverter to three-phase Pulse Width Modulation PWM and a centrifugal pump driven by a three phase induction motor. In order to control the ...

The objective of this study was to improve the reliability of the endurance test for the powertrain system of military tracked vehicles. The measurement system that measures the driving duty applied to the powertrain system caused by mobility on roads consists of eight analog channels and two pulse channels, including the propeller shaft output torques for the left and right sides. The data obt...

In order to make a wind power generation truly cost-effective and reliable, an advanced control techniques must be used. In this paper, we develop a new control strategy, using nonlinear model predictive control (NMPC) approach, for DFIG-based wind turbine. The DFIG is fed through the rotor windings by a back-to-back converter controlled by Pulse Width Modulation (PWM), where the stator winding...

To reduce the torque ripple in motors resulting from use of conventional direct control (DTC), a model predictive (MPC)-based DTC strategy for matrix converter-fed induction motor is proposed this paper. Two new look-up tables are proposed, these derived on basis electromagnetic and stator flux using all feasible voltage vectors their associated switching states. Finite set (FCS-MPC) has then b...

Figure 3 Known potential and limitations of driveline optimization (Ref. 2). Management Summary In today’s motor vehicles, an optimally designed driveline provides substantial CO2 reduction. Different transmission systems, such as manual transmissions, torque-converter transmissions, dual-clutch transmissions, CVTs and hybrid systems, work better with different requirements and vehicle classes....

This paper presents the state space modelling of doubly fed induction generator (DFIG) for small signal stability assessment. The gains of PI controller in torque and voltage control loop of rotor-side converter (RSC) are optimized by particle swarm optimization (PSO) to improve the dynamic performance of DFIG. These optimized parameters results in improved damping of DFIG and minimizes the osc...

Simple power electronic drive circuit and fault tolerance of converter are specific advantages of SRM drives, but excessive torque ripple has limited its application. This paper presents a novel method of controlling the motor currents to minimize the torque ripple, using a neuro-fuzzy compensator. In the proposed control concept, a compensating signal is added to the output of a classical PI c...

Speed control of an induction motor requires a 3-phase power supply that can vary both voltage and frequency. Such creates variable-speed rotating field in the stator allows rotor to rotate at required speed with low slip. A static frequency converter efficiently provide full torque from zero speed, overspeed when necessary, easily bidirectional operation by changing phase rotation. Although pr...
