A real wind turbine works, in steady-state, at the maximum point of the curve power-speed, due to the MPPT algorithm operation, and thus a speed increase would lead to a smaller power and torque.…”

“…The decoupling introduced by the dc-link in the back-to-back configuration makes easier to analyze separately the generator-and grid-side converters. Therefore, many contributions are focused in only one side of the topology [15], [22]- [25]. However, the predictive control applied to the complete back-to-back NPC-based WECS is hardly covered by the current literature in the field [26].…”

Abstract-As wind power technology points to increase power ratings, the implementation based on a permanent-magnet synchronous generator with a full power converter is expanding its market share. Multilevel converters, as for example, neutralpoint clamped converters, are therefore well suited for this application. Predictive current control presents similar dynamic response and reference tracking than other well-established control methods, but working at lower switching frequencies, and providing extensive flexibility to apply either on-line or off-line different control laws to the same plant. In this work, the predictive current control is applied to the both sides of the backto-back neutral-point clamped converter connecting a permanent-magnet synchronous wind power generator to the grid. Dc-link neutral-point balance is achieved by means of the predictive control algorithm, which considers the redundant switching states of the back-to-back neutral-point clamped converter. Reduced number of commutations, current spectrum control, and compliance with the low voltage ride-through requirement are carried out with the predictive control. The obtained experimental results confirm the suitability of the proposed control approach.

A simple and efficient position sensorless control method based on feedforward voltage estimation for PMSG improved with multi-parameter estimation using MRAS is proposed in this paper. The dynamically enhanced stator feedforward dq-axes voltages that are derived from steady-state PMSG model are modified for the sensorless drive. In direct-drive wind turbine systems, because of low back-EMF amplitude in the generator output at very low speed operation, the rotor flux linkage cannot be predicted correctly. Vector control is often used in PMSG control, because it has a simple structure and is suitable for various industrial systems. In the power equation, maximum power is obtained as a function of torque and speed. In the proposed method, a variable-speed wind turbine system with back to back converter structure is connected to common DC-link. In this paper, the proposed sensorless control scheme has been implemented with 1 kW PMSG drive controlled by a TMS320F28335 DSP for low speed at 0.1 p.u. (300 rpm) is achieved under multi-parameter variations. Keywords

SUMMARYA rotor speed estimation algorithm in a direct vector controlled permanent magnet synchronous generator wind energy conversion system is proposed. The proposed method is based on a simple equation obtained from the flux model of the machine and contains only stator flux and current. Constant gain recursive least squares estimator is used for implementing the speed estimation algorithm. Rotor position information used for coordinate transformation is computed using the estimated speed. Stator flux information required by the speed estimator is obtained using the stator voltage equation by implementing a programmable low pass filter. The estimated speed is used as the feedback signal for the speed control loop of the vector controlled machine side converter control system whose command speed is obtained from a wind speed sensorless maximum power point tracking controller, thus, we obtain a complete rotor speed and wind speed sensorless permanent magnet synchronous generator wind energy conversion system. Simulation is carried out to validate the performance of the proposed method. Copyright © 2012 John Wiley & Sons, Ltd.
