Transient torque reversals in indirect drive wind turbines

The resulting opposing torque is measured at the low-speed shaft and used in place of the opposing generator torque. The SIMPACK model, at the rotor end, accepts the three-dimensional rotor torques/moments and

Bode plot of the transfer function between the generator speed and wind

It can be concluded that the generator speed lags the wind turbine torque by 450° at 3p frequency f 3p, when the fluctuation of the electromagnetic torque of the generator is controlled to zero

Wind turbine per unit torque versus speed characteristic

The load torque is developed by the induction generator and it is estimated via the asymptotic observer (3), and changes from 0.12 to 0.81 N · m approximately, with an overshoot of 29%,

Difference between nominal speed and idle RPM of a DC generator

To my understanding the nominal speed of the generator denotes the speed needed to match the power supply frequency (e.g. 50 Hz in Austria), if the generator is supposed to feed back into

6 FAQs about [Wind Jun 5 generator idler torque]

Does torque ripple reduce a wind turbine generator?

Auswirkung der Optimierung der Drehmomentwelligkeit des Generators auf den Antriebsstrang einer Windkraftanlage mit Getriebe In this paper, the load effect of torque ripple reduction of a wind turbine generator is analyzed on the high-speed shaft gear stage and high-speed shaft bearings, which are the nearest components to the generator.

Can NREL 5MW reference wind turbines have different torque ripples?

Two generator designs with different torque ripples for the NREL 5‑MW reference wind turbine are considered. A decoupled analysis method is used, where global loads and torque ripple loads are used as input to a multibody model of the drivetrain in order to analyze the gear and bearing load response.

Do wind turbine rotors stall in idling operation mode?

This work is distributed under the Creative Commons Attribution 3.0 License. Abstract. Wind turbine rotors in idling operation mode can experience high angles of attack within the post-stall region that are capable of triggering stall-induced vibrations.

Is there a generic controller for NREL 5 MW wind turbines?

The updated generic controller has also been tested and evaluated on the DTU 10-MW [5, 6] wind turbine with similar results. Additional testing of the automatic tuning on turbines other than the NREL 5-MW and DTU 10-MW wind turbines is necessary to further validate this “generic” controller.

How do NREL 5MW generator torque controllers work?

In the legacy NREL 5-MW controller, the generator torque in Region 2.5 is defined by a simple linear interpolation between an operating point in Region 2 and the beginning of Region 3. This, along with some basic switching logic, prevents the blade pitch and generator torque controllers from conflicting. 3. Generic controller overview

How do you calculate generator torque?

The generator torque is defined by τg = τg ,r (3) = , ωg r , for constant torque operation. In (3), τg ,r, Pr, and ωg ,r are the rated generator torque, power, and generator speed, respectively. The blade pitch controller is a PI, gain-scheduled controller that collectively pitches the blades to maintain generator speed.
