ESO-Based Inertia Emulation and Rotor Speed Recovery Control for DFIGs

IEEE Transactions on Energy Conversion, 2017
In recent years, with the ever increasing penetration of wind generation, great concerns have been raised since the constantly decline of system's inertia may considerably deteriorate the frequency stability of power system. In this regard, an inertial response control technique is proposed to enable wind generators to provide the power system with ...

Inertia Emulation of PMSG-Coupled Wind Turbines with Rotor Speed Recovery Support from DC-link Capacitors

2020 IEEE 9th International Power Electronics and Motion Control Conference (IPEMC2020-ECCE Asia), 2020
The increasing amount of variable speed wind turbines (VSWTs) is witnessed by modern power systems. However, this high-penetration level of wind energies leads to the reduction of power system inertia. To solve the lack of inertia issue, releasing the kinetic energy stored in the rotating masses of Permanent Magnet Synchronous Generator (PMSG)-coupled ...

Fuzzy logic control for speed of wound rotor induction motor with slip energy recovery

SICE '99. Proceedings of the 38th SICE Annual Conference. International Session Papers (IEEE Cat. No.99TH8456), 2003
Fuzzy logic control is considered for speed of wound rotor induction motors with slip energy recovery. The speed is limited at some range of sub-synchronous speed of the rotating magnetic field. By controlling speed by adjusting the resistance value in the rotor circuit the efficiency of power is reduced, because of the slip energy lost when it passes ...

Adaptive fuzzy-neuro controller for speed of wound rotor induction motor with slip energy recovery

2000 TENCON Proceedings. Intelligent Systems and Technologies for the New Millennium (Cat. No.00CH37119), 2002
In this paper, the authors proposed an adaptive fuzzy-neuro controller to control the speed of a wound rotor induction motor with slip energy recovery. An adaptive fuzzy-neuro controller has been designed by integrating two neural network models with a basic fuzzy logic controller.

Theoretical investigations on rotor speed of the self-driven rotary energy recovery device through CFD simulation

Desalination, 2016
Abstract The theory about how to calculate the rotor speed for a self-driven rotary energy recovery device has been investigated by methods of computational fluid dynamics simulation and validating experiments in this paper. Rotor speed can be obtained according to impulse torque of the rotor and its frictional resistance.

Two improved control strategies for rotor speed protection and recovery in the frequency support process of grid-forming wind turbines

Journal of Renewable and Sustainable Energy
Traditional grid-following virtual inertia control wind turbines (WTs) typically achieve rotor speed protection (RSP) and recovery (RSR) through adjusting coefficients. However, for grid-forming (GFM) virtual synchronous generator (VSG) controlled WTs, due to the coupling between parameters and damping characteristics, the adjustment range is limited ...
