Efficient Low-Voltage Ride-Through Nonlinear Backstepping Control Strategy for PMSG-Based Wind Turbine During the Grid Faults

M. Nasiri; J. Milimonfared; S. H. Fathi

Volume 6, Issue 2 , December 2018, , Pages 218-228


  This paper presents a new nonlinear backstepping controller for a direct-driven permanent magnet synchronous generator-based wind turbine, which is connected to the power system via back-to-back converters. The proposed controller deals with maximum power point tracking (MPPT) in normal condition and ...  Read More

A Novel Algorithm for Rotor Speed Estimation of DFIGs Using Machine Active Power based MRAS Observer

R. Ajabi-Farshbaf; M. R. Azizian; V. Yousefizad

Volume 6, Issue 1 , June 2018, , Pages 61-68


  This paper presents a new algorithm based on Model Reference Adaptive System (MRAS) and its stability analysis for sensorless control of Doubly-Fed Induction Generators (DFIGs). The reference and adjustable models of the suggested observer are based on the active power of the machine. A hysteresis block ...  Read More

Low Voltage Ride Through Enhancement Based on Improved Direct Power Control of DFIG under Unbalanced and Harmonically Distorted Grid Voltage

Ahmadreza Nafar; Gholam Reza Arab Markadeh; Amir Elahi; Reza pouraghababa

Volume 4, Issue 1 , June 2016, , Pages 16-28

  In the conventional structure of the wind turbines along with the doubly-fed induction generator (DFIG), the stator is directly connected to the power grid. Therefore, voltage changes in the grid result in severe transient conditions in the stator and rotor. In cases where the changes are severe, the ...  Read More
