Optimal Operation of Doubly-fed Induction Generator used in a Grid-Connected Wind Power System

In this paper, a wind power system based on a doubly-fed induction generator (DFIG) is modeled and simulated. To guarantee high-performance control of the powers injected into the grid by the wind turbine, five intelligent super-twisting sliding mode controllers (STSMC) are used to eliminate the active power and current ripples of the DFIG. The STSMC controller is a high-order sliding mode cont...

Transient Behavior of Doubly Fed Induction Generator Using Simulink Model in Wind Energy Conversion System

In this paper, transient behaviours of the Doubly Fed Induction Generator using Simulink model is demonstrated. A mathematical model based on d-q transformation i.e. stator phase currents, rotor currents, stator flux linkages,rotor flux linkages ,instantaneous power electromagnetic torque is also presented. In this paper 9 MW wind farm consisting of six 1.5 MW wind turbines connected to a 25 kV...

Performance Analysis of Doubly- Fed Induction Generator for Wind Energy Conversion System

This paper presents voltage fed current regulated rotor-side and grid-side control of doubly-fed induction generator (DFIG) under steady and transient conditions. The vector control of grid-side is made to control the active and reactive power flow from the utility grid to the grid side converter independently and also maintain the dc-link voltage constant. Machine-side control regulates the sp...
