Loss of Excitation Detection in Doubly Fed Induction Generator by Voltage and Reactive Power Rate
The doubly fed induction generator (DFIG) is one of the most popular technologies used in wind power systems. With the growing use of DFIGs and increasing power system dependence on them in recent years, protecting of these generators against internal faults is more considered. Loss of excitation (LOE) event is among the most frequent failures in electric generators. However, LOE detection stud...

متن کاملSliding-Mode-based Improved Direct Active and Reactive Power Control of Doubly Fed Induction Generator under Unbalanced Grid Voltage Condition
This paper proposes an improved direct active and reactive power control (DPC) strategy for a grid-connected doubly fed induction generator (DFIG) based wind-turbine system under unbalanced grid voltage condition. The method produces required rotor voltage references based on the sliding mode control (SMC) approach in stationary reference frame, without the requirement of synchronous coordinate...
متن کاملReview on Wind Power Generation With Doubly Fed Induction Generator
This paper presents the review of the Doubly fed Induction Generator (DFIG) based Wind Energy Conversion System (WECS). Basically the various challenges of the grid connected DFIG based wind turbine has been highlighted in this review. Nonlinear model of wind turbine with DFIG configuration are explained and a 1.2 MW, 50 Hz, 6 pole DFIG simulated using MATLAB/SIMULINK. Some important control is...
متن کاملOptimal 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...
