Dynamic Frequency Support from a DFIG-Based Wind Turbine Generator via Virtual Inertia Control

Short-Term Frequency Response of a DFIG-Based Wind Turbine Generator for Rapid Frequency Stabilization

This paper proposes a short-term frequency-response scheme of a doubly-fed induction generator (DFIG)-based wind turbine generator (WTG) for improving rotor speed recovery and frequency nadir. In the energy-releasing period, to improve the frequency nadir and rotor speed convergence by releasing a large amount of kinetic energy stored in the rotating masses in a DFIG-based WTG, the power refere...

Depressing Turbine-Generator Supersynchronous Torsional Torques by Using Virtual Inertia

Single-pole switching scheme is widely used in the Extra High Voltage system. However, the substantial negativesequence current injected to the turbine-generators imposes the electromagnetic (E/M) torque of double systemfrequency components during the dead time (between single-pole clearing and line reclosing). This would induce supersynchronous resonance (SPSR) torque amplifications on low pre...

Protection of DFIG wind turbine using fuzzy logic control

Double Fed Induction Generator; Crowbar protection; ANFIS; Fuzzy logic; Fault current and voltages Abstract In the last 15 years, Double Fed Induction Generator (DFIG) had been widely used as a wind turbine generator, due its various advantages especially low generation cost so it becomes the most important and promising sources of renewable energy. This work focuses on studying of using DFIG a...

Performance of a Doubly Fed Induction Generator (DFIG) Wind Turbine System During System Imbalances

The major concern in smooth operation of the DFIG wind turbine technology is control of wind turbine generators to ensure stable operation and to avoid sympathetic trips during system imbalances. The operation of the DFIG under different disturbances is analyzed using MATLAB Simulink and the built-in model developed by DIgSILENT in their PowerFactory software. The specific imbalances studied ar...
