Method of DFIG Cooperating with SVG to Suppress Low-Frequency Oscillation in Power Systems
Zhongguo dianli, 2020 With the increasing penetration of wind power, when the power system is insufficiently damped, low-frequency oscillations are likely to occur. Doubly fed induction generation (DFIG) can decouple the control of active and reactive power, which helps ...

Fast Coordinated Control of DFIG Wind Turbine Generators for Low and High Voltage Ride-Through [PDF]
, 2014 This paper presents a fast coordinated control scheme of the rotor side converter (RSC), the Direct Current (DC) chopper and the grid side converter (GSC) of doubly fed induction generator (DFIG) wind turbine generators (WTGs) to improve the low voltage ...

Backstepping approach applied to the DFIG-WECS [PDF]
International Meeting on Advanced Technologies in Energy and Electrical Engineering, 2020 The growing need for energy in the world and the depletion of classical energy resources (fuels) have led researchers to develop new means of producing abundant and inexhaustible energies called “renewable energies”. In this context, we propose the study of a Wind Energy Conversion System (WECS) driven by a Doubly Fed Induction Generator (DFIG).

Lyapunov-Based Robust Power Controllers for a Doubly Fed Induction Generator
Iranian Journal of Electrical and Electronic Engineering, 2020 In this work, a robust nonlinear control technique of a doubly fed induction generator (DFIG) intended for wind energy systems has been proposed. The principal idea in this article is to decouple the active and reactive power of the DFIG with high ...

Wind Energy, EarlyView.ABSTRACT The installed wind energy capacity increases every year. However, operation and maintenance costs still make up a considerable portion of the levelized costs of electricity. This costs can be greatly reduced by the application of suitable early fault detection methods. The supervisory control and data acquisition system of wind turbines is one

IOP Conference Series: Materials Science and Engineering, 2017 Sub-synchronous resonance (SSR) occurred in the power system with both Doubly Fed Induction Generators (DFIGs) and series-compensated lines. There have been several papers focusing on the analysis of such SSR phenomenon. To the authors' knowledge, the impacts of DFIG numbers are seldom considered in existing papers.

Techno-economic comparison of operational aspects for direct drive and gearbox-driven wind turbines [PDF]
, 2010 The majority of wind turbines currently in operation have the conventional Danish concept design-that is, the three-bladed rotor of such turbines is indirectly coupled with an electrical generator via a gearbox.
