2023年5月13日 The large-scale wind energy conversion system (WECS) based on a doubly fed induction generator (DFIG) has gained popularity in recent years because of its various economic and technical merits.
The turbine model uses the Wind Turbine bloc of the Renewables/Wind Generation library. See documentation of this model for more details. Induction Generator. The doubly-fed induction generator phasor model is the same as the wound rotor asynchronous machine (see the Machines library) with the following two points of difference:
3 天之前 The doubly-fed induction generator (DFIG) system is a popular system in which the power electronic interface controls the rotor currents to achieve the variable speed necessary for maximum energy capture in variable winds. Because the power electronics only process the rotor power, typically less than 25% of the overall output power, the
2023年7月16日 A Doubly Fed Induction Generator has a stator winding directly coupled with grid whereas rotor is to the grid via a fault-prone converter. In early times, when a fault occurred, these generators were required to disengage from the grid.

A new rotor active power feedback, under the cascade regulation superordinated both to the DFIG rotor current internal feedback and the DFIG stator power external feedback has been introduced. The
2023年12月27日 As wind turbine generator systems become more common in the modern power grid, the question of how to adequately protect them from cyber criminals has become a major theme in the development of new control systems. As such, artificial intelligence (AI) and machine learning (ML) algorithms have become major contributors to preventing,
2015年4月24日 This paper focuses on the electro-thermal analysis of a doubly-fed induction generator (DFIG) in a wind turbine (WT) with gear transmission configuration. The study of the thermal mechanism plays an important role in the development of cost-effective fault diagnostic techniques, design for reliability and premature failure prevention.
The increase in wind power penetration, at 456 GW as of June 2016, has resulted in more stringent grid codes which specify that the wind energy conversion systems (WECS) must remain connected to the system during and after a grid fault and, furthermore, must offer grid support by providing reactive currents. The doubly fed induction generator (DFIG) WECS
2022年8月22日 Employment of doubly fed induction generator (DFIG) in large variable-speed wind energy systems, as well as in stand-alone applications, is because of its ability to provide reactive power during grid faults and voltage support in low voltage conditions (Cardenas et al. 2013; Ren21 R 2016; Ahmed et al. 2020).
