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 and locations are seldom considered in existing papers.

Review on Grid Connection Technologies of DFIG
Advanced Materials Research, 2012Doubly fed induction generator (DFIG) is receiving more attention nowadays due to growing power demand and environmental concerns. In this paper, five main issues of the DFIG associating with the grid-connection, low voltage ride-through (LVRT), maximum power point tracking (MPPT) control strategy, operation in unbalanced voltage condition ...

DFIG Soft-Sensor and its Applications
2012 Second International Conference on Instrumentation, Measurement, Computer, Communication and Control, 2012The rotor speed measurement of doubly fed induction generator (DFIG) is very important to its control system design, but many problems may arise when applying traditional speed sensor. So, it is necessary to study the speed-sensorless measuring technique.

An Improved HVRT Control Strategy for DFIG
2020 IEEE/IAS Industrial and Commercial Power System Asia (I&CPS Asia), 2020This paper studies the high voltage ride through (HVRT) technology of the doubly fed induction generator (DFIG). Presently, traditional vector control strategies based on stator flux orientation (SFO) for rotor-side converter (RSC) always ignore the dynamic variation process of stator magnetizing current.

Study on Transient Characteristic of the DFIG LVRT
Advanced Materials Research, 2013In order to analyze the operational capability of the low voltage ride through ( LVRT) of a gird-connected wind turbine with doubly fed induction generator (DFIG) effectively, it is necessary to evaluate operation characteristics of DFIG under a grid fault.By using the transient principle of the flux of stator and rotor, the expressions of transient ...
