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.

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 ...

Mitigation of harmonics of DFIGs in DC-microgrids
2012 IEEE Energy Conversion Congress and Exposition (ECCE), 2012During the last few years, there has been an increased attention paid on the developments of DC microgrids (DCMGs) and their applications. For economical and more flexible wind power generation, doubly fed induction generator (DFIG) is regarded as a most commonly used generator in wind farms. This paper presents a configuration and operation method for

Stagewise control of connecting DFIG to the grid
2006 IEEE International Symposium on Industrial Electronics, 2006In order to compensate initial error of position encoder used for ac excited DFIG (Doubly Fed Induction Generator), a controller was proposed based on the steady state relationship between rotor currents and stator voltages with open stator windings, which is derived according to the mathematical model of DFIG in the synchronous frame. The compensation

A Technical Review on LVRT of DFIG Systems
2016The most important issue with doubly fed induction generator (DFIG) wind turbine is low voltage ride-through performance. To solve this problem, several techniques have been introduced. The paper discusses some of the most commonly used solutions for Low Voltage Ride Through (LVRT) of wind turbine generators which is the most important feature to be ...
