Abstract— This paper presents the modeling and control back stepping of Double-Fed Induction Generator (DFIG) integrated into a wind energy system. The goal is to apply this technique to control independently the active and reactive power generated by DFIG. Finally, the system performance was tested and compared by simulation in terms of following instructions and robustness with respect to par...

The Brushless Doubly-Fed Reluctance Generator (BDFRG) is a potential alternative to the Doubly Fed Induction (DFIG) in wind power applications owing its reasonable cost, competitive performance, and high reliability. In comparison with (BDFIG), BDFRG more efficient easier control cage-less rotor. One of most preferable advantages over DFIG inherently better performance under unbalanced grid con...

In this paper, DQ-modeling approach for Transient State analysis in the time domain of the threephase self-excited induction generator (SEIG) with squirrel cage rotor is presented along with its operating performance evaluations. The three-phase SEIG is driven by a variable-speed prime mover (VSPM) such as a wind turbine for the clean alternative renewable energy in rural areas. Here the prime ...

The non conventional sources are important now days because the raw material required is less and power demand is more to compensate with the increasing demand of power, so renewable energy sources are important Micro grid which resembles a power system consisting of several distributed generators connected together and this micro grid operates in connecting mode which is connected to the main ...

Brushless Doubly-Fed Machine has attracted considerable attention in recent years due to its advantages. It has the robustness of the squirrel cage induction machine, and the speed and power factor controllability of the synchronous machine as well as the absence of brushes and slip rings, and using a fractionally rated frequency converter. Hence, there are considerable benefits over the conven...

Abstract When fault occurs in high wind power proportion grid, the control strategy and external characteristics of plant are affected by voltage drop so traditional short-circuit current engineering calculation is difficult to converge. A method for considering grid node importance evaluation crowbar protection DFIG(double-fed induction generator), proposed. This paper proposes equivalent mode...

In this paper the Space Vector Control Scheme is implemented for a Wind Energy System using Three Level Impedance Source Inverter (ZSI). The wind energy system uses a Self Excited Induction generator (SEIG) which is the most emerging application in the field of Wind Energy Conversion System (WECS). The proposed system is modelled with a generator-side Diode Bridge Rectifier and a Stand-Alone si...

Micro-hydro generator schemes are an attractive choice for electricity generation in remote locations or underdeveloped communities where a grid supply is not available. Since such systems must be low cost, reliable, and robust to minimise maintenance requirements, the use of a standard squirrel cage induction motor is appealing – either three phase or single phase depending on power ratings an...
