Technology developments related to the renewable energy industry are increasing, one example of wind power generation technology which has several relationship configurations with generator. This system configuration is known a generator DFIG (Double Fed Induction Generator). can supply active from induction stator connected directly network while rotor through back converter. The operation dou...

As one of the most promising Distributed Generation (DG) sources, wind power technology has been widely developed in recent years. Doubly fed induction generator (DFIG) is currently employed as one of the most common topologies for wind turbine generators (WTGs). This generator operates as a synchronous/asynchronous hybrid generators. Therefore, it is necessary to power engineers find understan...

We developed an analog very large-scale integrated system of two mutually inhibitory silicon neurons that display several different stable oscillations. For example, oscillations can be synchronous with weak inhibitory coupling and alternating with relatively strong inhibitory coupling. All oscillations observed experimentally were predicted by bifurcation analysis of a corresponding mathematic...

in this paper optimal torque control (otc) of stand-alone variable-speed small-scale wind turbine equipped with a permanent magnet synchronous generator and a switch- mode rectifier is presented. it is shown that with otc method in standalone configuration, power coefficient could be reached to its maximum possible value, i.e. 0.48. an appropriate control algorithm based on turbine characterist...

This paper proposes a parallel-resonance bridge type fault current limiter (PRBFCL) to augment the transient stability of a hybrid power system consisting of a photovoltaic (PV) power generation source, a doubly-fed induction generator (DFIG)-based wind energy system, and a synchronous generator (SG). The PRBFCL is designed such a way that it can provide sufficient damping characteristics to th...

This paper presents robust controller design for a wind-driven induction generator system using structured singular value ( -synthesis) method. The controller was designed for a static synchronous compensator (STATCOM) and a variable blade pitch angle in a wind energy conversion system (WECS) in order to achieve the required voltage and mechanical power control. The results indicated that this ...

This paper focuses on the turbine-generator shaft models of double-cage Induction Generator (IG) based wind farm and its influence on the sub-synchronous resonance phenomenon. For this purpose, six different shaft models as 6-mass, 4-mass, 3-mass I, 3-mass II, 2-mass and 1-mass models are considered for double-cage IG wind-turbine. By using the linear modal analysis method, the effects of the d...
