The recently stipulated grid codes require wind generators to re-initiate normal power production after voltage sag. This paper presents a comparative performance of two commonly employed variable speed turbines in today’s electricity market, the doubly fed induction generator (DFIG) and permanent magnet synchronous (PMSG) turbines. evaluation both was performed for weak, strong grids, consider...

The effect of wind generator on sub-synchronous resonance (SSR) is being interested by increasing penetration of wind turbine in power systems,. Purpose of this article is to analyze SSR in a wind farm based on doubly fed induction generator (DFIG) which is connected to compensating series grid. A dynamic model for analysis of induction generator effect and Torsional Interaction (TI) has been u...

This paper presents a robust control of Doubly Fed Induction Generator (DFIG) wind turbine in a sample power system. DFIG consists of a common induction generator with slip ring and a partial scale power electronic converter. Indirect fieldoriented controller is applied to rotor side converter for active power control and voltage regulation of wind turbine. On grid side PQ control scheme is app...

With the gradual integration of large wind farms, power penetration in system is gradually increasing. Since different turbines access grid may have effects on system, it necessary to study effect transient stability. This paper makes a comparative stability constant speed turbine (CSWT) and doubly-fed induction generator (DFIG) after grid-connected. Firstly, we present dynamic models CSWT DFIG...

For the first time, a novel concept of merging computational intelligence (the type-2 fuzzy system) and control theory (optimal control) for regulator reference tracking in doubly fed induction generators (DFIGs) is proposed this study. The goal system torque stator reactive power. In case, controller activated to enhance performance optimum control. instance, abrupt changes signal or uncertain...
