Abstract
Wind turbine driven doubly-fed induction generators (DFIGs) are widely used in the wind power industry. With the increasing penetration of wind farms, analysis of their effect on power systems has become a critical requirement. This paper presents the modeling of wind turbine driven DFIGs using the conventional vector controls in a detailed model of a DFIG that represents power electronics (PE) converters with device level models and proposes an average model eliminating the PE converters. The PSCAD/EMTDC™ (4.6) electromagnetic transient simulation software is used to develop the detailed and the proposing average model of a DFIG. The comparison of the two models reveals that the designed average DFIG model is adequate for simulating and analyzing most of the transient conditions.

Summary
With the improvements of wind power generation technology and associated cost reductions, the global installed wind capacity has grown at a rapid rate during the last decade [1]. 1726converters are modeled with device level details, in PSCAD/EMTDC is presented in [6] It describes the simulation models of the machine, wind turbine and PE converter controls in detail, and presents performance of the developed DFIG simulation model when connected to a where radial. When the detailed to address this, an average model of a DFIG driven by a wind turbine is presented in [8]. Different simplified swing stability of synchronous generators using the simplified DFIG model, but its accuracy is not transient model of a DFIG is used in [9] to study the inertia characteristics of a DFIG wind turbine validated. This paper addresses of details of modeling wind turbine-driven for EMT stability of synchronous generators using the simplified model, but its accuracy is not validated.
