Large Disturbance Stability Analysis of Wind Turbine Implemented with DFIG

Authors

Abstract:

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 understand the characteristics of the DFIG better. This paper presents an analytical method for analysis of large-disturbance stability of DFIG. The proposed method is based on the concepts of stable and unstable electrical-mechanical equilibrium points, the electrical-mechanical torque versus rotor speed and Critical fault clearance time of DFIG. The results of analysis specify the effective parameters on the large-disturbance stability of DFIG too. By using this method ones can reduce the simulation efforts necessary to assess the large-disturbance stability of DFIG.

Control and Simulation of a Crowbar Protection for DFIG Wind Turbine during Power Systems Disturbance

The use of the doubly fed induction generator (DFIG) in modern variable-speed wind turbines has increased rapidly. According to the new grid code requirements, wind turbines generators must remainconnected to the grid during grid disturbances so crowbar protections systems is being used to protect the DFIG, this paper introduces a comparison between conventional crowbar protection, series crowb...

Stability Analysis of DFIG based Wind Energy System

This paper presents system stability analysis of DFIG based wind energy conversion system. Presently for variable wind speed DFIG is considered as efficient machine to generate the power. In addition to this advanced AC/DC/AC converters with closed loop control system has been presented. For stability analysis 1.5MW wind turbine has been considered. As the speed of the wind varies by ± 18% to 2...

Behavior of DFIG Wind Turbine during Unbalanced Grid Voltage

The use of doubly fed induction generators (DFIGs) in wind turbines has become quite common for the last few years. These machines provide variable speed and are driven with a power converter which is sized for a small percentage of the turbine-rated power. This paper presents a detailed model of an induction generator coupled to wind turbine system. Modeling and simulation of the induction mac...
