چکیده

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 crowbar protection and new protection method ,named the outer crowbar protection. Operation and dynamic behavior of the outer crowbar protection with the DFIG during grid fault will be illustrated in this paper.

Fault Behavior of Wind Turbines

Synchronous generators have always been the dominant generation type in the grid. This fact affected both planning and operation of power systems. With the fast increase of wind power share in the grid in the last decade, the situation is changing. In some countries wind power represents already a consistent amount of the total generation. Wind turbines can be classified as non-synchronous gene...

Behavior of DFIG Wind Turbines with Crowbar Protection under Short Circuit

Doubly Fed Induction Generators DFIG are nowadays widely used in variable speed wind power plants. The dynamic interaction between variable speed DFIG wind turbines and the power system which is subjected to disturbances, such as short circuit faults, is an important issue. The ability of the wind power plant to stay connected to the grid during disturbances is important to avoid a cascading ef...
