In the new electricity grid code, reactive power generation by wind farms, which must operate similarly to other conventional power plants, is a major concern during both steady-state and fault conditions. This article presents the reactive power capability of a doubly-fed induction generator (DFIG) through the use of performance capability curves. The real and reactive power capability of conv...

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...
