Enhancement of Reactive Power Capability of DFIG using Grid Side Converter
نویسندگان
چکیده
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 conventional DFIG, the Unified Architecture (UA) is analyzed for various firing angles and modulation indexes (μ) of the grid side converters (GSC).The performance of both the DFIG models are compared and the enhanced reactive power capability is illustrated. The simulation is carried out in simulink based MATLAB environment.

In the conventional structure of the wind turbines along with the doubly-fed induction generator (DFIG), the stator is directly connected to the power grid. Therefore, voltage changes in the grid result in severe transient conditions in the stator and rotor. In cases where the changes are severe, the generator will be disconnected from the grid and consequently the grid stability will be attenu...
