Abstract


In order to study the across characteristics of DFIG under the voltage fault conditions, using a wind power system simulation model consist of six 1.5MW doubly-fed wind turbines. Take a simulation analysis on the power change caused by the voltage and current fluctuation of each node of the grid and wind farm under four failure conditions, which including wind speed mutate, grid voltage sag, single-phase ground fault, three-phase short circuit fault. Analyze transient characteristics of DFIG system when voltage dropped. Reveal the operating state and change rule of DFIG working on these four failure conditions as above.
