Behavior Analysis of the DFIG Wind Turbine in Voltage Double-Dip

Abstract:

At present, the research on wind turbine low voltage ride through (LVRT) behavior is one of hotspots in wind power industry. With increasing share of wind power in the grid, it is important to enhance the LVRT performance of wind turbines to guarantee the safety and reliability of the grid. The phenomenon of voltage double-dip is one of cases during the voltage dips. In this paper, the voltage double-dip phenomenon is described, and the stator flux attenuation of DFIG wind turbine in the voltage dip is analyzed. The results show that when the second voltage dip occurs, the initial value of the stator flux should be considered. Finally, by on-site testing results, the impact of voltage double-dip to the wind turbine is verified, if the initial value of the stator flux is not considered, and the interval of two voltage dips is different.
