High Voltage Ride Through Strategy For DFIG Considering HVDC System Converter Blocking

, 2019
This paper presents a P-Q coordination based high voltage ride through (HVRT) control strategy for double fed induction generators (DFIGs) based on a combined Q-V control and P-V de-loading control. The active/reactive power injection effect of DFIG on transient overvoltage is firstly analyzed and the reactive power capacity evaluation of DFIG ...
