LVRT Control Strategy of Grid-connected Wind Power System [PDF]

The Transactions of the Korean Institute of Power Electronics, 2011
This paper proposes a LVRT (Low Voltage Ride Through) control strategy which should be satisfied by grid-connected wind power system when grid faults occur. The LVRT regulation indicates rules or actions which have to be executed according to the voltage dip ratio and the fault duration.
