Fast and accurate voltage sag detection algorithm
Voltage sags may affect the accurate operation of several equipment connected to power systems. A typical example is the doubly-fed induction generator (DFIG), which is often employed in wind energy conversion systems (WECSs). Since the stator windings are directly connected to the power grid, the generator becomes very sensitive to such power quality ...
