Figure 61: Grid Voltage 60% Drop

The above graphs show the change of electrical values during FRT (Fault Ride Through) control, and the detailed
description for each section is as follows.

Section 1

If Grid Voltage drops below standard FRT value (0.9

P.U

) set by parameter, inverter will convert its mode to

FRT.

The occurrence of Over Current is decided by the slope and depth, and if when over current occurs, inverter
will stop PWM Modulation for one cycle.

Inverter will infuse the reactive power to grid according to parameter setting.

Since the reactive power value is proportional to the parameter setting value, you can infuse reactive power
to grid as much as possible.

Section 2

Infuse active power and reactive power to grid according to parameter setting.

Section 3

The occurrence of Over Current is decided by the slope and depth, and if when over current occurs, inverter
will stop PWM Modulation for one cycle.

Infuse active power and reactive power to grid according to parameter setting.

Section 4

• If Grid voltage rises above standard FRT value (0.9

P.U

) set by parameter, inverter will convert its mode to

normal and stop reactive current infusion.
