Figure 66: 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.
The operation for FRT(Fault Ride Through) control is possible to set by parameter as follows.
