Parameters
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.
• Grid Under Voltage Levels
- Grid Under Voltage Level 1 – Transfer to FRT mode.
- Grid Under Voltage Level 2 – Inverter stops its operation with ‘Grid Under Voltage Level 2 Fault’ when the
grid voltage below ‘Grid Under Voltage Level 2’ sustains over “Grid Under Voltage Trip Time 2”.
- Grid Under Voltage Trip Time 1 – Permissible grid voltage under ‘Grid under Voltage Level 1’ time.
- Grid Under Voltage Trip Time 2 – Permissible grid voltage under ‘Grid Under Voltage Level 2’ time.
