Description
Refers to a control
module that injects step
reactive power to
promote frequency offset
when the offset deviation
of grid voltage and
frequency is very small.
When islanding occurs,
the inverter and load
reaches balance.
Specifies level-1 gain of
the frequency feedback
module.
Specifies level-2 gain of
the frequency feedback
module.
Specifies how the
inverter restarts after a
grid fault is rectified.
Specifies the delay
before restart after a grid
fault is rectified.
Specifies the duration for
the power to gradually
increase when the
inverter starts.
The Japanese standard
requires that the inverter
should control the active
power and reactive
power when the output
voltage exceeds a certain
value to ensure the grid
voltage stability.
The Japanese standard
requires that the inverter
should adjust the reactive
power to prevent the grid
voltage from rising when
the output voltage
exceeds a certain value.
