Huawei SUN2000-90KTL Series User Manual

Parameter Description
Communication disconnection
fail-safe
In the inverter export limitation scenario, if this parameter is
set to Enable, the inverter will perform active power derating
by percentage when the communication between the
inverter and the SmartLogger or Smart Dongle is
disconnected for more than the time specied by
Communication disconnection detection time.
Communication disconnection
detection time (s)
Species the fail-safe detection time for the disconnection
between the inverter and the SmartLogger or Smart Dongle.
Active power output limit for fail-
safe (%)
Species the derating value of the inverter active power by
percentage.
Underfrequency rise power The standards of certain countries and regions require that if
the power grid frequency is lower than Frequency for
triggering of underfrequency rise power, the inverter
needs to increase the active power output to help increase
the power grid frequency. In this case, set this parameter to
Enable.
Frequency for triggering of
underfrequency rise power (Hz)
Species the frequency threshold of Underfrequency rise
power.
This parameter is displayed when Underfrequency rise
power is set to Enable.
Power recovery gradient of
underfrequency rise (%/min)
Species the recovery rate of Underfrequency rise power.
This parameter is displayed when Underfrequency rise
power is set to Enable.
Cuto frequency of
underfrequency rise power (Hz)
Species the cuto frequency of Underfrequency rise
power.
This parameter is displayed when Underfrequency rise
power is set to Enable.
Cuto power of underfrequency
rise power (%)
Species the cuto power of Underfrequency rise power.
This parameter is displayed when Underfrequency rise
power is set to Enable.
Frequency for exiting of
underfrequency rise power (Hz)
Species the exit frequency of Underfrequency rise power.
This parameter is displayed when Underfrequency rise
power is set to Enable.
Q-U characteristic curve mode Species the reactive power compensation mode of the
inverter output.
Power percentage for triggering
Q-U scheduling
Species the reference apparent power, in percentage. When
the actual apparent power of the inverter is greater than the
value of this parameter, the Q-U characteristic curve
scheduling function is enabled.
