Huawei SmartLogger3000 User Manual

Parameter Description Remarks
Power raising
caused by
underfrequency
The standards of certain countries and regions
require that when the power grid frequency is lower
than Trigger frequency of underfrequency rise
power, the device needs to increase the active
power output to help increase the power grid
frequency. In this case, set this parameter to Enable.
-
Recovery
gradient of
underfrequency
rise power (%/
min)
Species the power recovery rate of
underfrequency-caused raising.
This parameter is
displayed when the
Power raising caused
by underfrequency is
set to Enable.
Cuto power of
underfrequency
rise power (Hz)
Species the frequency threshold for stopping
underfrequency-caused raising.
Cuto power of
underfrequency
rise power (%)
Species the cuto power of the power raising
caused by underfrequency.
Trigger
frequency of
underfrequency
rise power (Hz)
Species the frequency threshold for
underfrequency-caused power raising.
Quit frequency
of
underfrequency
rise power (Hz)
Species the quit frequency of the power raising
caused by underfrequency.
O&M via USB
connection
Species the USB O&M port status: Permanently
Enabled, Disabled in Idle State, or Permanently
Disabled.
-
USB wakeup Used to remotely wake up the USB O&M port. After
being idle for 4 hours, the port is automatically
disabled.
-
Quick startup
for short-time
grid
disconnection
The default value is Disable. Species whether to
allow the device to quickly start after the power
grid recovers from a short-time failure.
-
Microgrid
compatibility
The default value is Disable. If the PCS and diesel
generator run in parallel and the PCS works in PQ
mode, set this parameter to Enable. When
Microgrid compatibility is set to Enable, the grid-
connected current source PCS supports a higher
ratio of PV to energy storage in addition to the
feature of the original country grid code.
If this parameter is set
incorrectly, the Smart
PCS may run abnormally.
