Huawei SmartLogger3000 User Manual

Parameter Description Remarks
Working mode The default value is PQ. You need to set the
working mode during deployment. Set Working
mode to VSG in o-grid scenarios and PQ in grid-
tied scenarios.
After this parameter is
set, the device shuts
down.
Per unit
armature
resistance
The default value is 2. Species the resistance per
unit value for armature windings of the virtual
synchronous generator.
This parameter is
displayed when
Working mode is set to
VSG.
NOTE
This parameter must be
set by professional
personnel. Improper
settings may cause device
exceptions.
Per unit
armature
inductive
reactance
The default value is 1. Species the inductive
reactance per unit value for armature windings of
the virtual synchronous generator.
VSG inertia
time constant
The default value is 1. Species the time required
for the virtual rotor of the virtual synchronous
generator to reach the rated speed from the static
state under the rated torque.
P-F adjustment
coecient
The default value is 1. Species the frequency
deviation corresponding to the rated active power of
the virtual synchronous generator.
Q-V adjustment
coecient
The default value is 3. Species the voltage
deviation corresponding to the rated reactive power
of the virtual synchronous generator.
P-V adjustment
coecient
The default value is 0. Species the voltage
deviation corresponding to the rated active power of
the virtual synchronous generator.
Q-F adjustment
coecient
The default value is 0. Species the frequency
deviation corresponding to the rated reactive power
of the virtual synchronous generator.
VSG output
voltage
correction
coecient
The default value is 100. Corrects the deviation
caused by the transformer ratio error.
VSG output
frequency
correction
coecient
The default value is 100. Corrects the PCS output
frequency deviation.
VSG frequency
damping
coecient
The default value is 7.2. Species the power factor
that prevents the frequency change of the virtual
synchronous generator.
VSG excitation
time constant
The default value is 0. Species the time required
for the excitation of the virtual synchronous
generator to reach the rated voltage.
