3.2.8 Inverter active power setting: power limit
During changing in AC operation and control or changing in energy source operation, the active power generated by the
inverter shall not exceed a specified gradient expressed as a percentage of the active nominal power of the inverter per
minute. You can set ‘Active power gradient for increasing’ and ‘Active power gradient for reducing’ according to the
requirement.
The grid company maybe requires reduction of active power on set point. You can set ‘Active power limit’ according to the
requirement.

3.2.9 Inverter active power setting: overfrequency curve
The inverter may be capable of activating active power response to overfrequency at a programmable frequency threshold
with a programmable droop. There are four available modes.
Fix gradient and non-hysteresis: ∆P is the active power as a percentage of Pn, the inverter provide non-hysteresis in the
control of active power response to over-frequency.
Fix gradient and hysteresis: ∆P is the active power as a percentage of Pn, the inverter provide hysteresis in the control of
active power response to over-frequency.
Variable gradient and non-hysteresis: ∆P is the active power as a percentage of PM, the inverter provide non-hysteresis in
the control of active power response to over-frequency.
Variable gradient and hysteresis: ∆P is the active power as a percentage of PM, the inverter provide hysteresis in the
control of active power response to over-frequency.
The below figure descripts the difference between hysteresis and non-hysteresis control
Here,
fn: Rated frequency
freset: Reset frequency
fstart: Starting frequency
fstop: Stopping frequency
∆P : Active power in percentage during reducing
Intentional delay time for P(f) is only active for the activation of the function, once the frequency rises above fstart and the
intentional delay time plus inherent dead time is less than 2s. Once the function is operating, the established control loop is
not intentionally delayed.
Min. delay time for active power release is the delay time that the active power can increase after the frequency below
freset.

3.2.11Inverter reactive power setting: running mode
The inverter may be required to participate to voltage control by means of production and absorption of reactive power.
There are seven reactive power control modes. Only one mode may be active at a time.
The inverter acts as a load from the perspective of the grid according to the country standard. This means the inverter
operation in Quadrant II (under-excited) or III (over-excited) as below.
Over-excited reactive power also known as Capacitive reactive power or Leading power factor.
Under-excited reactive power also known as Inductive reactive power or Lagging power factor.
Tap ‘Reactive power control mode’ to choose the mode. The ‘Time constant 3(τ)’ should be set first. The reactive power
change maybe required to correspond with a first order filter. The ‘Time constant 3(τ)’ is three time constant of the filter
and is the time until 95% of the nominal value is reached.

3.2.12Inverter reactive power setting: fixed power factor
The fixed displacement factor cosφcan be set.
Fig. 26: Fixed power factor
3.2.13Inverter reactive power setting: Cos(Φ) – P curve
The power related control mode cosφ(P) controls the cosφof the output as a function of the active power output.
There are four coordinate points that are adjustable in the curve as shown in the figure below.
The coordinate points are the active power as a percentage of Pnand the displacement factor cosφ.
Some grid companies may require two voltage thresholds as a percentage of Unto activate or deactivate this function.
These voltage thresholds are referred to as the ‘lock-in’ and ‘lock-out ’voltage.
Activation threshold as a percentage of Uncorresponds to ‘lock-in’ voltage
Deactivation threshold as a percentage of Uncorresponds to ‘lock-out’ voltage
