New (page 38): Active power limitation during grid
underfrequency
In some grid codes and standards it is required that the maximum active output power of the inverter
is increased as the grid frequency decreases. The PVS800 has an adjustable active power limitation
curve based on the measured grid frequency.
The active power limit starts to increase when the grid frequency is below
shown in the figure below. The active power limit cannot decrease while the grid underfrequency
situation is ongoing. As the grid frequency returns to a normal level defined by parameter
PLIM RET FREQ, the active power limit is ramped down to the level defined by parameter
PLIM LEVEL 1.
