Q/P rated (change by active power curve):
With the setting P
3
Q (change by active power curve), the Q/Pn value is determined by
means of a configurable curve. The P value (total active power) is determined through the
main current transformer by three-phase projection. The parameters refer to Pn (rated
active power of the power plant).
The Q/Pn2 value (power recovery) has no function in this mode.
The Q/Pn1 value (power consumption) is used for the baseline between the adaption
ramps. A hysteresis can be programmed using the “hyst.” parameter.
The transition to the new Q/Pn value can be attenuated using the “t-delay” parameter.
New values are adopted once per second.
