PAUSE. If the parameter 6182 T U PULS MAX is set to ∞ there is no time restriction and a continuous pulse is
output until the calculated time has expired.
In particular with hydro-electric power stations, generator rotation speed can be subject to fluctuations.
Actuator commands established from a current frequency value could thus be incorrect. The option is there-
fore provided using the parameter 6186 SMOOTHING f of subjecting the frequency difference to an aver-
aging with different smoothing factors 1 to 10.
If the frequency difference is Δf ≈ 0 i.e. the generator runs in synchronism with the power system but the
connection conditions are not yet fulfilled, synchronization would not be possible or would take a very long
time. In such cases a "kick impulse" can be issued if the parameter 6187 KICK PULSE = ON was selected and
kick impulses thus enabled. These are issued only if the duration until synchronism exceeds an adjustable time
set by parameters 6189 T SW-ON MIN. This insures that kick impulses are not issued immediately before
synchronism is achieved, but only if the voltage vectors are not coinciding in the immediate future. For the set
value of the parameter 6189 applies the formula: T SW-ON MIN ≈ 1/(2·Δf). The highest of the both set values
of the parameter 6132 df ASYN f2>f1 and 6133 df ASYN f2<f1 are selected for Δf.
The kick impulse is initiated in the direction of the parameter setting from Δf KICK (according to the positive
or negative signs of the frequency value). Its length is calculated from the frequency change df2/dt and the set
value of the parameter 6188 Δf KICK.
