3.) Determining the pulse value
The maximum work (power demand), which
can be imported in an hour is:
Work = active power demand * time
Work = 400kW *1h
Work = 400kWh
If a pulse value of 400kWh per pulse is set, at
full load the UMG96S supplies one pulse. This
equates to a pulse frequency of
= 1 pulse/h
= 1 pulse/36000 sec.
= 1/3600 Hz
= 0.00028 Hz
This pulse value produces very few pulses. It is
not possible to observe the work within the min-
utes range.
But the UMG96S can supply up to 10 pulses
per second (10Hz) and the data collector can
record 50 pulses per second (50Hz). One pos-
sible solution is that the UMG96S supplies
pulses with a frequency of 10Hz at 400kW, or
for safety not until 500kW.
= 500kWh
Work in one hour
= 500kWh / 3600
= 0.14kWh
= 140Wh
Work in one second
= 140Wh / 10
= 14Wh
Work in 1/10 seconds
I.e., if 10 pulses per second are output by the
UMG96S with a pulse value of 14Wh, this
equates to 500kW of work in one hour.
