Idle And Active Power - Bosch BPT-C 200 Betriebsanleitung

32 | Technical description
BPT-C 200, 300, 350 | Operating manual
The manufacturer requires you to provide:
The serial number of the central inverter display

Or the serial number of the Monitoring Display (manufacturer's BPT-M

Touch)
 The date on which you wish to change the parameters
The following can be configured in the display:
Grid monitoring

– Voltage
– Frequency
 Active power
– Power increase per minute after switch-on
– Response speed with specification of the nominal value by the
GridControl or PlantManager
– Response in the event of remote control signal failure
 Power factor cos φ
– Response speed with specification of the nominal value by GridControl
or PlantManager
– Specified cos φ
Please note that the consumer reference arrow system is applicable here.
Reference arrows indicate the direction in which the specified parameter
is to be assessed as positive. In the consumer reference arrow system,
the reference arrows for current and voltage are counted as positive in
the direction of the arrow and negative in the opposite direction of the
arrow. (Either the consumer or generator arrow system can be observed
here). The current and voltage arrows point in the same direction in the
consumer counting arrow system. The current and voltage are oriented in
the same direction to the load.
For more background information on the parameters, see the integrated
help pages and also the information on parameters in the download area of
the manufacturer's home page.

Idle and active power

For alternating current, the phase shift must be taken into account when
considering the output. With a phase shift of 90°, the output takes on
alternately positive and negative values. During a phase shift, idle power
occurs. Together with the active power, this forms the apparent power. The
difference between the idle power and the active power is that active
power is usable power and idle power is not.
