Fig. 4 Power characteristic in generator mode

Data provided by the diagram:

ƒ Max. regenerative power: P

gen,max

= 55 kW

ƒ Average regenerative power over 3 s: P

gen,ave

(3 s) = 34.375 kW

– In a time range of 3 s, the highest power is provided between t = 0  3 s.

The mean value is calculated for this range. The circumscribed area of

the curve represents the average power.

– Mean value for 3 s: P

gen,ave

= 13.75 kW

– Mean value for 3 s: P

gen,ave

= (55 kW ˘ 13.75 kW) × 0.5 = 20.625 kW
