10.1 Ambient condition power modification
Modified coefficient table of ambient condition power
The conditions of generator rated output:
Altitude: 0 m Ambient temperature: 25℃ Relative humidity: 30%
Ambient modified coefficient: C (Relative humidity 30%)
Ambient temperature (℃)
Altitude
(m)
25 30 35 40 45
0 1 0.98 0.96 0.93 0.90
500 0.93 0.91 0.89 0.87 0.84
1000 0.87 0.85 0.82 0.80 0.78
2000 0.75 0.73 0.71 0.69 0.66
3000 0.64 0.62 0.6 0.58 0.56
4000 0.54 0.52 0.5 0.48 0.46
Note: When the relative humidity is 60%, the modified coefficient is C-0.01
When the relative humidity is 80%, the modified coefficient is C-0.02
When the relative humidity is 90%, the modified coefficient is C-0.03
When the relative humidity is 100%, the modified coefficient is C-0.04
Counting example:
When the rated power of generator is PN =5KW, altitude is 1000m, ambient temperature is 35℃,
relative humidity is 80%, the rated power of generator is:
P=PN ×(C-0.02) = 5 × (0.82-0.02) = 4KW
Ambient condition:
1000 mbar, 25℃, relative humidity: 30％, the rated power can meet with ISO 3046.
1-P.R.P. Prime Power
－
ISO8528：the normal power indicates that the maximum power running
continuously in fluctuant load, and within the maintaining interval. In case of 24 hours
continuous running, the average using rate should not exceed 80% of the normal power.
2-Standby power (ISO3046 Fuel Stop power): the stand-by power indicates the maximum
running power of generator set. In case of fluctuant load or emergency, the generator set annual
running term should not exceed 500 hours, the annual running term at 100% load should not
exceed 25 hours, and the annual running term at 90% load should not exceed 200 hours.
Overload is prohibition.
