When choose diesel generator set, there are many standard to be consider, such as frequency transient regulation, frequency stabilization time, frequency volatility, noise and so on.
2.Frequency stabilization time of diesel generator set: ≤ 250kw> 250kw 5s ≤ 5s
3.The frequency volatility of Cummins diesel generator: ≤ 250kw> 250kw ≤ 0.8% ≤ 0.5%
4.Three-phase voltage deviation of Cummins diesel generator under asymmetric load. When diesel generator set at 25% three phase load, in any phase plus 25% of the calibration phase power resistive load, the diesel generator set should be able to work, the maximum or minimum value of line voltage and line voltage average of three is 5%.
5.Noise of Cummins diesel generator: the the average noise sound pressure at 1m away from diesel generator set and generator units should:
≤ 250KW> 250KW
≤ 102db (A) ≤ 108db (A)
6.The fuel consumption rate of Cummins diesel generator. The rated power of diesel generator set should in the range of 120 <600KW, the fuel consumption should ≤ 260G.
