When the two diesel generator sets are side-by-side with no load, there will be a frequency difference and voltage difference between the two sets. And on the monitoring instrument of the two units (ammeter, power meter, power factor meter), the actual inverse power situation is reflected, one is the inverse power caused by inconsistent speed (frequency), the other is the inverse power caused by unequal voltage, which is adjusted as follows:
1, the frequency caused by the adjustment of the inverse power phenomenon: if the frequency of the two units is different, the difference is large, the instrument (ammeter, power meter) shows that the current of the unit with high speed is positive, the power meter indicates positive power, and on the contrary, the current indicates negative value, and the power indicates negative value. At this time, adjust the speed (frequency) of one of the units, adjust according to the indication of the power meter, and adjust the indication of the power meter to zero. The power indicator of the two units is zero, so that the speed (frequency) of the two machines is basically the same. However, when the ammeter still has an indication at this time, this is the inverse power phenomenon caused by the voltage difference.
2, the voltage difference caused by the adjustment of the reverse power phenomenon: when the two units of the power meter indication is zero, and the ammeter still has a current indication (that is, a reverse and a positive indication), you can adjust the voltage adjustment knob of one of the generator set, adjust, according to the ammeter and power factor indication. The ammeter’s indication is eliminated (that is, adjusted to zero), and after the ammeter has no indication, the power factor is adjusted to more than 0.5 according to the power factor meter’s indication. Generally can be adjusted to about 0.8, for the best state.
