Peculiarities of parallel operation of diesel-generator units of a ship power plant

The study of the operation power stations existing on ships shows need to ensure reliable parallel diesel generators (DGs). It is known that main reason for unstable DG a small or different droop mechanical characteristics drive motors. A generator sets at ship plant, consisting four with electronic speed controllers provide necessary droop, also showed its instability. measurements and consideration physical processes revealed an uneven distribution reactive due differences in external generators. elimination instability possible only by introducing additional devices fine-tuning regulators obtain similar droop. trouble-free proposed system was confirmed long-term tests during normal mode navigation.
