... the values of the nominal power of the generator. The paper proposes the actual load on the bus of the main switchboard (MSB) to distribute between the parallel operating units so that the extent to which they meet the minimum load the specific fuel consumption, which is typically 75-85 % of the nominal power of DGA, or was close to such value while respecting the rules PMPS. In addition, the article describes the features of a single work of DGA of ship plants that contain generators of different power ratings, and recommendations are given to reduce the specific fuel consumption when a single work by transferring power backup DGA depending on the actual load on the bus of the main switchboard.
