This analysis evaluates active power and crankshaft speed changes during the start-up of marine diesel generators, indicating potential efficiency improvements.
The article describes the results of a study of transient processes of a diesel generator set during start-up. The analysis of changes in the active power, torque and speed of rotation of the crankshaft from the moment of start-up to reaching steady-state operation is carried out. To register the parameters of the transient process, a SCADA system was used, which provided reliable data in real time. The results showed that the transients in the studied parameters have different durations. The longest is the transient process in terms of crankshaft speed. The graphs obtained in the course of the research provide the information necessary to assess the quality of the transients. The conducted research helps to identify opportunities for improving the efficiency of the control system of diesel generator sets during start-up and transition to steady-state operation.
