| Abstract:To be used as marine generation sets, a certain marine diesel has high requirement regarding to the transient performance. However, the speed governing accuracy of the original diesel gensets was degree 3, and needed to be improved to degree 2. The 1D transient simulation model was built and calibrated by both steady and dynamic engine testing data. With regard to the gap between the speed governing performance of the original gensets and targeted requirement, the optimization method of improving speed governing accuracy was put forward. The method was verified to be feasible and practical through simulation calculation, and could meet with degree 2 speed governing accuracy . |
