【Abstract】 A simulation calculation method for ship electric power system dynamic process was proposed. System model was built with respect to rotating coordinate of the diesel generator connected to grid. Newton method and implicit trapezoidal integration method were used to solve differential algebraic equations. The speed governor controls generator frequency and active load sharing by speed droop. Voltage regulator introduces the concept of average voltage line. Ship power system of sino-rail bohai train ferries 1 was selected as simulation object. Dynamic process simulation of parallel running diesel generator sets was realized. The effectiveness of mathematic model and simulation method was demonstrated by simulation results.更多还原
