在船舶电站的运行过程中，双机甚至是多机组并联运行，是船舶电站的必不可少的组成部分，一般也为船舶电站的主要运行模式。而柴油发电机的并车操作过程是否合理，对船舶能否稳定运行有很大的影响。为探究船舶柴油发电机组并联运行的条件，建立了柴油发电机组的模型、船舶的电力负荷模型以及发电机并网触发控制模型。通过建立仿真模型，采用控制变量法，分析并车瞬间相关物理量的变化，在船舶电站相关电力器件的选型、船舶电站的设计以及船舶电网顺利完成并车操作方面，具有一定的指导与参考意义。
In the process of ship power station operation, dual or even multi-unit parallel operation is an essential part of ship power station, and is generally the main operation mode of ship power station. Whether the operation process of diesel generator is reasonable or not has a great influence on the stable operation of the ship. In order to explore the conditions of parallel operation of Marine diesel generator set, the diesel generator set model, the Marine power load model and the generator grid-connected trigger control model are established. Through the establishment of the simulation model, the control variable method is adopted to analyze the changes of the instantaneous related physical quantities of the parallel vehicle, which has certain guidance and reference significance in the selection of relevant power devices of the ship power station, the design of the ship power station and the successful completion of the parallel vehicle operation of the ship power grid.
