摘　　要：针对船舶电力系统并网问题,在准同期并网原理的基础上,利用相位调节和频率调节的协同、频率变化率与功率转移的一致性及频率与功率的下垂特性改进柴油发电机组准同期并网策略。通过MATLAB/Simulink自建发电机准同期并网检测与判断模型,并按照实际船舶电力系统的流程进行从空载启动到单机投切再到双机并网的整个工况的仿真。仿真结果表明,该动态结果符合理论分析的预期结果,验证了该并网策略的可行性。The parallel operation of generators at change-over is one of the most important subjects in ship power system automation.The quasi-synchronization connection principle is analyzed and a diesel generator group quasi-synchronous connection strategy is proposed on the basis of the phenomenon of the process that the phase angle regulation and frequency regulation are the same in nature,and the frequency changes according to the power regulation with drooping characteristics.The simulation is performed to verify the feasibility of the connection strategy according to the actual process of ship electric power system.
