针对船舶的不间断供电需求，提出一种结合电池储能系统和柴油发电机（Diesel Generator Set，DGS）的应急供电系统控制策略。根据船舶电源的工况和负载需求，灵活调整储能变流器的工作模式，确保在常态电源故障时应急电源的快速无缝投切，保证船舶的不间断可靠供电。首先，引入模型预测控制（Model Predictive Control，MPC）技术代替恒流恒压（Constant Current-Constant Voltage, CC-CV）充电和V/F控制及PQ控制的电流内环，减少参数设置，提高电能质量；其次，通过深入分析CC-CV控制、V/F控制和PQ控制的控制特性，针对不同控制间切换工况下易造成的电气波动，设计相应的切换方法，实现控制的平滑过渡。最后，在Matlab/Simulink构建船舶供电仿真模型，验证所提控制策略的可行性与有效性。
Aiming at the uninterruptible power supply requirements of ships, a control strategy of emergency power supply system combining battery energy storage system and diesel generator set (DGS) is proposed. According to the working conditions and load requirements of the ship's power supply, the working mode of the energy storage converter is flexibly adjusted to ensure the rapid and seamless switching of the emergency power supply when the normal power supply fails, and ensure the uninterrupted and reliable power supply of the ship. Firstly, model predictive control (MPC) technology is introduced to replace constant current-constant voltage (CC-CV) charging and current inner loop of V/F control and PQ control, reducing parameter setting. Improve power quality; Secondly, through in-depth analysis of the control characteristics of CC-CV control, V/F control and PQ control, according to the electrical fluctuations easily caused by different switching conditions between controls, the corresponding switching method is designed to achieve smooth transition of control. Finally, the ship power supply simulation model is built in Matlab/Simulink to verify the feasibility and effectiveness of the proposed control strategy.
