未来舰船综合电力系统将采用中压直流分布式供电网络结构，其动态特性易受故障、投切负载、脉冲负荷等影响，需配置储能模块以满足系统供电需求。为此，该文设计了由异步电机、飞轮和双向变流器三大模块组成的直流并联型飞轮储能装置，以空间矢量脉宽调制(space vector pulse width modulation，SVPWM)技术为基础，提出了飞轮调节阶段“电压外环+电流内环”和保持阶段“转速外环+电流内环”的双模式双闭环控制策略，以及相应的飞轮工作模式自动切换流程。通过构建飞轮储能装置试验平台及对应仿真系统，完成了突加负载时的仿真、试验对比分析，结果表明，所设计的飞轮储能装置能够根据系统监测结果自动切换工作模式，调整直流主网电压，补偿系统功率，有效抑制舰船综合电力系统的电压波动，提高供电品质。

The medium-voltage DC distributed network will be applied in future vessel integrated power systems (IPS), which might make the system dynamics sensitive to effects like faults, loads switching and pulse loads, so the energy storage system is required for better power quality. The flywheel energy storage (FES) system shunt to the DC bus of IPS and composed of an asynchronous motor, a flywheel and a bidirectional converter were introduced. Based on the space vector pulse width modulation (SVPWM), a dual-mode, dual-loop control strategy of the FES together with its automatic switching schedule of operation modes was proposed. According to the strategy, there were an outer loop of voltage and an inner loop of current during the adjusting phase of the FES, while during the holding phase, the inner loop of current remained the same but the outer loop turned to be of speed instead. Test beds of the FES were constructed, where the sudden loading experiment and simulating, have been done. The comparison and the analysis of the results indicate that the designed FES can switch its operating modes automatically according to the monitoring signals, and is competent to regulate the DC bus voltage and compensate the unbalanced power flow during disturbances. Thus the voltage fluctuations of the IPS can be suppressed and the power quality can be improved.
