摘　　要：为充分利用飞轮储能对船舶直流微电网功率补偿的优势,弥补燃气轮机发电系统输出功率调节响应慢的不足,对船用燃机直流微电网大功率负载下的飞轮储能系统控制策略和电网响应特性进行研究。本文基于100 kW实装微型燃气轮机发电机组,建立了包括燃气轮机、发电机、飞轮储能系统的船舶直流微电网模型,并在有无飞轮储能系统的情况下,分别突加、突卸40%、60%、80%额定功率负载,详细分析不同负载模式下直流母线电压、发电机转速和飞轮转速的变化特性。结果表明,所提出的飞轮储能系统控制策略可以及时补偿大功率负载冲击下发电机和负载之间功率不平衡,防止母线电压和同步发电机转速波动过大,有效提升微型燃气轮机发电系统的电能质量和稳定性。In order to make full use of the advantages of flywheel energy storage in power compensation of marine DC microgrid and make up for the shortage of slow output power regulation response of gas turbine power generation system,the control strategy of flywheel energy storage system and the grid response characteristics under high power load of marine gas turbine DC microgrid are studied.Based on a practical 100 kW micro gas turbine generator set,a marine DC microgrid model including gas turbine,generator and flywheel energy storage system is established.The changes of DC bus voltage,synchronous generator speed,are studied by abruptly loading and unloading 40%,60%and 80%rated loads with or without flywheel energy storage system.The results show that the control strategy of the flywheel energy storage system proposed in this paper can compensate the power imbalance between the generator and the load in time,prevent the bus voltage and synchronous generator speed from large fluctuation,and effectively improve the power quality and the stability of micro turbine generation system.
