SHIPENGINEERING船舶工程Vol.45No.12023总第45卷，2023年第1期—103—基于飞轮储能技术的船舶区域配电系统冲击负荷供能策略洪远远，施伟锋（上海海事大学物流工程学院，上海201306）摘要：针对船舶区域电力系统中冲击负荷启停时引起的频率大幅度波动故障，采用飞轮储能系统，实现对冲击负荷的功率补偿和对系统频率波动的抑制。当飞轮充电时，采用按转子磁链的矢量控制方法对飞轮驱动电机的转速进行控制，以减少充电时间和过程扰动。当冲击负荷启动引起船舶出现功率缺额和频率波动时，触发飞轮装置进入放电工作模式，配合柴油机组为冲击负荷供电。飞轮储能系统内部自带变频器，能实现交流-直流-交流的转换，达到为冲击负荷稳定供电的目的。采用MATLAB/Simulink平台搭建适用于船舶系统的飞轮储能充放电模型，仿真结果表明，该系统能紧急满足冲击负荷的电能供应需求，从而预防船舶电网出现频率大幅度波动故障和加快故障自愈。关键词：船舶区域配电系统；飞轮储能系统；冲击负荷；频率波动；故障自愈中图分类号：U671.99文献标志码：A【DOI】10.13788/j.cnki.cbgc.2023.01.16ImpulseLoadEnergySupplyStrategyofShipRegionalDistributionPowerSystemBasedonFlywheelEnergyStorageTechnologyHONGYuanyuan,SHIWeifeng(LogisticsEngineeringCollege,ShanghaiMaritimeUniversity,Shanghai201306,China)Abstract:Aimingatthefrequencyfluctuationcausedbythestartandstopofimpactloadintheregionalpowersystemofships,theflywheelenergystoragesystemisusedtorealizethepowercompensationofimpactloadandthesuppressionofsystemfrequencyfluctuation.Duringflywheelcharging,thespeedofflywheeldrivemotoriscontrolledbyvectorcontrolmethodaccordingtorotorfluxlinkagesoastoreducechargingtimeandprocessdisturbance.Whenthepowershortageandfrequencyfluctuationoftheshiparecausedbythestart-upoftheimpactload,theflywheeldeviceistriggeredtoenterthedischargeworkingmodeandcooperatewiththedieselunittosupplypowertotheimpactload.Theflywheelenergystoragesystemhasitsownfrequencyconverter,whichcanrealizeAC-DC-ACconversionandachievethepurposeofstablepowersupplyforimpactload.UsingMATLAB/Simulinkplatform,aflywheelenergystoragecharginganddischargingmodelsuitablefortheshipsystemisestablished.Thesimulationresultsshowthatthesyste...
