摘　　要：并联式气电混合动力系统存在部件间耦合严重、能量控制策略复杂等问题。为使系统多部件协同工作,提高系统能量效率,以应用于拖船的并联式气电混合动力系统为推进系统研究载体,通过仿真建模对混合动力系统部件进行解耦分析,基于蚁群算法设计了能量管理策略,使系统多部件协同工作。结果表明:相比于基于规则的能量管理策略,推进系统在基于蚁群算法的能量管理策略控制下使拖船航速跟随性提高了73%,平均能量效率提高了0.7%,等效气耗节约了8.3%,蓄电池组SOC变化值增加14.1%;实现了混合动力系统参数准确控制,提高了系统能量效率,为气电混合动力系统大规模普及应用提供了技术支持。The parallel gas-electric hybrid power system has problems such as serious coupling between components and complex energy control strategies.In order to make the multiple components of the system work together and improve the energy efficiency of the system,the parallel gas-electric hybrid power system applying for the tugboat was used as the research carrier of the propulsion system.The decoupling of hybrid power system components was analyzed by means of simulation modeling,and the energy management strategy based on ant colony algorithm was designed to make the multiple components of the system work together.The results show that the speed following ability of the tugboat under the energy management strategy based on ant colony algorithm is increased by 73%,compared with that under the rulebased energy management strategy.The average energy efficiency is increased by 0.7%,equivalent gas consumption saves 8.3% and the SOC change value of battery pack is increased by 14.1%,which realizes the accurate control of hybrid power system parameters,improves the energy efficiency of the system,and provides technical support for the large-scale popularization and application of gas-electric hybrid power system.
