摘要
为了实现节能减排的目的,对某传统的耙吸式挖泥船动力系统进行混合动力系统模拟改装,使用柴油机和蓄电池作为混合动力源,采用阈值法作为能量管理策略,根据不同的功率需求及蓄电池的荷电状态调整系统的工作模式,并在Matlab/Simulink环境下建立动力系统的燃油消耗及排放模型。仿真结果表明,混合动力系统较原系统在油耗和排放方面均有较大的改善。
In order to achieve the purposes of energy saving and emission reduction, the traditional trailing suction hopper dredger was retrofitted from a diesel engine power system to a hybrid power system by simulation. The hybrid power system, using diesel and battery as the power sources, could adjust the operation mode according to different power demand and the state of charge of battery with energy management strategy. The fuel consumption models and emission models were built in Matlab/Simulink environment. The results showed that the hybrid power system has significant improvement in fuel consumption and emission compared with the original system.
