摘要
对于未来的全电力船舶,直流区域配电成为重要选择。为探索船舶能量管理系统中占全船电力负荷最大的推进负载对直流区域配电系统的暂态影响,在理论分析的基础上,利用matlab/simulink软件,构建了船舶直流区域配电系统仿真模型,系统包括DC\DC、DC\AC等电力转换器件以及必要的附件。通过仿真,验证了理论推导,发现电力推进系统在加速过程中对直流区域配电电压稳定存在影响,该影响对于不同的系统剩余功率、分级方式、加速速率,影响也不同。为研究如何能够在稳定性容许范围内最快速的加载推进负载提供了理论基础。
For future overall-electric ships,DC-zonal electrical distribution will be an important choice due to its unique advantages.In order to explore the influence of electric propulsion on DC zonal electrical distribution system（DC-ZED） in ship power management system（SPMS）,a model of DC-ZED is constructed by using matlab/simulink.The model with multi-terminal blocks includes power converter modules and required accessories.The simulation validates the theoretical analysis of it.It is found that electric propulsion system has influence on the stability of DC bus voltage during its acceleration process.This influence is different for different spare power,hierarchical arrangement and accelerating rate of the system.A theoretical basis of the highest propulsion loading rate within an allowable margin of stability is given.
