摘　　要：为提升锂电池组在船舶直流电网中并联运行的稳定性,根据多电源模块的并联均流工作原理,针对具有不同输出特性的储能模块,建立“储能模块-DC/DC变换器-直流母线”并联Simulink模型,并提出基于电压电流双闭环控制的改进均流控制策略。设置开环控制、电压单闭环控制和电压电流双闭环控制等3组仿真模型,进行均流与未均流控制对比,验证该策略的有效性。试验结果表明,该策略能有效改善船舶直流母线的电压稳定性,减少电流不均衡现象,同时提升船舶电力系统的性能和安全性。In order to enhance the stability of lithium battery packs operating in parallel on a ship’s DC power grid,the system is mathematically modeled and the control algorithm is developed.A Simulink model of parallel“Energy Storage-DC/DC-DC Bus.”is built to simulate different output characteristics of energy storage modules.An improved current equalization control algorithm based on voltage-current dual-loop control is devised.The algorithm calculates the mean square deviation of voltagecurrent simulation data and analyzes the current equalization accuracy.Experimental results demonstrate that this strategy effectively improves the voltage stability of the ship’s DC bus,reduces current imbalance,and enhances overall system performance and safety.
