| 摘要:针对带脉冲负载的电池储能系统（battery energy storage system with pulsed load，BESS-PL）源载耦合和脉冲特性建模问题，采用状态空间法和信号平均法分别构建了BESS-PL源载耦合精确模型和平均模型，基于此提出了一种准精确建模方法，对高频分量合理简化，保留了BESS-PL特有的脉冲特性，从而构建BESS-PL源载耦合准精确模型。通过稳定性理论分析和仿真，对比3种BESS-PL源载耦合数学模型的特点和不同适用情况。其中，基于平均模型推导BESS-PL系统的稳态传递函数，利用波特图分析讨论脉冲占空比和DC/DC变换器开关占空比对稳定性的影响规律；结合3种模型仿真，分析了BESS-PL系统关键参量和源载功率的关联规律、脉动特性及占空比对稳定性的影响规律。3种建模方法可灵活用于BESS-PL系统源载耦合特性和脉冲特性的暂稳态分析。 |

| Abstract: Aiming at the modeling problems of the source-load coupling and pulse characteristics of the battery energy storage system with pulsed load (BESS-PL), the source-load coupling precise model and average model of BESS-PL were respectively constructed by the state space method and the signal average method. Based on these two models, a quasi-precise modeling method was proposed, which can reasonably simplify the high-frequency components and retain the unique pulse characteristics of BESS-PL. Through stability theory analysis and simulation, the characteristics and applications of three BESS-PL source-load coupling mathematical models were compared. The steady-state transfer function of BESS-PL system was deduced based on the averaged model, and the influence laws of pulse duty ratio and DC/DC converter switch duty ratio stability were discussed on the analysis of the Bode diagram. The correlation laws of key parameters and source-load power, pulsation characteristics and the influence laws of duty ratio stability of BESS-PL system were analyzed combined with simulations of the three models. The three BESS-PL source-load coupling mathematical modeling methods can be flexibly used for transient steady state analysis of source-load coupling characteristics and pulse characteristics of BESS-PL system. |
