摘　　要：电容器蓄电池在储能特性、充放电速度和功率密度等方面存在差异,使得电力信号的单位存储量较低,导致电量传输稳定性较差。为此,提出基于能量转换模型的电容器蓄电池混合储能方法。按照能量转换模型,求解电容器能量输出特性方程,联合能量转换参数,跟踪电容器功率。分析电容器蓄电池储能特性,通过双向DC/DC变换器建模,确定单位储能量,完成基于能量转换模型的电容器蓄电池混合储能方法的设计。实验结果表明,该方法可将电能信号的输出功率控制在3.5~4.8 kW的数值范围之内,不会因电量信号的非平稳传输而造成电容器设备实时储能能力下降,能够提升电容器蓄电池中电力信号的单位存储量。Capacitor batteries have differences in energy storage characteristics,charging and discharging speed and power density,which makes the unit storage capacity of power signals low,resulting in poor power transmission stability.Therefore,a hybrid energy storage method of capacitor and battery based on energy conversion model is proposed.According to the energy conversion model,the capacitor energy output characteristic equation is solved,and the energy conversion parameters are combined to track the capacitor power.The characteristics of capacitor and battery energy storage are analyzed,and the unit energy storage is determined through the modeling of bidirectional DC/DC converter,and the design of capacitor and battery hybrid energy storage method based on energy conversion model is completed.The experimental results show that the proposed method can control the output power of the power signal within the value range of 3.5~4.8 kW,and will not reduce the real-time energy storage capacity of the capacitor device due to the non-smooth transmission of the power signal,and can increase the unit storage capacity of the power signal in the capacitor battery.
