摘　　要：全钒液流电池(VRB)作为一种新型储能电池,具有功率密度和能量密度独立控制、充放电循环寿命长、放电深度大、维护简单等优点,既适合电力系统独立储能电站应用,也适合风电场平抑功率波动。通过对VRB工作原理的研究,以VRB电化学反应和能斯特方程为基础,基于Matlab/Simulink构建出完整的VRB模型;以额定功率为5.5 kW、额定容量为11 kWh的VRB为例,对VRB在恒电流充放电模式下的荷电状态及充放电特性进行了详细的仿真研究。As a new type of storage energy battery, all vanadium redox flow battery （VRB）, which is a power density and energy density independent control, long cycle life of charge and discharge, high depth of discharge, advantage of simply maintaining, can be not only fit for the application of independent storage energy power station in power system, but also for stabilizing power fluctuation in wind farm. A complete VRB model was built through the research of VRB＇s working principle, by the electrochemical reaction and the Nernst equation as the foundation and based on the Matlab/Simulink platform. With rated power of 5.5 kW and nominal capacity of 11 kWh VRB as an example, the simulation study of SOC and feature was discussed detailedly under the VRB model of constant current charge-discharge
