摘　　要：全钒氧化还原液流电池凭借它的诸多优势,在电力系统中的应用潜力巨大,前景广阔,然而目前尚未有较为统一的仿真模型。以钒电池的电化学原理为基础,推导了以钒电池荷电容量和初始离子浓度为参量的电压方程,通过三组实际系统对仿真模型进行了验证。在此模型基础上,仿真分析对比了钒电池常见的恒功率和恒电流的充放电方法的各项效率指标。With various advantages, all vanadium redox flow battery is a promising technology in power system. However, the simulation model of vanadium redox battery has not yet been united. Based on the electrochemical principal, the voltage function with the initial ion concentrations and the state of charge as parameters was deduced. The proposed model was then verified by comparing the simulations results with measured data taking from three different actual systems. Moreover, simulations of the constant power charging and constant current charging methods were taking out and their efficiencies were analyzed.
