建立一个全钒液流电池系统模型，通过对全钒液流电池系统模型在不同管径和流速下的泵损耗进行理论分析和研究，得出全钒电池泵损耗的规律。运用Fluent模拟仿真半电池在不同流速下的电解液分布，不同充电电流和流速下对全钒液流电池性能的影响。结果表明：根据钒电池结构优化控制泵的损耗和电解液流速，对于提高钒电池储能系统的效率和改善电池系统稳定性至关重要。在大规模应用储能技术时，泵损和流速的影响将更为明显。

A vanadium redox flow batteries system was modelling. Through theoretical analysis and research on the all vanadium redox flow batteries system under different pipe diameter and velocity of pump loss,the pump depletion of the law is concluded. Using the Fluent software simulate half cell electrolyte distribution under different flow rate,the performances of all vanadium redox flow batteries are affected by different charging current and velocity. Results show that according to the loss of vanadium battery structure optimization control pump and the electrolyte flow rate,it is very important to improve the efficiency of vanadium battery energy storage system and the battery system stability. In the large scale energy storage technology,the pump damage and the influence of flow rate are more apparent.
