摘　　要：随着锂电池储能技术不断完善,国内外锂电池储能电站不断增多,储能单元运行情况越来越受到运行单位重视。本论文在研究电池电压极差、电池电压标准差系数、温度极差、SOE极差、组串运行效率等部件评估指标,以及单元运行效率、功率波形相似度等储能单元整体评估指标的基础上,对储能单元运行状态进行了实例分析。评估结果表明,上述指标为评估锂电池储能单元运行状态提供了技术手段,对于安排储能电站检修维护,提高储能电站运行效率具有指导意义。As the lithium battery energy storage technology is constantly developed in recent years, a lot of large scale lithium battery energy storage stations were put into operation at home and abroad, and increasing attention is paid to the running state of energy storage lithium batter. Based on the study of part assessment indicators, such as range of battery voltage, coefficient of standard deviation of battery voltage,range of battery temperature, range of SOE, string operation efficiency, and overall assessment indicators, as well as unit operation efficiency, power waveform similarity, we analyse the running status of battery energy storage units in operation. The results show that it provides technical method for the running status assessment of battery energy storage unit, and it has guiding significance to arrange the BESS maintenance reasonablely and ensure the BESS operation efficiently.
