摘要:

为了改变储能电站电池由于运行不良引发的火灾和爆炸事故频发的现状,本工作介绍了一种基于组合赋权与逼近理想解排序法(technique for order preference by similarity to ideal solution,TOPSIS)的储能电站电池安全运行风险评价方法。首先,通过查阅文献、标准规范和事故调查报告等手段统计识别发生事故的原因,并在已有标准规定的前提下,描述了电池运行中应具备的安全状态。从电池基本情况、电池使用工况、外部刺激、运行环境、安全监控保护系统、人为因素6个方面建立风险评价体系。其次,利用层次分析法(analytic hierarchy process,AHP)和熵权法分别确定风险评价体系中指标的主观权重和客观权重,并对2种权重进行组合。最后,使用TOPSIS法与标准值进行比较来对电池安全运行风险作综合评价。将该方法应用于4所储能电站的电池运行风险评价中,评价结果显示,其中3所储能电站电池运行虽然存在问题,但总体的安全状况相对良好,另有1所储能电站电池在运行风险指标管理多方面存在较严重问题并亟须改进。结果符合各现场电池运行风险的实际情况,证明了该方法具有合理性和可行性。

Abstract:

This study introduces a risk assessment method for the safe operation of batteries based on a combination of weighting and technique for order preference by similarity to ideal solution (TOPSIS) to prevent and improve the current situation of frequent fire and explosion accidents caused by poor battery operation in energy storage power stations. First, the causes of accidents are identified by consulting literature, standard specifications, and accident investigation reports, and the safe condition that the battery should have during operation is described based on current standards. The risk assessment system is established from six aspects: the battery's basic situation, the battery's service condition, external stimulation, the operating environment, the safety monitoring and protection system, and human factors. Second, the subjective and objective weights of indicators in the risk evaluation system are determined using the analytic hierarchy process and entropy weight method, and the two weights are combined. Finally, the TOPSIS method is compared with the standard value to comprehensively evaluate the battery's safe operating risk. This method is applied to the battery operation risk assessment of four energy storage power stations. The evaluation results show that three of them have some issues with battery operation, but the overall safety situation is relatively good, while one has more serious problems in the operation risk index management and urgently requires improvement. The results are consistent with the actual situation of battery operation risk at each site, demonstrating that the method is reasonable and feasible.
