摘要
基于免疫原理,对100%低地板城轨车辆辅助三相变压器进行定量的健康状态评估。首先建立车辆辅助三相变压器分层分析模型,并利用免疫原理构建变压器的免疫监控模型;同时采用层次分析法、模糊统计法和熵权法相融合的合作博弈法计算变压器各关键性能指标的复合权重;最后得到变压器的健康状态。研究结果表明:将合作博弈法应用于健康状态评估能紧密结合变压器的分层分析模型,并能直观地看到变压器中各关键性能指标的定量健康状态信息,节约判断变压器是否健康的时间,有效完成城轨车辆辅助三相变压器的健康状态评估。
Based on the immune principle,the health status of the auxiliary three-phase transformer of 100%low floor urban rail vehicles was quantitatively evaluated.Firstly,the hierarchical analysis model of vehicle-assisted three-phase transformer was established,and the immune monitoring model of transformer was constructed based on immune principle.At the same time,the composite weight of transformer performance index was calculated by cooperative game method which combined analytic hierarchy process,fuzzy statistics method and entropy weight method.Finally,the health status of transformer was obtained.The results show that the proposed health condition assessment method can be closely combined with the hierarchical analysis model of transformer,and can intuitively obtain the health status information of each performance index of transformer,and effectively complete the health condition assessment of three-phase transformer assisted by urban rail vehicles.
