摘　　要：及时准确地评估高铁牵引供电系统的健康状态有利于保证高速机车运行的安全准点。为实现对牵引供电系统运行状况及健康状态的监测及评估,借鉴生物系统的免疫原理,提出了分层免疫监控模型,利用免疫agent对牵引供电系统状态进行监测,利用层次分析法(analytical hierarchy process,AHP)确定不同层次之间的影响权重,将各设备传感器的输出作为抗原输入,可对牵引供电设备及系统的健康状态做出定量评估。京沪高铁无锡—昆山段供电系统的分析结果表明,该方法能对供电系统的运行状态有直观地认识,有利于对故障的设备进行及时准确地处理。It is favorable to ensure the security and on schedule of high-speed train to monitor and evaluate the health state of traction power system for high-speed railway in time and accurately.Referring to biological immune mechanism a hierarchical immune monitoring model is proposed.In the proposed model the immune agents are used to monitor the state of traction power supply system and the influencing weights among different hierarchies are determined by analytical hierarchy process（AHP）;taking the outputs of sensors installed on various equipments as antigen inputs,the quantitative evaluation on health states of traction power equipments and traction power supply system can be implemented.Results of analysis on power supply system for the section from Wuxi to Kunshan of high-speed railway from Beijing to Shanghai show that the proposed method can give intuitive description of traction power supply system’s operation condition and contributes to timely and are favorable to cope with faulty equipments in time and accurately.
