Research on Security Risk Assessment for Traction Power Supply System of High-speed Railway

To reduce security risk level of the traction power supply system of high-speed railway and achieve safe and reliable operation of high-speed railway in its life cycle, the security risk assessment for the traction power supply system of high-speed railway was summarized in the paper. The sources of security risk were expounded in three aspects:equipment performance decline,service environment and maintenance activities of operator. From the three aspects, the current research status on the risk assessment for power system and traction power supply system were summarized. With the rapid development of high-speed railway, such problems and challenges as incompleteness and uncertainty of data,complexity of service environment and lack of fault diagnosis and maintenance mode were analyzed. Future research on the security risk assessment was discussed, it is pointed out that the attention of the research on security risk assessment for traction power supply system should be paid to the following four aspects:data acquisition,assessment model,risk fusion and application of risk assessment.
