Abstract

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.
