摘要：
The reliability of UHVDC (ultra-high voltage direct current) transmission system is significant to the development of power grid. The paper selects dual 12-pulse converters on each pole to model and analyze the UHVDC transmission system. Firstly, the system is divided into six subsystems to evaluate the reliability by the fault tree analysis method. Then based on the fault frequency and the repair time of each subsystem's bottom components, the paper calculates the fault frequency and the repair time of each subsystem. Using the frequency and duration method, the paper calculates the fault probability, fault frequency and repair time of the whole system. Finally, it is validated by the actual data of typical lines.
