Abstract
The accurate evaluation of distribution system reliability plays an important role in distribution system planning. The existing method doesn’t consider the influence of different inclement weather. This paper proposed a new method for evaluation of distribution system anti-disaster ability in inclement weather. Firstly, the influence of the system components in inclement weather was analyzed according to the physical situation; then the relationship between the breakdown probability of the components and the meteorological parameters was studied on the basis of the components quality. Secondly, considering the characteristics of distribution system, the probability of continuous failure was discussed by the minimal path method. Finally the evaluation indices were introduced to represent the distribution system anti-disaster ability. The simulation results show the laws between the distribution system’s anti-disaster ability and the changing meteorological parameters.
