Zusammenfassung:	The invention discloses a power distribution network reliability evaluation method and system considering element fault randomness, and the methodcomprises the steps of an obtaining step: obtaining the connection relation of power distribution network operation elements according to a power distribution network structure diagram; a screening step: screening out a fault element from the power distribution network operation elements; a determining step: determining the actually disconnected section switches in the upstream section switch set of the current fault element after each fault elementhas a fault; a first calculation step: based on the actually disconnected section switch, calculating the power vacancy and the power shortage probability of all fault elements after the fault; and asecond calculation step: calculating the power shortage expectation and the power shortage probability of the power distribution network based on the power shortage and the power shortage probabilityof all the faulty elements
