Zusammenfassung:The invention relates to a network health index assessment method for a power distribution network, and the method comprises the steps: (1) determining the range of a power supply region of the power distribution network; (2) determining the fault rate lambda of key equipment according to a function relation between an HI (health index) and a fault rate lambda of key equipment of the power distribution network; (3) simplifying the power distribution network; (4) determining the power supply reliability P of the power distribution network; (5) determining the HI' of the power distribution network. The method provided by the invention employs the HI to describe the function and performance of the power distribution network on the basis of the analogy of the operation health condition of a complex power distribution network with the human health condition, builds a power distribution network health index assessment method model according to the model relation between the equipment health index and the fault rate
