This paper presents an improved failure mode and effect analysis for reliability evaluation of distribution network. By introducing the state factor of switch automation, the calculation formula of power supply reliability index of load point is modified, and the traditional consequence analysis method of fault mode is improved. Taking the test model of overhead lines as an example, the effectiveness of the improved method is verified, and the importance of distribution automation in the reliability improvement of distribution network power supply is affirmed, and the practical principle of terminal configuration is given in conjunction with the situation of distribution network in Anhui Province.
