摘要（英）：

The invention relates to the field of 35kV power distribution construction, in particular to an assessment method for 35/0.4kV rection station area protection equipment selection. The method comprises the following steps of: (1) confirming influencing factors of 35/0.4kV rection station area protection equipment selection in the 35kV power distribution construction; (2) providing a 35/0.4kV rection station area fuse wire sectionalized protection scheme; (3) confirming weights of the influencing factors of 35/0.4kV rection station area protection equipment selection, and establishing an analytic hierarchy process assessment model; (4) assessing 35/0.4kV rection station area protection equipment selection based on integration of power supply-power grid-load; and (5) completing the 35/0.4kV rection station area protection equipment selection. According to the assessment method for the 35/0.4kV rection station area protection equipment selection, the problem of contradictoriness of reliability and economical efficiency of the 35/0.4kV rection station area protection configuration in 35kV power distribution can be solved, and the reliability and economical efficiency of power supply in the 35kV power distribution construction can be effectively improved.
