Prearranged outage rate measuring and calculating method based on multi-factor influence

The invention discloses a pre-arranged outage rate measuring and calculating method based on multi-factor influence, relates to the technical field of power distribution network reliability, considers influence factors of project investment, maintenance resources and non-power-outage operation capability, and specifically comprises the following steps: step 1, according to a power outage event table of historical years and power outage responsibility reasons, calculating a pre-arranged outage rate; counting pre-arranged outage rates of historical years respectively; and step 2, after the parameters of the historical year are obtained through calculation, influence factors of project investment, maintenance resources and non-power-cut operation capability are comprehensively considered, influence coefficients of various influence factors are quantified, and the pre-arranged outage rate of the current year is regenerated. According to the method, mathematical association of engineering investment, maintenance r
