Abstract
The invention discloses a kind of transmission line safety risk status appraisal procedure, include the following steps: to construct route danger source occurrence Probability Model Γ { T, α_{k}, k=1,2 ..., 12, β }, wherein route danger source occurrence Probability Model includes parameter danger Source Type T, leads to the line fault type β of danger source and each monthly probability of happening α in year_{k},k=1,2,...,12；Determine that the probability of happening E of a kind of failure occurs for section route_{1}:Determine that the probability of happening E of two class failures occurs for section route_{2}:Utilize the probability of happening E of a kind of failure_{1}With the probability of happening E of two class failures_{2}Determine the security risk state of route.A kind of advantages of the present invention: transmission line safety risk status appraisal procedure of the invention, combined circuit failure cost, which is realized, on the basis of establishing route risk source occurrence Probability Model assesses transmission line safety risk status, provides aid decision data to line inspection job placement by assessment result.
