Multi-Dimensional Fault Risk Model of Transmission Tower Based on Principal Component Analysis
In view of the lack of comprehensive failure risk assessment model due to the impact of ice,strong wind,rainfall and other factors on transmission line towers at the same time,a multi-dimensional comprehensive failure risk assessment model for transmission line towers is proposed based on the principal component analysis method,taking ice,strong wind,rainfall and other factors in the South-ern Power Grid as the influencing factors.Firstly,according to the characteristics of ice loading speed,a fault risk model of transmission towers with ice loading is designed.Secondly,based on the wind load model,a fault risk model of transmission towers caused by strong wind is proposed.Thirdly,combined with the meteorological characteristics of rainfall,the failure risk model of transmission tower caused by rainfall is given.Fourthly,on this basis,a multi-dimensional comprehensive risk modeling method for transmission towers based on principal component analysis is proposed.Finally,an actual transmission tower is taken as an example to verify the effective-ness of the proposed method.
