Abstract

A comprehensive reliability assessment model for transmission grid under lightning is proposed.Transmission line is segmented according to the lightning grades.Reliability model of substation is established according to the principle of statistics and the guidance of high voltage insulation coordination.The complex network theory is utilized for the weights setting of reliability indexes.A real high voltage transmission grid is taken for example to demonstrate the feasib ility of the proposed reliability evaluation model.The sensitivity of the relationship between the weight coefficients and the system reliability under lightning is also analyzed.In addition

some suggestions for lightning protection of power systems are offered.
