Abstract :
Comprehensive consider grid catastrophic accident is influenced by the uncertainties of weather, environment, and network topology, to establish grid introduced to reflect the economic factors of risk assessment models and a comprehensive index system. Determine the risk indicators of relative weight by Analytic Hierarchy Process, and the fuzzy simulation methods is applied to assess the risk of catastrophic chain fault accident on the grid, combined with the experience of the operating personnel, the harmful consequences and probability of a combination of risk value is helpful to the maintainer to make decisions.
