摘要
To effectively evaluate the impacts of external working condition and internal operating state on condition assessment for ultra-high voltage transmission lines, we quantitatively analyzed the fault probability of transmission line caused by various external factors using the Bayesian network. Using the complex network theory, we quantified the difference in importance of transmission lines by systemic geometrical parameters. Finally, on the basis of the idea of risk assessment, we proposed an integrated state evaluation model of transmission line based on the Bayesian network and the complex network theory. Further simulations prove that the proposed model performs well in recognizing the important transmission lines with high failure probability in power system. Compared with the condition assessment based on external condition information, the proposed model takes the internal operation information into consideration, hence it has better ability of real-time importance identification with higher calculation speed, which fulfills the demands of practical engineering. ©, 2015, Science Press.
