| Abstract: |
| In order to overcome the shortages of diagnostic method for distribution networks considering the reliability
assessment, this paper proposed a method based on power supply safety standards. It profoundly analyzed the
security standard of supply for urban power networks, and established quantitative indicators of load groups based
on different fault conditions. Then a method suitable for diagnostic evaluation of urban distribution networks in
China was given. In the method, “N-1” calibration analysis of the distribution network was conducted. Then the
results are compared with quantitative indicators of load groups on different conditions deriving the diagnostic
conclusions and the standard revision is discussed. The feasibility and accuracy of the method is finally verified in
the case study. |
