Comparison of Wind Load on Transmission Lines Between Old Codes and New Load Code

    Abstract
  • ［Introduction］ The paper aims to find out whether the existing lines meet the requrements of new load code. And the ratio of design value of wind load between old codes and new code is discussed.
      Method  In this paper， different load factors of different codes were given and the wind load design values of typical 500 kV and 220 kV lines were calculated and compared.
      Result  The proportion of wind load design values calculated by different old codes to new load code were given.
      Conclusion  Our data suggest that some of the existing lines designed by old codes not meet the requirements of new load， and have low reliability， they should be reforcement or reconstruction.
