Theoretical study on dynamic capacity-increase of transmission lines

摘要

An online dynamic capacity-increase technology of transmission lines is designed by author to increase transmission capacity of transmission lines with no breach of available rules. The transient running formula of transmission lines is built, the mathematical relationship between the conductor allowable temperature and the variety of sag of the span is presented, and the effect of environment parameters on the transmission capacity of lines is analyzed, such as ambient temperature, wind speed, sunshine intensity, etc.
