Abstract

The line transmission current capacity will directly affect the level of power generation and electricity

so how to improve the line transmission current capacity should be widespread concern on.Because of the high cost of measurement and it is difficult to guarantee the reliability for sunshine which will be used to identify for calculation the transmission line current capacity

makes the dynamic calculation of transmission line carrying capacity difficult to be wildly used.This paper proposes a method which take the line temperature and current as input and output of a dynamic system and the information will be used to identify the parameters of sunshine.The method proved effectively to predict the online maximum current carrying capacity and provided a reference in order to take full advantage of the line transmission capacity and to ensure the power supply reliability.
