Abstract :
This paper discusses variation of the inductive reactance of ACSR conductors due to temperature. An estimate of this variation is presented. The 14-bus system is used to obtain an estimate of the effect of the expected reactance variation in the line flows. It is found that the average of the change in line currents is less is 3.6%, but the maximum change in a line is more than 14% in most cases. The average change in the reactive power flow is more than 21%.
