Abstract

In conventional power flow calculation, the lines resistances are always assumed to be invariable, which does not conform to the actual. Resistances of transmission lines are changed with changes of external environment and power distribution. In this paper, a model of power flow calculation considering temperature is presented. Temperatures and resistances of branches are linked with the modified power flow equations in this model. At the same time, the maximum current-carrying capacity is also analyzed and temperature can be gained by the algorithm to detect current. Through two kinds of power flow algorithm are compared and analyzed, the results show temperature of conductor has a very significant impact on the power flow calculation which should be paid attention to.
