Dynamic Rating Management of Overhead Transmission Lines Operating under Multiple Weather Conditions

Integration of a large number renewable systems produces line congestions, resulting in problem for distribution companies, since the lines are not capable transporting all energy that is generated. Both environmental and economic constraints do allow building new to manage from sources, so efforts have focus on existing facilities. Dynamic Rating Management (DRM) power one best options achieve an increase capacity lines. The practical application DRM, based standards IEEE (Std.738, 2012) CIGRE TB601 (Technical Brochure 601, 2014) , allows find several deficiencies related errors estimations. These encourage design procedure obtain high accuracy ampacity values. In case this paper, two methodologies been tested reduce estimation errors. use variation weather inputs. It demonstrated reduction conductor temperature calculation error has achieved and, consequently, error.
