Abstract

The invention relates to the technical field of overhead lines of a power distribution network, and discloses attitude display of a lead under different working conditions of the power distribution network. The attitude display comprising basic calculation parameters including temperature, wind speed, icing thickness, average wind speed height, reference height, attribute of the lead and information of an insulator chain under each working condition in a meteorological zone where a project is located. According to the attitude display of the lead under different working conditions of the distribution network, if the attitudes of the lead under various working conditions can be accurately calculated in real time according to a meteorological area where a line is located in operation management, a three-dimensional visualization technology is used for drawing a calculated lead model in real time, and three-dimensional visual display is performed by integrating a line corridor scene and related information; and problems can be easily found and pre-judged in the early design stage and the later operation and maintenance stage, accidents are avoided, accuracy, high efficiency and real-time performance can be achieved at any time, the state of the wire can be checked in real time in the design and operation and maintenance stages, and the calculation result can also be used for electrical safety distance verification and accident avoidance.

Description

technical field [0001] The invention relates to the technical field of distribution network overhead lines, in particular to a gesture display of a conductor under different working conditions of a distribution network. Background technique [0002] The overhead lines of the distribution network have the characteristics of long working distance, and the tower equipment is not only distributed in the wild environment, but also arranged in a large number of urban areas. The inspection and monitoring of power grids have always been difficult for power grid enterprises. In the operation management, if the posture of the conductors under various working conditions can be calculated in real time and accurately according to the weather zone where the line is located, and the calculated conductor model can be drawn in real time with 3D visualization technology , comprehensive line corridor scenes and related information are displayed in three dimensions, and problems can be easily f...
