The invention relates to a transmission and transformation station overhead line ground distance evaluation method and device, and the method comprises the steps: obtaining a GIM file of a power transmission and transformation project, and carrying out the analysis of the GIM file, so as to obtain a corresponding three-dimensional design model and GIM project data; obtaining a verification range of the distance to ground of the overhead line of the transmission and transformation station; acquiring design parameters in the verification range from the GIM engineering data, wherein the design parameters comprise meteorological information, conductor information of a strain section and conductor attribute information; calculating the lowest sag point of the conductor of the strain section under each meteorological condition according to the design parameters; acquiring topographic data, and calculating the distance to ground of the lowest sag point of the wire under the current meteorological condition according to the topographic data; and when the distance to ground is greater than the standard distance to ground under the current meteorological condition, determining that the distance to ground of the overhead line of the power transmission and transformation station meets the requirement. The method simplifies the review process, and improves the review efficiency and accuracyof the engineering model.
Description
technical field [0001] The invention relates to the field of power transmission line design, in particular to a method and device for evaluating the ground distance of an overhead line of a transmission and transformation substation. Background technique [0002] With the development of the digital age, the construction of smart grid puts forward higher requirements for the construction of substation projects. Through the innovation of technical means, the supervision level of substation projects can be further improved to ensure the quality of construction, improve efficiency and reduce costs. main direction. [0003] At present, the evaluation method for the distance between the overhead line of the actual transmission and transformation substation is generally based on the elevation data of the overhead line of the transmission and transformation substation provided by the designer, combined with the CAD cross-sectional drawing of the two-dimensional design of the overhea...
