Abstract

The invention relates to a method for determining an inlet-outlet line investment contour line for site selection of a proposed substation and an application manner. The method comprises the following steps of: inputting the final positions, line attributes, buckling factors, unit costs and other parameters of inlet-outlet lines of all voltage grades as well as the geographical range for site selection of the substation in a human-machine interaction manner; calculating the total investment of all the inlet-outlet lines at all points of the substation in the range by a computer; connecting points with the same investment on a plane by a curve to form a closed or non-closed line; drawing one line every one investment difference according to a set difference value; and marking the line like marking the contour line of a topographic map.

Description

technical field [0001] The invention belongs to a method for optimizing the site selection investment of a substation in power grid construction, in particular to investment evaluation and optimal site selection carried out by applying the investment contour method of the incoming and outgoing lines of the substation. Background technique [0002] The definition of "contour line" is "a line connecting certain geographical objects or phenomena with equal values", "a line connecting points with equal values ​​of meteorological elements on a certain reference plane", etc. According to the results published by the "National Committee for Approval of Terms in Science and Technology", the applied disciplines of "isoline" are "geophysics", "geographic information system" and "atmospheric science", and the English names are contour line, isarithmic line and isoline, etc. ; No engineering instructions. The "contour" of the present invention is an extension of this concept in enginee...
