specific Embodiment 1
[0023] The invention is a method for describing the power supply service range of a general distribution network public substation area, which includes the following steps:
[0024] Step 1, enter the address
[0025] Enter all user addresses in the station area, deduplicate the user addresses in the station area, and punctuate the remaining user addresses on the map;
[0027] The points at the left and right ends of the map are A(x 1 ,y 1 ), B(x 2 ,y 2 ); record the center point of the line connecting two points A and B as the origin O Take point O as the origin, horizontally to the right as the X-axis, and vertically upward as the Y-axis to establish a rectangular coordinate system;
[0029] Define the angle between the point on the map and the line connecting the origin and the X-axis counterclockwise as the arc angle α of the point; calculate the arc angle α of each point on the m...
specific Embodiment 2
[0035] Such as figure 1 As shown, the specific implementation process of a method for describing the power supply service range of the general distribution network public substation area includes the following steps:
[0036] Step 1: Enter the addresses of all users in the station area and remove the duplicate addresses of users in the station area, and the remaining user addresses are A(x 1 ,y 1 ), B(x 2 ,y 2 ), C(x 3 ,y 3 ),D(x 4 ,y 4 ),E(x 5 ,y 5 ), F(x 6 ,y 6 ), G(x 7 ,y 7 ), H(x 8 ,y 8 );
[0037] Step 2: Find the two points on the far left and the right, and record the leftmost point as A(x 1 ,y 1 ), and the far right is recorded as B(x 2 ,y 2 ), and the center point of the line connecting two points is denoted as O Take point O as the origin, horizontally to the right as the X-axis, and vertically upward as the Y-axis to establish a rectangular coordinate system;
[0038] Step 3: Define the angle between the point on the map and the line connecting...

Abstract
The invention discloses a method for depicting power supply service scopes of general distribution network public variable table areas. The method comprises the following steps of: de-weighting and punctuating user addresses in a table area; establishing a coordinate system by taking a central point O of a line formed by two points A and B at the left and right ends on a map through connection; defining a radianangle alpha, calculating an radianangle alpha of each point on the map, deleting the repeated points, anticlockwise connecting all the points on the map to form a plurality of anglesby taking the rightmost point B as a start point, and deleting the points of the angles which are smaller than Pi / 2; and anticlockwise connecting the residual points in sequence by taking the rightmost point B as a start point so as to form an area which serves as a power supply service scope of the table area. According to the method, user addresses are marked on maps in a longitude / latitude manner, and covered points are removed through angle calculation, so that the problems that the visual description of power supply service scopes of general distribution network public variable table areas is difficult, the fault address positioning is high in workload and the intelligent level is relatively low are solved, artificial depiction is not required and the artificial workload can be effectively decreased.
Description
technical field [0001] The invention belongs to the field of station area positioning, and in particular relates to a method for describing the power supply service range of a general distribution network public transformerstation area. Background technique [0002] For a long time, the spatial display of the area (transformer) user range has been the focus and difficulty of power gridvisualization. A good description of the user range of the station area (transformer) will help the fault address of the station area (transformer) ( Transformer) positioning, providing guidance for emergency repair and maintenance. At present, there are problems in the description of the power supply service scope of the distribution network public substation area and the intelligent positioning of the distribution network fault: 1 How to reasonably define the outer boundary of the station area (transformer); 2 How to select the outer boundary based on the definition of the outer boundary of...
