In this scenario, an image showing the power flow condition of the target grid section may be generated as a target power flow map of the target grid section according to the power flow value and the corresponding power flow direction of the target grid line.

Further, based on a visualization technology of the GIS map in the related technology, the target power flow diagram of the target power grid section is subjected to visualization processing, and further the visual display of the target power flow diagram of the target power grid section is realized.

s201, obtaining section arc line nodes on the GIS map, and obtaining the power grid section arc line on the GIS map according to all the section arc line nodes.

In the embodiment of the application, the arc line of the power grid section can be drawn on the GIS map, so that the target power grid section on the GIS map is obtained.

Alternatively, the coordinates of the two end points of the grid section arc on the GIS map may be determined, and the coordinates of the middle point of the grid section arc may be determined according to the coordinates of the two end points.

The two end points of the grid section arc line on the GIS map and the respective end point coordinates of the two end points can be determined in advance, and the midpoint coordinates of the grid section arc line are determined according to the respective end point coordinates of the two end points.

Alternatively, a first abscissa and a first ordinate of a first end point of the grid section arc and a second abscissa and a second ordinate of a second end point of the grid section arc may be obtained.

In the embodiment of the application, the GIS map has a corresponding coordinate system, and the positions of the two endpoints of the power grid section arc line can be determined on the GIS map based on the coordinate system, so that the endpoint coordinates of the two endpoints are obtained.

Wherein one of the endpoints of the grid section arc may be identified as a first endpoint and the other endpoint as a second endpoint.

As an example, as shown in fig. 3, points a and B are two endpoints of the grid section arc shown in fig. 3 on the GIS map, where point a may be identified as a first endpoint, point B may be identified as a second endpoint, and the following is setThe endpoint coordinates of the point a are (X _A ，Y _A ) The endpoint coordinates of point B are (X _B ，Y _B ) X can be then _A Identified as the first abscissa, Y _A Identified as the first ordinate, X _B Marked as the second abscissa, Y _B Identified as the second ordinate.

Further, a midpoint coordinate of the grid section arc is determined based on the first abscissa and the first ordinate of the first endpoint, and the second abscissa and the second ordinate of the second endpoint.

As one possible implementation, in response to the first ordinate being the same as the second ordinate, a midpoint coordinate of the grid section arc is determined according to a first formula.

As an example, as shown in fig. 3, at a first ordinate Y _A And a second ordinate Y _B In the same scenario, the midpoint coordinates of the point C of the midpoint of the grid section arc shown in fig. 3 may be calculated according to the first formula.

Wherein the midpoint coordinates (X _C ，Y _C ) The first formula of (2) is as follows:

as another possible implementation, the midpoint coordinates of the grid section arc are determined according to a second formula in response to the first abscissa being the same as the second abscissa and the first ordinate being different from the second ordinate.

As an example, as shown in fig. 3, at a first abscissa X _A With a second abscissa X _B Identical and first ordinate Y _A And a second ordinate Y _B In a different scenario, the midpoint coordinates of the point C of the midpoint of the grid section arc shown in fig. 3 may be calculated according to a second formula.

Wherein, the middle of the point C is acquiredPoint coordinates (X) _C ，Y _C ) The second formula of (2) is as follows:

as another possible implementation, the midpoint coordinate of the grid section arc is determined according to a third formula in response to the first abscissa being different from the second abscissa and the first ordinate being different from the second ordinate.

As an example, as shown in fig. 3, at a first abscissa X _A With a second abscissa X _B Different and first ordinate Y _A And a second ordinate Y _B In a different scenario, the midpoint coordinates of the point C of the midpoint of the grid section arc shown in fig. 3 may be calculated according to a third formula.

Wherein the midpoint coordinates (X _C ，Y _C ) The third formula of (2) is as follows:

optionally, determining the node coordinates of the section arc node of the grid section arc according to the end point coordinates and the middle point coordinates.

In this embodiment of the present application, the grid section arc may be formed by a plurality of line segments, where points at two ends of each line segment may be identified as a section arc node of the grid section arc.

In the scene, the position of the section arc node on the GIS map can be obtained, wherein the coordinate of the section arc endpoint in the coordinate system corresponding to the GIS map can be determined as the node coordinate.

Optionally, the node number of the section arc node can be obtained, and the node ordering identifier of the section arc node can be determined according to the node number.

The node quantity of the section arc nodes included in the power grid section arc can be preset, and then node sequencing identification of each section arc node in all section arc nodes is determined according to the preset node quantity.

For example, if the line segments forming the section arc of the power grid are set to be 30, the number of nodes of the section arc nodes included in the section arc of the power grid is set to be 31, on the basis of fig. 3, all the section arc nodes are set to be ordered from the point a to the point B, the node ordering identifier of the section arc node corresponding to the first line segment is set to be 1, the node ordering identifiers of the section arc nodes corresponding to the adjacent second line segment can be 2 and 3 respectively, and so on.

Optionally, the node coordinates of the section arc node are determined according to the endpoint coordinates, the midpoint coordinates and the node ordering identifier.

As an example, if the number of nodes of the section arc nodes included in the section arc of the power grid is set to be 31 and the node sequence of the section arc nodes is set to be n, the following formula can be adopted, and the endpoint coordinates of the point a are set to be (X _A ，Y _A ) The endpoint coordinates of point B are (X _B ，Y _B ) Midpoint coordinates of point C (X _C ，Y _C ) And node ordering identifier n, determining node coordinates (X) of the section arc node corresponding to the node ordering identifier n _n ，Y _n ) Wherein the formula is as follows:

further, all section arc nodes are sequentially connected according to the node coordinates, and the power grid section arc on the GIS map is obtained.

In this embodiment of the present application, after determining the node coordinates of each section arc node, all section arc nodes may be connected according to a preset sequence, and a line obtained after connection is determined as a power grid section arc on a GIS map.

S202, acquiring target line intersection points intersecting with the power grid section arc lines in all lines of the GIS map.

In the embodiment of the application, the intersecting lines of all lines on the GIS map and the grid section arc line can be obtained, and the intersecting points of the intersecting lines and the grid section arc line are determined as target line intersecting points.

In some implementations, the coordinate sequences of all lines on the GIS map can be obtained according to the coordinate system corresponding to the GIS map, the coordinate sequences corresponding to the grid section arcs are compared, the lines with the same coordinates in the coordinate sequences corresponding to the grid section arcs are screened from the coordinate sequences of all lines on the GIS map, and the lines are determined to be intersecting lines intersecting the grid section arcs in all lines of the GIS map.

Further, the point corresponding to the same coordinate is determined as a target line intersection point intersecting with the grid section arc line in all lines of the GIS map.

In other implementations, the coordinate sequences of all the lines on the GIS map and the coordinate sequences corresponding to the grid section arcs can be processed according to a set algorithm, so that intersecting lines intersecting the grid section arcs in all the lines can be identified.

As an example, a certain line on the GIS map is set to be P1-P2, the grid section arc is set to be Q1-Q2, wherein P1 and P2 are two endpoints of the line, and Q1 and Q2 are two endpoints of the grid section arc.

Then it may be determined whether the lines P1-P2 intersect the grid section arcs Q1-Q2 based on the following formula:

(P ₁ -Q ₁ )×(Q ₂ -Q ₁ )×(Q ₂ -Q ₁ )×(P ₂ -Q ₁ )≥0

(Q ₁ -P ₁ )×(P ₂ -P ₁ )×(P ₂ -P ₁ )×(Q ₂ -P ₁ )≥0

When the lines P1-P2 and the power grid section arcs Q1-Q2 meet the two formulas at the same time, the lines P1-P2 and the power grid section arcs Q1-Q2 can be judged to be intersected, and the lines P1-P2 are intersected lines on a GIS map and intersected with the power grid section arcs Q1-Q2.

Further, according to the coordinate sequences of the lines P1-P2 and the power grid section arcs Q1-Q2 on the GIS map, the target line intersection point where the lines P1-P2 and the power grid section arcs Q1-Q2 intersect is determined.

S203, determining a section of the target line intersection point on the power grid section arc on the GIS map as a target power grid section of the GIS map.

It can be understood that each target line intersection point on the arc line of the power grid section has a corresponding tangent plane on the GIS map, and in this scenario, the tangent plane corresponding to each target line intersection point can be used as the target power grid section of the GIS map.

According to the visualization method for the power flow graph, the section arc line nodes on the GIS map are obtained, the power grid section arc line on the GIS map is obtained according to all the section arc line nodes, further, the target line intersection point intersecting with the power grid section arc line in all lines of the GIS map is obtained, and the tangent plane of the target line intersection point on the GIS map is determined to be the target power grid section. According to the method and the device, the target power grid section of the GIS map is obtained by drawing the power grid section arc line, visual display of a plurality of grid lines on the target power grid end is achieved, further, support is provided for visual display of the power flow condition of the target grid lines on the target power grid section, and the display precision and effect of the power flow parameters of the GIS map are optimized.

In the above embodiment, regarding the acquisition of the target grid lines on the target grid section by the GIS map, it can be further understood with reference to fig. 4, and fig. 4 is a schematic diagram of a visualization method of a power flow chart according to another embodiment of the present application, as shown in fig. 4, where the method includes:

s401, acquiring intersecting lines of all lines on the GIS map and the grid section arc line.

For specific information of S401, reference may be made to the related content in the above embodiment, and details are not described here.

S402, determining a target intersecting line which participates in section analysis in the intersecting lines, and acquiring a target grid frame line of the GIS map on the section of the target power grid according to the target intersecting line.

In the embodiment of the present application, in an intersecting line where all lines of the GIS map intersect with the grid section arc, there may be a section analysis where part of the lines do not participate in the target grid section of the GIS map.

In the scene, the lines which participate in the section analysis of the target power grid section are determined in all the intersecting lines, the lines are determined to be target intersecting lines, and the target grid frame lines of the GIS map on the target power grid section are obtained according to the display lines of the target intersecting lines on the target power grid section.

It should be noted that, after the target grid frame line on the target grid section is determined, the target grid frame line can be adjusted based on the subsequent section analysis requirement, which can be understood that if the subsequent section analysis requires adding and/or deleting part of the target grid frame line, the target grid frame line on the target grid section can be adjusted and updated based on the specific requirement.

S403, acquiring the total power flow value of the target grid line.

Optionally, line power grid data of each target grid line on the GIS map can be obtained, and according to the line power grid data, respective target power flow values of the target grid lines are obtained from a tide calculation database corresponding to the GIS map.

In the embodiment of the application, the line power grid database of the GIS map and the tide calculation database obtained by tide calculation can be stored separately, wherein the line power grid database stores related information such as line elements and dimensions of the GIS map, and related record information such as a factory station information table and a line information table can be defined by adopting E language symbol rules, so that the storage of the space and topological relation of all lines of the GIS map is realized.

Correspondingly, after carrying out power flow calculation on the GIS map, a corresponding power flow calculation database can be obtained, wherein the power flow calculation database stores line component information of the GIS map and related information of a power flow calculation result, and related information such as an alternating current node calculation result data table (< PSDPFEACNODE >), an alternating current line calculation result data table (< PSDPFEACLINE >), a direct current node calculation result data table (< PSDPFEDCNODE >), a direct current line calculation result data table (< PSDPFEDCLINE >) and the like can be defined by adopting E language symbol rules.

The power flow calculation database is provided with a field for recording the power flow related parameters of the line of the GIS map.

Alternatively, a mapping relationship between the first line element identifier in the line grid database of the GIS map and the second line element identifier in the tide calculation database may be obtained.

In some implementations, a mapping relationship exists between a first line element identifier in a line power grid database of the GIS map and a second line element identifier in the tide calculation database, wherein identifiers with the same combination key value in the first line element identifier and the second line element identifier can be determined to be line element identifiers with the mapping relationship, and then the mapping relationship between the first line element identifier in the line power grid database of the GIS map and the second line element identifier in the tide calculation database is obtained.

The first line element identifier of the line power grid database and the second line element identifier of the power flow calculation database each store the same part of line element identifiers, and may include a line element identifier corresponding to an I-side bus name, a line element identifier corresponding to an I-side reference voltage, a line element identifier corresponding to a J-side bus name, a line element identifier corresponding to a J-side reference voltage, a line element identifier corresponding to a parallel loop identifier, and the like.

In this scenario, a mapping relationship between a first line element identifier in a line power grid database of the GIS map and a second line element identifier in a tide calculation database may be constructed according to the partially identical line element identifiers.

Optionally, the related information of the first circuit element identifier corresponding to the ac circuit table in the line power grid database may be as shown in the following table 5:
