It should be understood that the description is only illustrative and is not intended to limit the scope of the invention. In addition, in the following description, descriptions of well-known structures and techniques are omitted so as not to unnecessarily obscure the present invention.
The embodiment of the invention provides a regional division display method for an autonomous controllable new generation transformer substation. The method analyzes the system specification description SSD file, extracts node information and selects key node information of a geographic area.
The technical specification general series specification 8 of the secondary system of the autonomous controllable new generation transformer substation is that a transformer substation geographic area model is added on the basis of the DL/T1874 standard and is used for describing the geographic structure of a transformer substation and the association of equipment in the transformer substation with the geographic structure. The SSD file is an xml file, the area information of the SSD is composed of a plurality of node information in the xml file, and the definition of elements and attributes contained in the node information is the first definition in the technical Specification general series Specification 8 substation equipment information model of the secondary system of the independent controllable new generation substation, which is a new demand.
The technical specification general series specification 8 transformer substation equipment information model of the autonomous controllable new generation transformer substation secondary system defines geographical area models including an area model, a screen cabinet model, a physical equipment model and the like, wherein the area model comprises a surrounding wall, a switch field, a space place, a building, a floor, a room, a road, a cable duct and the like, and the specification specifically defines the following table 1 (the definition of each element and attribute of SSD geographical area information):
When the SSD file is analyzed, the information such as the geographical area node, the device equipment node, the cable connection node and the inclusion relation among the geographical area node information is extracted:
geographical area node information: wall, building, floor, room, switchArea, bayArea, road, ditch, door, otherArea, preCabinet, cabinet;
substation equipment model node information associated with a geographic structure: GENERALDEVICE, CONDUCTINGDEVICE, BOARD, PORT;
Cable connection node information: cable, cable Terminal, cableConnectivityNode;
the inclusion relationship between the geographical area node information includes:
For example, the Building may include a Floor, the Floor may include Room, the Room node may include Cabinet, door, or directly include the substation equipment model node information such as GENERALDEVICE, CUNDUCTINGDEVICE;
SWITCHAREA may contain BayArea, otherArea and road, bayArea may contain Cabinet or directly contain GENERALDEVICE, CUNDUCTINGDEVICE substation equipment model node information;
the Cabinet is Cabinet information and can contain GENERALDEVICE or CunductingDevice substation equipment model node information.
The Substation is taken as a root node, geographical area node information under the Substation node is classified, the classified nodes comprise root nodes and all levels of child nodes of the root nodes, 1 level root nodes comprise Building or Wall or SWITCHAREA,2 levels of child nodes comprise Floor or BayArea,3 levels of child nodes comprise Room and Cabinet, and 3 levels of child nodes comprise Cabinet.
In the display of the regional division of the transformer substation, namely the display of the geographical region information of the transformer substation in the SSD, the position of geographical region node information is only required to be displayed in the current specification, so that the geographical region node information is selected as key node information, a stack is required to be stored for later use, GENERALDEVICE or CunductingDevice nodes are primary equipment models, the relationship of the nodes in the SSD is used for reflecting the association relationship between the primary equipment reference and the geographical models, namely whether the association relationship between the regional information and the primary equipment is required to be established or not is represented, and the geographical region information only requires to be displayed to the minimum node level of a transformer substation screen cabinet and does not require to display the position relationship of the primary equipment, so GENERALDEVICE or CunductingDevice are not required to be displayed; the substation equipment model node information, the cable connection node information and the like do not need to be stored and displayed.
The invention extracts the containing relation among the geographical area node information when analyzing the SSD, and can quickly locate the child nodes and draw the graph of the child nodes and avoid missing the area information represented by the child nodes by straightening the containing relation when displaying the area division.
After the key node information of the geographical area is selected, the invention designs the drawing and displaying principle for displaying the geographical area information of the transformer substation.
Specifically based on the following 4 presentation principles:
1) Coordinate axis definition: the lower left point is the origin (0, 0); the vertical axis is the x axis, and the north is the positive direction; the horizontal axis is the y axis, and the direction east is the positive direction;
2) Northeast and northwest directions: north, south, west and east;
3) When the diagonal coordinate identifier rect is true, coordinates is the coordinate (x 1, y1: x2, y 2) represents a rectangular region, wherein (x 1, y 1) and (x 2, y 2) are two diagonal coordinates of a rectangle, and are displayed in a rectangle when displayed; when rect is false, the coordinates (A1, B1: A2, B2: A3, B3) of coordinates represent irregular areas, which are closed curves connected in sequence and connected end to end, wherein (A1, B1), (A2, B2) and (A3, B3) are coordinates of 3 points connected end to end. In the node information of the geographical area of the SSD, the combination of the spatial coordinate positions of the area is described, and the two coordinate positions are divided by a ':'. When the rect attribute is true, the number of the space coordinates is 2, two opposite angles of the rectangle are represented, and the format is (x 1, y1: x2, y 2); when the rect attribute is false, the number of the space coordinates > =3, which represents a closed curve with the space coordinates connected in sequence and connected end to end, and the format is (A1, B1: A2, B2: A3, B3).
4) The (x, y) in the region spatial position information attribute is the relative coordinates: the upper left point of the upper layer area above the lower layer area is the origin of the coordinate system; the Substation layer is the uppermost layer region, and the lower left dot coordinates are (0, 0).
The multi-floor display method is divided tab page display, namely if floor exists in the geographical area of the transformer substation, the top views of different floors are displayed in the form of multiple tab pages, namely the 1 st tab page displays the top view of the whole station 1 floor, the 2 nd tab page displays the top view of the whole station 2 floor, and so on, and the display effect is simple and clear.

After the coordinate format is checked successfully, continuing to the next step, otherwise, warning to prompt that the coordinate format is wrong and exiting the display;
recording node information of each geographical area under a subtstation node to a stack to acquire node information;
according to the node stack information, whether each node is mapped is confirmed, and the method is as follows:
