Problems solved by technology

[0006] At present, the maintenance of the connection relationship of power grid resources in the power distribution system is mainly done manually, so that the drawing personnel need to operate too many steps: when drawing a power grid equipment on the GIS map , in addition to spatial drawing operations and associated device attributes, it is also necessary to configure the connection relationship between the device and multiple grid devices. When deleting, it is also necessary to find out the connection relationship of the devices related to the deleted device, and re-maintain these relationships; traditional This method requires too many parameters to be configured when adding or modifying a power grid device on the GIS map, the steps are complicated, the requirements for the drawing personnel are too high, and it is easy to make mistakes

specific Embodiment approach

[0034] The technical solution of the present invention can adopt computer software technology to realize the automatic operation process. The present invention will be further described below in conjunction with the accompanying drawings and examples, but the following examples should not be construed as limiting the present invention. see Figure 4 , the flow process of the embodiment is as follows:

[0035] Step 1. Carry out spatial analysis on the spatial elements drawn on Arcgis to form the spatial connection relationship of the elements;

[0036] Calculate the spatial connection relationship according to the spatial position of the Arcgis element and the attribute of the line to which the element belongs, and calculate the sensitive threshold parameter of the space perception to process the connection error in the process of spatial graphics drawing, and enhance the effective connection area, so as to obtain the equipment resource. connection relationship.

Embodiment

[0091] The embodiment adopts the following two steps to realize:

[0092] Step 2.2.1, write the outlet node into the topology tree table, the filling method of the topology tree table in the embodiment: the parent connection point and the root connection point are 0; the node depth is 1; the parent node resource ID and the root node resource ID are disconnected in the station Connector resource ID; connection point: use the outgoing resource ID to find the connection point that has a terminal among all the connection points on the line (a terminal is a record).

[0093] In step 2.2.2, the outlet node connected to the circuit breaker is used as the starting point of the analysis, and written into the temporary analysis table tmp_currtermce. In this embodiment, the outgoing node connected to the circuit breaker is obtained by querying the records whose node depth is 1 in the table top_tree.

[0094] Step 2.3, add 1 to the node depth in memory.

[0095] In step 2.4, the currently...

Abstract

The invention discloses a generating method for a power grid topological relationship based on Arcgis. The generating method comprises a step of achieving generating a power grid resource space connecting relationship automatically based on an Arcgis space analysis, and a step of generating a network topological relationship based on a depth preferential search. The technical proposal provided bythe invention automatically maintains the power grid resource space connecting relationship based on a space connecting relationship of Arcgis elements and service attributes of the elements, and uses a depth preferential algorithm to quickly generate the network topological relationship according to the correct connecting relationship. The technical proposal solves the problems that the maintenances for the connecting relationship of devices in the power grid are complicated and a network topology of the power grid is reconstructed after the power grid changes. The technical proposal is usedto solve the applications such as power supply tracing, a power supply range, a power supply radius, a power failure imitation and the like in a city power distribution grid.
