Embodiment Construction
[0018] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0019] Such as figure 1 Shown is a logical block diagram of the steps of the embodiment of the present invention. An improved method for automatically generating power flow diagrams of large-scale transmission networks, including the following steps:
[0020] Step 1. Create substation graphics.
[0021] The substation is the basic container that constitutes the power system grid. There are primary equipment such as transformers, busbars, switches, and knife gates in the substation, as well as secondary measurement and control devices. The power lines connecting the substations are connected to the intervals inside the substations at both ends through terminals.
[0022] In view of this feature, in order to avoid the overlapping problem of the layout when there are multiple circuits between two substations, and to facilitate the automatic formation of...

The invention relates to an automatic generation method of a large-scale power transmission network tidal current diagram, which comprises the following steps of: establishing transformer substation primitives, and distributing all line terminals of a transformer substation to the peripheries of the transformer substation primitives; initializing the layout of the power transmission network as required; adopting a breadth-first algorithm topology to search for subnets, finding the subnets composed of substation primitives and power lines connected with the substation primitives, and connectingsubstations through the power lines; establishing a virtual connecting line between the substations to form a mapping model of nodes and edges, and automatically mapping; and carrying out regional division and sub-network layout on the power transmission network, and automatically generating a large-scale power transmission network tidal current diagram. On the basis of a traditional gravitationrepulsion algorithm, aiming at the characteristics of an electric power system, a new transformer substation graphic element is designed, the mapping logic is optimized, various required power transmission network tidal current diagrams can be automatically generated through the method, and the automatic mapping efficiency is improved.
Description
technical field [0001] The invention belongs to the technical field of power system automation, and in particular relates to a method for automatically generating a large-scale transmission network power flow diagram, which mainly solves the problem of automatically generating the power flow diagram of a large-scale power grid. Background technique [0002] The power flow diagram is used to represent the topological connection relationship between substations in the power system and the power transmitted on the network. The power flow diagram includes substation graphics elements, power line graphics entities, and connection lines that identify topological connection relationships. The connection line is a logical device that represents the connection relationship between the physical terminals of the power equipment, not the specific power equipment. [0003] The manual drawing of large-scale transmission network power flow diagram has a large workload and complex maintenan...
