Embodiment Construction

[0022] The technical solution of the invention will be described in detail below in conjunction with the accompanying drawings.

[0023] This application proposes a "VL-AClnbrh" model to generalize and abstract the finest granular electrical model of the one-line diagram to generate a supporting logic diagram, as follows figure 1 The four steps shown are figure 2 The original 1:1 granularity one-line diagram is compressed to obtain image 3 The abstracted VL-AClnbrh model is shown.

[0024] Step 1, VL unit generation

[0025] Except substation, switch station, ring main unit, branch box, user power distribution room and other massive station equipment abstracted as VL objects, electrical zero-impedance branches and T contacts are abstracted as VL objects. Will figure 1 The 110kV Baibutai Substation and Hongshengyuan Phase I Switching Station are abstracted into VL1 and VL5 as station equipment; the branch connected in series with #13 contact switch and #13 contact switch ...

Abstract

The invention discloses a scheduling distribution network single-line sketch compression method, and belongs to the technical field of calculation, reckoning or counting. Aiming at the problem of how to compress and abstractly generate a network diagram model of a distribution network single-line sketch by a conventional distribution network single-line diagram electrical model, the invention provides a scheduling distribution network single-line sketch compression method, which comprises the following steps of: combining non-impedance branches into independent VL unit nodes, removing suspended feeder branches, and combining feeder sections of a head phase and a tail phase; abstracting a distribution network model into a simplified network sketch model, and compressing and abstracting excessive details in the model, that is, mapping from an electrical model to the network sketch model is realized, so that a foundation is laid for subsequent orthogonalization layout and wiring of a single-line sketch.

Description

technical field [0001] The invention relates to electric power automation engineering technology, in particular to a method for compressing a single-line diagram of a dispatching distribution network, and belongs to the technical field of calculation, calculation or counting. Background technique [0002] The single-line diagram of the conventional distribution network is arranged with reference to the geographical direction. The types of equipment are complete and well-marked, which can meet the positioning requirements of equipment inspection and emergency repair. The comparison of gender is not obvious, and the importance of contact, section and ordinary load switch is not obvious, which is not conducive to the dispatcher to identify the context and grasp the key points, and does not conform to the dispatcher's reading habits. Logic diagram, also known as the scheduling single-line diagram. [0003] The abstraction of the model is generally based on the node-edge undirec...
