Method for temporarily changing power grid topological structure

Abstract

The invention discloses a method for temporarily changing a power grid topological structure. The method includes the steps that firstly, when temporal head detaching and head lapping are conducted on a transmission line and the connecting relation between a power grid topological structure and an element is changed, a broken line board is used as a mark symbol, and a broken line mark is displayed on a corresponding circuit; secondly, the mark position with the hung broken line board serves as a kind node, and a kind node database is established; finally, a conflict resolution strategy is introduced in. The method solves the problem that a graph dispatching operation system changes the connecting logic of the power grid structure and the element due to temporary work in practical work, so that an operation order system cannot work normally, and therefore the functions of the graph operation order system are improved.

Description

[0001] The patent application of the present invention is a divisional application of the invention title "Method for Temporarily Changing Power Grid Topology Structure in Graphical Scheduling Operation Ticket System". The original application date is January 4, 2013, and the application number is 2013100030695. technical field [0002] The invention relates to a method for changing the topological structure of a power grid in a graphic dispatching operation ticket system. Background technique [0003] After the topological analysis of the power grid topology in the current grid dispatching operation ticket system based on the graphical interface, the user (dispatcher) can manually change the status of the grid components (switches, switches, protection), but the grid components Between, especially the connection relationship between different plant components cannot be set and changed. [0004] In order to improve the reliability of power supply and minimize the scope of po...

Problems solved by technology

[0004] In order to improve the reliability of power supply and minimize the scope of power outages in the actual maintenance work of the power grid, the power grid structure is temporarily changed by means of dismantling and overlapping of lines. Inconsistencies appear in the topology of the power grid. At this time, functions such as graphical invoicing and anti-error verification cannot work normally due to errors in the topology relationship. And lost the safety check function

Moreover, due to the lack of indication of changes in line connection relationship, it is easy to cause misinvoicing, endanger the stability and reliability of the power grid and the safety of people, and cause greater social impact and economic losses.
