System for automatically generating single-wire tidal current diagram of large-screen power transmission network during power scheduling

Abstract

The invention provides a system for automatically generating a single-wire tidal current diagram of a large-screen power transmission network during power scheduling, which relates to the field of the automation of the power scheduling. At present, the single-wire tidal current diagram is mainly drawn artificially, but with the continuous increase of transformer stations and lines, the task of drawing a wiring diagram of the power transmission network with the help of manpower is more and more difficult, and a generated scheduling large-screen wiring diagram presents more and more crowded and disorder states and brings difficulties to scheduling operators to distinguish. The system comprises a data reading module, a data maintenance and management module, an electric power system resource query module, a diagram generation module, a diagram query module, a diagram output module and a system management module. The system fulfills the aim of automatically generating the single-wire tidal current diagram and solves the problems of low efficiency and easy errors caused by relying on manual diagram drawing for a long time.

Description

【Technical field】 [0001] The invention relates to the field of electric power dispatching automation, in particular to a system for automatically generating a single-line power flow diagram of a power dispatching large-screen transmission network. 【Background technique】 [0002] At present, dispatching large-screen transmission network single-line power flow diagram is the core application display of dispatching SCADA (grid real-time data acquisition and monitoring system) system or EMS (energy management system) system. Its clear, beautiful, uniform, clear trend direction, and reasonable single-line power flow diagram greatly improve the dispatcher's familiarity and cognition level with the operation of the power grid, and facilitate the dispatcher to quickly grasp the topology characteristics of the power grid and various real-time information of the power grid, and Effectively carry out information association and traceability to facilitate quick and accurate judgment and...

Problems solved by technology

[0003] At present, single-line power flow diagrams are mostly drawn manually, but with the continuous increase of substations and lines, the task of drawing transmission network wiring diagrams by manpower is becoming more and more difficult, and the large-screen wiring diagrams for dispatching are increasingly presented. The crowded and messy state makes it difficult for dispatchers to identify
