T-connection intensive drawing and automatic modeling method

Abstract

The invention provides a T-connection intensive drawing and automatic modeling method for relevant wires in a power dispatching automation system (EMS). The T-connection intensive drawing and automatic modeling method includes drawing T-connection wires by a connection diagram drawing tool of the EMS system, automatically adjusting relation of serial numbers of connecting points T1 and T2 according to mutual connection relation of devices to generate T-connection station modeling files, transmitting the same to a maintenance service side, decomposing the T-connection station modeling files into substation modeling files by the maintenance service side and automatically modeling; modeling the relation of layers of the devices in the T1 station and the T2 station and relevant measuring points of the device in a tree moving mode during T-node modeling and device renaming operation.

Description

technical field [0001] This method involves the realization of power system plant station diagram drawing and automatic modeling. Using this method, grid dispatching automation maintenance personnel can realize the maintenance and modeling of T wiring diagram intuitively, and reduce the possibility of errors in the drawing and modeling process , improve system maintenance efficiency. Background technique [0002] The drawing and modeling of T-connection was mostly implemented in the drawing tool by establishing multiple T-connection diagrams. When modeling each T-connection diagram, corresponding multiple T-connection stations will be established. For example, establish plant and station diagrams of T1 station and T2 station respectively in the drawing tool. When drawing the T wiring diagram, use connecting lines to connect each single-ended line. [0003] If the T connection only involves one T contact, only T1 station will be used for drawing; but if the T connection onl...

Problems solved by technology

[0004] In this drawing method, due to the existence of two plant diagrams of T1 station and T2 station, as well as the connection line between T1 station and T2 station, the connection relationship of T connection cannot be clearly expressed, especially when the T contact exceeds When there are more than 2, it is difficult to intuitively understand the relationship between each T connection, and the connection parameters of the connection line between T1 and T2 stations cannot be expressed, which brings great inconvenience to the maintenance of the T connection station, and may also cause T Wiring modeling errors affect the accuracy of the power grid model and affect the actual dispatching and operation work
