Embodiment 1

[0015] The present invention will be further described below in conjunction with specific implementation examples.

[0016] 1) Set the granularity filtering conditions of the map, set the plant type to substations and switchgears with a voltage level of 10kV~220kV, and select the type of measurement to mark A-phase current, active power, and reactive power. Search out the qualified plant station and line information from the current power grid model, generate plant station graphics and line graphics elements in the deployment system drawing tool, each plant station graphic element is evenly distributed, and generate line graphics elements between connected plants and stations to connect.

[0017] 2) Use the network topology map layout algorithm based on the extended mechanical model for the intelligent layout of the station graphics, which is an improved algorithm based on the repulsion-tension model algorithm;

[0018] The network topology graph in the network topology graph...

Abstract

The invention discloses an implement method for automatic generation of a visible power grid trend chart in a dispatching system. The method comprises the following steps: (1) according to set chart forming granularity filter conditions, station pels and circuit pels are generated in a picture through a drawing tool of the dispatching system; (2) intelligent layout is conducted to the station pels through a network topological graph arithmetic based on an expanding mechanical model; (3) intelligent wiring is conducted to the picture after the intelligent layout by using a maze arithmetic; (4) a parameter in a bank is related automatically and labels such as measurement, a dynamic trend and a visible pie chart are conducted automatically, and the visible power grid trend chart is generated finally. According to the implement method for automatic generation of the visible power grid trend chart in the dispatching system, the visible power grid trend chart needed by the dispatching system can be generated rapidly, so that powerful technical support is provided to implement of the dispatching system and power grid analytical research. Due to intelligent and automatic chart forming process, efficiency is improved, omissions caused by human factors are greatly reduced and technical guarantee is provided to safe and stably running of a power grid.

Description

technical field [0001] The invention relates to a realization method for automatically generating a visualized power flow diagram in a distribution system. Background technique [0002] In the power grid deployment monitoring system, monitoring and adjusting the distribution of power system power flow is an important responsibility of the modern power dispatch automation system. Power system operation dispatchers need to closely monitor and adjust the distribution of power grid power flow at any time. , An essential part of system analysis research. In the current monitoring system, drawing power system network topology diagrams and power grid flow diagrams is manually drawn by maintenance personnel or engineers using dispatching system drawing tools based on the actual topology of the monitored power grid, and based on physical wiring. Graphics are used to describe the network structure of the power system, data is marked on the graphics, and data and graphics are combined...
