Problems solved by technology

[0003] With the development of dispatching large-screen visualization, displaying a flat grid power flow diagram on a large screen can no longer meet the needs of dispatching. The main shortcomings are as follows: (1) The display form is single, which reduces the viewing experience of power grid dispatchers
(2) The amount of information is thin, and the dispatcher cannot directly see the important power flow data and key business indicators of the plant and station
(3) The function is single, and it can only monotonously display the line distribution and power flow distribution between plants and stations. There is no business refinement of the data, and it cannot reflect abnormal situations, such as user path tracing
(4) It is not interactive, which further reduces the information acquisition and use experience of power grid dispatchers

Embodiment Construction

[0035] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0036] refer to figure 1 , this embodiment includes the following steps:

[0037] (1) Obtain the CIM model and SVG graphic files of the D5000 (hereinafter referred to as D5000) at the master station of the intelligent dispatching technical support system;

[0038] CIM model refers to the public information model, which is an abstract model that describes all the main objects of electric power enterprises, especially the objects related to electric power operation; it is divided into two parts: CIM Specification and CIM Schema, including There are more than 14 logical packages, and CIM's classes contain keywords that uniquely identify object instances.

[0039] SVG graphics file refers to scalable vector graphics, which is an open standard vector graphics language based on XML (Extensible Markup Language).

[0040] (2) Automatically g...

Abstract

The invention relates to a three-dimensional grid automatic modeling method based on a CIM model and an SVG graph. The three-dimensional grid automatic modeling method comprises the following steps: (1) acquiring a CIM model and an SVG graphic file of a main station end D5000 of an intelligent dispatching technology support system; (2) automatically generating a three-dimensional grid according tothe SVG graphic file; (3) updating three-dimensional grid model parameters according to the CIM model; (4) correlating the three-dimensional grid model and acquiring real-time data; and (5) displaying an abnormal user power supply path. The method provided by the invention takes the CIM model and the SVG graphic file as a basis, the three-dimensional grid is automatically generated, and the method has multiple interaction functions and strong interaction capability.

Description

technical field [0001] The invention relates to an automatic modeling method for a three-dimensional grid, in particular to an automatic modeling method for a three-dimensional grid based on a CIM model and SVG graphics. Background technique [0002] EMS (Energy Management System) is a general term for modern grid dispatching automation systems (including hardware and software). Its main function consists of two parts: basic function and application function. Basic functions include computer, operating system and EMS support system. Application functions include data acquisition and monitoring (SCADA), automatic generation control (AGC) and planning, network application analysis. The power flow diagram in the EMS is a picture used by the power dispatching department to reflect the real-time operating status of the power system. In the desktop system, it centrally displays the distribution of lines between plants and stations and the distribution of power flow. It is the m...
