Abstract

The invention relates to a graph generation method and system based on a Canvas, and the method comprises the steps of carrying out the primitive drawing of an electrical configuration graph based on the Canvas, generating a graph file of the electrical configuration graph, carrying out the analysis and graph rendering of the graph file of the electrical configuration graph, and generating a static configuration graph and a dynamic configuration graph. According to the invention, basic electrical wiring diagram drawing display and data query functions are met, complete API functions for searching, classifying, selecting and modifying attributes of layers in the Canvas and various primitives in the layers are provided, and secondary development of application expansion and functions according to requirements of other services of a power system is supported.

Description

technical field [0001] The present invention relates to the technical field of power systems, in particular to a method and system for generating graphics based on Canvas. Background technique [0002] With the rapid development of the national economy, the scale of the power grid continues to expand, and the power system is becoming more and more complex and intelligent. Therefore, the requirements for power production and dispatch monitoring systems are also getting higher and higher. Using the power automation monitoring system to conduct online detection of power operation parameters, real-time fault analysis and processing, real-time control and scheduling of operating conditions, etc., has been used in the reliability, safety, economy and improvement of power intelligence in power production and power distribution scheduling. Comprehensive management level and other aspects have played an important role. [0003] The configuration graphics system is an essential subsy...
