Problems solved by technology

[0003] In order to solve the problem that the method of recording fault data in the prior art can only present the change of sampling data, the separation and closing of the wave recording switch is hindered by the limited storage information, making the analysis of the wave recording unintuitive and inaccurate, the present invention provides A graphic instantiation method that adds two files .des and .mid to the original comtrade to store the protection logic of the device and the real-time status of logic components, and completes the inversion of fault recordings and intelligent analysis on this basis

Embodiment Construction

[0021] The present invention will be further described below in conjunction with the accompanying drawings.

[0022] A graphical instantiation method based on IEC61850 failure analysis system, characterized in that: comprising the following two steps:

[0023] 1. Multi-level logical configuration based on SVG

[0024] This system uses SVG format to store protection logic, supports basic elements such as rectangles, texts, and curves, and also supports element defines a custom primitive shape, The element identifies the hierarchical relationship of the primitive, through The element instantiates the primitive, defines the id attribute as the unique identifier of the logic element, and establishes the mapping between the primitive and the attribute of the logic element. Define the logic block diagram as shown in the figure, and use the following graphic metadata to represent:

Abstract

The invention discloses a graphic instantiation method based on an IEC61850 fault analysis system, and belongs to the technical field of automation of power systems. The method is characterized by comprising the following two steps of: (1) scalable vector graphics (SVG)-based multilevel logic configuration: configuring a protection implementing logic according to the protection principle, and configuring associated logic signals or logic algorithms in a logic component; and (2) intelligent analysis of fault recorder: transmitting and resolving the logic configuration of an SVG format, and displaying the logic component characteristics and the intelligent curve of a selected moment. By the method, the problems that analysis of recorded wave is not intuitive or accurate because the method for recording fault data can only represent the change of the sampled data and separation and combination of the wave recording switching quantity and the stored information is limited are solved; and the invention provides the graphic instantiation method for implementing inversion and intelligent analysis of the fault recorder by increasing two files, namely .des and .mid for storing the protected logic of a device and the real-time state of the logic component based on the conventional comtrade.

Description

technical field [0001] The invention belongs to the technical field of power system automation, in particular to a graph instantiation method based on an IEC61850 fault analysis system. Background technique [0002] At present, the method of recording fault data in China is comtrade recording of three files. Through these three files, the action of relay protection and high-voltage circuit breaker is analyzed, and the exact location, development process and Fault type, in order to quickly troubleshoot and formulate preventive measures. The fault recording file in COMTRADE format includes three parts of information: *.dat data file, which records the value of each input channel of each sample in the transient data in binary form; *.cfg configuration file, which provides a reasonable explanation of the data file (*.dat) required information and *.hdr information files. Although the existing fault analysis software based on these three files can reproduce the fault data in th...
