Problems solved by technology

[0006] The analysis algorithm based on the protection action chain is a fast power system fault analysis method. Its core logic is to collect action events reflecting the same fault area in a certain period of time and form a protection action sequence in chronological order, which is called Protect the action chain, and then use the local topology and protection trip logic to analyze the trip coverage of each protection ac

Embodiment Construction

[0052] The overall structure of the system is shown in figure 1 As shown, it is mainly divided into modules such as signal acquisition, diagnosis and startup judgment, fault analysis, fault report generation, and comprehensive display of analysis results; the core module of the rapid fault analysis system is the fault analysis logic based on different algorithms. The rapid fault analysis system can combine the characteristics and scale of the problem to manually or automatically switch various analysis modules to give the optimal fault analysis result. Here the fault analysis module is: an analysis module based on integer programming.

[0054] Organized data is good data. "At the substation side, through the human-machine interface, the alarm information collected at the substation level is displayed in a hierarchical and classified manner based on priority. Without manual processing, the alarm information of the current period is displa...

Abstract

The invention relates to an intelligent warning system based on integer programming. The intelligent warning system adopts a signal acquisition module, a diagnostic startup judgment module, a fault analysis module, a failure report generating module and an analytical result comprehensive display module to warn; the intelligent warning system can be implemented through the following steps of: 1) network modelling, filling primary equipment of a transformer substation and a connected relation of the transformer substation into a database; and generating a structural model meeting IEC (international electrotechnical commission) 61970 standard of an electric system factory station and a system, and then using the model to generate a network device library through a filling library operation; 2) protected information modeling: carrying out protected information modeling according to the hierarchical relationship of the primary equipment, a protective device, protected information and a trip breaker, building an incidence relation between a protection main device, the protected information and a breaker motion, and protecting the main device namely the primary equipment; and 3) carrying out fault diagnosis. The intelligent warning system in the invention can be capable of rapidly and effectively carrying out detailed analysis on a single or complicated failure and protection motion analysis in a failure process.

Description

technical field [0001] The invention relates to an intelligent alarm system for an intelligent substation. Background technique [0002] With the rapid development of science and technology, the degree of automation of substations is getting higher and higher, and the amount of information is also increasing; the abundance of information is bound to bring great help to data analysis, but this has also become a double-edged sword. On the back of the double-edged sword, there are "smashing flowers and charming eyes", that is, the visual and psychological impact of massive information on the operation personnel on duty in a short period of time. The new signal is annihilated, and it is difficult for the operator on duty to quickly grasp the key points, which is not conducive to quickly judging the fault and giving a correct judgment. [0003] With the advancement of grid intelligence, the intelligent technology of substations has gradually become an important part of smart gri...
