Design Of Fixed Value Logic Correction System For User-level Relay Protection

With the rapid development of my country’s economy,as an important factor in ensuring productivity,the safe operation of power systems is becoming increasingly important.Relay protection,as the basis for the safe operation of power systems,also needs to meet the pace of the times.Therefore,it is very meaningful to conduct more research on the current relay protection fixed correction technology.This article designs the logical correction software of relay protection fixed value to solve the lack of professional and professional software for users.There are a large number of inspection of the work of the school check.In response to the problems with more protection values,the KMP matching algorithm with a faster matching speed is selected.Since the KMP can solve the problem of long retrospective time in the matching process,it can quickly match the inconsistent protection fixed value items,and then will then will be subsequently.Matching inconsistent fixed-value items uses expert systems to analyze.Revital protection fixed-value logic correction knowledge is to expand the knowledge base of the expert system.Finally,the analysis results of the expert system will be provided to users in a visual way.The main research work of this article is summarized as follows:First of all,the research background and significance of the topic are introduced,and the current status of relay protection in the power industry and the importance of the school nucleation of relay protection values on the safe operation of the power system.Secondly,the development process of the Revolutionary Protection Correcting System and the current status of research at home and abroad have been introduced,and some of the protective correction software that combines artificial intelligence is combined with artificial intelligence.Essence The general types of the text matching algorithm and the advantages of the KMP algorithm in this design were studied,and then the matching process of the KMP algorithm was analyzed in detail,the structure and function of the expert system were analyzed,the design was formulated this design.The design principles of the expert system,the selection of development tools,and the design of the inference machine.Finally,the sub-righteousness of the expert system fixed value was developed,and the specific implementation of the ultimate in the visual software was explained.The value items are reasonable through the expert system and given the corresponding conclusion.Users can determine the problems of the existing value according to the conclusion,solve the problems in the actual school nuclear of the site protection fixed value,and finally verify the logic of the relay protection fixed value logic.The accuracy and practicality of the correction system design.
