Research On The Application Of Intelligent Dispatching Oriented Power Grid Fault Handling In Metropolis

With the rapid development of social economy,electric power as a national pillar industry is growing rapidly.Now,the power network structure is becoming more complex,and the amount of information collected and processed by the power dispatching control center is also increasing.The accompanying problem is how to carry out various businesses reliably,accurately and efficiently.Guangzhou power grid is a mega city power grid,which is the load center of South China and also the location of West to East power transmission.Its power supply reliability is extremely important.However,at present,the fault handling of Guangzhou dispatching is still in a fully artificial state,and an intelligent power grid fault analysis system is urgently needed.This paper will focus on the construction of the auxiliary support system for fault handling of the author’s department.The author expects to study the technology and application of power grid fault handling in combination with the working experience,so as to "learn for application".The main completed tasks include:(1)Investigated and analyzed the technical status of dispatching fault handling.Combined with the daily work responsibilities of the author and considering the actual work of the dispatcher,this paper analyzes a large number of practical cases of fault disposal,and puts forward the existing whole process framework of dispatching fault disposal.This paper also finds out the deficiencies in the existing work process,and determines it as the goal of the full text.(2)Following all kinds of rules and regulations,this paper attempts to combine the author’s working experience and understanding.According to the existing whole process framework,the paper studies the technical scheme of fault handling application for intelligent dispatching.It comes up with the general logic framework of the application,and then unfolds its internal core modules respectively and refines its operation form.(3)According to the actual work,the data interaction relationship of each system is used for the main data interaction involved in the internal core module.The data transmission format of each link is limited according to the actual needs,and finally forms the interface conditions for fault disposal application.(4)Combined with the actual work needs,the front-end interface of fault handling application is designed.At the same time,the final form of fault exception handling auxiliary support software is applied to the actual case.After comparing the result with the dispatcher’s handling method,the final conclusion can tell whether the operation is reliable.In order to solve the problems of low efficiency of message identification and complex interaction among multiple systems,the design scheme of fault handling support system is completed in this paper.This scheme has been effectively integrated into the ‘Dispatching robot’ project of the power dispatching control center of Guangzhou Power Supply Bureau,and effectively fits all kinds of systems used by dispatchers.It can greatly improve the work efficiency of dispatchers in case of power grid failure,and has good practical value and significance.
