The Design And Implementation Of Hainan Power Grid Fault Comprehensive Analysis Platform

At present,each substation basically has the optical fiber communication conditions[1].However,due to the increasingly serious problem of global warming,the complex fault of power system is more frequent when Hainan Island lands in strong typhoon,which puts forward higher requirements for the rapidity and accuracy of power grid fault analysis.The previous fault analysis platform has not been able to meet the requirements,so it is urgent to build a platform that can analyze the complex fault of power grid quickly and accurately.Based on the actual demand,this paper has built and developed a comprehensive analysis platform for complex fault of Hainan power grid.Aiming at the fault data,it has broken through the problem of organic integration of fault information,realized the function of coaxial display,fault location,intelligent alarm,real-time call and automatic generation of fault analysis report for all fault data,and solved the difficulty and tediousness of fault analysis process,Troubleshooting the problem of confused thinking and trouble operation.The main work of this article includes the following aspects:First of all,the analysis of the recorded data,Baoxin substation and traveling wave data is completed.The oscilloscope data is acquired by the oscilloscope device in the substation,and converted into a common format file COMTRADE through data exchange;using the xml format and the credit system to realize data interaction,data analysis,comparison and storage,and regular transmission through SFTP To the server designated by the grid fault comprehensive analysis platform;combining traveling wave ranging and impedance method ranging,using wavelet transform to find the reflected traveling wave head within a certain range,and accurately positioning based on the initial traveling wave and reflected traveling wave.Secondly,the data integration technology is used to integrate all kinds of fault data,which are physically dispersed,logically.Through the relationship between them,a fusion model is formed,and finally a unified general object model system is formed to effectively complete the data analysis work.Thirdly,it analyzes the current situation of State Grid dispatching,and makes a detailed investigation on the data display mode of the recording and Baoxin sub station.it analyzes the actual needs and business processes of the staff of Hainan power grid dispatching department,which need to improve the overall level of state pre inspection and repair,real-time monitor the abnormal information of the equipment,such as self inspection exception,communication exception,clock exception,etc.,eliminate the hidden trouble in time,increase the equipment management ability,and reduce the frequency of accidents.Fourthly,it breaks through a series of difficult problems,such as:the server acquisition program needs to adapt to the access of multiple manufacturers and different types of recorders,the fault-tolerant processing when making data interface with the credit guarantee system,and the compatibility with the specifications of the Southern Network on the basis of the national network specifications.Finally,according to the actual application requirements of Hainan power grid,the software engineering idea is used to analyze the requirements,architecture design,detailed design,database design and interface design.During this period,using the database jfinal+Guice,Vue+Element,JavaScript and other technologies have realized the operation overview,station information,fault management,historical query,real-time access,system management and other functional modules.The most important thing is that in these functional modules,the coaxial display,fault location,intelligent alarm,real-time call and automatic generation of fault analysis report of all fault data have been innovatively realized.This function provides Hainan power grid dispatching department has strong technical and decision support,and completed the test.
