Research On Feeder Automation Analysis Platform Based On LabVIEW

The realization of feeder automation can be more convenient to collect,store and deal with distribution automation information.It can improve the reliability of power supply,improve the efficiency of fault location,reduce the cycle of fault isolation and restore power supply,and can further improve the automation level of distribution network.At present,the feeder automation level in distribution network has a certain automation and modern feeder function after scientific development.However,the application software in the distribution main station is still not mature enough,and the programming process is cumbersome,which makes it difficult to expand the scale of the software and improve the function.Therefore,the paper improves the existing fault location algorithm,uses LabVIEW as the tool to develop the feeder automation analysis platform,and tests the operation function of the feeder automation analysis platform,providing a platform for the future improvement of the scientific research of feeder automation and decision-making.The work of this article is as follows.1.Research on data acquisition,transmission and storage technology,fault detection and location related technologies.2.Using the programming tools such as LabVIEW's own control,operation function and other programming tools,the design of the analysis platform is designed,and the database connection method is selected to make the database access.Finally,the data waveform display,the fault location processing,the front panel display fault location results,the write database and the database are realized in the distribution network.Data query and other functions.The reasonable layout of the front panel and program of each functional module in the analysis platform is made,and each subroutine is connected to a feeder automation function analysis platform,and the operation process of the whole software operation is expounded.3.expatiate the main contents of feeder automation analysis platform,and generalize the whole idea of application software design in the platform.The whole structure of the platform can be divided into data acquisition,line running status analysis,analysis of data waveform display,write database,database reading and fault location processing.The data source is to read the Simulink simulation data directly through MATLAB Script.4.The simple fault of the simple distribution network system and the complex distribution network system is simulated by MATLAB/Simulink.The simulation data is used to test and verify the functions of the software.In this paper,using LabVIEW to develop a feeder automation analysis platform,we can obtain data under various operating modes of different scale distribution networks,display on the front panel in waveform form,and write the system data into the database,which can indicate the fault of the distribution network to the operator and locate the fault in the distribution network.The application software of the analysis platform is tested by simulation.
