Research On Multi-source Data Acquisition System Of Distribution Network Based On ROA Architecture

With the continuous development of distribution network information construction,the distribution of information related to the field of information is also more and more,these data not only contains the grid voltage,current and other operational information,including geography,weather and other related information,Through the collection and storage of these data and effective management can improve the overall monitoring of the distribution network ca pacity,and for the distribution network of various applications to provide reliable and stable data support.Because of the wide variety of data sources of distribution network,including SCADA,PMU,power quality monitoring system data,different data re quirements and application scenarios are different,in the data format,accuracy and other aspects are A big difference.At the same time,these heterogeneous multi-source data still exist data redundancy,missing and abnormal situation.In addition,the d istribution network data acquisition system is also facing a wide range of plant distribution,communication protocol a wide range of terminal collection equipment and other characteristics.The above characteristics constrains the application of distribut ion network,making it difficult for each distribution application to support each other.In this paper,the source of large data of distribution network is analyzed,and the basic characteristics of each data source are summarized on the analysis results.Then,based on IEC 61970 and 61968 standard,the unified standard interface of multi-source data of distribution network is established.Distributed network multi-source data acquisition system;and the development process used in the relevant technical specifications and problems encountered in-depth study,based on the ROA architecture developed a multi-source distribution network data service system to solve the multi-source data Unified access to the problem,and on the basis of the realization of the multi-source data acquisition system,the main function of the main application of data acquisition system real-time measurement and timing call function for multi-source data collection,the final data information results to visualize Interface,the test results in the form of PDF report to show the distribution network for further advanced application analysis to provide reliable information support.
