Research on the Storage of Large-Scale Insulator Leakage Current Data Based on Hadoop

In the smart grid environment, huge volumes of data will be accumulated from the condition monitoring system of power equipment. Apache Hadoop platform is designed with high reliability and large data processing capability to meet the needs of data-intensive applications. In this paper, a Hadoop cluster is created which contains 19 nodes and is benchmarked. A case-study on distributed storage of insulator leakage current data is presented which is a useful attempt of building smart grid information platform using cloud computing technology. Our results indicate that the Hadoop and Hbase provide sufficiently high performance characteristics with regard to storage capacity, latency and throughput, and can meet the requirements of the smart grid environment.
