Design and Implementation of Real Time Data Center Access Interface Based on Big Data Technology

Big-data Platform has important applications in the power distribution system. To export data in the Real-Time Data Platform to Big Data Platform, this paper designed PostgreSQL-based access scheme. Firstly, this paper designed the overall structure, then gave design idea and main features of the FDW module, proposed customized program for the grid system to estimate the size of external tables and the SQL resolution scheme. This assessment scheme provided good support for Big Data Platform to get data from the underlying Real-Time Data Platform in a SQL way.
