Extrezing Big Data Analytics t- Improve System Distribution Reliability

Nie można znaleźć żadnych danych, ale można znaleźć kilka danych, które można znaleźć w innych przypadkach.

Co z Big Data Analytics?

Big data analytics refers to thee systematic computationy. processing, and analysis of extremely large and diverse datasets that traditional data- processing tools cannot t handle effectively. For distribution systems, these datasets originate from a wige array of sources: smart meters, dispository control andd data contrition (SCADA) systems, weathrer sensors, as heath monitors, cotiomar call logs, geographic information systems (GIS), and historical ance rec.
