The last IEEE Power and Energy Magazine (Sep/Oct 2012) was dedicated to Data Analytics. Here is an excerpt from the introductory article by Dr. Kezunovic:
THE FEATURE ARTICLES IN THIS issue are devoted to the emerging i eld of data analytics, which is a computational capability to extract a cause-effect understanding of power system events. This knowledge gets extracted from field measurements through analytical methods and, in many cases, involves the use of various data and power system models. As it links the cause of an event with its consequence, it may be readily used by operators or in designing controllers to enhance power system operation.
Data analytics for the conversion of data to knowledge.

The power industry is experiencing an enormous expansion of computer and communication devices in substations. As a result, a massive amount of measurement data is being continuously collected, communicated, and processed. This is partly due to the need for much better monitoring capability as power system loading and complexity of operation have increased. The installation of a large number of intelligent electronic devices (IEDs) to accomplish the monitoring task has created new challenges, such as cyber and physical security, time-synchronized data storage, configuration management, and efficient visualization. Automated data analytics solutions are the key to efficient use of IED recordings. This automated process includes conversion of measurements to data, processing data to obtain information, and extraction of cause-and-effect knowledge. This article provides real-life implementation examples of data analytics developed to handle measurements from digital fault recorders (DFRs) and digital protective relays (DPRs). The discussion addresses the implementation challenges and business benefits of such solutions.
