Abstract
Synchrophasor technology improves power grid visibility by installing phasor measurement units (PMUs) over a wide area in the power system. Big data received from PMUs contains important information about grid behavior. This information is useful in monitoring the safety and security of the grid. An extensive state-of-the-art review of big data analytics and its prime applications in power systems are expressed in this paper. It presents, a general background in data analysis techniques such as exploratory data analysis, statistical data analysis, and unsupervised data mining techniques like clustering. Two 400 kV transmission line tripping events are analyzed from the data recorded by the PMUs installed in the western part of the Indian grid i.e., Maharashtra State Electricity Transmission Company Limited (MSETCL) grid. The box plots, Correlogram, and the formation of clusters carried out for the PMU data recorded under ambient and disturbance events. This provides insights on how effective big data helps to make the right decision at right time for effective management of the power grid under normal and contingency conditions.

This section elaborates utilization of data analysis techniques described in section II with phasor measurement units (PMUs) data obtained from the among various locations in the Maharashtra State Electricity Transmission Company Limited (MSETCL) grid
PMUs are installed in India as part of a Central Government Unified Real-Time Dynamic State Measurement (URTDSM) project
Summary
Synchrophasor technology is a potential tool for diagnosing, preventing, and control for the grid system. Synchrophasor is a phasor measurement unit (PMU) used for finding the health of the power grid. The Indian power grid has taken major steps to implement smart grid technology like a wide-area measurement system (WAMS) after blackouts in the northern and north-eastern parts of India in July-2012 by launching a pilot project. Power transmission utilities have installed PMUs for the reliable wide-area monitoring, protection, and control (WAMPAC) system. The national WAMS project called Unified Real-Time Dynamic State Measurement (URTDSM) project includes the furnishing of 1740 PMUs in the transmission terminals i.e. extra-high voltage (EHV) substations across India. Thirty-two Phasor Data Concentrators (PDCs) shall be installed at the State level, Regional level, and National level
