The electric power industry has been using EMS-SCADA technology for over 50 years. The industry is rapidly adopting the next generation technology for wide area measurement systems using Phasor Measurement Units (PMUs) which provide high-resolution and time-synchronized data typically at 25 or 50 frames/second for 50 Hz systems and 30 or 60 frames/second for 60 Hz system. This high resolution and time synchronized data provides grid managers, control center operators, engineers with capability to monitor grid performance and reliability at transmission level, distribution level and micro-grids by monitoring, visualizing and analyzing power system dynamics that cannot be obtained from the traditional SCADA/EMS system. PMU technology use is growing worldwide and provides applications and use cases, including:

• Oscillation Monitoring, Detection & Root Cause Diagnostics
• Grid Stress – Phase Angle Monitoring for Wide Area Situational Awareness and Grid Stability
• Event Root Cause Analysis for Real Time System Vulnerability Assessment
• Islanding Detection and Resynchronization
• Model Validation
• Event Mining to identify events by type, location, severity to guide planning and operations
• Frequency Response Analysis
• Renewables Integration
• Distribution and Micro-grid performance and analysis
• Fault Analysis

Architecture

EPG's enhanced Phasor Data Concentrator (ePDC) is a PDC to receive, time-align, concentrate, and distribute synchrophasor data in different formats with different communication methods.

PhasorSmart uses an open-source time-series database. In PhasorSmart, it is used as the visualization database for real-time displays and historical playback. Grafana is an open source visualization platform allowing users to query, visualize, and alert on synchrophasor metrics and user-defined algorithm results.

PhasorSmart in Substations

PhasorSmart is designed for use in substations for monitoring key substation equipment using data from PMUs, DFRs and other IEDs to achieve the following use cases

• Provide primary protection relay information to quickly identify the type of fault, and also to find the root cause of loss of critical equipment within substations
• Real time supervision of CTs/CVTs/PTs within substations
• In generating substations to monitor real time generator flows (real & reactive power limits), local oscillations to quickly identify the root cause
• Generator and/or substation transformer parameter monitoring such as loss of life, through fault , and over load, tap positions etc.
• Wind & Solar generator performance analysis within local substation

PhasorSmart has add-on modules for IEC 104, IEC 61850 and DNP3 that allows users to receive data from substation devices that support protocols other than C37.118.

PhasorSmart in Utilities

PhasorSmart allows users to develop algorithms using synchrophasor data from PMUs or simulated data, perform testing and validation and visualize results on graphical displays. Key uses of synchrophasor data include:

• Event Detection
• Oscillations Monitoring and Detection
• Islanding
• Anomaly Detection
• Voltage Stability
• Fault Analysis
• Distribution System Monitoring and Applications Research using Synchrophasor Data – MicroGrids, Fault Location, Load Modelling etc.

PhasorSmart can also be used by utilities as a starter synchrophasor system for visualizing synchrophasor data, historical events, simulated data etc.

PhasorSmart in Universities

PhasorSmart is designed for use in Universities and Research Centers to create a synchrophasor technology laboratory, Research new Algorithms, Perform Testing, Validation and Results Visualization. PhasorSmart is also designed for use in training by Professors and Trainers to use synchrophasor data and simulation tools to educate students on the following synchrophasor technology topics:

• Simulation of Events Using Offline or Real-time Simulators – Event Detection, Diagnosis, Corrective Action
• Event Signatures – Classification and Study of Different event types based on signatures
• Oscillations – Fundamentals, Mode Metering, Oscillation Detection, Corrective Actions
• Phase Angle Differences – Grid Stress, Line Reclosing, Island detection and Resynchronization

PhasorSmart includes 5 starter test cases inbuilt for utilizing the above use cases.
