PGDA - Phasor Grid Dynamics Analyzer

Phasor Grid Dynamics Analyzer (PGDA) is a powerful, software analysis suite for synchrophasor data. PGDA works with multiple data sources including Historians, Relational Datababases (MS SQL, MySQL, Oracle, .dst files, .dat files, .csv files)

PGDA - Synchrophasor Offline Analysis Tool

With PGDA users can quickly and accurately analyze phasor data in order to:

Asses the health and vulnerability of a power system
Identify the root causes and effects of events
Determine a power system’s ability to withstand events
Identify and characterize system dynamics like modes

Challenging and time consuming tasks like system baselining and modal analysis can be accomplished in minutes.
Visualization tools help to convey meaningful information about complex data

PGDA is a tool that is designed for multiple types of analysis.

Dynamic Stability and Damping Analysis

Identify oscillatory modes
Characterize the stability of oscillatory modes
Evaluate damping level to assess power grid stability

Event & Disturbance Analysis

Event Analysis – temporal and spatial information
Root cause assessment - quickly determine the causes and effects of power system events like generation trips , line trips, generation-load imbalances, and other dynamic events

Dynamic Model Validation

Correlate model results with measured data
Refine model parameters and algorithms
Verify and improve dynamic models used in power system simulations to aid in planning and engineering studies

Baseline Performance

Analyze normal and abnormal performance and establish alarming limits
Examine long-term system performance and establish reliable ranges for voltage, frequency, and other system metrics

Reliability Assessment

Analyze key reliability metrics, i.e., Frequency response
