SSATTM is an eigenvalue-based software tool designed for analysis of small signal stability of large complex power systems. It includes a wide number of analysis functions and productivity tools, making it ideal for investigating oscillatory behavior, and for designing and tuning controls to improve system damping.
Applications
Studies of low-frequency inter-area oscillations
Analysis of local or inter-machine modes of oscillations
Design and tuning of controls
Investigation of the sensitivity of system parameters on modes of oscillations
Contingencies screening to meet damping requirement
Determination of power transfer limit to meet damping requirement
Features
Eigenvalue analysis based on analytical linearization of the system equations
Comprehensive model library including user-defined models
No limitation on system model size
Advanced and fast eigenvalue solvers
Easy-to-use graphical interface for data setup, program operation, and output analysis
Comprehensive result reports and plots
Fully compatible with other DSAToolsTM programs
Capabilities of importing data in various third party formats
