The DSAToolsTM provide a complete toolset for power system planning and operational studies. In additon to rich modeling capabilities and leading-edge computational methods, the software is highly automated and can provide engineers with significant productivity improvements.
The key components in the suite, VSAT, TSAT, and SSAT, have also been designed to be used for on-line dynamic security assessment (DSA). In this mode, the software is connected directly to a power system's energy management system (EMS) and computes system security in a continuous cycle. The software provides system operators with important information about system security limits, critical contingencies, and remedial actions needed to prevent system failures.
Off-line Applications
- Voltage decline/rise assessment
- Reactive power planning
- Stability Assessment (Transient, small signal, voltage)
- Design of special protection systems
- Coordination and tuning of controls
- Determination of security limits
On-line Applications
- Assessment of system security for current operating state
- Determination of critical contingencies
- Determination of security limits
- Determination of remedial measures
