DSAToolsTM Overview
The DSAToolsTM is a leading-edge suite of power system analysis tools and provides the complete assessment of system security including all forms of stability.
The DSAToolsTM provide a complete toolset for power system planning and operational studies. In addition to rich modeling capabilities and advanced computational methods, the software is packed with useful study tools so as to 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 assesses the system security in continuous cycles. An on-line DSA system provides system operators with important information about system security limits, critical contingencies, and remedial actions needed to prevent system failures.
