DSATools™ Online & Offline Applications
Technical Capabilities for Real-Time Monitoring and Study-Mode Simulations
DSATools™ offers dual-mode functionality—real-time dynamic security assessment (DSA) for grid operations and detailed offline simulations for power system planning. Backed by decades of field-tested deployment, this architecture supports utilities in both fast-response control environments and long-range system evaluations.
