Online DSA
SmartDSA™.Real-time assessment of power system stability limits and operational boundaries based on current system states.
SmartDSA™ assesses the security of the power system in real time and shows dispatchers how far the system is from its stability limits, enhancing grid visibility, reliability, resilience and security. Its computation engine builds a grid-level Digital Twin, so security assessment reflects the actual state of the grid.
SmartDSA™ supports standard communication protocols and integrates with SCADA, EMS and WAMS from any vendor. Its central database is generated automatically from EMS, SCADA, WAMS, PSS/E and PowerFactory data, is kept up to date with every change in the power system, and is time-stamped so that the same database serves past, present and future cases
Features
- Protocols: IEC 60870-5-101/103/104, IEEE C37.118, FTP, ICCP/TASE.2
- Central database automatically generated from EMS, SCADA, WAMS, PSS/E (.dyr, .seq) and PowerFactory (.dgs) data
- Maintenance-free, time-stamped database for current, past and future cases
- Configurable levels of data access; users can run assessments without access to power system and dynamic model data
- Grid code requirements parameterised; multiple grid code sets can be configured and compared
- Protection schemes such as SPS/RAS, 27/59 and 81 configurable
- Parallel computing for online dynamic simulation
- Ready to integrate with RAS/WAMPAC systems
Functions
- Transient Stability Assessment (TSA): ability to remain stable after large disturbances and faults
- Voltage Stability Assessment (VSA): power transfer limits considering voltage collapse points
- Oscillation Source Location (OSL): origin, amplitude, frequency and timing of sub-synchronous oscillations
- Sub-synchronous Resonance (SSR): risk of sub-synchronous resonance at thermal power plants
- Inertia and RoCoF Estimation: system and nodal RoCoF, grid and nodal inertia
- Web-based GUI for configuration and for online and offline assessment
- Radar, bar and line charts for security margins of one or several supervised areas
- Normal, Alarm and Emergency status with immediate alert when a limit reaches its warning threshold
