ETAP Version 22: A Comprehensive Guide to the Next Generation of Electrical Power System Analysis
3. User Interface (UI) & Model Explorer Overhaul
| Feature | ETAP V21 | ETAP V22 |
| :--- | :--- | :--- |
| Theme | Classic Windows | Modern Fluent UI (Dark/Light modes) |
| Panning/Zooming | CPU dependent | GPU-accelerated smooth canvas |
| Model Explorer | Flat tree | Contextual Smart Explorer (Filters by voltage, zone, or protection type) |
| Annotation | Static text | Intelligent labels (auto-update when rating changes) |
5. Design and Engineering Productivity
- Cable Sizing Manager: A new centralized interface allows for the automated sizing of cables based on load requirements, installation methods, and voltage drop constraints, ensuring compliance with NEC and IEC standards.
- Equipment Templates: Users can now create equipment templates (e.g., a standard motor starter configuration) and reuse them across projects, significantly reducing data entry time.
- DWG/DXF Integration: Improved handling of AutoCAD files allows for better background mapping and drawing exchange.
Transient Stability
The dynamic model library expanded in version 22 to include advanced inverter-based resource (IBR) models. This is critical as grids move away from synchronous generators toward renewables. New models include: etap version 22
- Generic Type 4 wind turbine models (WTG4).
- Grid-forming inverters for battery storage.
- Synchronous condenser models for weak grid support.
