PowerFlow™ Features
The EasyPower Power Flow module includes the ability to perform analysis for all systems, including balanced and unbalanced 3-phase, single-phase, and DC equipment. All of this is provided in our powerful and intuitive Power Flow module, without the need to make additional purchases for unbalanced or DC calculations.
Intuitive System Overload and Voltage Evaluation
- Overloaded equipment instantaneously highlighted for fast sizing and verification
- Overload evaluations performed on transformers (2 and 3 winding), current-limiting reactors, cables, transmission lines, and busway
- Overload evaluation based on phase with highest load for unbalanced loading
- Buses with improper voltages are highlighted instantly for easy identification and diagnosis
- Over-voltage/under-voltage evaluation based on phase with highest /lowest voltage for unbalanced loading
- Voltage unbalance evaluation using NEMA definition LVUR, IEEE definition PVUR, or True definition VUF
- Adjustable min/max thresholds for voltage and overload violation notification
- Evaluation of negative sequence and zero sequence voltages with adjustable thresholds
Automatic Voltage Control Equipment
- Load tap changer (LTC) adjustment on 2 and 3 winding transformers, either voltage or var controlled. Fixed transformer taps are also allowed.
- Utility/generator swing voltage control for PV and PQ models
- Generator reactive var compensation for voltage control
Detailed Reports
- New tabular HTML reports itemize branch flows and loads for thorough analysis
- Output results available in phase quantities, symmetrical components or positive sequence
- One click exports to Excel, Word, Open Office, and more
Multiple Swing Sources
