Electrical Engineering Power System Simulation
eeSimu is power system analysis and design software for AC and DC systems. Build a visual one-line model once, then run the studies you need on it, from power flow and short circuit to arc flash and transient stability, to guide design and operation.
eeSimu runs on Windows 10 or later, in English or Chinese. Try it free for 14 days. If you need more time, contact us with your trial ID and we'll extend it.

Choose the studies you need
- Core: Power Flow, Short Circuit (AC and DC), Motor Starting voltage drop, Equipment Sizing
- Standard: Core plus Protection & Coordination, Arc Flash (AC and DC), Harmonic Analysis, Cable Ampacity, Battery Study, Sag & Tension, Power Flow time series, Motor Starting dynamics
- Advanced: Standard plus Transient Stability, EMT Simulation, Control Block Simulation, Continuation Power Flow, Optimal Power Flow, Contingency Analysis, Distribution Reliability, Composite Reliability, Generation Adequacy
- eeSimu makes it easy to build complete digital models of electrical power systems covering a wide range of AC and DC components.
- The ‘Network’ symbol represents a subnetwork, allowing users to model complex, hierarchical power systems.
- Each component can be illustrated with its name, annotation and datablock.
- Libraries of cables, overhead lines, transformers, relays, fuses, LV breakers, reclosers, batteries, PV modules and more.
- English and Chinese user interface and user guides.
