Interactive single-line editor
Drag-and-drop 70+ component types onto a vector canvas with snap routing, rotation, copy/paste and full undo/redo. Wires are nodal — connectivity is always solver-ready.
PowerGridTools is an end-to-end electrical power-system design and analysis platform for AC and hybrid AC/DC networks. Draw the single-line diagram, run nine industry-grade analyses, and export standards-compliant reports — on the desktop, in the browser, or against a central analysis server.
A modern schematic editor backed by validated numerical solvers — built for utility, industrial and renewable power systems.

Newton–Raphson, Gauss–Seidel and Z-bus methods on the EJML matrix library, verified against IEEE 5/14/30/57/118-bus reference cases.
Model converters, batteries, PV and DC buses natively. Sequential and monolithic AC+DC algorithms solve coupled networks in a single study.
IEC 60909 short-circuit, IEEE 519 harmonics, IEEE 1584 arc flash and NFPA 70E hazard categories are baked into the analyses — not bolted on.
Generate multi-section PDF reports at 300/600 dpi with diagrams, data tables and result charts, plus vector SVG diagram export.
Reusable component libraries (IEC cables, IEEE generators) with searchable catalogs and property overrides keep models consistent and auditable.
Every analysis runs on the same authoritative network model — no re-entry, no re-import.
| Analysis | What it computes | Standard / method |
|---|---|---|
| Power Flow | Steady-state bus voltages, angles, branch flows and losses. AC, linear DC and unified AC/DC variants with ZIP loads and Q-limits. | Newton–Raphson · Gauss–Seidel |
| Short Circuit | Balanced and unbalanced fault currents (3φ, LG, LL, LLG) with peak, symmetrical and breaking currents via the Z-bus method. | IEC 60909 |
| Harmonics | Frequency-domain harmonic flow, THD/TDD, resonance and frequency-dependent impedance up to the 25th harmonic. | IEEE 519-2014 |
| Transient Stability | Time-domain dynamics of machines, motors, inverters and controls (AVR, governor) with rotor-angle and frequency response. | Euler · RK4 · Trapezoidal |
| Optimal Power Flow | Least-cost generation dispatch subject to power balance, voltage and thermal limits. | Constrained optimization |
| Contingency (N-1) | Automated outage enumeration of lines and generators with voltage and thermal violation screening. | N-1 security |
| Voltage Stability | PV (nose) and QV curves, maximum loadability, collapse point and reactive-reserve margins. | Continuation method |
| Arc Flash | Incident energy, arc-flash boundary and PPE hazard category at the working distance. | IEEE 1584-2018 · NFPA 70E |
| Protection Coordination | Overcurrent (50/51), distance (21) and differential (87) relay selectivity, clearing times and grading margins. | ANSI / IEC TCC |
From utility transmission to industrial drives and renewable DC microgrids — model it accurately.
