Solutions
For industrial plants
Keep plant networks safe and available: short-circuit duties, arc-flash hazards, protection settings and motor starts.
What you can do with PowerGridTools
- Calculate short-circuit currents to IEC 60909 or ANSI/IEEE C37 and check equipment duties.
- Calculate arc-flash incident energy to IEEE 1584-2018 and print NFPA 70E labels.
- Coordinate relays and fuses on time-current curves, and check voltage dips while large motors start.
Relevant analyses
-
AC load flow
Balanced load flow with the Newton-Raphson, Gauss-Seidel or Z-bus Gauss-Seidel method.
-
Harmonic analysis
Harmonic load flow with a compliance check of voltage and current distortion.
