Standards Reference
IEEE 80
Guide for Safety in AC Substation Grounding. Touch and step potential calculations, grid resistance (Schwarz equations), mesh voltage, conductor sizing for fault current.
IEC 61936-1
Power installations exceeding 1 kV AC — grounding design, earth electrode resistance, equipotential bonding, soil resistivity measurement and layer model.
IEC 60870-5
Telemetry and telecontrol protocols — SCADA interface, RTU specification, DNP3/Modbus mapping to I/O tags. IEC 61850 for substation communication architecture.
IEC 60076
Power transformers — rating, impedance, short-circuit withstand, temperature rise, noise level. Tap changer specification and neutral grounding method.
IEEE 977
IEEE Standard for Substation Lease Equipment — circuit breaker specification (symmetrical/ asymmetrical interrupting rating), contact arrangement, operating mechanism.
IEC 62271
High-voltage switchgear — SF₆/gas-insulated switchgear (GIS) specification, busbar thermal rating, insulation coordination, seismic qualification per IEC 62271-207.
What FrameAI Substation Delivers
Single-Line Diagram (SLD) Generation
Input your bus configuration, transformer ratings, and protection settings. FrameAI generates an SLD with standard IEEE/ANSI symbols — bus sections, CBs, CTs, PTs, transformers, switches. PDF output ready for client submittal.
IEEE 80 Grounding Grid Design
Input soil resistivity (Wenner 4-pin), fault current magnitude and duration, surface layer material. FrameAI calculates grid conductor size, mesh voltage, step voltage, earth electrode resistance (Schwarz), and produces a grounding plan drawing.
Equipment Specifications
Transformers, circuit breakers, disconnectors, instrument transformers, surge arresters — FrameAI generates equipment datasheets per IEC 60076 / IEC 62271 / IEEE 977 from your voltage level, current, and fault level inputs. PDF spec sheets for procurement packages.
Bus Bar Sizing — IEC 60853 / IEEE C37.20
Bus bar material, cross-section, span, collector width → ampacity per IEC 60853-1 and IEEE C37.20. Symmetrical and asymmetrical short-circuit current check, thermal limit on overload. Rigid bus and strain bus design with span sag and tension calculation.
IEC 61850 Substation Architecture
Bay level, station level, and process bus architecture per IEC 61850. FrameAI generates the SGA (Substation Configuration Language) object list, GOOSE message mapping, and SAMU (Server Application Management Unit) specification.
Lightning Protection Design
Rolling sphere method per IEC 62305-2 for substation lightning protection zone classification. Shielding angle method, air termination positioning, down conductor routing, earth termination resistance check.
