Step-up and collector substation engineering up to 230 kV: single-line diagrams, general arrangement by clearances, grounding to IEEE 80, bus and conductor sizing, structures, and foundations — drawn and detailed for construction.
Substation single-line diagrams — buses, banks, and terminations.
Equipment layout by clearances — plan and elevation views.
Ground grid design to IEEE 80 (ETAP) — soil resistivity to step-and-touch.
Bus and conductor sizing — ampacity and short-circuit forces.
Dead-end, A-frame, and H-frame structures designed in PLS-POLE.
Shallow foundations (Visual Foundation) and drilled shafts (FAD Tools), to the structure reactions.
Single-line, general arrangement, plans and elevations.
Structure analysis and design.
Grounding (IEEE 80) and short-circuit analysis.
Shallow foundation design.
Drilled shaft foundation design.
Substation physical design — arrangement, grounding, bus, structures, foundations. Protection, relaying, and system studies sit with the utility or their specialist; geotechnical data is a client input.
Single-line and equipment list to the interconnection requirements.
General arrangement by clearances; grounding, bus, and structures designed to it.
Plans, elevations, grounding, structure and foundation design — detailed for construction.
Developers, IPPs, and EPCs: collector and step-up substation engineering up to 230 kV — arrangement, grounding, structures, and foundations, detailed for construction.
