Practical Electrical Power Substation Design by Example

Most substation references give you either academic theory or
dense utility standards — and very little on how a real, buildable
design package actually comes together. This book takes a
different approach: it designs one complete substation, end to
end, and shows every step.

Using a single realistic worked example — a 115/13.8 kV ring-bus
distribution substation with two 50 MVA transformers and eight
13.8 kV feeders — the manual follows the exact sequence a working
designer uses:

• Single-line diagram development and equipment tagging
• Load calculations, transformer loading, and N-1 sizing
• Short-circuit study and breaker/switchgear duty selection
• Grounding grid design and verification to IEEE Std 80
• Lightning shielding (rolling-sphere) and surge-arrester rating
• Procurement-grade equipment specifications
• Physical layout, clearances, and general arrangement
• Cable, conduit, and raceway design
• Protection philosophy, ANSI functions, and trip logic
• Control schematics, DC trip/close circuits, and wiring
• SCADA and communications architecture and point lists
• Station service AC and a full IEEE Std 485 125 VDC battery design
• Lighting and convenience power
• The complete drawing set, schedules, and construction package

Every calculation is shown step by step in a clean, copyable
format. Every figure ties back to the same station, so the design
is traceable from the first one-line to the final SCADA point
list. Each chapter closes with a QA/QC checklist and a
common-mistakes section, and sixteen appendices provide filled
example schedules, an ASCII one-line, panel and DC schedules, a
materials BOM, and a standards/edition-year index.

Written for electrical engineers moving into substation work,
CAD designers who want stronger system understanding, protection
and SCADA engineers, and power-systems students. No prior
substation design experience is required.
