Digital Substation Engineering: Design, Automation, and Cybersecurity for the Modern Grid

The switchyard still obeys the same physics. Everything that carries information about it has changed.Substation design, IEC 61850 automation, and operational-technology (OT) cybersecurity are traditionally taught in silos. The result? An engineer who can size a circuit breaker might never have traced a GOOSE message's transfer-time budget. A protection specialist fluent in distance-relay zones might miss how a Sampled Values timing error creates a false differential current. And project teams often discover-weeks before energization-that mandatory security architectures were never designed into the system.Digital Substation Engineering closes this dangerous gap. Across eighteen rigorous chapters, this premium guide unites electrical design, automation, and cybersecurity into a single, connected discipline. Following US engineering practice and NERC CIP frameworks, every chapter delivers clear learning objectives, first-principle derivations, fully worked numerical examples with unit tracking, and practical problems.Master the Modern Grid: - Physical & Electrical Design: Tackle per-unit fault calculations, bus-arrangement trade-offs, and grounding-grid mesh-voltage checks.- Advanced Protection Schemes: Apply symmetrical components to standard faults, master ANSI/IEEE device functions, and map traditional relaying directly onto IEC 61850 logical nodes.- Digital Automation Architecture: Navigate process-bus latency, IEEE 1588 synchronization errors, and zero-loss redundancy networks.- OT Cybersecurity & Compliance: Translate NERC CIP regulations into actionable engineering. Deploy electronic security perimeters, firewalls, and IEC 62351/62443 protocols without breaking critical protection timing budgets.Also Covered in Depth: Merging units, SCADA gateways (DNP3/IEC 60870-5-104), the Purdue reference model, distributed energy resource (DER) interconnection (IEEE 1547), and end-to-end trip-time validation.Whether you are a practicing protection engineer, an automation specialist, or a compliance officer needing the hard engineering behind the regulations, this book provides the complete picture.Stop treating the digital substation as three separate subjects. Open Chapter 1 and build the connected understanding your projects demand.
