Substation Engineering & Design

Power Substation Engineering & Design

We perform greenfield & brownfield modifications (voltages 4kV up to 500kV).

• Substation Physical Design - site plan/layout, general arrangement (equipment layout), grading, foundations, steel structures, equipment replacements, bus design, elevation section views, electrical details, switch house design & layout, yard and switch house lighting design, power receptacles, fencing, grounding, lightning protection, raceway/conduit & cable schedules, bill of materials (BOM), and so on. See our physical and substation design post for more details.
• Protection & Controls (P&C) - one-lines/single line diagrams, 3-line diagrams/AC schematics, DC schematics/elementary diagrams, vendor equipment mechanism diagrams, switch house design, relay & telecom panel layout & details, wiring, cable schedules, connection diagrams, BOM, and so on. We ensure the P&C design is accurate and precise since it’s essential in protecting the power substation. See our protection and controls post for more information.
• Protective Relaying - relaying functional diagrams, relay settings & trip coordination, schematics & wiring design, trip & lockout relay schematics, relay logic diagrams, protection settings, programming, testing and implementation.
• DC Power Systems - DC battery / charger sizing and study, DC battery room design, connectivity, protection, and so on.
• Substation Major Equipment Specifications - Substation Transformers, Power Circuit Breakers, Circuit Switchers, Line-Rupters, Motor Operated Disconnects, Manual Disconnects, Station Service Transformers, Automatic Transfer Switches, CTs/PTs, Lightning Arresters (Surge Arresters), Prefabricated Switch (Control) Houses, Medium Voltage Switchgear, Panelboards, Batteries & Chargers, Switch House Lighting, Yard Lighting, Bus Type & Sizing, Raceways, Power Cables, SCADA Controls, Telecomm Equipment, Substation Network, and so on.
• Power System Studies & Arc Flash Analysis - performing power grid analysis or power system studies for planning, equipment sizing, dependability, reliability, fault analysis, smart grid, distributed generation (DG), distributed energy resources (DER); including arc flash analysis for personnel safety, adequate safety barriers and proper PPE requirements.
• Supervisory Control & Data Acquisition (SCADA) - SCADA design, equipment (RTU, I/O Modules) selection, analog points, digital points, pulse counter points, programming, testing and implementation.
• Telecommunications - transport design and connectivity, programming, and implementation of Fiber Optics, Microwave, Radio, Powerline Carrier, VOIP, and Local / Wide Area Networks (LANs/WANs).
• Cyber & Physical Security - Cyber assessments, critical asset identification, cyber network design, intrusion prevention & detection systems (IPS/IDS), data access management, physical security protection, NERC CIP requirements, cyber awareness training, pen testing, and so on.
• Engineering Field Support - Construction survey walkdowns, construction submittal reviews, RFIs (request for information), and so on.
