Substation Engineering & Design

Power Substation Engineering & Design

We perform greenfield & brownfield modifications (voltages 500kV and below).

• Substation Physical Design - site plan/layout, grading, general equipment arrangement, equipment layout, equip elevations & sections, equipment details, bus design, foundations, steel structures, equipment replacements, switch house design & layout, fencing, grounding, lightning protection, conduit & cable schedules, bill of material (BOM), and so on.
• 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, panel details, wiring, cable schedules, connection diagrams, BOM, and so on. We ensure the P&C design is accurate & precise since it’s essential in protecting the power substation's major equipment.
• Protective Relaying - relaying logic functional diagrams, relay protection settings, CT connections & trip coordination, schematics & wiring design, trip & lockout relay schematics, relay programming, testing & implementation.
• DC Power Systems - DC system study & analysis, battery & charger sizing, battery room design, connectivity, protection, and so on.
• Substation Major Equipment Specifications - Substation Power 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, DC Systems - Batteries & Chargers, Switch House Power Receptacles & Lighting, Yard Power & Lighting, Bus Type & Sizing, Raceways, Power Cables, SCADA Controls, Telecomm Transport Equipment, Substation Network (WAN/LAN), and so on.
• Power System Studies & Arc Flash Analysis - performing power grid analysis & 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 & proper PPE requirements.
• Power Distribution (Overhead & Underground) & TL Design - performing overhead (OH) medium voltage (MV) line distribution & underground (UG) service distribution design according to approved specifications. We can model your UG network, duct-banks, manholes, OH pole design & TL towers.
• 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 (SONET), Microwave, Radio, Powerline Carrier, VOIP, Local / Wide Area Networks (LANs/WANs) and much more.
• 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, vendor equip drawing reviews, equip shop drawing reviews, construction submittal reviews, RFIs (request for information), and so on.
