Aecom

The Role

Overview

Design and lead primary substation projects for high‑voltage transmission.

Key Responsibilities

  • transformer layout
  • single-line diagram
  • substation design
  • control protection
  • earthing design
  • fault analysis

Tasks

-Development of transformer layouts, including oil containment, busduct routing, and secondary system interfaces. -Coordination with civil teams to design and integrate foundations, steel structures, and electrical cable routes, ensuring seamless integration with the primary systems. -Preparation of single-line diagrams (SLDs), general arrangement (GA) layouts, equipment sizing, and equipment layout plans for substations and transmission systems. -Coordination with external vendors and contractors to ensure the supply and installation of equipment in accordance with design specifications and project requirements. -Preparation of electrical interconnection diagrams, termination diagrams, cable schedules, and other supporting documentation for the installation and operation of primary systems. -Design of primary substation systems, including AIS/GIS configurations, transformer installations, circuit breaker selection, busbar arrangements, switchgear layouts, and disconnectors for voltages up to 800kV. -Review and development of control and protection systems for primary substations, ensuring coordination with secondary systems and compliance with grid operator requirements. -Design of earthing systems, including grounding layouts, ground grid system design, and lightning protection systems for substations. -Development of equipment specification documents, bill of materials (BOM), and procurement support, ensuring the correct equipment is selected as per project requirements. -Preparation of designs and deliverables related to primary electrical systems for transmission and distribution projects. The tasks may encompass, but are not limited to, the following, depending on project requirements and the design phase: -Optimisation of substation layouts for new and upgraded substations, considering space constraints, equipment accessibility, and construction considerations. -Short-circuit force calculations, busbar sizing, fault current analysis, and equipment protection design, ensuring system stability and protection under fault conditions. -Detailed design and review of auxiliary systems, such as cooling systems, auxiliary power supplies, and battery systems for substations. -Design and integration of HVDC and HVAC systems, including converter stations, ensuring compatibility with the overall substation design.
