Substations & Relaying

Fred Wilson & Associates (FW&A), a CMA company, offers Substation & P&C engineering services to utility service providers, industrial clients, universities, and military facilities throughout the southeast.

Engineering for Power Substations

The firm engineers have a broad range of experience in power substation design from 5kV to 500kV and specialize in overcoming diverse substation design challenges. The firm’s engineers welcome the challenge of complex substation projects. We pride ourselves on providing an engineered product that is easy to understand, implement and construct. We provide comprehensive design solutions for Substation projects of varying complexity. Projects often include new, rebuilt and/or upgraded Power Substation equipment.

Substation engineering services include:

  • Physical station layout & design
  • Substation Bus Design
  • Substation Equipment Specifications (Autotransformers, HV Breakers, CCVTs, etc.)
  • Design of incoming and outgoing transmission and distribution lines
  • Design of lightning protection and grounding systems
  • Complete site development (including design of foundations, grading and drainage, water/sewer utilities, control building and site access roads)
  • Permitting and regulatory compliance such as Spill Prevention Control & Countermeasures (SPCC)
  • Construction & bidding engineering services

Engineering for Protective Relaying and Controls, Metering and Communications

In conjunction with substation design, FW&A provides comprehensive engineering services for protective relaying and controls in new as well as in existing substations of varying complexity. The firm engineers have a broad range of experience implementing various protective relaying schemes associated with Transmission Lines, Distribution Lines, Power Transformers, Capacitor Banks and Substation Bus. The firm engineers recognize that each client has different requirements that require some flexibility and a detailed understanding of the specific protective fundamentals. FW&A provides complete Protective Relaying and Control solutions tailored to meet our specific client’s needs.
